Toshio Tenma

People says that Rockman is based in Casshan, however they forget that Rush (the dog sidekick) only appeared in Rockman 3. Which still imply that Rockman draws inspiration in Tetsuwan Atom. Also, Yatterman had a dog like mecha with a more cartoon look like Rush. The character Hakaider from Jinzō Ningen Kikaider used to wristle before making an appearence which may be part of the inspiration for Blues.
