Selkie

Selkie (セルキー), also known as "Sea Rescue Hero" (海の救助ヒーロー), is a Pro Hero and Captain of the Oki Mariner.

Appearance
Selkie is a man with a muscular physique, the appearance of a humanoid spotted seal and a gray beard. He sports a full body wetsuit as his hero costume featuring yellow goggles, retractable flippers and a stylized "S" featured on the shoulder.

Personality
Selkie is a confident, kind and professional individual who prioritizes his hero work and protecting his crew. He has a tendency to try and make himself look cute despite his macho appearance, much to the annoyance of his sidekicks.

Vs. Hero Killer Arc
Selkie first appears aboard the Oki Mariner with Sirius and Froppy. Initially he yells at them for slacking off, but apologizes using his cute persona after he finds out they've finished all their work. He and the crew later sail off to pursue stowaways who stole cargo from a trade boat. When they happen upon the supposed criminal ship, Selkie goes without Sirius and Froppy to investigate.

He and two of his sidekicks investigate the ship, only to be trapped inside by Innsmouth's lackeys. Selkie only returns to the action when Froppy relays an S.O.S across using Sirius's radio. Selkie finds Froppy and Sirius overpowered by Innsmouth himself. Innsmouth blinds Selkie using his ink, but Selkie uses echolocation to find and defeat him. Afterwards, the stolen goods are returned and Selkie claims that Froppy will make a great hero one day.

Quirk and Abilities
Spotted Seal: Selkie's Quirk allows him to do anything a spotted seal can. He can breathe under-water and has above-human strength. He can also utilize echolocation when traversing dark waters or when his sight is hindered during combat, as seen during his fight against Innsmouth.
