Hulk vs. Iron Man VIII- Iron Man #132

Iron Man comes darn close to actually beating the Hulk. He knocks the Hulk out... and would have gotten a mark in the win column, but he used up every iota of energy in his suit to do it and rendered himself powerless beating the Hulk. In fact he nearly killed himself.

WINNER: none, SCORE: remains Hulk 1, Iron Man 0
