10 Insane Times Superheroes Teamed Up With Their Worst Enemies

3. Black Panther & Namor - New Avengers

Namor might not be a villain per se, but he's certainly not a hero through and through. What's more is that his kingdom - Atlantis - has long had a rivalry with Wakanda; when prince T'Challa took on the mantle of the Black Panther, and consequently assumed leadership of the African country, that rivalry was always likely to escalate.

Come Jonathan Hickman's New Avengers series, both Namor and Black Panther were now a part of the Illuminati - a secretive cabal assembled by Mister Fantastic and Tony Stark to safeguard the Infinity Gems. Only the best and brightest in the Marvel Universe were accepted, and with both T'Challa and the Sub-Mariner fitting that criteria, both went on to play a pivotal role in the story.

Unfortunately for the team, as soon as everything began to unravel with Thanos threatening Earth once more, Wakanda and Atlantis became engulfed in war against the other. T'Challa's sister Shuri led the attacks against the undersea kingdom, but the King had to weigh up his duty to Wakanda, as well as that to humanity at large.

The two enjoy a frosty relationship for most of the arc, and their partnership eventually comes back to harm T'Challa in the end, but it made for one of the best things about Hickman's series nevertheless.
