I'm pretty sure there was zero Nolan North. Just imagine if you had replaced Peter Dinklage with Nolan North. Like, if you're going to have one voice actor carry your entire shoehorned under-baked story, why would you not have that guy be Nolan North?
It's actually just Arial Black. I don't think it's perfect- but it seems close enough for me. Also, even though I know it originally stood for "Get Fucked, Boi" now I can't stop saying "Giant Fucking Bomb" when I look at it. So there's that.
