Description
Fatman operates as a cyborg soldier within a rogue US military division—alternately called the Machiner Platoon or U.S. Machine Corps—which pursues global dominance by weaponizing ancient OOPArts. His codename explicitly references the "Fat Man" atomic bomb, and his real name is undisclosed.
His background diverges across adaptations. In the 1998 animated film, he commanded Yu Ominae in Project COSMOS, a covert initiative training child soldiers. Near-fatal injuries sustained during Yu’s rebellion against COSMOS necessitated his cybernetic reconstruction. The 2022 ONA adaptation reframes him as Yu’s direct combat instructor within COSMOS, heightening their personal conflict. Post-augmentation, featuring Orihalcon armor plating and a prosthetic right arm, he became a key operative for the U.S. Machine Corps.
Driven by vengeance against Yu, he abducted and murdered several of Yu’s associates to lure him to Turkey’s Mount Ararat Noah’s Ark excavation site. Each victim bore the message "NOAH WILL BE YOUR GRAVE".
Physically, Fatman’s massive cybernetics include Orihalcon armor plating—resistant to firearms but vulnerable to artillery—and a replaceable right arm configured as a Vulcan gatling gun fed by a dorsal drum barrel. These augmentations confer immense strength but drastically reduce his mobility.
His demise varies: the manga depicts Jean Jacquemonde killing him with a Franchi SPAS-12 shotgun blast to the face during the Turkish battle. The 1998 film shows Yu Ominae slaying him in a rage. The 2022 ONA adaptation features Yu severing his cybernetic hand and destroying him with a jeep-mounted 30mm cannon round to his exposed armor.
