Abraham Ellis

"If you ever talk like that to someone under my command again, you will not be welcome on this base, Colonel."

- Samantha Carter

Colonel Abraham "Abe" Ellis is the commanding officer of the Earth vessel Apollo. On the Apollo's first voyage to the Pegasus Galaxy, Ellis commanded a mission to launch a preemptive strike against the Asuran homeworld using the Horizon weapons system.

Biography
The nature of Ellis' mission led to some friction with Doctor Elizabeth Weir; Ellis bluntly dismissed her objections, stating that not only did he disagree with her, but she had no authority to countermand his orders anyway. When an Asuran counterattack left the city under siege, most the senior expedition members began to display a degree of hostility toward him, if not outright dismissal. He took issue with Weir's decision to open a dialogue with the Asurans, to which Weir responded by throwing his own words back at him. He was rebuffed just as bluntly by Doctor Rodney McKay when he expressed approval for a plan to submerge the city.

Despite the bumpy start, Ellis held the Atlantis team members in considerable regard, even telling Lt. Colonel Sheppard that he, not Weir, should be in charge of the city. He also apologized to Weir for any interference with her command, acknowledging that he was used to being in charge and telling her that, while he knew she didn't like him (and was "not that crazy" about her in turn), he did respect her&mdash;which Weir noted distinguished him from others in the military.

Following the mission, Ellis and the Apollo remained in orbit over Atlantis, and was present necessitated the city's departure from the planet Lantea. In preparation, he took all nonessential base personnel aboard the Apollo.

When Atlantis dropped out of hyperspace too early, Ellis contacted Col. Samantha Carter and Dr. Bill Lee on the Midway space station, who then helped to search for the city. They later rescued Sheppard's time while they were on a mission to gain a ZPM from Asuras.

Several months later, the Apollo, together with the Daedalus, returned to Atlantis, this time upgraded with the new Asgard plasma beam weapons which they used to destroy several Asuran ships. He was quite rude to McKay during the planning and it lead to Carter threatening to kick him out of Atlantis for good and he seemed to repent at least somehat. Later the Apollo took part in the Battle of Asuras, which resulted in the destruction of the planet and most of the Pegasus Replicators, thanks to Dr. McKay's plan, which Ellis hardly believed it would work, even expressing shock at it working right in front of him although he was clearly happy. McKay expressed a desire to have seen his face when it did work.

In 2009, he was ordered to engage a ZPM powered Hive Ship before it was to reach Earth. Despite assistance from the Sun Tzu, both ships were disabled. He sent a distress signal to Atlantis, informing them that without hyperdrives, it would take at least one month until they found the nearest habitable planet.
