I prefer to work alone.
I'd make all the girls here spread their legs towards the population and stay with a fan behind them and shout in a megaphone "Drop 50 million dollars from air or I'll make their vaginal odors reach the city" and upon denial of request I'll turn on the fan and kill 6 gorillion people
Let's just imagine for a moment that ppl from this website met up IRL & formed a team of murderers. How do you imagine such a team would come about, how big would the team be, what members would it consist of, would is disintegrate either from infighting or sth else, how would leadership & decision making be handled, how would task delegation be handled, what team roles would exist, would we get caught & if so how many murders would we get away w/ before that happened, where would the team founding meeting take place, where would we primarily operate, would we form connections to other villains like terrorists & mafia, would we actually create snuff films, etc.
Just to get it out of the way, If people here met in person that doesn't mean they would team up and become mercenaries.
However if they would do the mercenary thing. The only real way of doing this, is to have pay on commission. The jobs would have to make money, and the job would go to the mercenary who would bid the lowest for the Job.
Reaper says she'd only work alone, unless maybe you smack her across the face with 100 grand.
There is no guarantee of never getting caught. And yes, terrorists and Mafia or some kind of organized crime would really be the main source of income.
Other mercenary groups wouldn't have a problem lynching the SC mercenaries, since we'd be stepping on their toes, so it would be a good idea to wipe them out just for knowing who we are. The only secure way to live like that, is if we had force fields with the ability to teleport, or if we were like the Flash. Otherwise we'd just have to watch our backs for the remainder of our time.
