Living in the margins of the X-Men, Doop has freaked out X-Men and readers alike. However, when he gets deeply involved in X-Men business (and in the personal life of Kitty Pryde!), Doop will be thrust into the spotlight. This adventure will prove that Doop is, in fact, the most powerful X-Man! Written by co-creator Peter Milligan (X-FORCE), covers by co-creator Mike Allred (X-FORCE, FF) and innovative interior art by David Lafuente (AVENGERS, ULTIMATE SPIDER-MAN)!
