The Hulks are iconic green monsters. Their skin is green. They bleed green. Even their feces are green.
Originally, Stan Lee wanted the Hulk to be grey. Due to ink problems, Hulk's color was changed to green.
Due to the gamma radiation that birthed him, his skin is nearly indestructible and takes massive force to break. Throughout Hulk's many on-screen fights, he has only bled twice, and both circumstances prove it takes a unique set of variables to accomplish that.
In the Marvel Comics universe, Hulk's blood is depicted as being radioactive and highly toxic to non-Hulks.
In the original depiction of the Hulk, Stan Lee wanted him to be gray. However, due to ink problems, the Hulk became green. To fix this issue, Gray Hulk was introduced as the original Hulk when Bruce Banner was first hit by the Gamma Bomb, but further uses irradiated him to a not-so-healthy green.
The Red Hulk first appeared in Hulk vol. 3 #1 (January 2008), created by Jeph Loeb and Ed McGuiness, but his identity as Ross was not revealed until later. The origin of Red Hulk was revealed in Hulk #23. Red Hulk began appearing as a regular character in Avengers vol.
Due to the gamma radiation that birthed him, his skin is nearly indestructible and takes massive force to break. Throughout Hulk's many on-screen fights, he has only bled twice, and both circumstances prove it takes a unique set of variables to accomplish that.
Originally, Stan Lee wanted the Hulk to be grey, but due to ink problems, the Hulk's color turned to green. This was explained by saying that the Grey Hulk was the original Hulk to appear when Banner first got hit by the Gamma Bomb.
Combined with the Hulk's superhuman durability, it makes him exceedingly difficult to defeat or incapacitate, as noted by Wolverine during their second battle. Disease Immunity: The Hulk is completely invulnerable to all known Earth-based diseases and viruses, including AIDS.
Because of the thickness and strength of the Hulk's skin, it's nearly impossible for any form of artillery to hurt him. Sure, everyone's seen bullets bounce off of the Hulk, but when we say he's bulletproof what we really mean is he's BULLETPROOF.
As a result of the gamma radiation that created the Hulk, Bruce Banner also gained the ability to rapidly heal from injuries. Like his strength, the speed at which he can heal from wounds is connected to the level of rage he possesses.
However, just because Ghost Rider doesn't have any reason to kill the Green Goliath doesn't mean he can't, as hellfire is revealed to be the one thing that can actually kill the Hulk–and the Hulk himself confirmed it.
The Grey Hulk is actually a rather intelligent version of the Hulk. He calls himself Joe Fixit. He works as an enforcer for the mafia in Las Vegas, and gets all sorts of trouble. He's squared off against Spider-Man, Wolverine, and many more superhumans in the Marvel Universe.
Introduced in 2012's Avengers #24, the Purple Hulk is Norman Osborn, aka Spider-Man villain the Green Goblin. After the Skrull attack known as the Secret Invasion destroyed trust in existing institutions, Norman Osborn managed to replace Nick Fury's S.H.I.E.L.D. organisation with his own fascistic H.A.M.M.E.R.
As you know, Bruce is a pretty thin guy, so we assume his junk is pretty standard — but The Hulk's junk is going to be massive. This is going to make sex a real gamble because you might end up with a 20-inch-long and 7-inch-wide veiny rod of tissue in one of two orifices . . . neither of which is going to pleasant.
One idea is that the creation of Professor Hulk let Bruce's intelligence inject more humanity into the Hulk. As a result, his rage was tempered enough to affect his strength. That being said, the traditional version of the Hulk wasn't without his humanity.
So, it's more accurate to define him as a character capable of performing both heroic and villainous acts, depending on the situation. A lot -- and we mean a lot -- of bad stuff happens to the Hulk. Given the context, he can use his nearly unlimited power to save earth or innocent lives from destruction.
Bruce explains that Hulks metabolize alcohol at an incredible rate and thus cannot get drunk, thus their drinking sessions are, "All buzz, no barf." The "buzz" experienced while consuming alcohol is a stage of drunkenness. If they cannot get drunk, they cannot get a buzz.
Weakness: RAGE
While Hulk's rage makes him almost completely invulnerable and the strongest being in the entire universe, it also is a huge weakness. The increase of his power when in rage mode is massive. However, at the same time, he also loses almost all his intelligence when he grows angrier.
While Bruce is working at a bottling facility for some drink he gets cut and some of his blood goes into one of the drinks. The poor man who consume the drink is none other than Stan Lee, who has an incident.
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.
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.
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.
