In the past she tried to conquer the world by flooding it. However, Rosebud manage to defeat her by drying her out of the water and locking her in a trunk.
Since she is a evil mermaid, she has a nasty attitude. When she tries to make people help her, she pretends to be a good mermaid.
Esmeralda has long dark pink hair with a yellow starfish, a blue conch-shell bra and a necklace made of gold. She also has a long, green fish tail and freckles on her face.
