Awazanak's Challenge

When you first start the game and get your first dragon, the Big Bad challenges you to what's ALLEGEDLY a spar, which is hopelessly outmatched and will kill the dragon that was just given to you. If you try to say you're not interested, he'll keep coercing you until he gets rid of the "No" option entirely.

(Not pictured: If you somehow actually win this fight - which is *technically* possible without hacking, but the chances are vanishingly slim - the game doesn't account for it and the cutscene after has the same dialog but glitchy graphics. The game wants you to lose.)
