Male. Purple eyes. Red echidna mobian. Wears white gloves with two spikes and sneakers with white and red patterns. He is fast, though not as fast as Sonic.

Female. Green eyes. Pink hedgehog mobian. Wears white gloves and knee-high sneakers with vertical white and red stripes. She wears a red headband and a red dress that reaches above her knees. She has a one-sided crush on Sonic (she gets hurt when Sonic doesn't notice her, but her strong mental fortitude allows her to keep pursuing him). She is quite fast. She is highly skilled with her Piko Piko Hammer (a very large hammer). While she may appear weak, her strength is comparable to Knuckles'. She loves desserts, especially strawberry shortcake. She serves as the melee and healer for Team Sonic. She is the only one in Team Sonic who wears clothes (red dress and red headband).

Male. Red eyes. Black hedgehog mobian. Wears Jet Shoes and has white fur on his chest. He has red stripes on his black fur and is Sonic's fated rival. Like Sonic, he is fast and possesses immense combat power. Using the power of the Chaos Emeralds, he can teleport with Chaos Control and summon spears with Chaos Spear. He is more proficient with firearms, weapons, and vehicles (motorcycles) than humans are. He looks similar to Sonic. He has a tsundere-like personality. While not an official member of Team Sonic, he stays near them and fights alongside them, and the team members don't mind. Does not wear clothes. He likes coffee and even enjoys chewing on raw coffee beans.
