Oarfish

Oarfish is a teenage independent journalist who appeared in the show at the start of season 2, but only started having bigger plot significance at the start of season 3. She is a member of The School. An ongoing subplot beginning in season 3 implies that she may be guilty of manslaughter, and corroborated with a corrupt police officer in order to conceal the evidence. Given that she was cryogenically frozen for much of seasons 4 and 5, she has yet to be interrogated further about this matter.

Personality
She is shown to be caring, thoughtful and hopeful. She believes that there is good in everyone and always puts others before herself.

Biography
Oarfish made her appearance at the beginning of the second season as a minor side character, often appearing in the background and interviewing fish who have recently returned from missions. She started having more character development at the beginning of the third season in the Memories Arc, mostly through helping her adoptive father, Crab, recover from his PTSD after his time serving in the Hillbilly Genocide/Hillbilly War. Oarfish played many major roles in the episodes following, proving herself to be a respectable member of The School. She was one of the many victims of the attack on Atlantis and has suffered nearly-lethal wounds in the explosion and has been put into cryogenic sleep for the rest of season 4 and majority of season 5. Near the end of season 5 her and the other victims have been unfrozen. Oarfish has been shown to feel really shocked and confused, having missed out on many key events in The School's life.

It’s implied throughout one of the show’s many subplots that Oarfish may have committed manslaughter. Rockfish, near the end of the second season, discovers evidence discarded by an unidentified police officer that indicates a fish being murdered, namely a sharpened piece of coral stained with blood, a few chunks of fish meat, and some teeth that had been broken off of some sort of creature. He begins to investigate this matter further, leading into season 3, when Oarfish is introduced. Over the course of this subplot, which is still ongoing, Rockfish finds more and more evidence, much of which is intentionally misleading. Slowly, he pieces together the puzzle, and concludes that Oarfish was likely colluding with a police officer to cover up a murder she committed. The reason why she would do this is currently unknown, but many fans have speculated that she was trying to shut someone up who was trying to get the word out about issues within the justice system. As an independent journalist and a disgusting centrist, what Oarfish wants more than anything is for the status quo to be enforced, so any political turmoil is worth avoiding at all costs to her. It only makes sense that she would want to silence that fish permanently, and of course the police would be more than happy to help. We have not gotten confirmation of this, as Rockfish has yet to find time to interrogate Oarfish after her waking up from being cryogenically frozen.
