I've talked about Kurt before, I think, but this is probably a better official reference.
Team leader of The Underground, he's got a bit of an interesting moral compass. He can be arrogant and disrespectful, but his strong sense of pride includes advocating for racing cleanly, fair and square. Pretty much...a bully with standards. He ESPECIALLY dislikes overly emotional racers who aren't lucid behind the wheel, which doesn't mix well with our main character Tracey.
His good side and code of honor make him the kind of antagonist who may or may not end up playing a role in the protagonist's side when shit hits the fan...
