plarfman:Actually, INFRA-MAN was based more on MASKED (KAMEN) RIDER, the other classic Japanese superhero besides ULTRAMAN.  MASKED RIDER gave birth to the Henshin Hero genre (which also spawned the Super Sentai series, which POWER RANGERS hacked from), and if it weren't for him, INFRA-MAN wouldn't have existed!  :)THE SUPER INFRAMAN is still my favorite superhero movie ever, next to THE INCREDIBLES!  ;)
