Sylpheed

Sylpheed is a member of the Archenemy species of the same name, a spirit of wind.

Appearance
Sylpheed has the stereotypical appearance of a fairy: a girl the size of a person's little finger, with wings like those of a dragonfly. She has blonde hair tied into a ponytail, green eyes, and wears a revealing outfit.

Abilities
Size and weight alteration: As an spirit of wind, Sylpheed can change both her apparent size and apparent weight by gathering the air. One way she uses this is to accelerate in a large form to build up kinetic energy, then shrink to a smaller form to focus the energy on a smaller point, similar to a tank gun's armour-piercing round.

Superhuman Speed: Sylpheed can reach speeds greater than the speed of sound, provided that she has sufficient space (several hundred metres or several kilometres) to accelerate. She can use this to attack by simply ramming a target, the result being comparable to a rifle bullet.

Superhuman Durability: Sylpheed is durable enough to crash through glass at supersonic speeds with her body.
