Kotah's sword

Kotah's sword is the weapon used by the giant Android Kotah.

Overview
The sword is a high-power energy weapon capable of firing energy so potent it can destroy a Goa'uld ship with a single shot. It also has a range that's atleast capable of blasting a ship in space from a planet's surface.

In appearance, the overall size of the sword is massive, with its length being much greater than a human's height. The colour of the sword's grip is silver and the blade is silver-white when inactive. The blade glows yellow when it's channeling energy.

History
The sword was used by the android Kotah, who guarded the Ancient's temple vaults and their Stargate on the Ancient Treasure planet.

Kotah used the sword's energy attack on System Lord Sobek's ship and destroyed it, when the goa'uld fired upon the central temple.

Kotah also used the sword to kill any treasure hunters who attempted to leave the planet. One such victim was Canno, who was stabbed by the blade when he tried to make it through the stargate.

When Dr. Daniel Jackson removed Kotah's energy source, the sword deactivated along with the android.
