ECHO: OCTOLINGS CLAIM THEIR TURF
Octolings Splat Jump onto the battlefield, as Echo Fighters of Inkling. The Octarian society is more militaristic than that of the Inkling, so their changes alter their playstyle to be more aggressive. Instead of using the Splatoon 1 Splattershot for their attacks, they use the Splatoon 2 Dapple Dualies (this is a cosmetic change, however). The rest of their stuff is based on Splatoon 2, as the Inklings are largely based on Splatoon 1.
Property Change: Ink Effect. Unlike Inkling, where knockback is the primary effect of Ink, raw damage is what Octolings get from it. A fully inked opponent takes x2 damage, and it decreases by .1% every 10% the opponent is un-inked (a 90% inked opponent takes x1.9, for example. Everything else is identical).
Down and Back Air: These are largely the same, except they now use ink. This increases their Sweet Spotted damage and knockback (D-air goes to 17%, B-Air goes to 15%) as well as applying ink to opponents. To compensate, it increases endlag on these moves, and if you don’t have any ink and try to do these attacks they do literally nothing.
Neutral Special: Dapple Dualies. Octoling fires forward with both of their Dapple Dualies. As these are two weapons, the damage output is increased (1.5x). Like the dualies in Splatoon 2, Octoling can roll during this attack, which is pretty much a standard roll. To compensate, lag is increased and it decreases Ink at a faster rate.
Side Special: Dynamo Roller. Octoling’s Side Special is an interesting variation on Splat Roller. It moves incredibly slowly, about how much Splat Roller moves inkless. It also uses up ink very fastly. In contrast, it does huge amounts of damage (25%), skips the burying and just kills at high percents, and meteors if done in the air.
Final Smash: Inkjet. The Octoling uses Inkjet, one of the Special Weapons from Splatoon 2. Functionally, it’s almost Identical to Diddy’s old Final Smash, with the Octoling flying around and shooting ink.
