Founder Rumspringa is my favorite new term. Thanks for this.
I wonder how violent one of those would be. They were basically infants thrown into space with nothing but genetic instructions to eventually get back to where they came from. Odo and Laas are the only two yeeted offspring we know about, and they were generally neutral in manner towards humanoids, with Laas generally preferring to avoid them and not entirely agreeing with how dogmatic the Founders are.
I definitely would be more on the spec-ops team side of things myself, unless the Founder on Rumspringa was really jilted by humanoids and was just fucking 'em up for a laugh.
