Avengers

When Wundagore Mountain falls to Exodus and his fanatical Acolytes, the High Evolutionary puts the mercurial mutant in charge of the evolved beasts known as the Knights of Wundagore. Now, the newly honored "Sir Pietro" leads these animals-turned-New Men out into an unfamiliar world, and straight into an encounter with Thundra and Arkon! But when the heroes return, and Quicksilver is reunited with his sister the Scarlet Witch, his ex-wife Crystal, and the other Avengers and Inhumans, it all races to a chaotic climax and a Siege of Wundagore - as Pietro joins the Heroes For Hire in final battle with Exodus, his Acolytes, and the resurgent High Evolutionary!
