The Harlequin

The Harlequin, called Quin by her friends, was an acrobat and aerialist with Cirque du Soleil in Las Vegas. During a performance, her rig snapped and she fell thirty feet to the stage - and bounced, her body permanently transformed to a rubber-like substance. Her skin is the texture of latex, her bones the density of hard rubber, and she is almost immune to direct kinetic damage; she will bend and bounce back under an impact, whether from a fall or bullets or a hit from Astra, which would injure or kill a normal person.

Her transformation makes her a lot stronger than the average person of her trim athletic build, and she can run faster by "bouncing" along. She is a trained martial artist and marksman (although she doesn't normally use guns), and is the Sentinels' field medic as well as its publicity and marketing coordinator, which she does with Alex Chandler.
