Nereus is an anthropomorphic hippo deity dressed in a bright red ruff and tutu. He can't speak, which pretty much defines his whole vibe—fans often note that his inability to communicate makes him genuinely difficult to pin down in terms of actual function or role. As far as anyone can tell, he doesn't seem to do much of anything, which honestly might be the whole point. He's just. there, existing in his weird little outfit, defying easy explanation.
