If we're talking greatest animes, I mean one name that's gotta come up is Rugrats. Ya gotta go with Rugrats.
Ahead of it's time in animation, storytelling and jamz. Easily better than Stu Pickles alone basically encapsulates everything that's great about anime's like Cowboy Bebop.
There's also a japanese character, how more anime can you get?
Rugrats was the shit.
But only the baby phase.
