I don't really know what to do with this char yet, or if it's even a char for that matter.
Dubhe could be one of Polaris' guardians or something.

She's referred as to female, but is actually genderless.

Dubhe's primary means of attack is a laser beam.
Het torso contains a particle accelerator that allows for a thin laser to be projected on the orb on her waist.
This orb then amplifies the laser with deathly properties.
Finally, the laser is further projected on the hollow abdomen, which contain a reflective surface, enlarging the laser to epic proportions.

She originates from outer space.

Dubhe is named after one of the stars of the Ursa Major constellation, pictured in the bottom right.
Her design is based on Deoxys, and could actually be mutation of a Deoxys.
Her design is also based on the first few steps of drawing a humanoid, namely, a stick figure.

... Or do you think she looks more like a Merak than a Dubhe?

The idea comes from the game Devil Survivor 2: Record Breaker, where the primary antagonists named are named after stars.
The so-called Septentriones are named after the Ursa Major stars.

I got interested in astrology ever since x.x;

And thus, I get to create a new Bestiary catagory... Uh... Any fancy words for "alien"?
I'll stick to Stellar for now ^w^;
