I'm not usually a bit fan fiction kind of guy but, I was sketching around and this little gal popped out.

I've put her into the Guardians of the Galaxy universe (that's odd to write) as a foil for Rocket. The first sketches were more like Rocket, quite animalistic but, she became more anthro and her story changed.

So far, she was a human transformed into this form by the same mad scientist that made Rocket (I mean, he MUST be from Earth as he made a sentient, talkative raccoon...). Between the change in her brain chemistry to allow her to use a squirrel's body and the shock of transformation, she's a bit mad. Her anger at the transformation has changed the squirrel's 'flight' reflex to a fight reflex and even Rocket has to keep her from shooting things up on a regular basis.

Not fully inspired by Battu but, a bit, I must admit. Battu is so fun.

Also, a scramjet is a real thing and a good play on Rocket Raccoon if I do say so myself...
