Sticks the Badger, "Buster"

Buster, also known as Cluster Bot, is a character that appears in the Sonic Boom television series. It is a Slime Bot created by Dr. Eggman as a sleeper agent to be implemented amongst the ranks of Team Sonic. It was briefly adopted by Sticks the Badger as her pet, who managed to turn him against his creator.


Buster and pink background

Buster's default appearance.

Buster is a head-sized, dog-shaped robot who outwardly appears poorly made. He has a pink and yellow lunchbox for body, four suction cups for feet and a winding handle for tail. He also possesses regular door handles for ears, a burn-out bulb for nose and green eyes with slightly darker green irises.

When transformed, Buster grows to almost twice the size of Eggman's height, his feet retract into his body and are replaced by eight tentacles coming out of his sides, and his eyes turn bright red (while he is under Eggman's influence).


TV series

Season one

Created by Dr. Eggman, Buster was meant to be used against Team Sonic when they sought a pet for Sticks. Left to be discovered by Sticks, she took an instant liking to him and adopted him, giving him the name "Buster", although her friends were repulsed by him. Over the next week, Buster would mess up Team Sonic's daily lives, eventually ruined their attempt to stop a robbery made by Orbot and Cubot. When Team Sonic failed to make Sticks give up Buster, Eggman visited and gave Buster a mechanical bone, turning him into a monster. One by one, Buster caught Team Sonic until Sticks reestablished his loyalty to her, making him get rid of Eggman. Returning to normal by regurgitating Eggman's bone, Buster was sent away by Sticks since he was too dangerous.[1]


Buster has all the behavioral patterns of a real dog. He is energetic and affectionate, though this comes off as annoying to other people. He is as well incredible loyal to Sticks, so much that he overcame Eggman's programming and left Sticks to wander the world alone upon her orders despite his attachment to her.[1]

Powers and abilities

In his normal form, Buster does not have any special powers or ability, However, he can constantly excrete green slime as saliva and perspiration.[1]

Buster transformed

Buster when transformed.

After transforming from eating Eggman's nanotech bone, Buster grows several times his own size and gains drastically increased power and speed, so much that Sonic could not defeat him alone. In his transformed state, Buster gains several flexible and powerful tentacles which can regenerate should they be cut off. If the nanotech bone leaves Buster's body though, he reverts back to normal.[1]

As an Eggman robot, Buster is also able to receive power remotely from Eggman's lair.[2]


Being an Eggman robot, Buster relies on Eggman's lair to provide him with power. As such, should the lair run out of power, then he will too.[2]





  • Despite being a robot, Buster is able to eat both organic and inorganic food.
  • Buster bears a resemblance to Goddard from the Jimmy Neutron series.
    • Similarly, the green slime may be a reference to Nickelodeon.
