The Forbidden Hero Appears? - S1.E27

While out getting chimichangas and money, Deadpool encounters King Cobra at a "villain joint", defeats him and takes Iron Fist's DISK. Later, he shows up at Avengers headquarters, offering the DISK in return for becoming the leader of the Avengers. King Cobra shows up with Cottonmouth and Diamondback of the Serpent Society, wanting the DISK back. Deadpool (with the backing of the Avengers) easily defeats and the kids D-Secure them. The team refuses his request and he leaves, replacing the captured DISKs with joke fakes. Later, Tiger Shark shows up, wanting him to turn on the Avengers. He is refused and is about to attack Deadpool, when the Avengers show up. They had planted a tracker on his uniform when he was in the shower. Tiger Shark is about to attack them all, despite their bluff of using Iron Man's new armor, when Red Skull D-Secures him, having warned him to stay away from the Avengers.
