Not much is about other members of the band other than they all wear Sonic's iconic power sneakers. According Yuji Naka, the early idea of the Sound Test would involve Sonic breakdancing while his band played the music. However, several sketches featured in SEGA Megadrive/Genesis Collected Works artbook reveal all the band members had more relevant roles in the game, such as appearing in the Sega screen. One member from the band, Mach the Rabbit, is shown to be imprisoned along with other Animals in the capsule, as each of the band members had to be saved in each Zone of the game. The early idea for the game's ending would involve Sharps the Chicken saving Sonic from falling and sending him back to Green Hill Zone after destroying Dr. Eggman's escape plane.
