From a single suggestion (of a profession or a situation) players step forward one at a time to be the world's worst person to do that job or be in that situation.

If the suggestion is "Crossing Guard" some responses might be:
1) "Hey, I only lose one kid a week!"
2) "I'm not in it for the safety. I'm in it to log steps on my Fitbit."
3) "Sometimes you guard the crosswalk, and sometimes the crosswalk guards you, man."
4) "What do you mean I'm supposed to be wearing something under the vest?"
5) "NONE SHALL PASS!"

Your best protagonist is also the WORST person to drop into your story (for them at least). A story's job is to show a character changing in response to their circumstances—the more change go through, the more compelling the story. Ask yourself what kind of hero is least equipped to deal with the challenges you're going to throw at them, or most likely to suffer in the world of your story? Who has the furthest to go and the most to learn?

But we're often sheepish about making strong choices because it's a lot of pressure. So let's use World's Worst to give you permission to make bad, silly and ridiculous choices in the pursuit of strong, exciting, bold choices. Get loose, get brave, and open yourself up to surprising yourself with unexpectedly great/terrible ideas.

Here are 5 World's Worst main characters based on the Story Idea: "An FBI agent consults with a notorious serial killer in prison to track down another currently active serial killer."

1) I'm just a trainee! Why am I talking to a serial killer?! Seriously, I'm a super-newbie FBI agent!
2) I'm a female FBI agent who feels like she has to act tough to make it in a male-dominated field.
3) I'm also secretly a serial killer! Too Dexter?
4) My father was killed by a serial killer and now I can't eat breakfast cereal.
5) Or maybe my father was a lawman who was killed on the job (when I was a child) in the same kind of senseless violent act that I'm now trying to prevent.

Obviously not all of these ideas made it into the final version of the novel by Thomas Harris  :)

Here are 5 more World's Worst protagonists inspired by the Moral of the Story: "If you want to make yourself whole, solve the mystery, and catch the bad guy, you have to open yourself up to the darkness in the world and the darkness inside of you."

1) I'm trying to cover up my white trash roots and my fears of inadequacy so I can prove myself in the FBI.
2) I have a single terrifying memory of screaming lambs that haunts me. Will they ever be silent?!?!
3) In this world of killers, I don't know if I actually have what it takes to pull the trigger and kill another human being when push comes to shove.
4) I hate therapists! And therapy! I nearly strangled my last therapist to death.
5) I have a secret split personality who I have been keeping suppressed to prevent her from popping out and seeking chaotic vigilante justice.

Here are 5 more World's Worst main characters that are just WAY TOO MUCH (cliche, don't fit the genre, silly, etc.):

1) I'm secretly the daughter of a mysterious serial killer who was never caught.
2) I'm part of a failed FBI program to genetically engineer the perfect serial killer hunter, and this is my last chance to prove myself and avoid the termination of the program (and the termination of ME).
3) I've always dated guys in law enforcement, and there's NO WAY I would ever consider getting into a relationship with a serial killer. NEVER. GONNA. HAPPEN.
4) I had a pet lamb as a kid, and when my Pa had to put her down I swore that I would never open my heart up to that kind of pain ever again.
5) I am secretly a split personality, and it turns out at the end that I am both Agent Clarice Starling AND Dr. Hannibal Lector.
