I'm surprise someone else besides me has seen and enjoy Gencoyber. The anime is a total mess, but I enjoy it for the ultra violent trashy factor to it. I seen that anime many times and yet I still don't understand the anime. Probably one of the biggest guilty pleasures. Not to mention the soundtrack for the anime is awesome.

Adding to my previous post from how many long time ago, allow me to add these following Crayon Shinchan and Gintama.
Saint Seiya
Dragon Ball Z
SLAM DUNK
Gag Manga Biyori
Kinnikuman II
Guruguru
Inazuma Eleven
Tiger Mask W
