Eat-Man is a manga by Akihito Yoshitomi, serialized monthly in Dengeki Comics GAO! Anthology. Eat-Man follows the adventures of Bolt Crank a man who has the ability to eat anything(and I do mean ANY thing) and reform it through his arms at any time as he needs it. For example, he eats someone's gun, and he can reform it in his hand and it's fully functional. Being a Mercenary for hire, this ability naturally comes in handy.
The stories of Eat-Man follow Bolt Crank as he goes through various jobs, or sometimes back to an old acquaintance for a favor or to finish a job started a long time ago. Details on Bolt's origin have yet to become clear at this point, but hints are given in many spots, such as the end of the "Bye Bye Aimie" story in Manga Volume 3. There isn't a consistent plotline overall, most of the time each story is a one-shot, with sometimes two-parters. Some details from previous stories are carried over, and characters come back to make other appearances(such as Hard and Shadow) in later stories.
While I enjoy long, very detailed plot lines, for example Rurouni Kenshin's Kyoto storyline, Eat-Man is done with a style unlike any other. It's always interesting to see how Bolt completes his assignments, how he uses previously eaten items, and how he surprises everyone with his ability. Some have argued that this story is one trying to be a Trigun, and I heartily disagree with that. Trigun is an action/comedy in general, but Eat-Man doesn't try to be that. If it did, it wouldn't be nearly as interesting and unique as it is now. Akihito Yoshitomi has taken one VERY cool character and made him a diamond in the rough when it comes to manga. Not to mention that he has one of the coolest powers you could possibly imagine, and how he uses it is endlessly creative.
As of this writing, there are currently 11 Volumes of Eat-Man available, 11 was released like a week ago, so I don't have access to it yet. Anyway I hope you find this page helpful, I felt I should share these translations with fellow fans. Enjoy!
