Hulk vs. Sentry II- World War Hulk #5

The Sentry is Tony Stark's deus ex machina to deal with the returning Hulk's vengeance. The Hulk isn't supposed to be able to beat him... it's too bad the Hulk didn't go along with the program. The two of them fight so hard that they revert to their human forms. Bruce Banner knocks out Robert Reynolds, but his eyes still glow green with the power of the Hulk. Banner changes back into the Hulk moments later.

WINNER: Hulk, SCORE: Hulk 1, Sentry 0
