Hulk

"Leave me alone!"

-Hulk to Baldur after a long, arduous fight

Hulk  is the super strong and monstrous alter ego of Bruce Banner. When Hulk and other heroes end up in Midgard, they struggle to adapt, especially Hulk, as his appearance strikes fear into the hearts of everyone he meets.

After settling in, Hulk takes up residence in the forests of Troy, as it's a relatively peaceful place, being surrounded by nothing but miles of trees.

When he comes across Kratos and Atreus, who start their journey to the mountain, he tags along with them, despite Kratos not trusting him at all, even after Hulk uses his amazing strength to fight several evil creatures, including Trolls, Ogres, and even Baldur himself.

Personality
Hulk is shown as a kind, mysterious, protective and quite romantic. He is compassionate and afraid of hurting people that he loves.

However, while extremely strong and destructive, Hulk only attacks when provoked or to protect his friends and for a time, he desired to be alone, often ending up in areas uninhabited by humans like caves or forests.

Powers

 * Enhanced Strength: Hulk's primary power is his absurd strength, which enables him to easily fight off entire armies with his bare hands or anything he can get his hands on, whether it be hurling a boulder like a bowling ball, or using an uprooted tree as a club, Hulk is undoubtedly the strongest creature in the Nine Realms, even more so than Trolls, Ogres, Draugr, and even the reanimated corpse of Thamur, a Frost Giant of Jötunheim. Hulk is even shown to be capable of fighting individuals with godly power, such as Baldur and Thor as well as his sons Magni and Modi. According to Mimir, Hulk's strength is greater than even Hercules, who has the title of "The God of Strength and Heroes".
 * Extreme Durability: Hulk's skin is extremely dense and nearly impossible to penetrate by even the strongest of weapons, making him almost impossible to defeat in battle, let alone even hurt. The only weaponry that can even hurt him is the Leviathan Axe, Atreus' magic arrows, Magni's sword, Modi's mace, and Thor's mighty hammer Mjölnir. Even if he is hurt by any of these weapons, Hulk will quickly heal from said injuries without a problem.
 * Amazing Speed: Despite his large size, Hulk is amazingly fast and agile, capable of running at a speed of 400-500 miles per hour. His speed isn't just limited to his movement speed, as he also has amazing perception, able to dodge a swing from Kratos's Leviathan Axe, deflect Atreus' normal arrows with his arms, and even counteract a surprise attack from Baldur, who had amazing speed.
 * Extreme Stamina: Hulk has high levels of stamina, which allows him to fight for several hours, if not days. His most notable feat of stamina is when he had sex with Aphrodite for over 10 hours, which broke her "beyond belief".
