The Iron Avenger
1. Thor - In the multiple times they have fought Ironman has either been dominant in the fight, or held his own. The recent fight was a Thor wanker - never before has lightning caused Ironman problems like that, he always absorbs the energy and becomes stronger - but taking it into account I will say three Ironmen.

2. Hulk - Nanites ftw. The only reason he lost last time was because the canister was empty. One Ironman (Tony Stark himself) is all that is needed. He could always do the Iron trick again.

3. Storm - The least experienced of the team can still take her. But seriously, just one.
4. Magneto - Iron Man has made it so Magneto cannot control his armor. Human frequency shut down ftw. One Ironman should be enough, but two works.

5. Dr. Doom - Tough battle, but seeing as Ironman has fought with Doom plenty of times he should know what to expect. Ill say two Ironmen just to be sure.
6. Juggernaut - One is enough. Not through raw power, but through tactics. Hit the floor underneath him, and go with sonics (human frequency shut down should work).
