Bosco is an aloof Andrewsarchus that gets quite cagey when it comes to his past. When he arrives to Amber Isle, his goal is to be the best frisbee player the archipelago's ever seen. He’s extremely competitive, and thinks in absolutes: either he wins, or he doesn’t, he’s the best, or he’s the worst. That competitive mindset has gotten him in trouble when it comes to making friends, but Bosco's sense of fairness born from his tournament days in the Disc League doesn't just come from nowhere.
