Darkest Depths

The third eldest of the pod and the definition of looks can be deceiving. Despite looking more fragile than her siblings, Darkest Depths is the most dangerous and unpredictable. She has a habit of kidnapping ponies and dragging them underwater to scare them only to let them go and using her singing to manipulate fights between said panicked pony and anyone they seek help from. Operetta usually leaves Betta to deal with her as she is secretly scared of her. Darkest Depths is oblivious to this fact.
