Peter Parker was bitten by a radioactive spider and that gave him the super powers allowing him to be Spider-Man.

The son of a witch and a demon, Hellboy was born in another dimension: Hell. Born in flames, he is naturally fire resistant, super strong, and virtually invulnerable.

Together they save humanity.
