Wallflower - Batman: Arkham Knight (2015)

Pamela stirred from her slumber and squinted at the lone orchid on her nightstand. Conventional wisdom says a Gloriosa could never survive in such dry, frigid conditions, just as the doctors had predicted she herself would wither and die within a month of her admittance to Seattle General's intensive care unit.

It had been almost six, and the flower was in full bloom, while Pamela had never felt stronger or more in tune with the world around her.

The orchid had been a gift from her mentor Professor Jason Woodrue, the man who'd professed his love for her then left her to die from a toxic cocktail of phytohormones he'd forced her to ingest in the lab they shared.

Pamela's initial heartache seemed paltry in hindsight. She realised Woodrue's parting gift was far greater than even he could have imagined.

The orchid spoke to her now, ethereal whispers of a world beyond these sterile walls, of a higher purpose, a new life.

Pamela feigned sleep when the door opened and the handsome specialist approached the bed to check on her. She thrust out an arm, gripped the back of his neck with inhuman strength, and pulled him in close.

The man was powerless to resist as she planted a deadly kiss on his lips.

Timid wallflower, Pamela Isley, was no more. Poison Ivy had arrived.
