While some may say that Superhuman Samurai was a second banana to the Power Rangers it was really a second fiddle to Ultraman (who came before Power Rangers/Sentai). SS was based on show from Japan called Grid Man which was produced by Tsuburaya Productions who in turn produced Ultraman.
The show focused on middle schooler Sam Collins who gets sucked into a computer and becomes Servo who defends cyberspace from computer monsters created by classmate Malcom Frink and brought to life by Kilokahn an evil cyber being. However Collins along with his friends who help him with his fight with the cyber monsters don't know that Malcolm is in league with Kilokahn. They see him as stuck up know it all. Malcolm as much as he hates Sam Collins does not know that Collins is Servo and neither does Kilokahn.
The Japanese counterpart does not last long and neither did this one, although it did produce a few more shows than Grid Man. It was fun to watch I admit, but at the time nothing could stop Mighty Morphin Power Rangers
