And when the Black Vortex strikes the Kree Empire, Ronan the Accuser must battle alongside the Guardians! Then, intergalactic bounty hunters are hired to target a tough, green, mean powerhouse - but there are two Marvel heroines who fit that description. And now Gamora and She-Hulk are both fighting mad! And finally, Rocket Raccoon must team up with the Pet Avengers, much to his dismay, to face some truly fowl villains! Collecting GUARDIANS TEAM-UP #1-5 and TAILS OF THE PET AVENGERS #1.
