소닉 어드벤처
In later games, Tails had roles that require unique modes of play including "Sonic Adventure", where he appears as one of the six playable characters. His gameplay is based around standard platforming stages, but the goal of each stage is to get to the Chaos Emerald before Sonic, or to the missile dud in the final race against Eggman. In "Sonic Adventure 2", he is featured in third-person-shooting segments, seated in his "Cyclone" mech. These stages, along with Dr. Eggman's shooting levels in the same game, were very similar to the E-102 Gamma levels of "Sonic Adventure". In "Sonic Adventure", he was given a theme song "Believe In Myself", of which another version appeared in "Sonic Adventure 2".
