Ken Ishikawa (June 28, 1948 November 15, 2006) was a manga artist active from the early 70s until his death in 2006. He was a great friend of the famous and influential {{Mangaka}} Creator/GoNagai, who he worked as an assistant for during the earlier years of his career. His most famous work by far is the mecha series ''Manga/GetterRobo'', though he himself isn't actually famous for it. Thanks to Ishikawa's willingness to credit Go Nagai for helping him out with the series during its early planning stages, ''Manga/GetterRobo'' is wrongly considered a Go Nagai work far more often (Dynamic Productions regularly crossing the series over with ''Anime/MazingerZ'' and and its sequels, not to mention their almost symbiotic appearances in the ''VideoGame/SuperRobotWars'' series does not help).

Ken Ishikawa is known for his distinctive art style and character designs, which usually involve lots of sketchy black lines, crazy spinning eyes and [[SlasherSmile insane grins]]. In addition to HumongousMecha, many of his manga were about ancient Japan and even in his sci-fi works, themes and philosophies taken from eastern spirituality are often present.

Ken Ishikawa sadly died early in November 2006, at the age of 58, though he's well remembered by many fans and animation studios.
