Rouge the Bat (Sonic Adventure 2)

Rouge the Bat is fought as a boss in the Hero story of Sonic Adventure 2. She is fought by Knuckles the Echidna, after clearing Meteor Herd.

Battle
The battle takes place in the large tower seen in the center of Meteor Herd. Rouge will attack either through her Kick Attack, or by gliding and using the Screw Kick. Knuckles must attack her when she lets her guard down. Eventually, the floor below the two will open, sending them into the air. The fight will continue on the sides of the tower when this happens, until the floor closes again. As Rouge takes damage, she will begin to use two special moves depending on Knuckles' distance from Rouge. If he is a short distance away, then Rouge will use her special move, the Hip Drop, to stun Knuckles. If Knuckles is very far distance away, then Rouge will use her super move, the Black Wave. Four hits are required to defeat Rouge.

Trivia

 * The fight against Rouge in the Hero story is very similar to the fight against Knuckles in the Dark story.
