Original character. :D
Her name is a pun (but she's a cyborg), and she has already a backstory.

INSPIRATION --> http://www.youtube.com/watch?v=_gtyGF4zKA8&feature=related (This song is a drug)

She was a simple little Brazilian Three-banded Armadillo (from a Zoo in North America actually, lol). But after some years, she was sold to a laboratory that sent her to an experimental area of the Area 51.
They modified her DNA in order to create an intelligent weapon, but they managed to do it too well: after 18 years of developing into a capsule, in a liquid to preserve her, she started to think of her own.

Two years later, they told her the truth. She didn't wanted to be a weapon, and when they replied to her "But you need us", she replied "Why should I take orders from you?!". Then she ran and managed to steal an experimental vehicle ( a sort of little space ship). She saver herself and now she crosses the Galaxies, helping who needs it.

She belongs to me, so does the plot.
