Miles "Tails" Prower (Sonic Adventure 2)

Miles "Tails" Prower is fought in two boss battles in the Dark story of Sonic Adventure 2. He is fought while piloting his Tornado Cyclone mech. Both fights are done by Doctor Eggman, who pilots his Egg Walker.

Battle
The first fight with Tails takes place on a G.U.N carrier, after Eggman clears Weapons Bed. Tails will attack by using his Volkan Cannon when he faces Eggman, and using his Lock-On Missiles when Eggman is a distance away. Eggman must defeat him by shooting him with his weapons, while keeping his health up with rings surrounding the battlefield.

The second fight takes place in the central control room of the Space Colony ARK, after Eggman clears Cosmic Wall. This time, Tails uses his upgraded mech to fight Eggman. The fight is virtually the same, but with a few differences. In the center of the room, capsules will occasionally appear, that release a large explosion when destroyed. This can hurt both Tails and Eggman. Tails also has two super attacks that he uses as he takes damage. He can shoot multiple missiles that will home in on Eggman. He can also unleash a giant laser that will make Eggman take major damage. Eggman must be careful in this battle, because there are no rings or health capsules, so there is no way of replenishing his health.

Trivia

 * The fight against Tails in the Dark story is very similar to the fight against Eggman in the Hero story.
