Thunderbolt the Chinchilla

Thunderbolt is a character that appears in the Sonic the Hedgehog comic series and its spin-off comic series published by Archie Comics. In the Post-Super Genesis Wave timeline, she is an anthropomorphic animal and the Egg Boss of a division of the Egg Army stationed in the Rainforest on Sonic's World.

Appearance
Thunderbolt is an anthropomorphic animal of an unspecified species. She has a light and short muzzle with long ears, and has wide maniacal eyes and a similar smile. She also has long tufted fur around her neck, though it is unknown if it is her own or a part of her attire. The left side of her muzzle appears cybernized, with a cable attached to it.

History
During the Shattered World Crisis, Thunderbolt and her forces managed to recover a Chaos Emerald. As she was about to report to Dr. Eggman of their find, the doctor contacted her. Thunderbolt promised to deliver the Emerald soon, but Eggman ordered her to keep it and use it as bait for the Knothole Freedom Fighters, a plan she took a liking to.

Personality
Thunderbolt is seemingly twisted and sadistic as she openly likes Eggman's way of thinking.
