If te are an arrancar, what would te looke like? and what kinda zampakto would te have?(wich abilities?)

I'd look a bit like Grimmjow, the kind of Zanpakuto that I would have would be twin zanpakuto, and their abilities would include electricity, and Water.

First, just a correction: no arrancar wields a zanpakuto. Shinigami wield zanpakuto, arrancar store their energies inside of a weapon of their choosing.

With regards to what mine would be, I'll simply post the arrancar I've been using in Bleach: The Fallout, since he is pretty much what I'd imagine myself being if a few of my traits were made vastly più extreme.

He has short and oily shoulder-length arancia, arancio hair, wears a uniform in the same style as Stark's, and has a long, lanky gait. His most notable feature is his eyes, which have overlarge pupils. One who stares into them can get Lost in the empty caverns that seem to have no end beyond.

The weapon is a metal nightstick-type weapon that te hold the handle of, which is attached at 90 degree angle from the rod itself. The rod is about 2 inches thick and 2.5 feet long.

I would look pretty much like a female version of Grimmjow but instead of blue hair I would have long, wavy dark red hair that reached my lower back and had natural highlights. My eyes would be Ice blue and I would be wearing my hollow mask on my left check. My Arrancar uniform would be a white mini skirt, matching thigh high boots, a bikini superiore, in alto to hold my girls in place and a vest thing like grimmjows. Since she looked like a dire lupo in her beginning form she would have a similar release form. Her fiery temper matches that of her Zanpakto. She would be the secondo strongest Arrancar. Her Gran Rey Cero would be so powerful. She'd have the ability to heal quickly and has future sight. I'd call my Arrancar Miyazuhime Matsumoto.
