text: 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 off 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.
