Abraham Ellis

Colonel Abraham 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. The mission that led to some friction with Doctor Elizabeth Weir; Ellis bluntly dismissed her objections, stating that she had no authority to countermand his orders. He would later tell her that, while he knew she didn't like him (and he was "not that crazy" about her in turn), he and apologized if he had interfered with her command on Atlantis and expressed respect for her, 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 when an Asuran counterattack necessitated the city' departure from the planet Lantea. In preparation, he took all nonessential base personnel aboard the Apollo.
