    "Amphibious robot proficient in underwater and sub-zero combat. Manipulates water, and can generate ice through its cooling ability."
    - Stage Select Description

    Mighty No. 2: Cryosphere, is a robot with water and ice based abilities, and the second member of the Mighty Numbers created by Dr. White.

    Appearance[]

    Cryosphere is the smallest of the Mighty Numbers and has an overall childlike frame. She is covered from head to toe in light and dark blue, diving suit like armor, complete with a large round helmet. Her helmet has a large red valve handle on the top, four eye-like yellow segments in parallel pairs on the front, and a yellow ball-shaped contraption resembling a pacifier at the mouth, and light blue headphone like protrusions at both sides emblazoned with her symbol. Her symbol is six lines extending in all directions from a single point, vaguely resembling a snowflake. She has the number "02" on the front of her torso in white. Her arms are asymmetrical, her right having a gray hose output valve for a hand and one white ring around the arm, and her left having a hose input valve for a hand, two white rings, and being nearly twice as long as the right.

    She has a large tank on her back which stores water, with a straw-like extension going into it from her back. It is transparent and made of two connected spheres, one large and one small, giving it the appearance of two connected bubbles. She has one white ring on both legs at the knees. Her feet resemble dark blue boots with yellow tips and black and yellow soles. She is 136cm/4ft 5.5 inches tall, and weighs 102kg/225lbs. It is heavily implied in the art book that her face is actually a mask, though what's under this mask has yet to be revealed.

    Synopsis[]

    Cryosphere, the second Mighty Number created by Dr. White, fought alongside her siblings in numerous battles within the Battle Colosseum. When a mysterious virus corrupted nearly every robot, Cryo fell under its influence and launched an assault on the Water Works Bureau, freezing the facility until it was forced to cease operations. In response, Dr. White dispatched Beck to stop her, though she taunted him playfully as he attempted to intervene. When Beck finally confronted her, she launched a freezing assault, but was ultimately defeated and restored to her senses.

    Once freed from the virus’s control, Cryo heads to the Military Base to locate Battalion and lends Beck her abilities by freezing enemies in the background. Later, after the Mighty Numbers were cured, she joins Beck, Dr. White, and her siblings in an assault on the Cherry Dynamics Robot Factory to shut down the production of malfunctioning robots. During the attack, she energetically berates Countershade for mocking her puns and gleefully celebrates when the area is cleared.

    Following Beck’s victory over Trinity in the Battle Colosseum, Cryo and the other Mighty Numbers are deployed to recover both Beck and Trinity from the collapsing structure.

    Personality[]

    Cryosphere is a mischievous, energetic robot who thrives on humor and pranks, always seeking amusement among her siblings. Her love for puns knows no bounds—she not only delivers ice-related wordplay at every opportunity but even suggests pun-filled quips for others, like Dynatron. Without an audience for her antics, she grows restless, and criticism of her jokes quickly sparks her temper.

    Despite her lively nature, Cryo's youthful demeanor contrasts sharply with her status as the second oldest Mighty Number. She holds her rank in high regard, occasionally reminding her younger siblings of her seniority when she feels disrespected. Though she sometimes acknowledges that her antics might be excessive, she remains inherently kind and amicable.

    Under the virus’s influence, Cryo’s playfulness twisted into malice. Her taunts became cruel, and her pranks took on a dangerous edge, making her far more unpredictable and threatening.

    Abilities[]

    Cryosphere stores water in the spherical tank on her back, harnessing it as a weapon in battle. She can unleash high-pressure streams from her right hand, powerful enough to propel herself into the air with a downward blast. When her tank runs dry, she swiftly reconnects her left arm to a water output valve for a rapid refill.

    Beyond her fluid strikes, Cryosphere manipulates water at reduced temperatures, firing flurries and ice projectiles that freeze targets on contact. Her own body is impervious to extreme cold, allowing her to encase herself in ice for devastating attacks—most notably, forming a spiky ball of ice and crashing down upon her enemies. Her primary weapon, Frozen Liquid, solidifies her command over both water and ice in combat.

    Other Appearances[]

    In Mighty Gunvolt Burst, Cryosphere returns as a boss with new icy tricks. She can forge a baseball bat from ice, sending frozen projectiles hurtling at high speed toward her opponent. Additionally, she encases herself in a swirling shield of ice balls, forcing the player to break through the barrier before dealing any damage (similar to Pump Man in Mega Man 10).

    Development[]

    After it was decided that Mighty No. 8 would be designed as a male instead of a female like it was initially planned, KIMOKIMO decided that the water and ice theme of Mighty No. 2 would be more fitting for a female design. KIMOKIMO based Cryosphere's final design off of old British diving suits, in contrast with Beck's astronaut spacesuit inspired design. She was devised to be the adorable mascot of the Mighty Numbers and her baby-like proportions, pacifier shaped mouth contraption, water-bubble shaped carry-on tank and bulbous helmet are all meant to give her a suitably cute appearance. Her left and right hands were designed as water input and output valves, respectively, to both address the problem of how her water tank was meant to refill and give her an interesting, asymmetrical appearance. In early stages, Cryosphere was designed with more female characteristics in mind, such as a faucet on top of her head resembling a ponytail, but the faucet was later moved to her right hand. Her earliest design sketch was more obviously feminine, resembling a female figure skater, but began to change after headphone-like protrusions were made a key design element of all of the Mighty Numbers. It was also changed in response to a narrowing down of the Battle Colosseum's role in the game from a sports event to a specifically combat oriented one, leading to shift of focus from athlete inspired designs to more battle-ready, powerful ones.

    Trivia[]

    • It is possible that the first six Mighty Numbers are based on Mega Man bosses, and Cryosphere is partly based on Ice Man from the Mega Man series. She is also based on Splash Woman from the same series because of her gender and her water theme, as well as Bubble Man for being based on diving suits and Pump Man for being based on ways of working water.
    • Cryosphere's large, circular water reservoir bears some similarity to Mega Man 8's Aqua Man.
    • According to KIMOKIMO, Cryosphere has a more human-like face underneath her mask, It is currently unknown if this true face will be shown.
    • A scrapped piece of concept art depicted Cryo as a figure-skater. This concept would later be reused for Luminous Avenger iX 2, as the main inspiration for Hail.
    • For unknown reasons in the GDC video, Cryosphere uses masculine pronouns.
    • Much like Countershade and his rifle, Cryosphere can morph her hoses into hands.
