A mermaid with a positive attitude who pushes ahead no matter what. She loves to swim, but is troubled by the fact that her large breasts don't allow her to swim as well as she'd like.
HR Rarity: Never seen a mermaid before? Could you, you know, stop staring so much...? It's embarrassing.
SR Rarity: Despite what you may think, I'm actually quite bothersome, and I'll just never leave your side.
