He is close with all team members and has a wide network of contacts. He is especially close with Amy and Tails. While in the containment room, he is playful and talks with his friends, but he becomes expressionless and cold during missions. Height 100cm, weight 35kg.

Male. Purple eyes. Red echidna beastman. Wears white gloves with two spikes and sneakers with black accents. He is fast, though not as fast as Sonic.

She is also fast (though not as fast as Sonic). She is skilled with the Piko Piko Hammer (a very large hammer). She serves as the melee and healer for Organization Team Sonic. She is the best communicator among the team members. Height 90cm, weight is said to be a secret (despite her lean build).

Male. Red eyes. Black hedgehog beastman. Wears white Jet Shoes and has white fur on his chest. He has red stripes on his black fur and is Sonic's fated rival (but since they are teammates, he cannot attack him). Like Sonic, he is fast and has very high combat power. He also looks similar to Sonic. He is a bit of a tsundere. He wears a white dress shirt, a black leather jacket, and long white pants. He is the attacker and supporter in Organization Team Sonic. While he seems like he wouldn't talk much with the team, he actually communicates quite well (especially with Tails and Amy). Height 100cm, weight 35kg (same as Sonic). Large frame but lean.
