Jinmen is an antagonist that appears in Devilman.
Jinmen is a large turtle demon who possesses a train driver and lures in a huge group of people, including akira's friend Sachiko, into his train and takes them into a cave where he eats them and all their faces appear on the back of his shell. Later on, Akira Fudo/Devilman confronts Jinmen and is horrified by Jinmen's shell as it contains all the souls of the innocent people he's eaten and is even more horrified and angered after seeing Sachiko's face at the back of his shell. Devilman tries to battle Jinmen but is hesitant to kill him because he doesn't want the people at the back of Jinmen's shell to die. Jinmen then flies towards akira in an attempt to crush while Sachiko tells akira not to worry about her dying so he can focus on killing Jinmen. Akira punches Jinmen in the back of his shell causing Sachiko to die, which angers akira to the point of him tearing off Jinmen's shell killing Jinmen instantly for good.
Jinmen is arguably one of the most depraved and disgusting villains in Devilman. He is a complete sadist who revels in the suffering of humans and enjoys tormenting them psychologically while keeping their faces on the back of his shell after eating them. He is also shown to be a necrophile in Devilman Grimoire where he has sex with Sachiko's lower torso after eating her upper half. After being killed in the original devilman manga, he is revived in Shin Violence Jack as he possesses a solder and adopts a spear as his weapon.
