Metallic Ninja Gamesh

Metallic Ninja Gamesh (鉄忍 ガメッシュ): The boss of the Metallic Ninja Clan, a gang from Germany which plots to rule the world by using science for crime. His weapons includes two swords, a sickle and chain that channels electricity, and a boomerang knife which he stores inside his right eyepatch. His Magnetic Storm Metallic Ninja Art (鉄忍法磁気嵐) causes him to shoot a red laser from his armor and cause a magnetic storm, while his Dark Hiding Metallic Ninja Art (鉄忍法闇隠れ) allows him to hide in the shadow of his opponent. In Episode 23, he kidnaps three scientists (Dr. Smith, Dr. Brown, and Dr. Schmidt) with the help of the Sorcerers Clan, but his plot is foiled as a result of a quarrel with the Sorcerers Clan and he is ultimately defeated by Jiraiya. In Episode 40, he is rebuilt as "Gamesh 002" and cooperates with Demost to hunt down Jiraiya, but ends up being defeated by Mafuuba.
