Lockjaw and the Pet Avengers

In 2009, Marvel let the pets take center stage with this lighthearted one-shot from writer Chris Eliopoulos and artists Colleen Coover and Ig Guara. The story follows Lockjaw, the Inhumans' giant teleporting bulldog, as he assembles a team of animal heroes for a mission only they can handle. It's a charming, all-ages romp that proves even Marvel's four-legged friends have the heart of a hero.
