What is BrainRot Fight? It is a massively popular game where you buy AI-generated monsters from lanes and have them battle bosses that appear on the field every 20 minutes.

Monster Rank Tier List Strongest Rank: Missing The rarest in the world.

An axe floats in front of her, which she uses to fight. Details: The biological daughter of the sea god Poseidon. Poseidon was kind, so she naturally learned etiquette, but Mermaid is a clumsy airhead and always makes mistakes. She has loyal subordinates.
