For those of us that grew up in the late '90's-early 2000's, these are some of the cartoons we remember the most, and the ones we wish had never ended.
1. Dragon TalesGiphy
2. Kim PossibleGiphy
3. Danny PhantomGiphy
4. My Life As A Teenage RobotGiphy
5. Spongebob Squarepants
But the older episodes before about 2010.
6. Foster's Home for Imaginary FriendsGiphy
7. Teen TitansGiphy
Teen Titans Go! is a poor replacement for the original.
