10 Insane Times Superheroes Teamed Up With Their Worst Enemies

10. Thor & Loki - The Surtur Saga

Of all the 'hero joins villain' team-ups going, Thor and Loki are by far the most famous. The Asgardian duo have the dynamism of Chris Hemsworth and Tom Hiddleston to thank for that, but while the pair have captivated for years on the big screen, they've done so for longer in the comics themselves.

Loki, for a great period of his history, was far less ambiguous than his silver screen counterpart. However, in the finale to Walt Simonson's Surtur Saga in Thor #353, the Trickster god's good streak did begin to break through.

The issue itself sees the brothers team-up alongside Odin to vanquish the world-ending threat posed by Surture as he attempts to reunite with the Eternal Flame. It ends in tears, with Odin falling into the pit alongside Surtur, but there's no denying the image of the All-Father fighting alongside his sons is also one of Marvel's best.
