Shungushin Genji

Shungunshin Genji is a Robo Oni from the World of Captorman. 

While Alive
During life, Shungunshin Genji was a very rich and young man in feudal Japan. He eventually became obsessed with the seven elemental jewels, specifically the gem of Gold. This attracted the attention of the samurai Janga, who took him in and trained him in the art of illusions. He eventually used this power to go after the Gold Captor Ninja, killing her and stealing her gem. He was eventually killed by the Water Captor Ninja when he tried to steal his gem.

Revival
Genji was revived in the modern day by KiShogun Jaguar, this time as a robotic demon. His illusion powers were amplified in this form, allowing him to make unlimited copies of Shungu soldiers. He fought against Captorman, but was continuously foiled by him. He was eventually killed by Captorwoman and trapped inside of a stone.

In the RPverse
Genji appeared in the RPverse to kill the Kamen Riders. He didn't know what a Kamen Rider was, so he began killing innocent civilians. He was eventually confronted by Decade, OOO, and Inspector Cypher. He was beaten by the three, and ran away from the battle.
