Behemoth (Earth-5192)

The Behemoth was an Ogdru Hem, a spawn of the Ogdru Jahad, originating from Red Skull's dying body after he nearly succeeded in opening a new portal to unleash the Seven Gods of Chaos.

Birth
After Red Skull's return from the Chaos Realm with the help of Madame Hydra and Iron Cross, he was trusted with carrying the spawn of his gods, the Ogdru Hem, which was Behemoth, inside his body, to both protect it and guide Schmidt into freeing the Gods of Chaos. As the Behemoth was inside Red Skull's body, the former SS commander effectively became an immortal, only being able to die for some moments before he could return even stronger.

Emergence and Death
As Skull and Madame Hydra neared the completion of the original HYDRA's plan with the help of the ancient portal of Project Ragnarök in East Germany, the Behemoth allowed itself to escape from Schmidt's body in an attempt to kill Captain America, Black Widow and Fire, growing enormous in size and crushing both Red Skull and Madame Hydra after they failed to return the Ogdru Jahad. It almost succeeded in destroying the Captain, but he was able to stop them with the help of both Widow and Fire who set the old shrine to crumble and smash the Behemoth, killing it and HYDRA's decades-old plan.
