"Well, this is interesting."

"How so?"

"The symbiote has also created new cards for her to use."

"Great. Just what we needed. Her cards getting corrupted as well."

"Let's just focus on Aki, alright? Besides, you're the one who's worried about the timeline getting corrupted."

"Fine…"

Aki, now Nightshade, reveled in her new strength. Her body was flawless, and she was brimming with energy. She tested out her newest appendages, the six tentacles attached to her head, and discovered they could stretch to several times her own length, were prehensile, and very flexible. She also experimented with the sleek black blade that could extend and contract from her right wrist. Aki enjoyed the mysterious second tongue she now possessed, and knew that the tiny black heart on her face that marked her lips hid a secret seam, behind which was a mouth full of fangs.

Enjoying yourself?

The symbiote interrupted Aki's fun, bringing her back to reality.

This is glorious! Do all of your hosts feel like this?

It gets better, my new companion! Let us instruct you in the art of hunting.

Aki/Nightshade smirked. Sounds fun.

Two tentacles shot out and attached themselves onto a nearby building, then instinctively retracted, catapulting Aki into the air. Aki cried out in happiness as the adrenaline kicked in. The symbiote guided Aki/Nightshade through sending out tentacles like a former symbiote host did with webbing, but she was catching on quickly. They were now swinging above the streets of Neo Domino, their black second skin camouflaging them in the darkness of the night.

Aki was enjoying every second of the pseudo-flight, which the symbiote was feeding off of. But the symbiote was still ravenously hungry, and wanted something a bit more than just an adrenaline rush.

"I've got something coming into this timeline."

"What now? Another Venom symbiote?"

"Negative. It's Trishder. Again."

"Ugh! Does that imbecile not understand that timelines are supposed to be preserved?"

"Apparently not. Should we deal with him?"

"…No."

"Why not? He's obviously a thre- Oh."

"Let's let our new friend deal with our old adversary."

Cireneg Trihsder stood in the cold, dark alley, waiting for the local thugs he had hired to get back. The plan was rather ingenious: Kidnap girls from very similar realities, then trade them in between realities. The alternate reality girls will be returned to their parents for a nominal stipend, but they wouldn't be the correct version of their daughter. Each reality would have to pay even more to get the real one back, and the cops would never find Trihsder, because he was so average, he could blend into any crowd!

The goons finally ran into the alley, but they didn't have anyone with them.

"Well?" Trihsder asked, impatiently.

"We tried to jump this chick, Aki Izayoi, but she summoned meteors, and-"

"Wait. Did you say 'Aki Izayoi'?"

"Yeah. What about her? She's just a Psychic freak! She's harmless!"

Trihsder rubbed the bridge of his nose at the idiocy of his colleagues.

"Look. I don't care if you go to the hospital for this, but I want that girl in front of me by midnight, or there will be consequences!"

"Yes, sir!" The lackey leader replied as he ran out.

Trihsder pulled out a cigarette and lit the smoke, taking his mind off of the pressures of personally running a criminal empire across universes.

Aki continued to swing through the city, but was turning back to the Daimon Area to her apartment. It was getting late, and she needed the rest.

No! We are still hungry!

But I'm tired!

Trust me, you will feel better once we-

The duo's trains of thought were derailed as Nightshade passed over the trio from earlier in the evening.

How about them? Would they satisfy your needs? Aki asked, the seeds of vengeance starting to take root.

Yes. They will satisfy our cravings. The symbiote coldly reasoned. Aki swiftly landed in a nearby alley, and wondered what she was going to do, until the symbiote suggested something. I can change out appearance to look human again.

Excellent idea. Aki replied.

The symbiote started to shift and regress as Aki emerged from the goo, changed. She now had black eyeliner and lipstick, along with black tips on her bangs. The symbiote's outfit changed into a black and pink tank top and shorts with a deck box strapped to a black leather belt and a black, organic-looking Duel Disk. Curiously, Aki was unaffected by the subzero temperatures.

One of the goons saw Aki, and grinned like the Cheshire Cat as the girl walked out of the alley and beckoned him in. He looked around for his friends, saw no one, and decided to have a little fun with the girl before all was said and done.

But as soon as they were both in the shadows, he screamed, and was quickly silenced.

Harvey was getting bored, cold, and tired, though not necessarily in that order. He, Mack, and Jesse, the boss, were looking for that dumb broad from earlier, but it was pretty late, and the snow was coming down harder now.

"B-Boss…" He stuttered in the freezing temperature. "C-C-Could we j-just give up on th-th-this stupid t-t-task? She's p-probably g-g-gone by n-now!"

"No!" Jesse barked. "I'm the goddamn cousin of Joey Wheeler, and I have a code of honor to uphold to!" The twenty-something high school dropout replied.

"But B-B-Boss, we're cr-criminals! We d-d-don't have h-honor!"

"Well I do! Say…where did Mack go?"

"I d-d-don't kn-know. Maybe he w-w-went h-h-home."

"Well, go find him, you idiot!" Jesse barked.

Harvey ran off into the snowy night, looking in alleys and trying to locate his comrade, when, out of the shadows, their prey emerged in a very sexy outfit.

"Hey, big guy. You look pretty cold. How about some nice warm hot coffee?"

"S-S-Sure, but I n-n-need t-to ask you s-something f-f-first." Harvey decided to play it cool and let the girl's guard go down until he took her out. Besides, he would get free coffee! It's a win-win situation!

"Sure. What's the matter? You look a bit worried."

"My fr-friend was ar-r-round here s-somew-w-where. D-Do you kn-know what h-h-happened t-to him?"

"Bald guy with a black sports jacket?"

"Y-Yeah! D-D-Did you s-see him?"

"He went off in search of you, but he might come back for some more coffee. Now, why don't you come with me?"

The two of them slinked off into the shadows, but they emerged in a small office with a coffee maker.

"Here you go! Some nice piping hot coffee!"

Aki poured Harvey a glass, and offered it to him.

"WHAT? I thought you were going to give me the other meaning of hot coffee!"

"What other meaning?" Aki replied innocently, really knowing what he meant.

"You know…something else that's hot…that a guy and a girl do together…"

Aki cocked her head in faux confusion.

"Ugh! When a man and a woman love each other very much-"

"Oh, that! Why would you want to do that to me? I'm only 16!"

Aki currently looked a few years older, but Harvey was too angry to correct that. Harvey unzipped his jeans, grabbed a startled Aki, and pinned the girl so she couldn't move. Aki meekly protested and struggled as he undid her clothes, and proceeded to force his now erect cock into her pussy, ready to do her doggy style so he wouldn't have to see the pain on her face. He enjoyed himself while Aki gave into the pleasure, but suddenly, some black stuff started to leak from her clit, and it coated his manhood and her vagina, making the friction inside of her walls go away, but trapping his penis inside of her. Furthermore, he felt his dick become stimulated by the gunk, and get even bigger. The gunk flowed over both of them, until it completely coated them, with the exception of Harvey's head. Aki's "clothes" had rejoined the mass, and she was now Nightshade again. Harvey, both freaked out by the current turn of events and very aroused by the current turn of events, couldn't hold it back, and finally orgasmed inside of Nightshade, making her purr in satisfaction. But, Harvey discovered that he couldn't move due to the black slime, and panicked. Nightshade easily disengaged herself from Harvey, got back up on both feet, and turned to face Harvey.

"So, you're a rapist?"

"Please don't kill me! I know I have a problem, but I've been working on it with my counselor! It's only when I get really upset that I snap!"

"You are very lucky I am somewhat of a sadomasochist, or I would be making sure you die slowly and painfully!"

"So you'll let me go?" Harvey asked meekly.

"I said I wouldn't kill you slowly and painfully. I never said you weren't going to die."

Nightshade approached the erect dick and simply let the tip circle her cunt, pleasuring both parties and especially torturing Harvey and his enlarged penis. After a few minutes of this, she slowly slid the cock inside of her, eliciting a gasp from Harvey. The symbiote sludge covering him would not only prevent him from cumming, but was stimulating his balls, ass, and dick, making sure he was very comfortable. Harvey hadn't had a desire to release this badly, and he could feel his cock becoming engorged with semen. Nightshade started to gradually build up the speed of the thrusts, but as she did so, she stepped forward, absorbing Harvey's legs into hers. They were now conjoined at the hip, but Harvey could still feel his manhood, although he no longer had any feeling from his pelvis area down. They continued to build up, and Harvey's mind continued to fog over in lust. His assailant was beautiful in a deadly way, like a Venus Flytrap. She had a grace to her, but she still had an aura of danger. Finally, after what seemed like forever, Harvey and Aki both came. More of Harvey was absorbed, until he was simply a head on a stalk attached to her upper torso. He was still feeling his cock pump Aki/Nightshade full of semen, but the rest of his body was gone. Just as the final waves of pleasure started to subside, Nightshade opened her gaping maw, and Harvey's head was thrown in.

He didn't feel a thing.

Aki gulped down Harvey as his memories were added to her own. He was a two-bit thief with no future that was passed from one gang to another, just like Mack, until Jesse recruited them as his personal assistants. They met a guy named "Trihsder" who paid them in gold instead of money, but instructed the trio on how to successfully pull off kidnappings. They had recently met Trihsder, who wanted Aki for some reason, and now their leader, Jesse, was waiting patiently a few blocks away.

Aki felt re-energized from all of that cum, which was being converted into symbiote mass for future use and hypercompressed into her tentacles for storage, just like the rest of Harvey and Mack. The duo had fed the symbiote well, and a happy symbiote meant a happy Aki, but Aki now wanted to finish off the trio by going after their leader, Jesse Wheeler.

She left the office and ran off to go challenge Jesse.

"Well, that was interesting."

"The symbiote must be fueling her appetite for sex."

"Well, let's keep an eye out for anything that might try to get in or out of this timeline. We don't want Trihsder getting past us this time."

"Also, Aki might like a villain to go up against."

"What? Are you suggesting she might become a vigilante?"

"Hopefully. That's a best-case scenario."

"And what's the worst-case?"

"Ever seen a movie called 'Cannibal Holocaust'?"

"No, but that raises several questions, like 'Why is it called that?', 'Why do you know about that movie?', and 'What does this movie have to do with the situation?'."

"Go look it up. That movie would be rated G compared to what Nightshade might be capable of doing."

Jesse finally gave up and started to head back to Trihsder when something descended from the black sky. It was female, but it had pink sections, including a pink head, and it was staring at him from a pair of white blotches where the eyes must be.

"What the f**k are you?" He cried out.

"We are Nightshade." Aki/Nightshade growled. "You have been harming innocent women. Now, you will pay."

"Well, if you want to turn me in, you'll have to get though my monsters first!" Jesse activated his Duel Disk.

"Sure. I'm going to enjoy this." Nightshade purred as she responded in kind, her Duel Disk changing into its fighting configuration.

"LET'S DUEL!" They both cried out.
