That show died when Cartoon Network thought "How can we make this stupid and child friendly? Let's make every episode completely random and cheapen the art style!"
I tell people the same thing every time. "They finished their quests and job. What else you want them to do?"
I mean.. I didn't watch it faithfully but I know it eventually ended and they deformed, living their own lives.
Although my favorite episode is the saddest one for me. The Future Titans, such a lonely cyborg.
