Acht, also known by their stage name Dedf1sh, is a musician in Splatoon 2: Octo Expansion whose songs can be heard around the facilities of the Deepsea Metro. Once a normal Octoling, they entered the Deepsea Metro's underground test facility and became sanitized, losing their free will.[4] They make their first physical in-game appearance within Splatoon 3's DLC campaign, Side Order, in which they assist Agent 8, Pearl, and Marina as they climb the Spire of Order.
