Appearance

Before its transformation into a Mysterious Being, Shiverhuahua was a normal lapdog.

Personality
Before becoming a monster, Shiverhuahua seemed to be a normal friendly lapdog.

Being formerly a lapdog causes Shiverhuahua to rampage in fear and worry when going outside. After becoming a monster, it attacks anyone with hostility against it, considering them to be its enemies and claiming that killing them will bring peace.

History
Shiverhuahua used to be a normal lapdog. It was monsterized due to turning distortedly wild from extreme miniaturization.

Neo Heroes Introduction Arc
Shiverhuahua is purposely released from its imprisonment to fight Mad Devil Yankee, a B-Class hero. Its fight is a gamble for rich individuals to bet on whether or not Shiverhuahua can be defeated and the fight has been fixed by McCoy for the B-Class hero to win. However, Shiverhuahua turns out to be stronger than expected, as it easily overpowers and nearly kills Mad Devil Yankee. Before long, Saitama interrupts and rescues the B-Class hero by punching Shiverhuahua to death.

Abilities and Powers
Shiverhuahua's true disaster level is Wolf according to the Hero Association, despite them fakely classifying it as a Demon-level threat to the public. However, Mad Devil Yankee, a B-Class hero, after being overpowered by it during a fight, has remarked that Shiverhuahua is too strong for a mere Wolf-level threat.

Physical Abilities
Enhanced Strength: Shiverhuahua's strength is considerably high for supposedly being only a Wolf-level threat. It could easily overpower a B-Class hero without him being able to fight back properly.

Enhanced Speed: Shiverhuahua is able to deliver its punches fast enough that a B-Class hero could not counter and evade.
