Hulk could beat Superman.

The Hulk of World War Hulk is a cunning and more powerful version than the previous incarnations, for he is the insanely enraged version of the "Gravage Hulk". His rage is at its most focused, due to meditation training by his ally Hiroim. This incarnation has extremely high durability.http://media.comicvine.com... Another source of the Green Scar's strength in comparison to other versions was his lack of inner conflict, if not alliance, with Bruce Banner. There were several instances where the Hulk and Banner worked together strategically, and please note that Bruce Banner is the 4th smartest human in the world such as acting to disable Dr Strange. Caiera, the Green Scar's wife, understood Banner as well, and both personalities loved her equally. This was the driving factor in the Banner/Hulk alliance. As a result of being caught in the explosion of the warp core of his ship which brought him to Sakaar, which destroyed the planet, Green Scar's base level of strength was dramatically increased. He can lift well over 100 tons in a functionally calm emotional state. http://i663.photobucket.com... He seems to have resurfaced after Bruce regained his Hulk powers, his anger tempered from its "Worldbreaker" levels by another confrontation with Skaar, and was proven even strong enough to take down the Red Hulk without much of a fight. The Hulk recently lived up to his "Worldbreaker" title by destroying a world (from the huge amounts of gamma energy he was releasing) unintentionally in the Dark Dimension in Incredible Hulk Part 4.After being exposed to the energies from the exploding core of the ship that originally brought him to Sakaar, Green Scar's base strength level was dramatically increased. While in a calm state, this incarnation was able of lifting well over 100 tons. However, while in an enraged state, adrenaline surges through Hulk's body, magnifying his strength significantly above his base limits. Hulk's immeasurable strength is directly proportional to his level of rage, excitement, stress. The Hulk also grows stronger the more radiation and more dark magic he catalyzes. Bruce Banner subconsciously restrains the Hulk's full potential by quantifying the external variables so that Hulk does not hurt anyone. However, in case of agreement of both, the Hulk can overcome this limitation, like when he turns into the Worldbreaker. Hulk has performed impressive feats of strength throughout his career. Such as:Destroying a meteor twice the size of earth with one blowhttp://www.bamkapow.com... Lifting a mountain in his weakest Hulk formhttp://www.bamkapow.com... Punching the supposedly unmovable Blob who has his own gravitational pull http://media.comicvine.com... Not only feebly breaking superman's grip but throwing him out of orbit as well (in his weakest Hulk form) http://media.comicvine.com... Not only being able to take Glaiatior's Eye beam power (which is stronger than Superman's) but reflecting it back into his eyes.http://www.bamkapow.com... overcoming a power-draining mechanism which contained much of the combined power of himself, Doctor Strange, the Silver Surfer and NamorBeating both the Avengers and the Fantastic four at the same time.Having a Quick enough reaction time to react to Quicksilver http://media.comicvine.com... He Has limitless Strength (Base level of 100tons in a calm state), Speed (Base level of 700mph in a calm state), Stamina, And as Worldbreaker has learned to manipulate his Gamma radiation and Cosmic powress further than he did before. in fact as it is unless superman is invulnerable to Gamma radiation every time Hulk attacks he releases both Gamma and Cosmic Radiation.Now Green Scar the World breaker is a excellent strategist, since he possess the intellect of Bruce Banner, and has Fought superman before he would know what he is getting into thus out Fear, Rage, Stress or excitement (probably a mixture of all) his Gamma surge would increase to protect himself possibly raising his levels past that of Superman. Now with Bruce Banner's intellect he would mostly likely know about superman's strength and weaknesses the worlds 4th smartest man would certainly know about the effects of Kryptonite such as if he managed to get superman away from the orbit's yellow sun then he loses his powers, or finding kryptonite. Even without exploiting the weaknesses of superman as the battle draws out Hulk would eventually win since he has infinite power and Superman has Finite, Superman has a couple know weaknesses Hulk has no known weakness."Then why do you suddenly look scared? Maybe you see that you could be ten times stronger than Hulk, and it still would not matter. Not when all Hulk has to do is become ten times as mad!!" -- Hulk
