Mermaids are a species that appears in the Super Hero Galaxy franchise. Mermaids are fish people that live anywhere in the sea. They exist from ancient years and are mostly water users.
Mermaids are legendary aquatic creatures with the heads and torsos of either an animal or human and the tails of fish and are born similar to how babies are born on land.
Mermaids also lose their clothes they're wearing in land form which only reappear when they change to land form again.
There's a subspecies know as Gill-Less Mermaids, mermaids without gills. Because of that they can't breathe underwater. They can hold their breath for at least 12 hours before needing to resurface but with more practice Gill-Less Mermaids can stay under for much longer. When Gill-less mermaids remain breathless, they do not die. They sleep underwater, and just awaken when they breathe air again. They can only hold their breath in mer-form.
