Remy's family owns a failing restaurant.

His family consists of: mother, father, 2 sisters, a brother, and Remy himself.

His father is the head of the family, and is the one who's forcing everyone else to be a part of the family business. It's so bad, that the siblings can't get out in the world and study for what they want to pursue in life, they're giving all their time to the restaurant.

The family fights a lot, including yelling in the kitchen. Remy was initially a cook, but during one of the yelling matches between his siblings, he got distracted, slipped, and dropped a boiling pot of soup on himself and his brother. They both got severe burns, and Remy lost an eye then. After that, he was given a rose eyepatch and moved to be a waiter instead of one of his sisters.

Fast forward in time, Remy decided to try to get another job to bring money into his family and try to help their situation. He got a job as a cook for some shady people who liked him too much, and offered to join them. That's how he got a fish costume to conceal his identity during crimes, and that's when...he suddenly developed MPD (multiple personality disorder) or DID (modern term).

When he wore the costume, or more specifically the mask, he became SawFish — a loud, unhinged version of himself that represents all his repressed anger, feelings and desires.
