Enter the Octobot King!

Enter the Octobot King! is the fifth and final boss mission in singleplayer Hero Mode. DJ Octavio, leader of the Octarians, is the final boss.

Octo Valley
After completing every previous level in Octo Valley, the Boss Kettle on the UFO floating above the valley will finally be unlocked. After this, the player must make his way to the top of the 5th area, where there will be a super jump pad waiting for him. This pad will launch the player to the UFO, which will, upon entering the Boss Kettle, fly away and carry you to the final boss.

Boss Appearance
Unlike most Octarian fighters, which appear to be severed tentacles, DJ Octavio is an actual octopus in his entirety. He resembles a giant red-purple octopus with a permanent angry expression on his face. His tentacles bare large green X-shaped scars, similar to the ones seen on other bosses. On his head sits a large gold helmet, fashioned similar to a samurai helmet, with an octopus-shaped emblem on the front. He sits inside of a flying machine equipped with a pool of purple ink and a turntable, which he plays using plentiful stalks of wasabi. The turntable has four cannons on the front, two extendable fists and a set of thrusters that allow it to stay airborne.

Attacks
The boss stage and boss itself uses everything the player has learned throughout Hero Mode. During the boss fight with DJ Octavio, he will use several techniques to try and splat you or crush you:


 * Octorpedoes, which are launched from the cannons in the front. They vaguely home in on the player, but are primarily used to cover the ground in ink.


 * Two giant fists that can be extended to try and punch the player. If shot at before they hit the ground, they will fly back into the machine and damage it, pushing it backwards through the long corridor.


 * Small, discoball-like spheres that hatch into a random Octarian when it lands. It can be shot at to make them explode into your ink.


 * The Octarian version of the Inkling's Killer Wail. Unlike the Inkling's version, this version cannot hurt you if you are hiding inside your own ink.


 * A massive octopus-shaped bomb that explodes into a massive amount of the ink. If shot back at DJ Octavio, he will continuously punch it back until he runs out of fists with which to hit it back and gets hit. These are the key to his defeat.

Sunken Scroll Appearances
Shown here is the Sunken Scroll of mission 16, Propeller-Lift Fortress. It seems to be that DJ Octavio can assume human-esque form, as Cap'n Cuttlefish can do the same.

Trivia

 * After being defeated for the first time, DJ Octavio can be seen in the world map, imprisoned in a snowglobe-like tank by Cap'n Cuttlefish.
 * If the player chooses to fight the final boss battle again, the dialogue will change into a scenario where DJ Octavio escaped from his prison and recaptured Capn' Cuttlefish.
 * If one looks closely, they can see that the massive octopus shaped bomb that's fired at the player at the end of each phase is actually wearing a pair of sunglasses.
