Acid Ace

Acid Ace is the Wave Change form of Shane Hunter (Shidō Akatsuki in the Japanese version) 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. Due to the nature of his various attacks, he is capable of attacking the weakness of all non-Finalized Noise Changes, barring Burai Noise(which has no element). Including the Battle Cards, Acid Ace has the biggest moveset in the Star Force Universe, and in the entire Battle Network/Star Force universe, is only second to Bass.EXE. Known attacks are:
 * Ground Wave : Similar to its Battle Card, which travels across the ground and changes rows to move towards the player.
 * Giza Wheel : Similar to its Battle Card, which travels down the column before curving at the player. It can be deflected by attacking the wheel.
 * Machine Flame : Similar to its Battle Card, which hits all panels down the column.
 * Wide Wave : Similar to its Battle Card, which travels down three adjacent columns.
 * Stealth Laser : Similar to its Battle Card, which fires several Invis-piercing shots down the column.
 * Squall : Similar to its Battle Card, which hits multiple times on one panel, removing Barriers and Auras.
 * Lock-On Sword : Acid Ace locks onto the player's current position, then moves to that panel and slashes it, cracking the panel. This attack cannot be blocked. Later versions have him slash two times.
 * Wing Blade : Acid Ace charges down two adjacent rows. This attack cannot be blocked.
 * Acid Laser : Acid Ace stands on the central column, and fires a laser down all three columns. This attack cannot be dodged.

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. Also two other forms they are Acid Ace R and BB which Acid ace R is fought in the the secret server.
