The most recent! — 2015
After not drawing her a long while, I decided to give her design a big overhaul.
Simplified her suit, since it didn't need to be that complex.
Toyed with the design of her ship and weaponry.

New features!:
Beak like muzzle (To make her look less like a normal pony (also out of fear of Hasbro's lawyers)).
Two extra eyes on the sides of her face (better chance of seeing predators).
More tentacles (because why not).
Tail thingies (see above)
Three sets of ears (may change)
Tiny feet (inspired from a Scolipede picture I saw)

Also liked the idea of there being four major genders in her species (Oqumua); two kinds of males, two kinds of females.
Hermaphrodites and asexuals do exist but are rare, but not discriminated against.
Why?
Because Oqumua society has a more relaxed view of breeding. In that they just see it as something couples do when they're in the mood and alone. They don't really care if someone is gay/bi/demi/pan/asexual, so long it's consensual, no-ones a minor, and it's done in private it's fine by them.
