Like Deadpool and Wolverine – but way less publicized – the Hulk has the ability to grow entirely new tissue and heal from most wounds in just seconds.
As Bruce told Jen, “the way it synthesized gamma, I was able to use it to completely heal my arm.” Healing his arm then allowed him to once again become his fully integrated self, aka Smart Hulk, again which is why we see Smart Hulk's return in the series!
She-Hulk's strength magnified her gains a thousandfold and she defeated the Champion in their bout. Whether Hulk could do the same is up for debate, but it's clear that, out of hulk form, Jennifer is much stronger and better trained in combat than her cousin Bruce.
Not only is Jen now stronger, she can also emit blasts of gamma radiation which potentially make her even stronger than the Hulk. Bruce Banner isn't exactly a pushover though. In fact, many fans would assume that his Hulk is actually the strongest because he's the original.
Furthermore, though she's much taller in her She-Hulk form, Walters's body mass is just as dense as that of her normal human self. In any case, like Hulk, She-Hulk is still susceptible to outbursts of anger and becomes much stronger when enraged.
As Titania, MacPherran had an intense hatred for She-Hulk, as she defeated her during her first battle. Ever since that battle, Titania has harbored a resentment for She-Hulk, and has attacked her more than any of her other foes. Because of this, Titania is commonly known to be She-Hulk's arch-nemesis.
This might be up for debate, but Marvel has answered it in their comics. Hulk is difentiely stronger than Juggernaut. They solved this question in Juggernaut Number 2, where Cain Marko actually admits the Hulk is indeed stronger.
The Hulk may be one of Marvel's strongest superheroes, but one of the most underrated members of the X-Men, Havok, can defeat him in one simple move. Cyclops' brother, Havok, is one of the few Marvel superheroes who can defeat the Hulk in a fair fight.
Marvel fans know that Hulk seriously injured his arm after he used the “new and improved” infinity gauntlet to bring back all of the people that disappeared during the blip with a snap of his fingers.
Hulk's Healing Factor is the Strongest There Is
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.
He explains to Jennifer Walters — his cousin — that he spent years creating an inhibitor device that he wears on his arm. The device helped heal his injury a little bit, but it mostly kept him in human form all the time. Bruce and Jen are in a car accident early in the episode, and Bruce's device breaks.
Deadpool definitely has the strongest healing factor in the Marvel universe.
The Incredible Hulk's healing factor is much stronger than Wolverine and Deadpool's, as the character can officially survive decapitation!
Bulletproof
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.
While Thor himself is not strong enough to defeat Juggernaut, he has the help of his famous hammer Mjölnir. Since Mjölnir can only be wielded by the worthy, Juggernaut has no chance of lifting it.
Apocalypse. Apocalypse makes his way into this position on the list because he is technically stronger than the Hulk. He also has a multitude of other abilities, including telepathy, telekinesis, and shapeshifting. And that's just touching the surface of his powers.
However, the Venom symbiote absolutely devoured the Hulk's body, seemingly permanently. It also made the alien costume strong enough to attack and overwhelm Thor later in the issue, before finally being subdued by Black Bolt and killed by a vengeful Black Cat.
Before he can defeat him, the Immortal Hulk is stopped by the Savage Hulk, who is being emotionally manipulated by the Leader. The Immortal Hulk is beheaded by a monstrous Leader and his heart is ripped out. His corpse, alongside Banner, is taken to the Below-Place by the Leader.
Titania is the arch-nemesis of She-Hulk.
Professor Hulk has the attributes of three Hulks: Grey Hulk, Savage Hulk, and Banner. He is the weakest of all incantations because he will revert to Banner with Savage Hulk's mind if he gets too angry.
It is eventually revealed that Hulk's unborn son was able to survive his mother's death and took the name, Skaar. This version of the Hulk could, and likely would beat the Mad Titan.
