Ice

Ice is a Wizard of, Suzuka, a good friend of Sonia Sky. Ice is somewhat a snob and gets jealous easily. After MegaMan defeats Taurus Fire in the third game, the director of Sonia's drama serial enlists MegaMan to replace Suzuka. Ice is not happy with this, and Jack takes the opportunity by giving Ice a Noised card, allowing her to have a chance to take revenge. Driven by jealous rage Ice accepts it and mutates into the fairy-like mutant Dia Iceburn, and proceeds to attack the studio and attempt to stop Sonia's last live-stage performance.

Dia Iceburn is the third boss fought in the game's plot. She always has two ice crystals alongside her, and while they can be destroyed by breaking attacks, they often obstruct the player. Known attacks are:
 * Iceburn's crystals slide towards the player.
 * Iceburn sends the crystals across the player's current row. This attack must be blocked.
 * Iceburn summons a strong wind that covers most of the area ahead of the player, turning affected panels into ice panels.
 * Break Icehammer: Iceburn attacks the player's current position with a hammer.
