Gamma Corps #4 - Hulk vs. Grey II
Hulk beats Grey by playing with his emotions. Grey says that he doesn't care about why the Hulk may have killed (mind controlled or what have you), but Hulk pushes Grey's buttons and gets him to do exactly what he wants him to do... destroy Ryker's facility. Grey is out of control and may have killed someone just the way he was mad at the Hulk.
WINNER: Hulk, Score: Hulk 1, Grey 1
