Just an Arrancar I made a while ago.
Hey, let's make a profile for him.
-----
Name: Luna
Age: Who cares?
Sex: Male
Hair: Blonde-silver
Eyes: Silver
Abilities/Powers:
Cero - A near-standard cero, about the same power as a Fraccion's. It's silver instead of crimson.
Bala - Same as cero
Hierro - Eclipse has demonstrated the ability to use Hierro, a technique used by Arrancar to harden their skin. His, however, is quite weak, qiven his strength
Sonído Expert - Eclipse is quite proficient in Sonido, with speed great enough to keep up with at least a Lieutenant-ranked Shinigami
Expert Swordsmanship Specialist - While not as proficient as the Espada, Eclipse is able to fight on-par with at least a Lieutenant-ranked shinigami
Expert Hant-to-Hand combattant - Eclipse is quite strong physically, able to incapacitate at least a fourth-seated officer bare-handed.
****
Zanpakuto: Luna (Spanish for Moon, obviously)
Luna resembles an ordinary katana, the expection being the guard which resembles a golden crescent moon.

Resurrección - Eclipse de Luna
In his released form, Eclipse gains a great about of power, and resembles somewhat of a cat mixed with a dog with crescent moons jutting out of who-knows where.
(I'll finish this later, and maybe put a picture of Eclipse del Luna for anyone who cares.)
