Squid Girl

Squid Girl (イカ娘, Ika Musume)

Voiced by: Hisako Kanemoto (Japanese); Christine Marie Cabanos (English)[1][2][3]

Squid Girl appears as a young humanoid girl with blue cephalopod tentacles for hair. Her goal is to take over humanity as punishment for the pollution done to the sea. However, after causing damage to Lemon (which she planned to use as a base), she was forced to work as a waitress to pay for the damages. She possesses numerous squid abilities including extending her tentacles, regenerating severed ones, spewing squid ink from her mouth, glowing in the dark like the firefly squid, swimming and breathing underwater. She also has bracelets that enable her to have weight-shifting abilities.^{S2 Ep. 2c} It is later revealed that what appears as her white squid-shaped skullcap is actually part of her head, so fatal consequences might occur if someone was to attempt removing her "cap". The two fins on her "cap" can move like actual squid fins, although she was initially ignorant of the fact. Her favorite food is shrimp, and she greatly fears natural predators of squids like sharks and killer whales to the point that even swimming floats of such creatures terrify her. Although generally immature at first and often getting herself into mischief from the start, she is a fast learner, able to master complex things such as math and other languages in a short period of time.
