Street Fighter Beta. Salary: About three ounces of scrap food per fight 

You always liked fighting. It was only when you were twenty-eight and got sacked from your job at the convenience store that you considered pursuing it professionally. Unfortunately, you got KO'd your first three fights, didn't make rent, and now you're only fighting the dog for room on your parents' couch.

The Human Speedbag. Salary: $35,000 (on a good year) 

You got into the game a little late, and a little light (featherweight, to be exact). You fight on the local circuit, but you're not very good. You earn a living, but after a few years of dating, your significant other makes you quit and take a more stable job so you can help support a family.

The Amazing Johnny Average. Salary: $75,000 

It's crazy. You win every other fight, without fail. You've come close to beating some great and famous fighters, but you've only ever nicked a couple top-tier competitors. You also lost to the Human Speedbag once. Super Embarrassing.

The Human Jawbreaker. Salary: $80,000 

They love you. Your charisma carried you to the top, where you had the honor of being KO'd by the champ himself. Unfortunately, when you woke up, you were ten percent less coordinated, so it was sort of downhill from there.

Please Don't Hurt Me! Salary: $200,000+ 

No offense sir, but we really fear you. We mean...respect you. You took out the champ, claimed the belt, and more importantly, landed that Subway sponsorship. You keep winning, they keep paying. It's all good.
