From down to the leader of a gang of street thugs, all the way up to.. well.. the Godfather of a prominent crime family. Whether great or small, create your own head of organized crime.
This character type is a bit underappreciated design-wise, but when you think about it, they come in all sorts that can make them have a unique look, from the Mafia, to the Russians, the Yakuza, the Triads, etc. You can even make them metahumans if you want, but I think it's more of a challenge to create your own normal human mastermind.
As for their motivation.. how 'bout we put them in a classic "if you want something done right, you gotta do it yourself" kind of pose, cocking a revolver, racking a pistol, pumping a shotgun, unsheathing or maybe sharpening a knife or a sword. If fisticuffs is their deal, cracking knuckles, taking off a coat, rolling up sleeves, putting on gloves, you get the idea.
Deadline is on March 21st.
