Mishka is an organic machine, artificial intelligence. It is designed to be whatever you want it to be. It can take any form, any gender, and any size at will, and is programmed to do or act like anything anyone might desire. Think of it as a slave to your whims.
Mishka generally takes the form of a short, lithe leopard with silvery-white fur and light grey spots, red eyes, and long, green 'hair' made of optic cables. Its 'skin' also forms into its clothing, but it is usually naked.
Even while its body changes, its voice stays the same. Quiet, with a light Russian accent, only changing in pitch depending on its form.
Mikhail is Mishka. Mishka only goes by the name 'Mikhail' when its in one specific form. That form is a rather large King Cobra, 28 feet in length from nose to tailtip. As Mishka is designed to help people, it doesn't have any poison, but it still has the hollow, needle-like fangs of a cobra. Mikhail is always going to be 'male', with a large, bluish-silver cock about eight inches wide at the base, tapering down about twenty six inches to a thin, blunted tip for ease of access. The length, like the rest of Mishka, is flexible and able to change size at will.
(Honestly, I'm a REALLY open minded person so I'll do anything... Except for scat. I mean come on, that's just... Ugh...)
