It was the next day, and both (Y/N) and Ivy had gotten their bearings. Details had been gathered around the ice man, who the media nicknamed 'Mr Freeze', a name which seem to get straight to the point. He was immediately locked in a psychiatric hospital named, 'Arkham Asylum' which seemed more like a prison than somewhere you would go for help. During the day, (Y/N) did his best to master his abilities. Through focusing and sheer force of will, (Y/N) could manipulate the biology of his own body, the more toxic he wanted his body to be, the more green it would become. While (Y/N) was in awe of this ability, he decided that using toxins was not really his thing. Pamela was all about the subtle approach, so (Y/N) showed her the ability and how to achieve it.

Speaking of Pamela, she seemed more and more decided on the use of the Poison Ivy moniker. She would sometimes correct (Y/N) if he were to use her 'human name'. It was understandable, at this point they were more than human, why conform to their rules? 

When it came to fighting, (Y/N) found he took to a more weapon like style than muscles and toxins. Over the course of an hour he mastered the thorn projectiles, properly size them, accuracy and push them to their absolute limit. It appears no matter how big (Y/N) made them, or how many he threw, he could simply create more and more thorns. The more (Y/N) surrounded himself with the green, the more of his abilities seemed to come to the surface. A command of the plant life, with a mere wave of his hand (Y/N) could tell the plant life to attack any target of his choosing, and make it fatal if needed. 

What (Y/N) found fascination was how the green would actually weaponise itself in order to protect its master. As he brought more plants to the surface, some wrapped itself around his right wrist, and with a flick of that wrist;

(Yes the image is a recreation of the sword from Adventure Time, it can be the design of any sword of your choice this is just for simplicity)

The vines flicked out to create a sword, as sharp as steel. (Y/N) waved the sword around quickly and it seemed as lite as a feather. Though the blade itself could most likely cut boulders in half. It was amazing what the Green could accomplish when commanded to. With another forceful flick of his wrist, the blade instantly retreated and wrapped itself around (Y/N)'s wrist yet again. Now it was simply time for a test of his abilities. 

Journeying in the mucky streets of Gotham City, it wasn't hard to find a set of guinea pigs. Troublemakers, harassers, the lesser of society who would go unnoticed if they were to go missing. 

(Y/N) made sure to ruffle up his appearance as too not to be recognised by the general public. Both he and Ivy had made the front page of the 'Gotham Globe' named as 'Dazzling Mystery Guests'. Although many of the interviews were released more to Ivy than himself. While going out, (Y/N) made sure to make his hair messy, and throw on an old shirt which had been left behind by the previous occupiers. 

Keeping up the act as a normal citizen was almost impossible now, the screaming of the Green could be heard all around him, beneath his dam feet and (Y/N) had to ignore it all. Although it only took a few minutes of walking around the streets to garner the attention of two unlucky souls who trailed behind (Y/N) for a few blocks. Taking a turn into an alleyway which would be a dead end within a few meters (Y/N) held a devilish smirk. 

He heard the unmistakable click a pocket knife and a light chuckle from the other. 

"Say buddy, you don't happen to know the time?" one of the men asked, it was clear by his tone of voice he was cocky and over-confident. 

(Y/N) slowly turned around, hands in his pockets as if he hadn't a care in the world. "No I'm sorry, I don't wear watches. Their so restricting wouldn't you agree?" he asked pulling his hands out of is pockets but holding a smirk. 

"Well, last time I checked" the armed thug spoke up and walked forward raising the blade pointing towards his 'victim'. "It was about time you hand over everything you got" he added as his friend held a similar grin. 

"Unfortunately I don't seem to have much of value on my person" (Y/N) said as a mere look caused the Green to act. Moving up, and quietly locking the metal gate that they walked through to get to the alleyway. "Unless of course" he held up his right wrist and flicked his wrist, "Something like this?" 

The faces of the thugs were instantly lit up with fear and confusion as the grass blade scrapped against the ground. The armed thug's arm began to shake as his eyes scanned all around almost looking for something, an exit route. 

"What the hell?!" the unarmed thug cried as he jumped back, a few steps behind his knife wielding friend. 

"He's one go them" the knife wielder called, spit being thrown from his mouth. "One of them freaks you see on the news, like that Two Face guy!" he came closer, although fear was visible across his body. 

"How rude" (Y/N) calmly stated with a slight tilt of the head. "I am far from a freak" with a quick swat of the blade, the knife was forced out of the thugs hand and clanged against the floor, the thug's grip being weak. Using his left hand, (Y/N) slowly made a fist and mould from the bricks swallowed the knife. "I am the embodiment of the Green" he finished, out reaching his arms. 

"Screw you prick" the lead thug called, charging at (Y/N) with sweat beaming down his body. Using his left hand, (Y/N) fired off three small, yet deadly thorns aimed for the man's right leg. All three hit their mark, causing the thug to wince, blood flow from the wounds and his speed to decrease. As the thug continued to approach, (Y/N) easily side stepped the sloppy charge, and slashed down the man's back, causing a large wound and blood to pour from it. The thug falling to the ground, still conscious but barley able to move. 

The second thug saw this, and his body still shook and did what any logical person would, run. Running back to the gate, he did his best to pull it open, through the now thick layer of green. The thug clawed and tore the vines away, but with each tear they seemed to miraculously grow back. The thug looked back, seeing his adversary approaching him slowly. 

"Come on then" the thug said raising his fists ready for a fight. "You wanna go?" he asked, throwing a right hook which (Y/N) weaved out of the way. The thug threw dozen of punches, each sluggish to which (Y/N) avoided. They weren't fighters, these weaklings preyed off fear to win. One punch actually managed to hit (Y/N) in the chest, sending the plant hybrid staggering back, although it didn't hurt too much, it did cause the confidence to falter. 

"I've lost my interest" (Y/N) scoffed, dashing in sword at the ready. Two clean slashes at the thugs knees, causing him to drop to the floor. Getting behind the thug, (Y/N) used a great deal of force to kick him to the ground, both thugs close to another, although still alive. (Y/N) flicked his wrist once again, causing the blade to withdraw. "Don't worry I'm not going to kill you" he spoke softly turning to leave as the vines on the gate withdrew for their master as he fixed his collar. "I'll let them handle that" he said with a snap of his fingers. Instantly, the ground beneath the laying thugs split, vines and other plant life suddenly covering them, wrapping around them and absorbing them into the ground. The thugs couldn't scream, as grass and roots invaded their mouths. (Y/N) only smiled as he made his way to the hideout, "They'll make such good fertiliser" he spoke to himself. 

Arriving back at the Turkish Baths, (Y/N) saw that Bane was guarding the outside. Simply standing there like the mindless brute he was, looking forward into empty space with the only sound being his heavy breath. Walking up the entrance, (Y/N) looked at Bane and noticed he was holding a familiar outfit under his arms. 

"GGRRRRR" Bane growled handing the outfit to (Y/N), inspecting it (Y/N) noticed it was the outfit he had worn the night before as Thorn, although it was now cleaned. 

(Y/N) took the outfit and looked at with a raised eyebrow. "My guess is that Ivy wishes me to wear it?" he asked less than impressed trying to get answers out of the brute. Who only nodded in return as (Y/N) opened the creaking gate and went inside. Entering the Turkish Baths, (Y/N) found that the small section by the entrance had been walled off by a thick layer of hanging vines from the ceiling. Taking this as privacy, (Y/N) quickly discarded the scruffy outfit and changed into his nature attire. Moving deep into the hideout, (Y/N) could see that it was coming along quite nicely, the plants had been injected with small amounts of venom samples, and now they could 'talk' with nature itself, they could get the doses right, plants were beginning to mutate. 

Walking into the far back section of the hideout, it was a paradise. The 'on the water' section was now garnered with lily pads, seeming to be a mixture between a pond and pool, and the plants in the room flourished. All sorts of colours weaved through the mutating plants, with (Y/N)'s eyes landing on what appeared to be a flytrap bed, which was opened and weaved back and fourth. 

(Y/N) was slightly confused as Poison Ivy was nowhere in sight, although his eyes quickly closed as that addicting scent invaded his nostrils. He recognised it, the dust, it smelt like every lush scent of the jungle had been rolled into one honey like substance which caused him to relax. (Y/N) breathed out, his body becoming relaxed and slump, with the memory of the previous nights kiss coming to mind. 

"Sorry for the delay" the smooth voice of Ivy called out from the side and (Y/N) turned to face her and was caught off guard. It was clear that while in the comforts of the hideout, Ivy had embraced her nature side more and more as (Y/N) starred in awe.

Her skin had the slightest tint of green to it, while her outfit was completely made out of leafs and the green itself. Her smooth legs were on show for only (Y/N)'s eyes, her outfit hugged her mouth watering figure and seemed the slightest breeze would tear it off. 

"I was simply testing my next dose of pheromone dust for our next encounter with Batface and Birdbrain" she remarked as she studied (Y/N) current state, holding a devilish smirk as (Y/N) seemed bewitched at the sight of her. 

"That's-" he shook his head to try and clear it. "-Completely fine, I think we should discuss our plan of attack" he said as he stepped around the room, doing his best to keep eye contact. (Y/N) knew what she was doing, the kiss was simply the catalyst of what was to come as they could feel the desire for one another, it was all about who would act on them first. 

"The walking popsicle is locked at that Arkham place. I can get us in, but what next?" she said, taking off her pheromone pouch and placing it down on a nearby plant covered table. "I don't necessarily want him here for long" she scoffed thinking at what those sub-zero temperatures would do for the Green. 

"He was stealing diamonds" (Y/N) declared deep in thought. "He must have a plan to use them in some capacity, so we play into his plan" he said as his eyes wondered Ivy's body once again for a quick moment. "The popsicle, Bane and I can break them physically, but you my pretty little rose" he spoke moving towards her, "Can make them break each other" he finished as looked out onto the pond and flytrap bed. 

"And after that?" she asked, intrigued and amused at his plan. 

"We turn on the frost man and take Gotham ourselves. And then the world" he finished breathing a sigh. "Like dominos, everything shall fall into place" he concluded as Ivy walked over to him elegantly. 

"And how shall we take over Gotham?" she whispered, her face coming close to his. 

"I believe Bruce Wayne has some connections. We control him, we control his company which we can use to our advantage" he whispered as he had thought of everything. All they needed was to enact their plan. 

"Good" she whispered, bringing her lips closer to his. "Good" she soothed as both hybrids closed their eyes giving into the lust. 

Although Ivy surprised (Y/N), by breaking away from him and using her strength to push him back and him falling into the pond/pool behind him. The Green moving out of the way for their master leaving the area clear. (Y/N) pushed himself to the surface of the water, wiping droplets from his eyes, looking confusingly up at Ivy as she entered the water slowly. With each elegant step, deeper in, the leafs slowly began to dissipate, each breath taking curve slowly revealed. Ivy's eyes were locked onto his, with her biting her lower adding to her aura of sexual nature. (Y/N) himself strode through the water, towards Ivy as their eyes scanned one another. Her full lush breasts were eventually fully revealed, them bouncing and swaying with every step. 

Soon enough, their lips eventually met, although this was different from before. (Y/N) could feel himself slowly drifting into the emotion of lust, his hands moving to wrap around Ivy's goddess like body. His right hand moving downwards, and gripping her smooth ass, the action causing Ivy to moan against the kiss. 

Ivy saw this as her chance, and opened her own mouth allowing their tongues to do battle. (Y/N) stifled against this sensation, her mere salvia tasing of sweet nectar, it moving into his own mouth and causing his penis to harden down below. 

With his body filling with desire, (Y/N) moved push Ivy's back against the edge of the pond as their tongues continued to do battle. Needing to break for air, the two hybrids separated from the kiss. 

Two adults, mutated by nature, were finding comfort with one another 

(Y/N) moved his mouth from Ivy's red filled lips, and began moving downwards. Peppering kisses from her jaw, down to her neck. Kissing and sucking every inch of skin his mouth would allow him to touch. Ivy's left hand moved up to cup the back of (Y/N)'s head to keep him place. 

"M-more" she moaned as her partner found the sweet spot to make Ivy sing. Her flesh soon beginning to show marks of desire along her neck. Ivy managed to hold down her moans as her right hand moved to the jacket (Y/N) was wearing, "You're still dressed" she soothed as she started to pull apart his outfit. 

Soon enough (Y/N) was left completely naked, Ivy could see his hardened length under neath water and wrapped her right leg around his waist and settled herself. Both once again locked eyes as (Y/N) slowly inserted himself into her waiting womanhood. The moment the first inch was fully inserted, both hybrids threw their heads back in pure bliss. Every inch that slowly inched in, cause ripples of pleasure to shoot throughout both bodies causing Ivy to become a moaning mess, and (Y/N) bit the inside of his lower lip to silence himself. 

Eventually (Y/N) had eased all 8 inches to the Goddess of Green, both began to pant as they got accustomed to one another. Ivy rested her head onto (Y/N)'s shoulders while (Y/N) attempted to control his breathing. It seemed to the two were made for one another, as (Y/N) fit her like a glove, her folds gripping him tightly sending pleasure coursing through him, while also holding the slightest element of pain which felt incredible. 

A small nod from Ivy, told (Y/N) that he could begin moving, with him pulling part of his member out only to thrust back in. Causing Ivy to  lean her head back and looking up at the ceiling. As (Y/N) began to repeat the action, each thrust causing him to grunt, as he would pull out, Ivy's whole body would simply pull him back in. Ivy began releasing moans under her breath, (Y/N) needing to release the passion bubbling up inside, renewed his assault on her neck. 

Both remained like that more minutes, the persona of a femme fatale was coming underdone as Ivy tightened her inner muscles around (Y/N)'s manhood as she wrapped her arms around his neck and brought him in for a sneering kiss. 

(Y/N) could feel himself tiring, and his member twitching as his end was nearing. Although (Y/N) continued to thrust into Ivy, not wanting to be the one to lose this game. As their tongues did battle, (Y/N) moved one of his hands to cup her left breast. Causing a silent moan to come from Ivy's mouth in the kiss, as he pinched at the hardened nipple which had the desired result. 

Ivy's inner muscles tightened around his length sending her over the edge. Wrapping her other leg around his waist as she hung on for deer life. Ivy separated from the kiss and allowed moans to flow through her mouth. 

The erotic sounds coming fromIvy, and amazing tightening sensation slowly enveloping his member (Y/N) could feel himself twitch as his end was approaching. 

"I'm-" he choked into her ear, as he breathing rapidly increased from his nose. "I'm close" he managed to get out.

Placing her right hand on his cheek Ivy brought them face to face, "Inside, safe" she managed to whisper as both mouths collided in bliss, indicating that today was a safe day. (Y/N) buried himself fully within Ivy, unloading wave after wave of cum within her. Grunting out loud through grit teeth, as he attempted to push himself as deep as he could. Ivy let go, and leaned her back onto the edge of the pond, as (Y/N) soo began to finishing. 

Both remained joint at the hip for minutes, both catching their breaths while they looked at one another realising at what had been done. Both mouths dove at one another again, (Y/N) carrying her out of the pond towards the large flower bed. Ready to engage in a night filled with passion.
