Lionel Pendergast

Colonel, replacing Colonel William Ronson as commander of the Earth vessel Prometheus. Following Anubis's destructive assault on Earth Pendergast and the Prometheus were given the uneasy charge of patrolling the planet for fear of Goa'uld aftershocks following the battle.

Pendergast intercepted Thor's Asgard Mothership Daniel Jackson when it arrived in Earth's solar system, at first believing it to be a possible threat.

Some time later he ordered the search of Osiris's cloaked Al'kesh in orbit of the planet. When General O'Neill became hesitant he had no choice but to not fire back, but his crew managed to transport the Stargate and SG-1 aboard before the enemy vessel entered hyperspace.

The following year, Pendergast was sent to pick up SG-1 on P4C-452 and head to Kallana to deliver a Mark IX warhead to an Ori beachhead. He maintained the ship's position when the Jaffa Gerak and a Fleet of Jaffa motherships arrived to assault the force field, and when the Ori attempted to initialize their Supergate.
