Diss-Pair

"Meet Diss-Pair, the odd-couple duo delivering discordant ditties that have turned the music scene upside down. The group is made up of Ikkan, former bassist of the world-renowned Squid Squad, and Warabi, the up-and-coming prodigy beatsmith. These two are a mismatch made in heaven. When crafting new songs in the studio, they avoid each other at all costs to ensure each track maintains its one-of-a-kind edge and tantalizing tension."

- Live from Squid Research Lab

Diss-Pair is a musician duo comprising the former Squid Squad bassist Quinn and the Octoling DJ Mashup. Their music was added to Splatoon 2 in Version.

Their songs mix elements of metal and EDM and feature low, husky vocals reminiscent of those heard in Ink or Sink and Metalopod.

Members
Prior to their names being localized, Quinn and Mashup were referred to in official Live from Squid Research Lab posts by their Japanese names, Ikkan and Warabi.

Quinn
Quinn is an Inkling and the band's bassist, formerly a member of the Squid Squad. He did not like how little tension there was during the songwriting process in Squid Squad, which is most likely why the band broke up. He is a fan of metal, utilizing deep riffs and husky vocals he occasionally used in the Squid Squad, and pairs himself with the younger Mashup, trusting that he will keep up the tension in their music.

Mashup
Mashup is an Octoling who is described as an up-and-coming prodigy beatsmith. He is a successful musician who regularly travels around the world, traveling to over 20 countries in a single year. His parents are famous actors, and as a result, he was exposed to many different types of music from around the world at a young age. He grew up with classical music education for gifted children, but got into electronic music in his teenage years, becoming famous by handling remixes of other popular artists. According to Quinn, while his demands seem all over the place, he is actually quite clever and intelligent. He met Quinn on a tour overseas, leading to the two joining together, although, from an outside perspective, it looked like they were fighting. According to the Japanese Fam vs. Friend dialogue, he is friends with Marina.

Trivia

 * Both of Diss-Pair's tracks have titles referring to types of illnesses, specifically seasickness and motion sickness.

Etymology
"Diss-Pair" is most likely a combination of "dissonant" and "pair" (referencing the two members who sometimes do not get along), as well as a play on "despair".

Warabi's name comes from the Japanese word for bracken, "warabi", which is used to make various Japanese dishes. Bracken with octopus is considered a bad pairing of foods, making it "合食禁" (gasshokukin)

Ikkan's name comes from the word "ikkan" (一貫), a unit used for sushi.
