Iron Man

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!
