I totally agree there is nothing to watch when I am bored or if I really want to see something from the shows I watched as a kid that I haven't seen in a while. The only somewhat intelligent villain that actually has okay plans that I can actually remember is the guy from Chip 'n Dale. The sad thing is that I can't remember his name, only the voice.
Idk, the only thing I know is that ONE Chip 'n Dale villain was a good cartoon villain, but there have been a few other formidable opponents from the Aladdin tv show. I hate not remembering these people, but the funny thing is that I recognized one when I saw him without even knowing the name.
