Pokemon. (when it was good)
Case closed. (a.k.a Detective Conan)
Yu-Gi-Oh (also played the card game with other kids)
Beyblade (played with my brother, had an accident with my eye)
Powerpuff Girls (don't judge me)
and last but not least, Digimon. (loved the fuck out of that anime)
Most of my childhood I spent watching shows on Toonami and Cartoon Network. I feel bad for the kids growing up with shitty cartoons nowadays..
