Dark Finish

The Dark Finish is a move that appears in Sonic Adventure 2: Battle. It is a special attack that revolves around the Dark Chao firing a super-charged laser out of his Dark Chao Walker.

Description
Although despite the move being the equivalent of Dr. Eggman's and Tails' Power Laser move, and the Chao Walker's Zap Laser, the Dark Finish is mostly a blue and white laser surrounded by blue circles, while there are some yellow circular energies inside the laser.

In gameplay, the Dark Finish marks the Dark Chao Walker's most powerful attack, being a thick dark laser that emits from the front of the machine that can be manoeuvred to a certain degree and can deal significant damage to the opponent. To use it in gameplay, press the Action button while in possession of sixty Rings. This attack only appears in the Multiplayer mode of the game, since the Dark Chao Walker only appears in that mode.

Trivia

 * Though the attack is supposed to be more powerful than the Zap Laser, the Dark Finish is thinner than the Zap Laser.
