Here are the list of possible roles for this game. Not all roles may be used, but no roles outside of this list will be used. The number of players for each role is also not know (to anyone but me...).
(These are exact role PM's minus the fluff in all role PM's.)
Warios
Wario
You are Wario. You have hired several Wario Warewolves. Each Night you choose a player to murder-burgle. You may also choose to use your Mustache Powers and prevent a player from performing their Night action for that Night. If you die, your power to choose a player to murder-burgle will be given to a living Wario Warewolf of your choice. (The Mustache Powers will not be given, however.) (If the appointed player dies, it is transferred again, and so on.) You win when all non-Wario players are dead.
Wario Warewolf
You are a Wario Warewolf. That is, you are one of Wario's minions. Each Night you and your team murder-burgle a player chosen by Wario (or a Wario Warewolf if Wario dies). You win when all non-Wario players are dead.
Workers
Vanilla Worker
You are a Vanilla Worker. You do not have any special powers. You win with the Workers, and the Workers win when all Wario players are dead.
Underpaid Worker
You are an underpaid worker. Each Night you may choose to work overtime. You may not choose to work overtime two consecutive Nights. You earn more money, but you're also a larger target for the Wolves. Then again, everyone else earns more than you anyway. You may see a crime being commited while working overtime, but one of the burglers may see you, too... You win with the Workers, of course.
(You're basically an Insomniac.)
Mario
Woot! Mario's here to save the day! That's right, YOU are Mario! Couldn't you tell by your stupid clothes and Spanish French Indonesian Italian accent? Anyway, right now you're disguised so Wario doesn't sit on you. But he's also disguised so... Anyway, each Night you can choose to jump on a player. If they are a Goomba, they're dead. If they're a Koopa, they'll crawl in their shell and you can kick them around. If they're a Wario or one of his minions, they die and you move onto the next World. You can only jump once, though, because your butt will hurt afterwards. Still, you'll be cleared as a Worker and not a Wario player.
Oh, and you're with the Workers.
(You're basically a Vig.)
Pokey
You are a Pokey. Each Night you may choose to defend one player. (You may choose to defend yourself.) If that player is robbed by the Wario team, your Pokey Powers will prevent the kill. (Sadly, that player is still robbed.) You win with the Workers.
(You're basically a Guardian Angel or Doctor.)
