Cipher
Cipher is a character that shows up in Splatoon 3's DLC, Side Order. It is a digital entity whose appearance is based upon the Luciferidae prawn, and it runs the shop Cipher's Siftings, which offers various cosmetic items and locker decorations to the player. Cipher's gender identity is unknown, but promotional material from the SplatoonNA Twitter account has referred to Cipher with it/its pronouns.
Cipher's origins are not entirely clear at the present moment. In-game dialogue implies Marina did not create Cipher herself, but whether Cipher was created by another Memverse programmer or if it just came into existence on its own after the defeat of Order is not known. It gets its strange speech patterns from its code being patterned after the blended thoughts of many people brought into the program, and it is currently the only Memverse node beginning to gain awareness of the digital nature of the world. It runs its shop to obtain Prlz, which it uses to learn more about the Memverse because of the knowledge stored inside them.
"Cipher's Siftings is open for dealing, anytime and for all time."
"Already you bring change to this world. But there is more change to come. Your bringing is incomplete."
"I hope that your desire is found among my siftings."
"Gratitude for your persistent support is warranted. I hunger to see what changes you bring."
