Red Buster. Male. Partnered with Cheeda Nick. As the leader of the Go-Busters, he is a young man who harbors passion within his quiet demeanor. He lost his parents in the incident 13 years ago and lives with his older sister. He is a perfectionist in everything he does. He is a multi-talented individual with both great skills and intelligence. His sense of duty is outstanding, and he is so calm that he can appear cold. He is a straight-talker who says what is on his mind without sugarcoating it, but he is fundamentally kind and, on rare occasions, can pull light pranks or make jokes. His weakness is chickens. Whether it is a real chicken or just a photo, seeing one causes his body to freeze for at least 5 minutes; he even freezes up just by hearing words that remind him of chickens.

Blue Buster. Male. Possessing a kind and warm personality, he is the oldest member of the group. He is a hardworking warrior who never skips training. Like Jackie, he is calm, collected, and calculating. At 28 years old, there is a significant age gap between him and Jackie (20) and Ravi (16). His partner is Gorisaki Banana. His weakness is the heat emitted from both arms. If he uses too much power, he goes into a thermal runaway state. Because of this, he frequently uses cold packs to cool his hands.

Yellow Buster. Female. Partnered with Usada Lettuce. Being the youngest (16), she often shows an immature side and is quite emotionally fragile. Furthermore, she fights Vaglass without having entered high school, and her education consists entirely of private tutoring from her partner. As the sole female member, she is a warrior with a strong-willed and confident personality. Due to the influence of the vaccine program, she boasts excellent jumping ability and powerful kicks, but her weakness is that her energy drops rapidly if she doesn't constantly consume sweets.

Beat Buster. Male. A genius engineer from the Energy Management Center, capable of creating Buddyloids on his own. He was transported to sub-space during the incident 13 years ago but reappeared in the year 2012 AD looking exactly as he did then. It is revealed he has known Ryu for a long time, and Ryu is said to have respected him as a genius engineer. His weakness is that he cannot transform if he is separated from Beet J. Stag by more than a certain distance.

Stag Buster. A Buddyloid created by Jin himself. Developed as Jin's backup system, he is an extremely important Buddyloid responsible for Jin's transformation and the transport of avatars and Buster Machines. Consequently, if anything goes wrong with him, Jin faces the fatal weakness of being unable to perform almost any activities.
