As a little kid way back in the 90's, I saw Guyver for the first time on Scifi channel among other animes, ( Ghostin the Shell, Akira, Robotech, Fist of the Northstar, ect.)
The episode I saw was Guyver I killing Sho's dad who turned into Enzyme II, that actually scared me...
It left me with a fear for bloody anime and characters with robotic voices. XD
Some years went by, and the Guyver OVA series aired on TV, every saterday. and the very first episode that's I saw, was Guyver I fighting the Hyper Zoanoid Team Five.
It was still be a scary, and my parents changed the channel everytime I was watching it. XD
My English was very bad, but I could read the dutch subtitles a bit, so the story around the Guyver was kind of hard to follow.
Afterwards, I rented the avilable VHS tapes at the local video store and watched some of the episodes, until 2005/2006, I heard of the remake and decided to watch the older ones first.
when I got all VHS taped from a friend, I watched them back to back, marking my first time watching the complete series.
