DAVID CAIN

One of the world's premier assassins, David Cain's history with Bruce Wayne predates Wayne's decision to don the cape and cowl. He trained young Wayne as a member of the League of Assassins and taught him his most deadly techniques. These maneuvers were so deadly that Batman still refuses to use them to this day. Cain also trained his daughter, Cassandra Cain, by teaching her everything he knew and avoiding teaching her anything that may interfere with her training like the ability to read and write.

David Cain may have debuted in the 1990s, but he is an integral part of Bruce Wayne's life and the formation of Batman. With ties to the League of Assassians and Bruce Wayne before he became Batman, it seems almost impossible to explore the early years of Batman without David Cain.

Chances: 40 percent

Why: While we would love David Cain to be a main villian, his history with Batman may be to unfamilair. We hope there is at least an Easter Egg involving the character.

DEADSHOT

An assassin who already made his game debut in "Arkham City," Deadshot is one of the deadliest marksmen in the D.C. Universe. Making his debut in the 1950s, Deadshot was created by the legendary Bob Kane, and was introduced as a crimefighter attempting to take Batman's place. Once his true intentions were discovered, he was placed in jail. He soon escaped and became a gun for hire.

Because Deadshot is one of Batman's oldest villains and a Kane original, it is difficult to believe that "Arkham Origins" will include assassins and leave the man who "never misses" out of the game. Deadshot is also already a part of the Arkham Universe, which increases the chances that he will be included in the game. Besides, Deadshot is a huge part of the CW television series "Arrow," which leads us to believe that Deadshot will have Batman in his sights in "Arkham Origins."

Chances: 80 percent

Why: As one of Batman's oldest villains, it is almost certain that Deadshot will appear at some point in an "Arkham" game.

TALIA AL GHUL

We expect Talia al Ghul, another character in the Arkham Universe, to be an integral part of "Arkham Origins." Talia has long been believed to be Batman's true love. Her love for the Dark Knight and her loyalty to her father has often caused her to be at odds with her own emotions. Also, wherever Talia goes, Bane is sure to follow. We have yet to experience a true battle between the Dark Knight and the man who broke the back of the bat. Talia is an expert fighter and the heir to the League of Assassins.

Her father believes Batman to be the true heir to his throne and wants him to marry his daughter. While Talia's love is strong, her loyalty to her father has proven stronger. Talia and Bruce Wayne even share a son. Could her loyalty to her father force her to kill Batman for not accepting Ra's offer to take over the League of Assassin's?

Chances: 90 percent

Why: Talia is the heir to the League of Assassins and already a part of the Arkham canon.

SUICIDE SQUAD

Also known as "Task Force X," the Suicide Squad is a group of villains-turned-government-operatives under the command of Rick Flag and Amanda Waller. The squad's missions normally result in the death or torture of their target. Deadshot, another name on our list, has often been a member of the team.

The Suicide Squad has had many incarnations and always is in conflict with Batman one way or another. Because Waller knows Batman's true identity, she uses this to her advantage to attack the Caped Crusader. With Batman gone, the Suicide Squad could complete its own sadistic brand of terrorism without opposition. Could Waller's vendetta against the Bat bring the group into "Arkham Origins"?

Chances: 40 percent

Why: While the Suicide Squad has a colorful history, there may be too many versions and members to pin down for the game.

LEAGUE OF ASSASSINS

The League of Assassins is the legendary society responsible for much of Bruce Wayne's martial arts training. Their leader, Ra's al Ghul, has been obsessed with Batman and even gave him the moniker "The World's Greatest Detective." The league has been a thorn in Batman's cape for a long time. Seeing how "Arkham Origins" focuses on assassins attempting to kill the Batman, it is almost a given that the League will make an appearance.

While the League would make great enemies for Batman to take out and display his combat moves on, we are thinking bigger picture. We believe that Ra's al Ghul is the man behind this attack on Batman and that possibly the assassins are competing for the throne of the League of Assassins and the hand of Talia al Ghul.

Chances: 90 percent

Why: You cannot have a Batman game featuring assassins without the League. Plus, Ra's has debuted in the Arkham canon already.
