Not long after Hulk was baited into a trap by the Asgardian trickster, Loki, into destroying a train trestle. This would lead to the first instance where Hulk became a team player. Beside the occasional group endeavors, Hulk has teamed-up with many others that didn't think he was so bad. Spider-Man, Power Man and Iron Fist have partnered with Hulk on several occasions. Even brutes like the Thing and scrappers like Wolverine identified with Hulk and have allied with him almost as many times as they've fought against him. Not only has Hulk befriended those in the super-hero community, but he has managed to form bonds with regular people such as "Crackajack" Jackson and Jim Wilson. Unfortunately for the Hulk, there are many who used his limited intelligence against him and attempted to manipulate him for their own selfish means. Vile menaces like the Leader, Tyrannus, and Captain Omen. When Hulk proved to be too hard to control, they sent their minions like Aquon and Mogol to confront him physically. Enemies came in all shapes and sizes, ranging in power levels. From mere humans like Devastator, to evolved beings like the Inheritor, to monstrous powerhouses like Glob, Hulk always found a way to prevail. Even against those who masqueraded as friends such as his old physics professor, Geoffrey Crawford (later known as Ravage).
