World War Hulk
This version of the Hulk was a combination of efforts between Banner and the more intelligent of the green personalities. Working with Banner’s intelligence and cooperation, Hulk took control of the planet Sakaar, bringing peace to the land, marrying and even conceiving two children, Skaar and Hiro-Kala. After his kingdom was demolished, he returned to Earth to wage war on the Illuminati. The Green Scar is a very skilled fighter since on Sakaar he used various weapons as a gladiator in the arena. This particular version of the hulk also works with banner, and they use many strategies to bring down his opponents, which makes him a much more formidable foe and a great leader. The Green scar or The world War Hulk has displayed his brute force through many feats, he is by far the strongest hulk there has ever been, He was able to defeat the Fantastic Four, the X-men/X-force (simultaneously), the members of the illumination (although Black Bolt was revealed to be a skrull), Red Hulk, the unstopable Juggernaut, the Sentry himself and he even held planet Sakaar from falling apart with brute strength.
