Stargate: Every System Lord Ranked Worst To Best
13. Camulus
Camulus was one of the first System Lords to seek an alliance with Earth after the fall of Anubis, seeking protection from them after, he would later reveal, the almost total destruction of his forces. While joining Amaterasu and Yu on the peace talks, he gave the usual appearance of arrogance and threats to the SGC - but then asked for asylum on Earth.
While Amaterasu and Yu both branded him a traitor, he remained. However, Ba'al was not done with him.
When SG-1 disappeared on a mission through the gate, Ba'al sent word to the SGC that he would return them in exchange for Camulus. Camulus revealed that he had access to a Zero Point Module, that he had converted into a bomb - rigged to explode as soon as electricity passed through it. O'Neill, seeking the return of his team, sent Camulus through the gate to Ba'al armed with a ZPM, though not the one Camulus had rigged.
He was sent with a depleted ZPM. Ba'al later had him killed, something that Daniel Jackson was the one to reveal.
