Incredible Hulk#123(1970)

Following the capture of the Hulk, Reed Richards and the Fantastic Four are beginning to activate the device that is supposed to cure Bruce Banner of turning into the Hulk. Powering on the device, it appears to work and the Hulk is transformed back into Bruce Banner. When Banner revives, he refuses to participate in any tests and shows the members of the FF that he still can transform into the Hulk; however, now he can do so under his own power and still retain his Banner personality and intelligence. Although now in control, he vows never to become the Hulk again. After convincing the Fantastic Four to let him leave without further testing, Bruce calls Betty to tell her the good news and she flies to New York right away. The two renew their romance and after spending time together, Bruce proposes to Betty, who eagerly accepts. Although they live in relative bliss, Banner is still haunted by the memory of the Hulk and vows to never become that monster again if he can help it. Meanwhile, back at Gamma Base, General Ross shows Glenn Talbot the Army's latest invention, the Tripodal Observation Module (a.k.a. the TOM) a new top secret weapon that is nicknamed the Murder Module. Both of them are unaware, however, that the Hulk's old enemy, the Leader, wishes to take control of the device and is speeding toward Gamma Base to carry out that very task. Later, Betty and Bruce are called by General Ross asking Bruce to become the Hulk again in order to keep the TOM from being stolen. Bruce isn't sure what to do, but decides to go and meet Ross anyway. At the transport site, Ross apologizes to Bruce for all the hard times that he's given him over the years and consents to Bruce marrying Betty. Bruce decides to go along with the convoy and is willing to employ his powers if need be. As the convoy rolls, the Leader attacks in a specially-made jet, and uses his superior mental powers to levitate the TOM and the truck that is carrying it up into the sky. When the truck breaks free of the trailer and begins to plummet to the ground, Bruce changes into the Hulk and saves the driver, then continues after the Leader. Entering the nearby woods, the Hulk is attacked by the Leader who has activated and is now piloting the TOM. As the battle progresses the Hulk loses his temper, smashes the TOM and grabs the Leader. However, before Bruce can crush the Leader, he realizes that he has lost control and panics, allowing the Leader to struggle free and escape. Bruce then changes back to his human form and laments over the fact that he almost killed someone, and vows never to become the Hulk again, not even if his life depends on it.
