i realised just now stellata would be the one to be in an escape vehicle, and when they start getting shot at, ask where the jet booster is. "what do you mean there isn't a jet booster!?"
probably having had more exposure to weird cars than normal ones.
driver: "we do have priorities - safety first!" [several shots puncture the roof] stellata: "we'd be a lot safer with the laser cannons and jet boosters!"
Speech note: Jessie uses similies like "more [adjective] than a [alien] in [situation]."
"That's sadder'n a wet Martian." "Funnier than a Piscene doing a two-step."
I'm giving her a kind of stereotypical "rural America" speech pattern, but an air of well-traveled galactic experience. And pumping her general enthusiasm about life up toward Pinkie Pie.
So, I think that Sworn to uphold Galactic Law and Daredevil and Dashing probably sufficiently cover the "kicking ass for the good of all" end of her character.
Her Omega aspect can be something totally different that fleshes out her character.
