Avatar series (it was Korea,n and Japanese made for one season)

Code Lyoko (French made. This was my jam as a child. Watched it religiously. Can't really find this series anywhere anymore and nobody really remembers it)

Xiaolin Showdown (stupid show from Canada, but it was so well animated and had a plot)

Lot of the old american cartoons

Classic Cartoon Network shows from the 1990s

These are some of the main ones, I have a lot more but these just some.
