Carla

Carla is a supporting character in Fairy Tail.

She is a white Exceed (a race of small, winged, talking cats from the world of Edolas) and serves as Wendy Marvell's loyal partner and companion, much like Happy is to Natsu.

Personality-wise, Carla is very mature, sharp-tongued, dignified, and often acts like a strict, no-nonsense parent figure toward Wendy (and sometimes the rest of the guild). She frequently scolds others for being childish or reckless and has a proud, somewhat haughty attitude.

She has the ability to use Aera magic, which allows her to sprout wings and fly, and later reveals powerful precognitive abilities through her "clairvoyance" (future vision).

In short: Carla = white cat, sarcastic mom-friend to Wendy, flying magic, future-seeing, very proper and easily annoyed by Happy's antics.
