Trivia. Although Ross's hair is grey, the Red Hulk has got black hair, possibly due to Banner having blackish greenish hair in his Hulk transformation. Though in more recent comics he has his hair colour and moustache.
This Red Hulk was created through the combination of both gamma radiation and cosmic rays, creating a threatening red appearance. Red Hulks have been seen in both Thaddeus Ross and Betty Ross. It's a far contrast from that of the original green Hulk, but remains equally powerful.
Using radiation siphoned from the Hulk, Leader and M.O.D.O.K. transformed Ross into the Red Hulk. However, Ross didn't reveal his true identity until he came under attack by the Red She-Hulk for a second time.
Red Hulk has superhuman strength, durability, and endurance, comparable to that of the Hulk. He is capable of absorbing radiation, which his body can metabolize for increased strength. Unlike the Hulk, increased anger does not make him stronger but emit increasing heat.
Physical Appearance
Hulk is a green-skinned, hulking, and muscular humanoid with both dark olive (sometimes black) drab hair and eyebrows, bright green eyes. In Ultron Revolution, Hulk wears a dark purple in back and front with two light purple stripes along the sides and the red Avengers logo with a silver symbol.
Originally, Stan Lee wanted the Hulk to be grey. Due to ink problems, Hulk's color was changed to green. This was later changed in the story to indicate that the grey Hulk and the savage Hulk are separate dissociative identities or entities fighting for control in Bruce's subconscious.
The Hulks are iconic green monsters. Their skin is green. They bleed green. Even their feces are green.
The Hulk would win in a fight against Red Hulk. This is because his powers and abilities are amplified the angrier he becomes, and he'd, therefore, easily dispatch Red Hulk at his peak rage level. Additionally, the Hulk is stronger, faster, more invulnerable, more intelligent, and a better combatant than Red Hulk.
The Immortal Hulk outpaced nearly every other version of Bruce Banner as the Hulk. His strength was nearly unstoppable, and he gained power few other Hulks had mustered. Immortal Hulk reminded everyone what kind of monster the Hulk could become.
Red Hulk has also been shown to have a weakness to Negative Zone energy, which caused him burning pain and drained him when he attempted to absorb it.
Red was part of a film crew that was transported to Asgard by Loki. And at Loki's behest, Red took Thor's Belt of Strength and bathed in the Fires of Geirrodur before claiming Thor's Iron Gloves. The gloves were the key, since they allowed Red to lift and wield Mjolnir without being worthy.
Ross, also known as Thunderbolt Ross, and later known as the Red Hulk, is a fictional character and villain turned anti-hero in Marvel comics, appearing as an antagonist turned hero in the Hulk comics and other media.
Drain The Odinforce. After ambushing Thor, Red Hulk quickly dispatched the God. This was one of his greatest feats, given the fact that Thor is such a powerful character. It was actually even more impressive than that.
The Orange Hulk was part of the Black Legion who served Weapon Omega. He was presumably constructed by McCoy or the Sugar Man in their genetic recombinant vats. He defended the Apocalypse ship in Manhattan and attacked the last human settlement where the X-Men fell.
Other than Devil Hulk, Purple Hulk is one of the Hulk's scariest incarnations. Appearing in Peter David and Dale Keown's Incredible Hulk #371, the Purple Hulk is the result of Hulk's possession at the hangs of Shanzar, Sorcerer Supreme of the Dark Dimension.
FIXIT - WEAK. Remember that Gray Hulk might be the weakest version of the Hulk of all-time but there was one other time that Hulk went gray after that original appearance. This was when he turned into Mr. Fixit.
The Hulk has been called the strongest Avenger given his unparalleled, planet-shattering strength, but within the 2099 future of Marvel and DC's crossover universe, the Hulk would be considered the weakest Avenger (for one specific reason).
So, there you have it. Thanos beats Hulk every time, with or without the Infinity Gauntlet. But World Breaker Hulk defeats Thanos. However, Thanos could beat the Hulk if he had the Gauntlet (He could wipe out the Universe).
Just like The Savage Hulk, The Grey Hulk has increased strength, speed, and durability. His strength also increases with his rage, but to a significantly lesser degree. He is weaker than the Savage Hulk, but largely more intelligent.
Identity Basis: This incarnation represents the personality that can do all the not so nice things that Bruce was to unsure of to do himself. Tricky, manipulative, shows little thought of others make up some of his traits. Strength: This incarnation can lift approximately 75 tons.
Vibranium can also cut the Hulk due to the same reasoning as Adamantium -- they are two of the strongest metals in the world. The one thing to note is that when Hulk gets angrier, his skin becomes more durable and can then withstand even these metals.
The Hulk's skin is impervious to conventional blades, Adamantium and Vibranium being strictly the few known metals that can effectively pierce and penetrate his skin. The Hulk was even able to remove Adhesive X from his body without any injury.
In Marvel Comics it is highly unlikely that launching him into the Sun would kill him. Not for any reason other than the fact that Hulk can survive the destruction of universes, and has done so on panel more than once. The most recent example is during Incredible Hulks #635: Can Hulk destroy Coronavirus?
