Just like in Part One I list DC Comics assassins who we could be up against in the up coming Arkham Origins and whose out to kill Batman:
Name: Constantine Drakon
Skills: Master martial artist whose reputation goes without saying is among the best and he's known for throwing so fast no one can even see it coming, as well as catching projectiles aka batarangs and.... maybe arrows.
Why: Another Green Arrow villain hint here and being paid a large sum to kill Batman is a bonus for our assassin Constantine he'll be another one to possibly watch out for.
Name: Unknown better known as Prometheus
Skills: Where to begin...
.: The costume is made of a lightweight and durable material, which is intertwined with synaptic relays to increase their formidable fighting prowess and covered with microscopic nanobites to affect the opponent's brain. The armor is also able to fly through the manipulation of magnetic forces and generate force fields
And that's the suit he uses to be extra bad ass although he is still a skilled armed and unarmed combatnant, Intimidation, expert marksman, and a genius i give up on the game if he's in it.
Why: We all know Black Mask yes? He's a genius who knows gathering all these assassins could get ugly so I propose that he makes Prometheus his bodyguard in case things go sour with the assassins or Batman even, you read the skills and the suit powers right? Wouldn't you want that to be at your side defending you?
Name: Anatoli Knyazev aka KGBeast
Skills: With his hand cut off by his own... other hand he'd make for a great early boss for the Dark Knight and his gun arm and master marksmanship is a deadly combo I'll have to keep my trigger fingers ready to dodge his bullets.
Why: Black Mask is going to like Anatoli's style of self mutilation to survive and is going to employ him with the job of taking out the bat due to his experience with demolitions and being a KGB agent to boot.. that's a lethal combo to employ and that's what Black Mask is going to need on his side.
Name: Talia Al Ghul
Skills: Being a more than capable martial artist, weapons expert, and beautiful to boot Talia is great to include as she also has the entire league of assassins inf ninja squad at her command.
Why: Black Mask would have either done business with or is being played by Rhas Al Ghul because he would use Talia to further his own goals of destroying Gotham. Let's not forget the foreshadowing to a certain awesome son that Batman and Talia could have mentioned in a future Arkham game.
