Proper Name: 安孫子 素雄 (Abiko Motoo)

Originally established as part of the legendary mangaka duo Fujiko Fujio with Hiroshi Fujimoto, their partnership ended in the late 80's at which point their works were credited to the individual members of the duo who actually made them. There were actually relatively few works that the two had worked collaboratively on and while Fujimoto often appeared in elementary school manga magazines, Abiko was much more active in the mainstream shonen magazines with a major franchise in many of them. He also created the most famous seinen serialization originally published under the joint pen-name, Warau Salesman (which was called Kuroi Salesman at the time of original publication).
