Author Note: This is a mostly AR version in the modern day focusing on, personally my favorite Batman character, Poison Ivy. There are going to be three relationships in this with a fourth being teased throughout. The main ones are Poison Ivy/Harley Quinn, Poison Ivy/Killer Croc, and Poison Ivy/The Riddler. Batman is not the focus of this fanfic since it is an AU. Well, thank you for reading this and I hope that you can forgive me any slips of fact 😊 but I really just hope you enjoy.

The Addiction of Poisonous Plants

Prologue

Pamela Isely loved plants. That was, simply put, a fact.

Ever since she was a young child she had felt that plants could be honest with her. People weren't honest, not like her father, he hadn't been an honest person when he had destroyed their family. Men weren't honest in general, the way that they only liked the pretty buds and would find that they had settled with the ones too shy to bloom properly. Well, it wasn't shyness that had stopped them from opening, it had been actions of aggression or neglect.

Plants could take the sun in the sky and through the power of photosynthesis give themselves energy.

Unlike what most psychotherapists would say, people were foolish enough to require a civilization to live and to be involved in their community. People had to find those who were able to make or harvest the food. People needed those who made houses and provided electricity. People needed others because the world wasn't able to be conquered alone.

Oh, how droll those doctors were.

Fortunately it wasn't all psychotherapists, it wasn't the young blonde that the red head felt herself attracted to.

Arkham Asylum had always been a game to Pamela. It was easy to manipulate the mind set of a foolish man and it was easy to deceive them or even to drive them to become completely mad. It was fun to see them obsess over her, that they wanted to give everything to her, that she could get anything she wanted whether they wanted to believe that or not.

Then she had come here.

Harleen Quinzel was an impressive specimen for someone from the animal kingdom. She was a fragile plant, but sometimes the most fragile of those plants were the most beautiful. She had taken a particular interest in Doctor Quinzel.

How many times she would get lost in those eyes which had such an unsettled expression in them. So many times had Pamela wanted to let her hands get lost in that blond hair, how she wanted to kiss those lips and make that good doctor forget everything she knew about psychology. Pamela, or rather Ivy, could teach her all the benefits to learning her psychology, the psychology of Poison Ivy should merit a few textbooks at least.

Of course, that was if her precious plants would allow for her to imbed her words on them. Men were always hungry for those things, greed and prestige. Those men would despicably destroy the plants from mother Gaea. How foolish they could be to disrespect that they used for life and sustenance.

She could show Doctor Quinzel how important plants are in the lives of those who were needlessly depressed, how the plants would twine around her heart and connect them.

Or perhaps she was being foolish again. If it hadn't been for her wanting to feel love and acceptance then she wouldn't be in here. She was happy with who she was, happier than she had ever been, but there wasn't a lot of sweet and tender greenery here in Arkham.

What there was was a lot of Doctor Quinzel and there was a lot of time to spend together.

A guard came up to her cell block and said the words that Ivy was so grateful to hear.

"Doctor Quinzel will see you now," they told her.

Ivy let a finger run over her lips. This doctor better watch her step because she was now being watched.

Pamela Isely was going to love this little plant the most.
