Ultimate Cartoon Network

Ultimate Cartoon Network is the Cartoon Network universe revamped with anime-style designs and frequent crossover team-ups! (Along with Hanna-Barbera, Looney Tunes, and possibly DC comics) In this universe, anthromorphic talking animals (Scooby-Doo, I.M. Weasel, Cow & Chicken, etc) have been around for a long time, so the world has become acustomed to them. (Like in Ted)

Ultimate Kids Next Door
This version goes deeper into the origins of KND Sector V and many of their enemies. It also shows more about the KND's connections with the world. The general public doubts their existance, but the few adults who do believe consider them terrorists. Thankfully their identities are unknown. Their portrayal is basically Men in Black meets Leverage.

Ultimate Powerpuff Girls
The girls are now 10 years old, and their history is mostly intact. They have started to become more independent from one another, but still love each other nonetheless. They have also worked with several other superheroes around the globe. They're friends with the Kids Next Door, but have been asked to keep their encounters secret for the sake of the organization's security, as well as the girls' public image.

Ultimate Dexter
Unlike the other titles, Dexter's series focusses on his adventures in scientific exploration, rather than battling evil. This series also deconstructs his genius: he was self-aware while developing in his mother's womb, he paid for his lab by pattenting some of his minor inventions under an alias, etc. Dexter now has a friendly rivalry with Numbuh 2, both attempting to out-genius each other. He's also fallen in love with Blossom (she secretly returns his feelings). Dexter also frequently aids Global Security (from Dial M for Monkey) when they need his genius.

Ultimate Ben 10
This Ben is still 10 years old. Ben's backstory and world remains mostly unchanged. However, this version has many more friends in the other titles. The other heroes generally consider him irritating, but view him as a friend.

Invasion
An adaption of 2007's "Cartoon Network: Invaded" event, while taking some influence from Marvel's "Secret Invasion"

vs Nickelodeon
Two universes collide in an epic clash while a strange being called Master Control (the remote from Cartoon Network: Punch Time Explosion) attempts to eradicate all of reality
