King Salmonid

King Salmonids are enormous Salmonids that appear as bosses in the Xtrawave of Salmon Run Next Wave in.

Description
One King Salmonid appears in an Xtrawave after the shift finishes and at least one of the four players has a full Salmometer. The crew will need to defeat the King Salmonid within the time limit while fighting other Boss Salmonids. It can be defeated by using the player's main, sub, and special weapons. Additionally, any Golden Eggs collected during the Xtrawave can be thrown at the King Salmonid to deal massive damage to it.

Only one type of King Salmonid, Cohozuna, has been revealed so far.

However, a lot of hints appear in Splatoon 3 and SplatNet 3 that there will be more King Salmonids.

Quotes
"Squid Research Lab is excited and more than a little scared to reveal the existence of a King Salmonid. This unfathomably terrifying creature can be scientifically described as "ginormous." We hope to release more details soon."

"Sadly, it's not all break rooms and promotions in the working world. Sometimes you have a tough day at the office and get attacked by a King Salmonid. HR recommends fighting it off with an egg cannon (you could earn bonus fish scales) and then taking a personal day."

Trivia

 * After Wave 3 ends, if an Xtrawave is activated, the success jingle will be distorted, indicating a King Salmonid will spawn.
 * Beating the Xtrawave changes the success jingle to a triumphant fanfare.

Etymology
The English name is derived from "king salmon" and "Salmonid".
