Disaster Neko

Fury Cats are evil versions of kittens and calico cat parents that appear as enemies while Fury Bowser is active in Bowser's Fury. They are black with red eyes and ears, have spiked tails and fur on their heads and backs, and have a red aura emanating from them. Calico cat parents turn into larger Fury Cats than kittens do. When Fury Bowser appears, all kittens and calico cat parents on Lake Lapcat turn into Fury Cats and chase after Mario if he is nearby, damaging him if they make contact. If Mario is holding a kitten when Fury Bowser wakes up, then he will drop it after taking damage; if a kitten is riding Plessie when Fury Bowser wakes up, then it will teleport back to its original location. When Fury Bowser leaves, all Fury Cats turn back into kittens or calico cat parents.

Fury Cats are virtually invincible, though hitting them with fireballs or boomerangs knocks them a short distance away, and clawing at them as Cat Mario or Bowser Jr. hitting them with his Magic Paintbrush may stun them for a moment. Fury Cats that come into contact with water, lava, Invincible Mario or Lucky Cat Mario vanish and reappear in their original locations as kittens or calico cat parents when Fury Bowser returns to his inactive state.
