Suitable Opponent is a boss theme from Sonic Adventure 2. It plays during several of the character vs. character battles: both fights between Tails and Eggman, and the fight between Knuckles and Rouge. However, both fights between Sonic and Shadow have their own boss themes ("Shut Up Faker!" and "For True Story" respectively), probably because they are the game's main characters.
It also plays as an event theme in the extended cutscene before the second fight between Tails and Eggman, and when Rouge tells Sonic and Knuckles that the ARK is on a crash-course with Earth.
