Octarian

Agent 3 against an army of Octarians.

The Octarians are a race of octopus creatures and the main antagonistic species of the story mode in Splatoon. They reside in Octo Valley, and are responsible for stealing Zapfish from Inkopolis. Their main ink color is purple/magenta. At one point the Octarians were a neutral species coexisting with Inklings, but this ended as result of conflicting interests of territory that lead to the beginning of the Great Turf War (in which the Octarians lost).

Unlike Inklings, the species includes a great amount of sub-species that act differently from each other. Like Inklings, certain Octarians can switch between mollusk form and humanoid form at will.

In the manga series

In the end of the fan-made issue of Splatoon, a then unnamed Glasses-Kun flies over a bunch of Octotroopers and Octoballs. It's most likely that they would not appear in the manga again. But will possibly do so due to the Inkopolis Tower not having the Great Zapfish on it.
