Sea Rescue Hero "Selkie" (海の救助ヒーロー セルキー Umi no Kyūjo Hīrō Serukī?) is a Pro Hero and Captain of the Oki Mariner.
Spotted Seal (ゴマフアザラシ Gomafuazarashi?): Selkie's Quirk allows him to do anything a spotted seal can. He can hold his breath for long periods of time 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.
