I understand there was once a story arc in Marvel where Dr. Doom and Magneto once teamed up. I was wondering if you could tell me in what issues of what comic this happened in.

I have a trading card about this somewhere. Hold on.

*checks card collection*

AHA! Apparently, this happened in "Super Villain Teamup #14" from 1977. It also says that Magneto was hypnotized with some kind of nerve gas, so the teamup wasn't really friendly. It doesn't say much else though (so don't ask me who they fought against or anything ).

I never read the conclusion, but they went after the Avengers for some reason. Magneto made Vision's blood run backwards. That had to hurt.

cool. doom and magneto would be unstopable! who could beat that!?

well....

hulk, thanos, galactus, silver surfer, any hero in the area... shall i go on
