10 Insane Times Superheroes Teamed Up With Their Worst Enemies

2. Doctor Strange & Doctor Doom - Triumph And Torment

There's a long list of genuinely great tales centred around Doctor Strange and Doctor Doom, but had you asked Marvel if the pair would've intersected two decades ago, the answer would've probably been a 'no'.

Apart from their affinity for the mystic arts (and their titles), Doctor Strange and Doctor Doom had no reason to intersect. The former, of course, was busy with the original Defenders, and the latter was a Fantastic Four villain through and through.

However, in 1989's Triumph and Torment, Roger Stern and Mike Mignola collaborated to tell a truly unique tale centred around Marvel's two most preeminent mystics. Doom enlists the Sorcerer Supreme to travel with him to Hell in order end a long running feud with Mephisto, and visually speaking, there isn't a Marvel comic quite like it.

It's a great tale, and while the Doom/Strange partnership isn't particularly famous, it's undeniably one of Marvel's best.
