This is my slightly altered version:

Gundam: Sandrock, Wing Zero
Age: 15
Gender: Male
Nationality: Arabian descendent
Birth place: L4 colony cluster
Family:

Father (killed in the series), 

mother - Quatrine 

(died giving birth to Quatre), 

29 elder sisters. 

40 Maguanac Corp soldiers.

Contact: Dr. H
Height: 154
Weight: 41kg
Accepted star sign: Cancer
Features: Blond hair, very fair skin. Dark blue-green eyes. As un-Arab-ish looking as one can get. Refined, aristocratic features. A bishounen. Still has pre-teen, not yet deepened voice. 
Special abilities: Strong telepathy, (Extra-sensitive towards Heero) good at battle strategy, negotiation, politics, business, and leadership (led the Gundam pilots to battle when Heero is needed else where). Quatre also built Wing Zero, the most deadly Gundam. He is also a talented musician, can play violin, piano etc. Quatre is the glue that units the Gundam pilots to fight together.
Personality: Peaceful, gentle, kind-hearted, sensitive, however not a pacifist. He shreds tears often and gives people the illusion of his weakness. He helps out all Gundam pilots at one time or another. Quatre is well respected by everyone regardless of his open showing of kindness and emotions throughout the war. However, his telepathy caused him to be mentally unstable and went crazy after seeing his father killed in front of his eyes. Yep, he had laughed maniacally at that, with tears in his eyes (see his resemblance with Heero?). During that time, he built the most deadly Gundam - Wing Zero, and used it to destroy the resource his father sacrificed his life to keep from OZ, and destroyed one evacuated colony. He was snapped out of his crazed mind by Trowa's attempt at sacrificing his own life. 
Comments: Ain't he adorable!^^ I love Quatre, with all my heart! I can be definitely classified as Quatre-obsessive. How did I ever gotten myself into this stage? Well, first, his adorable voice; second, the way he had the Gundam boys around his little finger; thirdly, oooh... when he let out the little devil within as he blew a colony and Trowa's Gundam to pieces. Okay, he's just out of his mind at the time, controlled by his awful creation - Wing Zero (my favourite!). However, I'm squeamish over the characterisation of Quatre as this sadistic, psychotic dominatrix in some fan-fictions. They amuse me, but I don't like any guy he is with to be a weakling. I really, really, really HATE weak men! Quatre is my only exception. Yeah, so perhaps I'm the female version of Wufei. Maybe that explains why I put up with him, and dubbing a little in 5x4. But Heero is still the best lover, I sincerely believe, no matter how slutty I am in reading x4s!
