In the Splatoon series, Squid is a generic term used to refer to the Inklings' squid form. Inklings are capable of transforming between humanoid and squid forms at will. The squid form allows them to swim swiftly through ink, climb walls, and hide from enemies. This transformation is a key gameplay mechanic, as it enables players to navigate the game's environment and engage in combat strategically. While not a character with a specific personality or narrative arc, the squid form is integral to the identity and abilities of the Inklings within the Splatoon universe.
