Amadeus Cho - Kerberos ("Kirby") The Coyote

Kerberos ("Kirby") The Coyote

Amadeus was once usually accompanied by a coyote pup who peered out the front of Cho's jacket. He picked him up along the side of the road, near a roadside diner where he met the Hulk for the first time. The coyote's mother had been hit and killed by a car, but the pup had remained with her body. Cho, not failing to see the similarity, took him in. Cho has since trained him to distract opponents and perform simple search operations.

Kerberos' name was chosen in a contest held by the writers of the comic; the winner was a reader from Montevideo, Uruguay, Martín "MaGnUs" Pérez. The name was chosen by the reader both because of the mythological connotations and the computer network authentication protocol of the same name.

During the Secret Invasion, it was revealed that Kirby was abducted immediately following World War Hulk by Skrulls posing as S.H.I.E.L.D. agents after they knocked out Amadeus with gas; Kirby was then replaced with a Skrull agent. The infiltrator was able to destroy the ship by driving it of course after disguising himself as Cho. He is slain by Cho's ally, Aton, who sees him transform back to Kirby and bites his head off. Using a tracking system he had implanted in the pup beforehand, Amadeus manages to track Kirby down, finding him in the Mojave desert. Once there, he discovers that the now full-grown Kirby has adapted to the wild, even gaining a mate. Amadeus decides to leave Kirby where he is, reasoning that his life had become too dangerous for him.
