FusionFall Character Biography #2|Dexter From Dexters Laboratory.

 Dexter is the younger (but more intelligent) brother of Dee Dee. He is a boy genius and is fully devoted to science, but he is also very arrogant and takes great pride in his intelligence. In the series, he has a lab behind his bookshelf, where he performs experiments and creates inventions, which usually leads to trouble for him and his surroundings. His lab is usually devastated by his sister Dee Dee who just wants to play with his inventions.

 Dexter inadvertently created the chupacabra, but this causes some confusion concerning the chupacabra in The Secret Saturdays and in The Grim Adventure Of Billy And Mandy.


Prior to FusionFall, Dexter has asserted himself as a world famous genius and inventor, and can sometimes seem like the leader in the fight against Fuse. Before he hit his teenage years, Dexter founded his company, DexLabs, and became more and more withdrawn therefore after. Computress, Dexter's robotic assistant became his only companion.

 The Future
 At an unspecified time, the Hero has enlisted in a DexLabs time travel project. Before Dexter can program a destination into the machine, Dee Dee messes up the project (with her most famous line, "Ooooh! What does this button do?"), and sends the Hero into the far future where Planet Fusion's invasion has almost completely overtaken Earth. Dexter appears briefly and helps the Hero fight off his/her first Fusion, Fusion Buttercup. He is seen earlier helping Numbuh One, but disappears after Tech Square is devoured by the Fusion Invasion, signifying that he was lost after Tech Square fell. Shortly after on, a holographic message comes from Dexter for the characters to help the Hero back to the past.

The Past
  Dexter can be found in Tech Square in front of DexLabs, alongside Computress. He has constructed a home for his parents on top of his company building in order to protect them after Fusion Spawns started appearing around his old house in Genius Grove.
