Cryosphere is a boss character appearing in Mighty Gunvolt Burst.
Official Site Description
Alias: Cryo. Uses her ice abilities in different ways to restrict her target's movement while attacking unhindered. Her flexible attacks use ice shaped into many different forms, so her foes must stay on their toes.
The floor of Cryosphere's room is covered in ice, hindering the player's movement.
|A ring of 6 ice balls is summoned and rotates around Cryosphere, repelling bullets and freezing the player on contact. 8 ice balls in Hard Mode.|
|Cryosphere summons a bat and begins launching her ice balls at the player at varying heights. These can be shot and destroyed mid-air, and do not freeze the player. Their rate of fire is higher on Hard Mode.|
|Cryosphere jumps into the air above the player, summons an ice hammer, and slams into the ground with it.|
|Cryosphere hovers in the center of the arena and expends her ice balls to launch high pressure water jets, which freeze the player on contact. She may fire them one at a time, two at a time, or all at once.|
Cryosphere's water jet skill bears a resemblance to Milas' attack Hydro Zapper, and her stage features water torrents that send the player upwards like in The Sewers. Coinciding with this, Milas' pixel sticker is a reward for completing the stage.
