Banshee

She opened her mouth to give a cry of approval but quickly shut it at the sound that came out. Rather than the delightful hum of a young hatchling, the room crackled with the sound of an electric hum. 'This young dragon will prove to be quite interesting,' Nia thought.

Banshee earned her name from a very young age because of the loud static noises she makes when she attempts to speak. Though not quite mute, Banshee prefers not to talk as the electric noises tend to hinder her. Instead she prefers to communicate through body language.
Banshee also has an interesting ability to go along with her humming. Given prolonged exposure, lightning bolts will come shooting from her mouth. So strong is the electricity within her, that power packs have been created to help her focus her energy. While these do assist, they don't entirely abate the electricity; it constantly flows through her and can often be seen through the small holes that are splattered across her hide - the effects of pure electricity themselves, though it seems she is not bothered by them.

Though Banshee is a powerful dragon, she is a sweet tempered dragon and often eager to assist in projects (especially those involving electricity) around the clan.
