Chucky was born to Cleaver Beaver and his wife. In his parents' care, Chucky and his siblings were overwhelmingly hard for their parents to control, forcing them near a nervous breakdown. Many attempted to control Bucky, Becky and Chucky, but all failed.
After the destruction of Beaverville, caused by Dr. Robotnik, was prevented by Sonic, Tails promised that he and Sonic would babysit Chucky, Becky and Bucky while their father prepared a party in Sonic's honor, on the grounds that Sonic loved "babes" (which Sonic meant as in girls). At first, Chucky, Becky and Bucky slept when the duo came, but they quickly awoke and drove Sonic and Tails crazy as they attempted to take care of them. Eventually, Sonic took the trio of baby beavers out for a walk, but they got kidnapped by Scratch and Grounder for the purpose of luring Sonic into a trap. While transporting them onboard a blimp however, Chucky, Becky and Bucky messed around with Scratch and Grounder and took control of the blimp, making it crash into Dr. Robotnik's fortress. From there, the babies messed around with Robotnik by playing with his Reversible Melto Freezo Ray before the doctor finally detained them.
As planned, Robotnik managed to trap Sonic and Tails in an inescapable pit using Chucky, Bucky and Bucky as bait. When Robotnik then when to try destroying Beaverville again, Chucky and his siblings broke out of their cage to free Sonic and succeeded by using Robotnik's Melto Freezo Ray. Unwilling to leave the babies alone, Sonic and Tails then took them with them to stop Robotnik despite Sonic's dismay. When they found Robotnik and his drilling machine which he planned to flood Beaverville with, Sonic was incapacitated by an electric shock, making Chucky, Becky and Bucky step up to his aid. The baby beavers snuck into Robotnik's machine where they drove Robotnik, Scratch and Grounder to surrender with their antics, saving the town. Soon after, Sonic got Chucky, Becky and Bucky back home just before their father returned. However, Chucky, Becky and Bucky were quickly placed in Sonic's care again for the weekend by their father so he and his wife could get a break.
Matching his siblings, Chucky is energetic, playful and extremely mischievous which tends to get on the nerve of other people. After spending time with Sonic, he came to pick up some of his behavior which included his catchphrases and his go-to attitude.
