I was checking out this bizarre live action Japanese Spiderman from 1978 yesterday. After watching a full episode I think I'm well versed in everything they did to our beloved Spiderman.
Toei Spiderman was born by an injection from a Spider Bracelet which was handed down from his father who was a "Spider Warrior". Spiderman's suit comes from his bracelet somehow, as does his webbing (which is actually rope) and his giant mech. That's right, Spiderman has a fucking Mech! Not only that but Spiderman has a racecar which can fly and shoot "Genie Missiles". This is basically Spiderman and Power Rangers merged into an unholy union.
