Deadpool: Samurai is a Marvel manga. I bought my copy of this volume brand new.
This review includes major spoilers.
Review:
At the end of the first volume, Deadpool and his new teammates found themselves up against a regenerated version of Thanos. That battle continues in this volume. Then it's time to travel to Mount Fuji in order to find out what Loki's cooking up there and stop him. The specifics of Loki's motive are finally revealed, and it's all just as stupid as you'd expect.
Okay, the first volume was better. Except for Deadpool, just about every Marvel superhero who showed up either behaved out-of-character or like a parody of themselves. Captain America, in particular, made me wince, although Loki was fairly disappointing too. Design-wise the most difficult to handle was Hulk, who was weirdly pretty.
