Happy

Happy (ハッピー Happī) is a cat with some magical power, which may be the reason for his ability to speak, and is a member of a Fairy Tail Guild's Team Natsu along with Natsu Dragneel, Gray Fullbuster, Lucy Heartfilia, and Erza Scarlet.

Appearance
Happy takes the form of a small blue cat with a red scarf around his neck. When using his magic he can grow a pair of large angel-like wing that allow him to fly around and carry others, as well. He has a unique ability which allows him to speak, but when he does he has a tendency to say peculiar things. His tattoo is located on his back that is usually covered by the scarf. Because Happy is a cat, most villains don't count him as a mage or having an special abilities because his magic isn't used for battles (even though he did fly into the Duke Evaroo and injure him)

Personality
"Aye."

- Happy's catchphrase

Happy is the one of the more eccentric members of Fairy Tail, and usually provides comic relief for the team in bad situations.
