Bruce Wayne (Batman)

Harley had managed to get a disguise and snuck into the party. She had managed to get some help rigging the entire place with modified knockout gas, using Ivy's pheromones and a chemical which caused black outs. With a set of micro-filters in her nose, she scoped out the room.

She noticed the kid in the corner eating cake and brooding like Batman, seeming to not enjoy himself. However, Brucie was moving from person to person greeting and chatting even as he occasionally danced with some of the ladies. Checking her watch which was the gas' timer and trigger, she moved till she could get into position to dance with the Billionaire.

"Care for a dance, handsome?" she asked Bruce, hoping he accepted as it would make it easier.

A charming smile and a nod was followed by a, "I would love a dance with a lovely lady as yourself, Ms...?"

"Ms. Hunt, Odelia Hunt. I must say just dancing at a party like this is like a dream or a fairy tale. Thank you for giving a young woman a thrill in her life."

"Well, glad to be of service. I like to know that I can help someone in any way."

Harley noticed a slight flash of her watch, signalling the gas was released. It moved quickly and quietly to cover the room, as one by one all of the guests fainted into sleep. The villain faked the same reaction to distract her target long enough for him to fall.

Lifting to carry him by having Wayne lean on her shoulders, she left for her hide out as she fled into the night.
