SPOILERS FOR POTIONOMICS: BOSS FINN DLC
So far I learned about Boss Finn (Through Some of the rankings and the hang outs)....
Boss Finn used to have his friends (possibly a predatory/rowdy crew who valued winning and having everything over everyone), but when Sylvia won, his friends cut ties with him because he's deemed a failure. Finn didn't take it nicely and.. Well.. What remains of them still lingered.
When Sylvia met him again, Finn started out sombering over his failure, but then suspected Sylvia's intentions. Then he grew respect when he thought she's just sizing him up and started treating her like a teacher. In exchange, he gave her pep talks that'll help the card strategy (Which are very helpful in my experiences)...
Despite him still having the intimidating and scary attitude, Finn has a more sillier and dorky side of personality. Think of it as a college jock with a nerdy / snarky side. For example....
Boss Finn is a card collector, like a pokemon type of collector. He also likes valuable cards and prefers them to be encased in protective cases.
He also watches Reality TV and pulls so much commentary whenever he watches. Lately, when he and Sylvia became a thing, he stays quiet and wraps his arm around her. (AWWWW)
Boss Finn has electroception, which is an actual thing for Sharks. It helps predators detect natural, electric fields from those around them. For Finn, though, it helps him detect natural emotional strength, like fear and courage.
Boss Finn is very intelligent and clever to the point he spots scams, cons, and false products, as well as making his way through them without being a prime prey. For example, when Sylvia had to pay someone for "accidentally breaking their expensive phone," Finn saw the patterns of the cracks, figured the guy's manipulating Sylvia, and "persuaded" the guy to leave.
Finn's not the type to be called and referred to as a Mooch. If you're his friend, he'll treat you good!
According to him, Finn's species have a tradition of making jewelry, with the addition of their teeth as a way for connection. This is normal for shark since they lose their teeth and can grow them again. In Finn's case, one particular tooth belonged to a beloved grandmother, presumably his.
Why I said presumably? Well, according to Finn, his mom wasn't around when he's a young pup. Again - True to shark definition (Thanks Wild Kratts) because mother sharks do not have parental care and their pups are already capable of defending and hunting on their own. So in his case, he was a lone shark even when he's just very young, knowing he's already dangerous and meant to hunt.
When talking about Owl, Finn suspects that Owl is Sylvia's "secret weapon" since his dark magic patents seemed ineffective for her to back away and she received emotional strength from Owl instead. He suggests that to surpass Sylvia, he needed an owl much greater than Owl... With two functioning wings (ow!), a top hat and monocle, and laser talons (To threaten shoplifters). Also he can talk.
Despite having a snack on little people, Finn has a knack for defending little people, mainly his companions. He is on top of the food chain, knows his way through schemes and cons, and when he started redeeming, he makes sure Sylvia gets what she wants and doesn't undermine herself for other's failings or schemes.
This is why, at the end of his rank - Finn decided to be an advocate and guide to the public, keeping them safe from schemes and greedy snatchers since Rafta is still under development and the heroes and Town Guards are there to keep monsters away and collect materials.
