Commander Tartar, also known as the telephone, is the main antagonist of the Octo Expansion. It created the Sanitized Octarians by sterilizing them with primordial ooze.

Mr. Grizz, CEO of Grizzco Industries is the main antagonist of Splatoon 3 Return of the Mammalians. He is the creator of Fuzzy Ooze.

Notable species


Inklings are a sentient race of squid-like humanoids who are the main playable species in the Splatoon universe.

Octolings are the Octarian equivalent to Inkling, being octopus-like humanoids. They serve the Octarian military, while many have left and integrated into Inkling society. Jellyfish can be seen scattered in the cities and across various Stages.

A species and type of currency in the Splatoon series. Their sole use is to increase the number of slots on gear or reroll all gear abilities on a select piece of gear.

Creatures that appear in Octo Valley, Octo Canyon, and in The Crater. The player must rescue one at the end of every level in order to proceed in the story.
