Red Skull (Phineas and Ferb)

Red Skull is the main antagonist in the Phineas and Ferb special: ''Mission Marvel. ''

History
In the special, he teamed up with Venom, Whiplash, and MODOK and sent Whiplash and Venom to fight off Hulk, Thor, Spider-Man, and Iron Man. After the four heroes defeated the two villains, Red Skull appeared alongside MODOK to reveal his latest weapon: an anti matter device controlled by MODOK. The heroes overcome his weapon and were about to apprehend Red Skull and his comrades, until a ray from the sky zaps the heroes and drain them of their powers. This gave Red Skull and the other villains the chance to get away.

At the villain's evil lair, Red Skull was observing the video of the ray draining the heroes of their powers. Venom and Whiplash told him that they could have destroyed the heroes once and for all if they didn't retreated. Red Skull, however, tells them that it doesn't change the fact how the heroes have lost their powers. Red Skull then calls for MODOK, who explains to him that the ray came from Doofenschmirtz after he read Doofenschmirtz's online blog about it. Red Skull comments about the name Doofenschmirtz, saying that it reminds him of his cousin who married a Drusselsteinian and said she was dead to him. He then asks MODOK where to find Doofenschmirtz. MODOK informs Red Skull that Doofenschmirtz lives in Danville. Red Skull tells his comrades that they're going on an evil roadtrip, which MODOK happily called shotgun. Red Skull angrily scolds him that he doesn't fit in the shotgun position.

The villains arrive at Doofenschmirtz's evil incorporated, where Doofenschmirtz believed it was Perry the Platypus as they came, but encountered them instead. Red Skull introduced himself to Doofenschmirtz, which Doofenschmirtz comments about his face, telling him to use sunblock as he tells him he is burned to the bone.
