By spirit, he is literally the most innocent soul to come across. But make him angry, and that's a different story for you.

    Just as a heads up, you know?
____

Name~ Fully, his name would be Micky Sean Ricky. But he just has his name dimmed down to just be Mick Rickey.

Age~ He's thirteen years old by now. How interesting

Gender~ He, it's a he. A boy, male, a guy. What wording do I have to type to explain the obvious?

Species~ Supernaturally, he is a half mouse boy

Sexual Preference(s)~ That is currently unknown.. An innocent boy as such as himself just doesn't even know what sex is yet. Maybe you can help him find out? ;)

Common appearance(s)~ As for humane form, his hair is kept long and Golden blonde. Golden blonde fur covers his ears, but his tail is exposed nearly pink flesh. His eyes are also large and a very light golden coloring as well.
Full on mouse? Well, he changes from blonde to being completely covered in dirty gray hair. And from light golden eyes to beady black ones.
The more feral, angry, and anthropomorphic self is the exact same, but slightly larger and is seen carrying tiny sharpened hand made metal blades.

Overall Personality~ He is normally quiet, shy, and easily able to become nervous until he warms you. Normally.

Likes~ Whatever he can nibble on and kind individuals.

Dislikes~ Being forced to be used and taken advantage of. As well as being threatened with possibly being squished.

Common strengths~ Size doesn't matter, he however uses his size to help him slip out of sticky situations quickly.

Obvious weaknesses~ He is very fragile in his anthro and full on mouse forms. Hence why he also fears getting squished.

Abilities~ Micky Sean Ricky has the ability to summon his clone "army" when he needs them most, or sometimes by accident. He seems  to be able to mentally coordinate how the clones should react to his situation unless otherwise coming to aid by free will.

Skill(s)~ Mick is pretty darn kick àss to say the least. He can scale/climb walls ten feet high. As well as jump react, and run faster than a kangaroo rat. He also can converse with animals.

Background information~ On an odd day as it seems, a scientific project was born. Why not use the genetic material taken from a trained intelligent mouse,  combine the material with human genes by doing the scientifically impossible and impregnating a human male? Then take the produced child offspring and clone them a thousand times over with "Kill, steal, destroy" programmed into their brains?
The original idea was called "project Mouse boy." But, there was a major flaw in this project. The mouse boy clones are completely harmless, or seemingly anyway.
Micky, the original first offspring, was "accidentally" set free to explore the world and presumed dead because he wasn't needed. The project was supposedly a bust and shut down.. Or was it?

Extras~ Often, Micky will be prone to saying "eep" at the end of his sentences. Especially when he is very nervous, which will also lead him to stutter.
Yet you should know this now, do not make him angry. His mouse normal form changes from

    To what you see as the second image on this page. Making him a nearly cold blooded and partially feral killing machine.
    His voice will also be squeaky at times.
