Let's Get Ready to Rumble

You enter the ring as ready to fight as you've ever been. You're a strong young man of short, vibrantly red hair and a physical build that speaks as much to strength as it does to speed. You're not the strongest, smartest, or the fastest competitor here, but you have all three traits in equal measure. You know that the key to victory is leveraging your strengths against your opponents' weaknesses.

Given the stripping clause, every fighter is required to enter the ring in similar attire. The standard uniform is a plain white jockstrap, and a colored ankle-bracelet so that the audience can tell you apart from your opponent in a scuffle. Your own anklet is red; a color of boldness!

Your opponent jumps the ropes on the opposite side of the ring. This guy is pretty weak, all things considered. No major muscle-mass, a pretty average build. He's more the type of guy to play video games than to fight, but you know better than to underestimate him. His name is Ryan. His white jockstrap matches your own, and a blue ankle-bracelet adorns his left foot.

He knows who you are. He knows that you're the favorite to win out of all the newcomers. That means that he's got something to prove.
