So, would you believe that in all the time I've owned :ff:, I never managed to beat the Ironman Mode in the Danger Room? Not once. The closest I'd ever come was when I used some X-Men characters (Colossus, Scott, Logan, Jean Grey), and even then I got as far as the wave with the T-Rex monsters and Pinstripe and such, with the remaining ones being Logan and Colossus. They ate it, albeit pretty slowly (curse Pinstripes ability to absorb blunt damage).
Any of you? If so, how? It's seems difficult to implement a whole lot of tactics in a game with such a wildcard value.
Superman. On a large map, so there's plenty of room to maneuver/get out of harm's way, and plenty of things to throw.
You could always totally uber it & use Superman, Supergirl, Mon-El, and Martian Manhunter (with possible substitutes by Capt. Marvel, Capt. Atom, and/or Firestorm). High HP, high Strength, decent to high Speed and Agility, good invulnerability/resistance, and non-blunt/piercing damage options (for that annoying Pinstripe). The only one that still poses a real problem is Mr. Mechanical, but with enough heat vision, freeze breath, and things to throw, it can be done.....just kind of slowly.
