Radek Zelenka is a scientist from the Czech Republic and a member of the Atlantis expedition who is assigned to the science department and also presumably the second-in-command under Chief Science Officer, Dr. Rodney McKay - however he did claim to be the head of his own department. Both Zelenka and McKay having often performed miracles with Ancient technology over the years of the expedition's operation.
Also, in times when McKay is incapacitated, Zelenka will automatically become the temporary Chief Science Officer, and at other times he appears to function as Rodney's 'second in command' in the science contingent. After McKay's capture and transformation into a Wraith, Zelenka takes up this post and is given it permanently by Richard Woolsey even after McKay returns because of the danger associated with McKay's former status as a Wraith. He is also briefly the acting commander of Atlantis when Woolsey and Sheppard are off the city, but informally defers to Samantha Carter who is in the city as the commander of the George Hammond. After the kidnapping of McKay by Queen Death, Zelenka takes his place on Atlantis Reconnaissance 1 to Sheppard's initial reluctance.
When he was only a year old, Russia occupied Prague where his family lived. His family chose to leave and they hid in abandoned factories and plants. His father, who worked in a nuclear plant, tried to take one of its trucks so they could escape to Austria. While getting fuel for the truck, Russians came to arrest them, however a Lithuanian Lieutenant let them go. (SGA: "Meltdown")
When he was young, his brother burnt down his home with one of the lit candles, forcing his family to live in a tent through the cold Czech winter until the house was rebuilt. After growing up, his sister had a son, who, as Radek pointed out "breaks things and smears thing on furniture". He also raised racing pigeons. He became a gifted scientist, and was once offered a job at Masaryk University. However, when he was offered a chance to join the Atlantis expedition, he turned down the offer at the University and joined a team going to the Pegasus Galaxy, where he was to work under Dr. Rodney McKay. He may also have a wife as well. Zelenka took part in the Velvet Revolution when he was twenty-three.
Zelenka heard rumors about the Stargate for years before actually passing through it, but dismissed the rumors. After completing his doctorate at Cambridge University, Zelenka took a temporary job at the Louvre in Paris where he went through the artifacts stored in the basements for an old professor of his who was doing a touring exhibition on the history of science with Zelenka searching for anything useful for the exhibition. Zelenka enjoyed the job greatly and eventually found a sketch of the Alpha Gate's DHD made by Vivant Denon of Napeleon's Egyptian expedition which he found in the Temples of Philae. Recognizing the device as a keyboard, Zelenka's interest was drawn and he spent months looking into it, finally finding a wild paper written by Doctor Daniel Jackson theorizing that aliens built the Egyptian pyramids which was presented by Jackson at an ill-fated conference. Jackson's paper contained a reference to the device Denon found and the line in his journals, but not the sketch which made Zelenka wonder if Jackson knew about it. Zelenka contacted Jackson who went with him to study the sketch. Jackson was excited by this visual proof of the fate of the Giza DHD and introduced Zelenka to the secret of the Stargate.

One of his first major duties was to help Major John Sheppard, Dr. Rodney McKay, Teyla Emmagan, Lt. Aiden Ford, Sgt. Markham and Sgt. Stackhouse, when their Puddle Jumper was damaged, and one of their drive pods didn't fully retract, which made them stuck halfway through the Stargate. He went to work in another Puddle Jumper to try to isolate the control pathways of the engine pod so McKay could retract the damaged pod. Zelenka managed to find a way to increase the odds of McKay's success from a one-in-a-million chance to one-in-a-thousand. (SGA: "Thirty-Eight Minutes")
After this, he proceeded to work closely with Dr. Rodney McKay on several occasions, including discovering a command sequence in the Puddle Jumper which would open the roof of the Jumper bay. (SGA: "Suspicion")
A few months later, he was working on a way to protect Atlantis from a massive storm that strikes Lantea every 20–30 years, heading its way to the city. He and Dr. Rodney McKay figured out that the storm's lightning could be used to power Atlantis' shield, but Zelenka left for Manaria, leaving McKay, Dr. Elizabeth Weir and Major John Sheppard to implement the plan before the city was taken by a Genii strike team. (SGA: "The Storm")
He was inspecting the storm-damaged parts of the city and was in the same group with Dr. Rodney McKay, Dr. Hays and Lt. Aiden Ford. He was infected with the Ancient nanovirus and did not have the Ancient Technology Activation gene, and the Ancient Technology Activation gene therapy doesn't work on him, since only 47-48% of recipients actually receive the gene successfully. The nanites were rendered inert when Major John Sheppard overloaded a Naquadah generator over the city. (SGA: "Hot Zone")
While working on what he believed to be a piece of malfunctioning technology in Stargate Operations, he inadvertently discovered Atlantis' Long range sensors. He detected three Wraith Hive Ships that were making their way to the city as well as a Wraith Dart that was entering the system. (SGA: "The Brotherhood")
When the expedition was preparing to send a message back to Stargate Command, he recorded a personal message to his family. This proved difficult for him as he revealed classified information. (SGA: "Letters from Pegasus")
When they thought they would have to evacuate the city, he devised a computer virus that would destroy the highly redundant Atlantis database, should Atlantis become lost to the expedition. Dr. Elizabeth Weir told him to save what information they have on the database. However, Zelenka told her with all the computers and data-compressing technology, only as much as 9% of it could be saved. He also aided McKay in completing the Genii A-bombs, which would be used to destroy the two Hive Ships when delivered by a cloaked Puddle Jumper that was remotely piloted using the Control chair. Unfortunately the Mark II Naquadah generator was depleted and Sheppard had to fly it himself. However, due to the timely arrival of the Daedalus Sheppard was beamed out before the Jumper destroyed the first Hive Ship. After the arrival of the Daedalus, he assisted McKay in plugging in the newly arrived Zero Point Module and raising the shield. He then used the sensors to locate Lt. Aiden Ford who had fell into the ocean. When the Long range sensors were repaired, he detected twelve more Hive Ships heading for Atlantis. When the Wraith arrived, he helped McKay convert the city's shield into a cloak. (SGA: "The Siege, Part 1", "The Siege, Part 2", "The Siege, Part 3")
When the senior members of the expedition returned to Earth, he stayed on Atlantis and discovered many new systems that had been activated after the Zero Point Module was installed. (SGA: "The Intruder")
After Dr. Rodney McKay and Lt. Laura Cadman were beamed into a Wraith Dart, he was called in to free them. With only enough power to free one life sign, he had Lt. Colonel John Sheppard choose and it ended up being McKay, Unfortunately Cadman's consciousness was transferred into McKay's mind. He then worked on fixing the damaged Wraith beaming device but was unable to regulate the power. Luckily, McKay was able to come up with a plan to use the Stargate's control crystal to regulate the power. (SGA: "Duet")
He worked alongside Dr. Rodney McKay while trying to make Project Arcturus work. While attempting to bring the power generator and weapon back online, Dr. Collins was killed when the reaction breached containment. Zelenka returned to Atlantis, and figured out why the Ancients had abandoned this technology; it was too unstable. He explained the situation to McKay, but he refused to listen to him. But after the power generator caused the destruction of 5/6 of the Doranda system, McKay apologized to him. (SGA: "Trinity")
Dr. Rodney McKay once called in Zelenka to repair the glitches on the Electromagnetic field generator on M7G-677, the planet predominantly populated with children. He was less than impressed with the proposal, reciting his experiences with his nephew. However, since the threat of a Goa'uld plot to destroy Atlantis, he was forced to stay on 677, where the inhabitants decorated his face and hair, and accepted him into their tribe. After the visit, he quickly washed it off. (SGA: "Critical Mass")
He worked with Lt. Colonel John Sheppard to help Dr. Rodney McKay, after his Puddle Jumper was sinking under the ocean. He was coaxed into sending a Jumper, to turn its cloak into a shield, so it could survive underwater, and rescue McKay, before his Jumper was either eaten by Sam, the Flagisallus, or took on too much water, which would make McKay drown. Fortunately, McKay was rescued. (SGA: "Grace Under Pressure")
He once detected a Genii nuclear reactor on Sorth that was giving radiation poisoning to the locals and going into meltdown. He was able to convince sub Commander Argan Loci to aid him in fixing the reactor and they stopped it from going critical. (SGA: "Meltdown")
When the Stargate on Taranis was destroyed by the Volcano, Dr. Elizabeth Weir ordered him to diverted the Daedalus on its way back from Earth. Later, he detected a Wraith Hive Ship on its way to Atlantis with the Long range sensors. (SGA: "Inferno")
When the Wraith proposed an alliance, they wanted the Iratus bug retrovirus to be delivered to the rest of the Wraith. Zelenka and Dr. Carson Beckett helped devise a plan by aerosolizing the gas to environmental systems of a Hive Ship, in exchange for information on Wraith technology. However, he learned of a computer virus that was able to delete all info on Wraith tech. He also discovered the virus managed to discover a way to upgrade their hyperdrives, as well as the location of Earth. (SGA: "Allies")
He then helped Major Evan Lorne in making the newly discovered Orion operational, to engage the two Hive ships in the void. During the battle, he was able to use the Drone weapons to destroy a Hive Ship, at the cost of the ship's shields. The Orion was destroyed, but Radek and the crew were beamed to Daedalus first. He then worked with Dr. Rodney McKay to fix the Life support systems on the Daedalus. (SGA: "No Man's Land")
He once detected a Wraith Hive Ship moving towards the same Black Hole the Odyssey was near, as her crew attempted to dial the Ori Supergate from the Pegasus Galaxy. Zelenka was unable to warn the Odyssey due to interference from the black hole, but Dr. Elizabeth Weir successfully relayed the message through Stargate Command. (SG1: "The Pegasus Project")
With the help of Jeannie Miller, Dr. Rodney McKay's sister, he was able to use her calculations on bridging alternate realities to perfect Project Arcturus in Atlantis. Jeannie was impressed and complimented him on his good work. When the experiment got out of hand, he worked with McKay and Rod to find a solution. (SGA: "McKay and Mrs. Miller")
Later, when some of the Lanteans aboard the Tria came back to reclaim the city, the entire expedition was forced to leave. Radek was thinking of taking up the offer to work at Masaryk University. (SGA: "The Return, Part 1")
After the Atlantis expedition returned to Atlantis after the thwarted Asuran attack, he and Ronon Dex went on a camping trip to the mainland. He preformed ground-penetrating radar tests to test the dielectric permittivity of the region's subsurface. This angered Ronon as it scared off the game he came to hunt. When a group of Flagisallus surrounded Atlantis and their sonar began causing damage to the Atlantis expedition, he worked with Dr. Rodney McKay to stop the Coronal mass ejection that was about to destroy Atlantis. (SGA: "Echoes")
While attempting to learn about the Ascension machine Dr. Rodney McKay was zapped with, a power surge forced Radek to flee, but a bolt of electricity severely wounded him. However, McKay, with his new found abilities, was able to use his healing powers to heal him. Zelenka was touched by what McKay did and promised to keep working to find a solution. As McKay knew he was going to die soon, he made some amends with Zelenka for the way he treats him, leaving Zelenka shocked. (SGA: "Tao of Rodney")
Later, when learning of a simulation Dr. Rodney McKay and Lt. Colonel John Sheppard were "playing", he did the same with Major Evan Lorne on another planet, until an argument between them forced Dr. Elizabeth Weir to ban the activity. During their game, Lorne and Zelenka seemed to share a relationship similar to the one between McKay and Sheppard. (SGA: "The Game")
On the mandatory rest day, he was playing chess when Dr. Carson Beckett asked him to go fishing with him because Dr. Rodney McKay canceled on him. Unfortunately, for Beckett he declined. After Dr. Harriet Hewston exploded, he was sent in to determine the cause. When Beckett died, he was one of his pallbearers to take the coffin back to Earth. (SGA: "Sunday")
He later accompanied a science team to explore the Ancient Mobile drilling platform located at the bottom of Lantea's ocean. After a Wraith Queen activated the emergency forcefields throughout the base, he worked with Dr. Rodney McKay to deactivate them. (SGA: "Submersion")
He was instrumental in the attempts to repair Atlantis when it was stranded in space, after the Asuran Stargate satellite damaged the city's power conduits. He attempted to patch them up with secondary conduits to activate the Stardrive again. However, after passing an asteroid belt, the stardrive crystals were damaged, and he had to fix it. However, in the process, a micro asteroid hits him in the leg, but did not hit a major artery, and recovered enough to walk, and helped McKay build a hyperdrive in a Puddle Jumper, which was used to steal a Zero Point Module from M7R-227. (SGA: "Adrift", "Lifeline")
During the city's bout with the homicidal alien entity, he traveled to M3X-387 to collect a crystal with a live entity inside. Once back on Atlantis, he helped Dr. Rodney McKay find a way to force it back into its crystal. (SGA: "Doppelganger")
During the Kirsan fever outbreak, Colonel Samantha Carter ordered Radek to remove the Stargate's Control crystal, as Gate travel was suspended. However, he started to lose his memories, and became paranoid when Major Evan Lorne and his team searched for him. He was able to knock one out and acquired a Wraith handblaster. However, he helped Carter and Dr. Rodney McKay, who also lost their memories, to save Teyla Emmagan, and stop the outbreak, by aerosolizing the Enchuri plant, curing the entire city. (SGA: "Tabula Rasa")
He then began working with Dr. Rodney McKay in his effort to shut down the Asurans attack code. When they hit a block, he urged McKay to contact his sister Jeannie Miller for help. (SGA: "Miller's Crossing")
A short time later, he helped Dr. Rodney McKay develop a tracking system for Asuran Aurora-class battleships from the Core drive that was given to them by the Organic Asuran copies of the team. (SGA: "This Mortal Coil")
After the completion of the tracking system, he moved on to the creation of the nanite block intended to fuse all Asurans together. This proved difficult and then he was summoned to Section Seven to repair the Naquadah generators. When he returned, Dr. Rodney McKay had given up on creating a block and created FRAN instead. (SGA: "Be All My Sins Remember'd")
He was stuck with Colonel Samantha Carter in one of Atlantis' transporters during a false quarantine lockdown. Major Evan Lorne and Lt. Colonel John Sheppard were able to free them. When he learned of the city's self-destruct being activated, he went through the city's air vents, and went to the Main power room to deactivate the power and save the city. (SGA: "Quarantine")
After Dr. Jennifer Keller was infected with a Wraith pathogen, and grew to the power conduits, Radek attempted to stop this and look at the damage the tendrils caused. However, one of them took a hold of him, and tried to kill him, but was saved by Teyla Emmagan, who shot the tendrils, releasing him. (SGA: "The Seed")
During the events when a Daedalus appeared above M35-117, Zelenka was observing the alternate Daedalus from Stargate Operations with Major Evan Lorne and stood as lookout for them. After a few hours, the alternate Daedalus reappeared and Lorne and Zelenka took a Puddle Jumper and "picked up" Lt. Colonel John Sheppard's team. (SGA: "The Daedalus Variations")
When a Puddle Jumper lost power because of a power surge on its way back to Atlantis, he and Dr. Rodney McKay could not find anything wrong with it. When Atlantis began to suffer from the same malfunction, he worked in the Main power room and the scientist next to him was killed by a bolt of energy. (SGA: "Ghost in the Machine")
After Admah is located, Zelenka attempts to dial the planet, but is unable to receive a lock for Sheppard's team's check in. Zelenka works on figuring out why Atlantis is unable to connect to Admah and discovers a message hidden by McKay in the signal blocking the lock. As McKay expected, Zelenka is able to decipher the message and discovers it states that Sheppard's team will make their way to M3T-842. Zelenka quickly informs Woolsey who dispatches Major Lorne's team and the Daedalus to help. (SGA: "Brimstone")
When the Vanir attacked Atlantis, he attempted to remove the Armored exoskeleton of the deceased invader but triggered the self-destruct. He then discovered the location of Dr. Rodney McKay and Dr. Daniel Jackson. He dialed the Stargate to a planet that was close to the Daedalus so Lt. Colonel John Sheppard and Teyla Emmagan could contact them. When he finished dialing, he detected a buildup of power in the Gate. He determined it would overload and explode in less than a minute. Sheppard ordered him to collapse Atlantis' shield around the Gate. Unfortunately, the shield emitters began to fry and failed before the blast had completely subsided with he and Sheppard still in Stargate Operations but they were able to move to the balcony and only suffered minor injures. Shortly after, Katana Labrea arrived and offered to take Sheppard and him to M6H-987 in her her ship. He worked with the ship's chief engineer, Mila, to upgrade the Hyperdrive and beat the Daedalus there. They were successful but the drive was almost burned out. (SGA: "First Contact", "The Lost Tribe")
When Michael Kenmore invaded Atlantis, he was sent to the Main power room by Dr. Rodney McKay and Lt. Colonel John Sheppard to restore power to the city. He was able to get power to McKay's lab and some transporters. Later, he was able to crack some of the lockout codes Michael implemented and drop the Stargate shield so McKay could destroy Michael's Puddle Jumper with the Unstable vortex of the Stargate. (SGA: "The Prodigal")
He startled thief and murderer Neeva Casol, who was in Dr. Jennifer Keller's body at the time, though she was at first unaware of it. Zelenka suspected she did not feel very well and insisted she come into the infirmary. However, thinking she was caught for her crimes, she picked up a pair of pliers and stabbed him in the side, lacerating his liver. Expedition members soon learn of this, and attempted surgery. Dr. McBride was able to stop the bleeding, and he was in a light coma, but fortunately, he would make a full recovery. After Keller got her body back, she apologized to him, but he insisted it wasn't her fault. (SGA: "Identity")
After a while, Todd contacted Atlantis to apprise them that there is a Zero Point Module powered Super-hive in the Pegasus Galaxy. After Daedalus defeat at the Hive Ship, Lt. Colonel John Sheppard convinced Todd to tell the location of two ZPM's he acquired from the Asuras. He worked to integrate the ZPM's into Atlantis' power in order to fly it to Earth. When Atlantis dropped out of hyperspace, Richard Woolsey ordered him to recalibrate the Stargate so he could inform Stargate Command of the situation. Once they dialed the Gate and realized they were connected to the Hive, Woolsey sent Major Evan Lorne, Ronon Dex, Dr. Rodney McKay, and Teyla Emmagan were sent on a mission to conduct sabotage. Zelenka then informs Woolsey that the city's Wormhole drive could get them to Earth in seconds but the calculations were very complex and a slight miscalculation could vaporize the city instantly. Woolsey agreed they had no choice and ordered him to activate it. Fortunately, Zelenka's calculations were correct and they arrived on Earth in time to stop the Hive from attacking and allowed Sheppard to detonate his Nuclear warhead and escape to the Alpha Site. (SGA: "Enemy at the Gate")
Following the return of Atlantis to Earth, Zelenka started considering taking a position at a university and was somewhat cynical about the way General Jack O'Neill took over the city. However, Zelenka changed his mind when he noticed that O'Neill was stocking the city with supplies it wouldn't need if it was staying on Earth and was prioritizing repairs to the hyperdrive. Zelenka's choice to stay proved to be correct as O'Neill had been conspiring with Carter and Woolsey to get Atlantis back to the Pegasus Galaxy. When Atlantis dropped out of hyperspace prematurely, Zelenka located her new planet and ran himself to exhaustion doing so.
After McKay is kidnapped by the Wraith during the Raid on New Athos, Zelenka travels to New Athos to examine the Stargate for the last gate addresses dialed in hopes of finding a clue to McKay's location. With the help of Teyla and Halling, Zelenka is able to narrow the search from thirty-seven possibilities to nine. (SGA: "Legacy: Homecoming")
Over the next few days, Zelenka joins Sheppard's team as they examine the nine Stargate addresses. Finally, they are able to identify M40-P36 as the correct planet as it is uninhabited and the Stargate has dialed New Athos only in the last six months. The team realizes that the Wraith Darts had been sent from a hive ship in orbit which had used the planet as a base for the attack and is now long gone. With nothing more to be gained from the Stargate addresses taken from New Athos, Woolsey decides to enlist the Genii and Todd's help in locating McKay using their information sources. While McKay is missing, Zelenka is assigned to take his place as Atlantis' Chief Science Officer.
Over the next few days, as Sheppard, Teyla, Beckett, Ronon and Keller work to negotiate with the Genii and Todd, Zelenka works with Major Evan Lorne to deal with the problems caused by giant chunks of ice hitting the city and the malfunctioning short-range sensors as well as trying to get rid of all of McKay's backdoors into Atlantis' computer system. During this time, Zelenka is surprised and irritated when Lorne's team discovers a flock of pigeons that made Atlantis their home while the city was landed on Earth, a few of which one of Lorne's men killed in surprise. After Lorne clears the ice off of the short-range sensors and destroys the mini-iceberg that hit the city, Zelenka is able to restore most of the short-range sensors, but has issues with the Atlantis underwater scanners still. Zelenka also determines that while Atlantis has a low-tech means of ice defense, it is not properly deploying.
After a brief conversation with Doctor Eva Robinson in the mess hall, Zelenka is called in when a hyperspace window is detected and alerts Lorne, who was examining the bottom of the city for him in a Puddle Jumper, to be ready for water rescue when it turns out to be Sheppard in a salvaged and barely-flyable Lantean cruiser. To their relief, Sheppard is able to land the ship safely and Zelenka and Doctor Miko Kusanagi work on repairing the ship's hull breaches so that it can be flown to the Genii homeworld as part of their deal with Ladon Radim for the Genii's help.
Under pressure from Woolsey, Sheppard reluctantly agrees to assign Zelenka to the First Atlantis Reconnaissance Team as McKay's replacement until he can be found and rescued which Zelenka isn't any happier about than Sheppard. As part of his new role, Zelenka undergoes firearms training with Ronon Dex who realizes that even with his glasses, Zelenka has very poor vision which Zelenka admits to not getting fixed out of fear that he would be sent home due to IOA regulations. To get around this, Sheppard has a doctor on the George Hammond give Zelenka an eye exam and update his prescription which makes his vision 20/30. While Keller learns of this, she lets it go as they need Zelenka and having slightly bad vision won't cause any harm.
After determining that three of Atlantis' underwater scanners have been damaged and are preventing the deployment of Atlantis' ice defenses, Zelenka has an engineering team manufacture replacements and guides a team led by Lorne in replacing the sensors. Once the repair is done, Atlantis' ice defenses extend, eliminating much of the threat the city faces from the ice on the planet. Zelenka briefs Woolsey on the news and asks that he request Jeannie Miller come out on the Daedalus to help him find and eliminate all of McKay's backdoors. Zelenka takes part in the briefing for the rescue mission of McKay based on the intelligence Todd is able to get them, but stays behind at Sheppard's request as its a straight-up combat mission and the team won't need Zelenka's skills on it. (SGA: "The Lost")
- In one alternate reality, he was getting along with McKay of that reality, known better as "Rod", and Radek even taught him some Czech. (SGA: "McKay and Mrs. Miller")
- In another alternate reality, he was working with Dr. Rodney McKay at Area 51 to find the Wraith that crashed on Earth. (SGA: "Vegas")
- In an alternate timeline, Radek Zelenka traveled to Atlantis, while the power began to fail and the city began to be flooded by the ocean. He was radioed by Major John Sheppard to check out a Puddle Jumper different from the others. Zelenka, Sheppard, and Dr. Elizabeth Weir were thrown back in time to the siege of Atlantis by the Wraith at the end of the Lantean-Wraith war. They came under attack by a pair of Wraith Darts and were shot down. Zelenka and Sheppard were killed in the crash, but Weir survived. (SGA: "Before I Sleep")
- In an alternate timeline, he may or may not have been helping Dr. Rodney McKay and Colonel Samantha Carter build the Phoenix, since McKay was "too busy to remember", although he was seen delivering him a coffee and working on the ship in the background as McKay and Carter toured it. (SGA: "The Last Man")
|Appearances for Radek Zelenka|
In chronological order:
Radek works under Rodney McKay, who at first, doesn't remember his name, but eventually does. He also has to put up with all of McKay's condescending behavior, but seems very patient with him, most of the time, venting generally in Czech when he can stand it no longer. He is also very intelligent, and claims that no one can beat him in Chess. Despite that, McKay still thinks he is not as intelligent as he is, but did once acknowledge his intelligence. Zelenka also heads his own group, but McKay however, refers to his group as the "B team". He is highly respected among his peers, but is a socially awkward person. Dr. Keller once pointed out that she found it a little weird when he kept complimenting her on the smell of her hair. However, it should be noted that he is among the most resourceful and competent Atlantis personnel even under seemingly impossible conditions, as shown when he is the only known member of the expedition not to be caught at any time by the soldiers during the Kirsan fever outbreak, despite the near-complete loss of episodic memory. (SGA: "Thirty-Eight Minutes", "Tao of Rodney", "Sunday", "Trio", "The Seed", "Tabula Rasa")
Following the kidnapping of McKay by Queen Death, Zelenka joined the First Atlantis Reconnaissance Team and as such became more willing to go on missions, often displaying a great deal of bravery despite his initial reluctance at going on missions. During the Second Battle of Atlantis, Zelenka volunteered himself to go on a dangerous mission a Wraith cruiser repurposed as a fire ship and was surprised at how easily he'd settled into the role of going on dangerous missions. When Teyla ordered him off the ship as she boarded Queen Death's ship, Zelenka volunteered to stay behind on the cruiser to aid the Wraith Ember in any way he could despite the tremendous danger to himself. (SGA: "Legacy")
Radek's first language is Czech, and he often has his outbursts, when he is either surprised, panicked, or frustrated, the last being most frequently provoked by McKay and his condescension.

We.... we were.... we were scared. That was incredible, what happened? And that noise. The whole city was shaking, it was like an earthquake. That was so incredible. And then we're moving. The whole city was rising. It was rising up, rising up to the surface. It was, it was really incredible and, and, and... the towers broke through the surface and we shot up onto the surface. Water, waves, waterfalls were falling down from those heights. And we... we shot up, right to the top. Sun... just shining... It was streaming in through all the windows. I'll remember it for the rest of my life... for the rest of my life. (SGA: "Letters from Pegasus")

- Zaplať Pánbůh.: Thank goodness. (lit.: "May God our Lord reward this.", though the original religious connotation of the phrase has mostly dissipated through frequent commonplace use by the modern day, to the point that the composite "Pánbůh" (from "pán" - here "lord", and "Bůh" - "God") is now considered too colloquial for addressing God in formal prayer or service) (SGA: "Echoes")
- Tak takhle to nejde teda, tohle je na prd.: Well this doesn't work; this is useless. (lit.: "(...) this ain't good for jack") (SGA: "Tao of Rodney")
- Já s ním nebudu dělat. Já se už na to můžu vysrat.: I'm not gonna work with him. Screw this!
- Second sentence literally says "I might as well take a dump on this" (sanitized), containing the phrase "vysrat se na (...)", which is a vulgar expression of frustration used in contexts where an English speaker would use "Screw it (- this; - sth.)" or a more profane equivalent.

Behind the scenes
- David Nykl was born in Prague in what was then Czechoslovakia.
- Nykl originally auditioned for a role of a Russian character. However, due to his Czech background, the producers gave him a Czech part.
- He was originally given the part of Zelenka for just one episode. However, due to good reception from the fans and the Atlantis production team, his status was upgraded to a recurring character.
- Stargate SG-1 and Stargate Atlantis both aired in the Czech Republic and have acquired a sizeable fan following there. When the character of Zelenka was introduced, he (and actor David Nykl) predictably became the darling of the Czech fans (more so because it is quite unusual to have a Czech character on an American TV show).
- In a deleted scene in season 5, Radek is seen arguing with Rodney McKay over the use of the 9th chevron, arguing it could send someone across the universe . (SGA: "The Shrine")
- Along with John Sheppard, Rodney McKay, Elizabeth Weir, Teyla Emmagan, Samantha Carter, Chuck and Walter Harriman, he is one of only eight characters to appear in all five seasons of Stargate: Atlantis. However, Carson Beckett appears in Season One to Three while his clone appears in Seasons Four and Five.
- In the Legacy series, Zelenka seems to informally take McKay's position on Sheppard's team, going on several missions with them to rescue McKay. He later takes part in the final battle with the Wraith, boarding an explosive-laden Wraith cruiser to disarm the bombs and aiding Ember in draining power from Queen Death's hive ship. During this series, he also receives the name He Who Is Son of a Great Ruler when Teyla introduces Zelenka to a group of Wraith on Guide's hive while in her disguise as the Wraith Queen Steelflower.
