A/N: This is a "What If" story about Poison Ivy: What if Poison Ivy wanted a child, and Batman was the only one who could fulfill that need?
Planting the Seed
Part 1: Plants Have Urges, Too
"You do know that it takes two to produce a baby," Harley Quinnzell said to her current friend and sometimes lover. "And it has to be between a male and female?"
"Of course, I know that!" Poison Ivy snapped. "I've studied every biological reproduction dissertation there is."
"You and I are just not compatible in that way, and you are aware that every man who touches you dies. Face it, girlfriend, you're poison."
"If only there was a way, just once. That's all it will take. I want a child. Every plant and animal reproduces, why can't I?"
"And who would be the lucky fella?" Harley questioned, as if she didn't know.
Ivy looked up into the canopy of her hidden sanctuary. Its leafy umbrella was covered in night blooming flowers. She could easily name it, including its Latin name, but tonight, she simply observed its beauty and breathed in its scent. Her eyes became intensely focused as the scent drew in a variety of pollinators, one unexpectedly most of all caught her gaze.
'I should have realized. They are pollinators, too,' she thought. Then a plan began to form in her mind. 'Perhaps I can use its scent producing hormones to add to my own pheromones to draw in what I want.'
"You're scheming something," Harley noticed the look on Ivy's face.
"Whatever do you mean?"
"I know that look girlfriend. You're plotting something. We're the good girls, now. We're supposed to protect Gotham. This garden is a sanctuary for the children. It feeds people."
"I know that," Ivy said, "But, who's going to take over when I'm gone?"
"Hey . . . Don't talk like that . . . You're not dying, are you?" Harley sounded worried.
"Harley, all plants have a specific lifespan, just like everything else. Every plant is a descendant of the original plants of Eden. True there are some that can live a thousand years, but I'm not one of them. Gaia may have granted me the powers of the everlasting green, but eventually I need a fertile seed to plant. Now, be a good friend and pluck ten of those flowers, the ones the bats like. Though they are pesky creatures, they do come in handy."
Harley grumbled as she ascended the tree to reach the canopy. She snagged ten flowers then climbed back down and handed them to Ivy.
"Now, leave me alone for a while," Ivy said, as she headed to her lab. This was going to take a while.
Poison Ivy placed the flowers in a special vat that would extract the oils. She added a small amount of ambergris to make certain the scent didn't evaporate. She then took a syringe and filled it with her own blood. She slowly added it to the mixture, watching the color turn a rich green. Ivy needed to know if absorbed, her own body could reproduce the scent through her own pheromones. She needed to be careful. She didn't want to produce something that would attract the wrong kind of bat. Then it dawned on her on her. She needed matching blood to ensure only one kind of bat would be attracted to her, the human kind.
"Oh Harley," Ivy called out. "I need another favor."
