Commander Tartar in its telephone form.
|First game||Splatoon 2|
Commander Tartar also refered to as the Telephone for most of the Octo Expansion DLC for Splatoon 2. It is the main antagonist of the Octo Expansion as well as its final boss.
Tartar was originally saw hope in the Inklings and Octarians, but soon became disgusted when he realised that they were as foolish as humans were. He then created his own directive and started to create a new form of life that would be worthy of its knowledge, while annihilating the existing lifeforms on Earth. The Sanitized Octarians are its creations, spawned from the biomass it has collected from the remains of its previous test subjects and refined into "the perfect life".
It is eventually exposed by Agent 3 while it was trying to blend Agent 8 and Cap'n Cuttlefish like the other test subjects. While Agent 8 is trying to find a way to the surface, Tartar brainwash Agent 3 and make her fight Agent 8. Agent 8 defeat her and free her from Tartar's mind control before finding out that Tartar plan to use a weapon called the NILS Statue to eradicate all life on the planet and replace them with their Sanitized equivalent.
Agent 8 face Tartar in a final Turf War to reduce the power of the statue who use sunlight to charge its weapon. Agent 8 manage to cover the whole statue with her ink and Tartar fire the weapon despite it not be fully charged only to be stoped by Pearl's Killer Wail who manage to overpower NILS' blast and destroy Tartar in the process.
