New to the game where dis?

Im trying to build a character for a potential game (introduced my groups GM to starfinder and he seemed into it so im getting ready) and one thing i usually do is write a story alongside the character and the things they do. Im building an evolutionist ramiyel and i want to have her story be that she's publicly a dangerous game hunter.

Traveling the galaxy looking for the biggest and deadliest creatures on planets so she can take them down, but in private she's hunting these creatures to further her adaptations.

I do realize I'm ripping off things like the zerg, 40k's tyranids, xenomorphs/predators, ect, ect. But in all fairness who hasn't

My biggest blockages are finding a fitting theme and homeworld so if there are any of the old guard or a lorehound or two here I'd love the assist thank you in advance and i also apologize if this is stupid
