Iron Man (OU)

DUH-NUH-NUH-DUH-NUH-DUNUNUNUNUNUNUH-NUH-NAH-NAH!

Iron Man first appeared fighting for TMV. He vanished after being deemed too god-moddy.

Then he appeared fighting for Tahar'ok. Afterwards, he vanished after again being deemed too god-moddy.

Then he came back and started fighting for Yon.

Then he came back again and started fighting against the Great Beings' armies. Make your mind up, man!

Then he came back during the Battle of Neo Z'Traa and fought some Vrai. He then turned on Blackout, but was forced to retreat.

He then was chosen by Quolas's Orb of Summoning to participate in the Battle of Mordor. When he saw the immense armies of the Great Beings across the battlefield, he said "Forget this, I'm out" and flew into space. He decided to track Ultron, his old enemy, which led him to Corrantia and into a fight with him. Then SMU Iron Man showed up.

Apparently, SM Iron Man kidnapped and interrogated Iron Man in a cave. Iron Man used a BOX OF SCRAPS to fix his suit and escape. Now his life is seemingly back to normal.

Trivia

 * BZPB's Iron Man is heavily influenced by the character's Marvel Cinematic Universe incarnation, but also contains elements from other versions.
