The third of the fourth series based on Marvel Comics and produced by Madhouse. This series aired in Japan on April 1st 2011 and follows the adventures of the X-Men in Japan as they confront the U-Men, a cult stealing and implanting mutant organs to strengthen their army, as they investigate the kidnapping of mutants in the area. The current team consisting of Cyclops, Wolverine, Storm, Beast, Professor X, new girl Armor and Emma Frost.Not to be confused with the 1990s animated series.
Action Girl: Storm, Emma Frost, and likely Armor as well.
Adaptational Badass: In the comics, the U-Men were slightly creepy D-list jokes, notable only for their connection to the big-name villain John Sublime. In this series, they're a major organization with considerable resources and a serious threat to the X-Men.
Adaptational Heroism: Emma Frost is portrayed as much kinder and more sympathetic here than most other versions, and most of her negative personality traits barely even show up outside of her backstory. In fact, outside of some snarking she doesn't do a single mean thing to anybody.
Art Evolution: Wolverine looks far more gruff like his comic book appearance, contrasted to the two previous anime series where he was more of a Bishōnen.
Ascended Extra: Armor gets her first leading role in an adaptation here.
In one episode, both fight off a group of mutant hunting robots while riding their bikes. Also, Wolverine does it by getting close and using his claws, Cyclops simply charges in and uses his bike's assortment of missiles and lasers.
Red Herring: Emma Frost was mainly accused (especially by Cyclops) as the one who made Jean lose her sanity with the Phoenix Force. The Emma seen by Scott was an illusion made by Mastermind knowing that Emma might join the X-Men after her departure from the Hellfire Club.
Red Oni, Blue Oni: Wolverine and Cyclops naturally have this dynamic, and Wolverine points out that when Cyke's Heroic BSOD puts Wolverine in the Blue Oni role, something is seriously wrong.
Revealing Coverup: The U-Men assassinate any police officer trying to investigate the disappearance of teenagers in Tohoku, publicly revealed as an "unfortunate death".
Sad Clown: Wolverine comes across this way with his cynical Gallows Humor, particularly if this series canonically takes place some time after the events of his own series.
