Originally an Octarian known as Ahato "Acht" Mizuta, Dedf1sh would defect from the Octarian Military and would volunteer to become a test subject for Sanitization which would result in her focusing more on music and loose most of her memories and personalities. However, upon being sucked into the Simulation known as Order, she started to regain her memories back remembering her old friend, Marina who also defeated from the Octarians. Dedf1sh helped Pearl and Agent 8 rescue Marina and stop Order from being completely corrupted, after which, she would return to Splatsville making nea music and occasionally play Table Turf.
