Cartoons in the '90s came with an edge, and these must-watch shows -- from boundary-pushing adult programs to influential anime -- are the cream of the crop.

As the decade in which cel animation reached its arguable peak of large-scale sophistication before the CGI takeover of the 2000s, the '90s are nothing short of a platinum era for television cartoons.
