10 Insane Times Supervillains Lost Their Powers

10. Sinestro Loses His Jewellery (More Than Once)

The Green Lanterns have fought their fair share of enemies over the years, but the one villain who could be called the Corps' worst began as one of its greatest members. Sinestro was once the Green Lantern of Space Sector 1417, which was almost entirely devoid of all crime and lawlessness.

Eventually, it was revealed that Sinestro was only able to maintain such perfection was by becoming his homeworld's harshest possible dictator, ruling his people with an iron fist. When his duplicity and evil ways were exposed, he was put on trial on Oa, and swore vengeance against Hal Jordan and the Corps.

At this time, he was stripped of his Power Ring and sent to Qward in the Anti-Matter Universe, but this only gave him the opportunity to put on a Qwardian Power Ring, which used the yellow light of fear as its power source. Over the years, Sinestro would attack Jordan and the Corps multiple times.

After the "Crisis on Infinite Earths," Sinestro was captured once more, but this time, he was stripped of his ring and imprisoned inside the Central Power Battery on Oa.

While inside, he learned the secret of the Yellow Impurity and was only released to battle Jordan, who had been taken over by Parallax, the embodiment of fear in the universe.
