Acid Ace

Acid Ace is the Wave Change form of Shidō Akatsuki and Acid. Using the Ace Program, they are able to Wave Change to form Acid Ace, and are registered under Project TC as No. 001. Acid Ace looks somewhat like a Gundam robot claded with sirens almost everywhere suggesting a symbol of enforcement of law.

In the game, Acid Ace is a unique boss, being able to use different Battle Card attacks in succession, in addition to his own attacks. Known attacks are:
 * Ground Wave Battle Card
 * Giza Wheel Battle Card
 * Machine Flame Battle Card
 * Wide Wave Battle Card
 * Stealth Laser Battle Card
 * Squall Battle Card
 * Lock-On Sword
 * Wing Blade

He is fought three times in the story - once where he cannot be damaged and the player has to survive a few turns, a second time normally, and third as Acid Ace B, when corrupted by noise.
