The Incredible Hulks #627
MR. & MRS. HULK, Part 2
See the Hulk as you've never seen him before: as an international super-spy! With Amadeus Cho as his guide, Hulk dons a tuxedo and enters into a world of espionage, only to find his opponent is...Red She-Hulk? And what happens when Betty finds a new man? Hint: it doesn't really go over that well...especially when that man is one of the Hulk's oldest foes!
