Great Zapfish

The Great Zapfish is the main subject of Splatoon's single-player mode, Octo Valley, being a very large Zapfish that powers Inkopolis.

History
The Great Zapfish is a giant animal circling Inkopolis tower, powering the city. According to the first Sunken Scroll, The Great Zapfish is 100 years old, and powers the entirety of Inkopolis. However, when the player enters Inkopolis Plaza for the first time, a news report turns on stating that the Great Zapfish has been stolen, and is believed to be linked to the UFO that crashed earlier outside of the city. However, when the player goes to Octo Valley for the first time, Cap'n Cuttlefish, a veteran of the Great Turf War, tells the player that the Great Zapfish has been stolen by the Octarians as an act of revenge for losing the war. Cuttlefish teams up with the player so they can take back the Zapfish, but first the player must take back every regular Zapfish before obtaining the Great Zapfish.

After collecting all regular Zapfish, the player finds the Great Zapfish in the hands of DJ Octavio, leader of the Octarians, who baits the player into saving it before sucking it up into his weapon. After defeating Octavio with the help of Agent 1 and Agent 2, the Great Zapfish is saved, and can be found resting on Inkopolis Tower for the rest of the game.

Appearance
Unlike other Zapfish, the Great Zapfish is massive and more similar to the real-life electric catfish. It has yellow curled whiskers that give off electricity, an orange mouth, peach face, a dark blue body, a small, dark blue tail with lime green along the edges, and similarly colored fins.
