Actually, she's only one of them but I'm sure you already knew that. The latest in the rotation of available champions for League of Legends is Caitlyn. She has all kinds of abilities that players will find useful:
Piltover Peacemaker - a penetrating shot that can deal damage to multiple enemies
Yordle Snap - a trap that immobilizes and deals damage
90 Caliber Net - slows the target and knocks Caitlyn back
Ace in the Hole (Ultimate) - massive damage to single target
Headshot (Passive) - every 8 attacks yield 150% damage to a champion or 250% damage to a minion
Below are a few screens and even a video that show Caitlyn in action. As always, head over to the official site to check out the game.
Caitlyn, the Sheriff of Piltover
One of the reasons Piltover is known as the City of Progress is because it has an extraordinarily low crime rate. This hasn't always been the case; brigands and thieves of all sorts used to find the city-state an ideal mark for plunder, primarily due to the valuable resources it imports to fuel its techmaturgical research. Some even theorize that it would have fallen long ago to the chaos of organized crime if not for Caitlyn, the Sheriff of Piltover. Born the daughter of a wealthy statesman and a pioneering hextech researcher, Caitlyn discovered her natural gift for investigation when, at age 14, her father was assaulted and robbed on his way home. She snuck out of her house that night with her father's rifle and tracked down the muggers from the crime scene. At first, her parents did their best to discourage her from such risky hobbies, but she was incorrigible. Wishing to protect her daughter
in the only way she knew how, Caitlyn's mother began outfitting her with techmaturgical devices tailored to her sleuthing needs.
Caitlyn quickly gained notoriety, both because she was singlehandedly defeating crime in Piltover and also because she soon developed into a ravishing beauty. She never backed down from a case or a challenge, and she was one of the sharpest shots in the city-state. Her services were soon requested by Demacia to help track down a mysterious outlaw who had begun committing high-profile heists. The bandit, who always left a card with an ornate "C" at the scene of the crime, became Caitlyn's arch-nemesis. To this day, Caitlyn still searches for this cat burglar, and the chase has led her all across Valoran. She has joined the League to hone her skills and gain the influence necessary to track down the only quarry that has managed to evade her.
"Go ahead, run. I'll give you a five minute head start." -Caitlyn, from her book Willing Apprehension
Piltover Peacemaker: Caitlyn revs up her rifle for 1 second to unleash a penetrating shot which deals physical damage (deals less damage to subsequent targets).
Yordle Snap Trap: Caitlyn sets a trap to reveal sneaky yordles. When sprung, the trap immobilizes the champion and deals magic damage over 1.5 seconds.
90 Caliber Net: Caitlyn fires a heavy net to slow her target. The recoil knocks Caitlyn back.
Ace in the Hole (Ultimate): Caitlyn takes time to line up the perfect shot, dealing massive damage to a single target at a huge range. Enemy champions can intercept the bullet for their ally.
Headshot (Passive): Every 8 attacks (attacks while in brush count as 2), Caitlyn will fire a headshot, dealing either 150% damage to a champion or 250% damage to a minion.
