Octopus

Octopus is the Quirk used by Innsmouth.

Description
Octopus provides the user with the physiology and skills of an octopus, such as multiple elastic appendages, suckers and the ability to spit ink from their siphon-like mouth.

Trivia

 * The Quirk is similar in nature to Ikajiro Takobe's Octopus (Squid), although the two characters don’t seem to share any apparent relation.
