Echo was one of the first bat ponies created on Batponies.wikia. She was a collaborative effort between several Anons, taking almost three threads to create. She is often seen as the thread's mascot, and has some popularity outside of /mlp/. Someone even made her into a plushie.

Her personality is often portrayed as silly and playful, sometimes mischievous. A bit eccentric, but always upbeat and uplifting. She likes to eat a lot, especially really sweet and exotic fruits like lychee and mangoes. In more serious instances in stories of her appearance, she is usually a bit more assertive.

In the earliest one-shot stories involving her, she was often portrayed as trying to trick Anon into falling asleep so she could draw his blood, uninhibited.
