Ben and Zane were so excited to try out for the legendary superhero group, the Teen Titans. They didn't have any powers, but they could go from silly to serious on a dime, and had control over their own emotions. Unfortunately, the Titans weren't as mellow, and attacked the Cartoncasters, thinking they were supervillains, what with the existing in their city. Since it was the first few minutes of the episode, Ben and Zane actually managed to overpower them. They left before the inevitable power-of-friendship dialogue. It was a formulaic, transparent visit, but man was it cool.
