Just for the record. 1 died early on. 2 survived up until they escaped and was killed by guards. 3 survived and is still at large. 4 & 5 have stuck together and have been killed by Shirley. 6, 7, and 8 have been killed by Jack. 9 & 10  are still causing havoc in the world and need to be stopped. King has fought Jack but escaped. Ace went missing after he escaped with Jack and is presumed dead. Lastly, Joker is the worst of them all and murders more and more people every day, he is far to powerful for Jack to take on alone. 

So all and all out of the 16 there are only a few left alive just to make things easier:

3
9
10
Jack
Queen
King
Joker
