Following our first glimpse last week at the character designs for Madhouse Studios' X-Men anime, Marvel has released screencaps, a poster and final concept art for the eagerly anticipated adaptation.

The series, which debuts April 1 on Japan's Animax television network, is set a year after the death of Jean Grey as the disbanded X-Men are summoned by Charles Xavier to find the abducted Hisako Ichiki (aka Armor) and confront the U-Men, the mutant organ-stealing cult.

X-Men is one of four Marvel anime adaptations written by Warren Ellis and produced by Madhouse. The English-language versions of Iron Man and Wolverine will premiere this summer on G4; X-Men and Blade will follow.
