"Player One, your future is CANCELLED!"

Jimmy Neutron's robot dog, Goddard, got corrupted by Timmy Turner's video game while undergoing a system update. Now Goddard installed the data of the evil robot from the video game and became "the Decimator".

Though Timmy was able to defeat the Decimator Goddard, the Decimator was clever and well-prepared with a backup, saving the Decimator data inside Goddard but keeping the data offline until one of Jimmy's and Timmy's recent "activity" zapped Goddard, and somehow split Goddard into two, one of them having the Decimator data.

With the Decimator Goddard on the loose again, he starts attacking the people, cars, and anything that moves. Jimmy and Timmy, along with their friends, were unaware of the Decimator's existence as it attacked the city of Retroville, leaving the city in near chaos.

Based on Timmy Turner's video game, the Decimator follows the same rules as the game version. When he attacks and defeats a player, he grows. Only when you don't move, the Decimator doesn't attack you and will either look for another target, or enter Standby Mode until he detects any motion.
