Cancelled Season 4
There was supposed to be a season four (which would've also been the final season), but DNA Productions went out of business due to the failure of The Ant Bully before season four could be produced. Cancelling the series was a big loss for the company. There are four scripts finalized, but they are in secret until further notice.
The fourth season was going to be darker and more serious than the previous ones. Many proposed things in the season were:
- An overarching story about the gang starting middle school.
- The premiere episode would've featured Jimmy and the rest of his class teaming up to stop Evil Jimmy and the rest of their evil clones, who have escaped from the Dark Matter Dimension during a class field trip to an asteroid.
- An episode about Cindy, Libby and Betty getting stuck in Jimmy's lab.
- Jimmy and Cindy permanently ending their fighting and rivalry.
- New and more dangerous villains.
- Jimmy's friends getting enemies of their own.
- Nick becoming part of the main cast again.
- Brittany becoming a main character.
- The series finale would've been about all the members of Team Neutron fighting the now-rebuilt League of Villains.
