Defining Daecon starts out with Daecon flirting his way into danger, if that counts for anything....
which one of your OCs is most likely to seriously injure someone while attempting self defense?
When Daecon was fighting his way out of that danger that he'd flirted himself into he broke one guy's legs with a sweeping kick and destroyed another's larynx with a throat punch... and that was before his powers started developing
Who is most likely to dive into an other-worldly adventure on a whim without making a plan?
...and that whole sequence of events tossed Daecon into a world of shapeshifters, magic, and murder that he didn't even know existed, so he certainly didn't plan for it...
Daecon is a big Harry Potter nerd. Finding out he had magic capabilities was almost as good as getting a letter from Hogwarts in his mind. Yes, he knows how much of a TERF bitch JK Rowling is, but he read the books long before she showed how terrible she was.
Daecon was raised as an orphan so he'd have sold his mom for belly button lint. Except, it turned out he had no mom, so I guess he'd have to find his own belly button lint.
Daecon rarely ever had a second date (he is also a Pokemon nerd and used the "Gotta Catch 'Em All" slogan as a personal challenge when it comes to dating), and so with him, things would get awkward when he finished and then asked 'Why are you still here?"
I've got to point out that in his defense he grows exponentially as a person as the story progresses...
