The first character I created, the one this account is named after was a Selonian medic. After we started I learned that Male Selonians were essentially sex slaves and everyone joked that I was kidnapped from Selonia. So the first game I played him as timid, shy, and reserved. Unfortunately, that meant we didn't get anything done; so he allowed us to repeat that session.
In between sessions I saw the trailer for Central Intelligence and was inspired, so my backstory went like this: he was unwanted on Selonia, so he set off in to the galaxy to find his purpose elsewhere. But the only one who would take him in was an old farmer. for the next ten years he helped out, got stronger, and because he was so accident prone, trained with a medpac. Afterwards he got bored and hooked up with a group of mercenaries who taught him how to fight.
