Team Rose features Amy Rose, Big the Cat, and Cream, with Espio the Chameleon, Vector the Crocodile, and Charmy the Bee rounding out Team Chaotix. Team Sonic consists of Tails, Knuckles, and the Blue Blur himself, while Team Dark is represented by Shadow, Omega, and Rouge. A total of four teams are available, all consisting of members from previous Sonic the Hedgehog games, ranging from the 1991 original to 2003's Sonic Advance 2 on Game Boy Advance. Unlike Sonic Adventure and previous Sonic games, however, players control a three-character team throughout the colorful worlds. Like the Sonic Adventure series, the levels are depicted in 3D from a perspective behind the character. Sonic Heroes marks the first significant change in Sega's long-running franchise since 1999's Sonic Adventure on Dreamcast.
