Duck tales, first season of pokemon. The second pokemon movie was the best. I also like Tailspin. There's a couple more but I can remember right now.
<grumpy old man> You kids with your fancy TVs! Back in our day we had to act out cartoons ourselves! </grumpy old man> j/k. Can't tell you much about childhood cartoons because I grew up in Ukraine, so you wouldn't know of any of them. By the time I came to the US back in '92 at the ripe age of 16, I already outgrew the "cartoons" phase. (Comedy Central's [adult swim] kinda brought me back.) I can tell you what my 3-year-old brother was watching at the time though. TMNT were in their peak, Batman and X-Men animated series' just started airing on Fox, Power Rangers were just a twinkle in Haim Saban's eye, and Pokemon was still 6 years away.
You don't really get the internet, do you? The (original) Transformers, Visionaries, Legend of Prince Valiant, Centurions, M.A.S.K., TMNT, Ulysses, Danger Mouse, Bat Fink. I think I can honestly say most of my sense of right and wrong was guided by Optimus Prime. Oh and Pokemon? WTF? How young are you guys? How old am I? Pokemon didn't fucking exist when I was young. Half the TVs around were still black and white FFS! They were powered by coal and flywheels.
