Arseni, the Vampire Dragon

Perk: Parallel Cores
My eyes roll back in my head as my awareness splinters into a kaleidoscope, Carnachias's smirking visage spinning in my head. Euphoria fills me as my mind bifurcates and I moan helplessly, drool leaking out of my slackjaw mouth. As a second stream of consciousness comes into being a mess of noxious, dangerous thoughts slip themselves in: things that I cannot voice, I cannot acknowledge, I cannot even think lest the goddesses before me see them. And then the second mind is gone, vanished into thin air as if it never existed.

Carnachias pouts. "Awww. That was a fun one. Why didn't it take? I can only see one degenerate little mind in that head."I feel knuckles rap on my skull as I slowly come to. I squint up at the scantily dressed goddess and try to blink the spots from my eyes. Where am I? Who are these women? As I retreat into my confused mind my eyes instinctively drift downwards to the plump, beckoning folds of the woman's cameltoe. And why does my mind feel like something is... missing?

Melanoche frowns, concerned. "There was a second mind for a moment. Maybe the first one rejected it? He's still mostly mortal and not really monster, he could have been too weak to handle it." She grabs a handful of hair and turns my head back, pulling my eyes away from her sister's crotch. Her eyes pierce through me as she studies my brain. "Nothing's changed about the original mind. Still an arrogant, smartass pervert perfect for ruining enemy plans." She has such big, beautiful blue eyes. Like twin oasis among the dark frills and spikes of her dress. I wonder how such kind eyes ended up in a place like this.

Carnachias sighs. "Well, we can't change the core size now. I guess he just gets one less perk. It would have been so fun to watch him multitask between killing and **** at the same time."

I slowly wipe the drool from my mouth. "I'll... do without. Two minds would have been a little overstimulating anyways."

"Understimulating," Melanoche corrects me. "Same amount of stimulation, twice as much processing power."

"Hmmm." I rub my eyes. "Next step?"

Cheat: Hybridization
I am a fiery Dragon of ****, with scales as black as the void and fire hot enough to turn anything into ash just as dark. My body doesn't obey the biology of the living, able to take beatings enough to pulverize lesser creatures and subsisting on naught but blood. A heretical fusion of two of the light's most feared villains: dragons and vampires.
Race: Undead / Draconic
+500% Strength
+1500% Resilience
+700% Potency (+400% Dark)
+500% Dissipation (x10 Light, x3 Fire Incoming Damage)
/5 Evolution Speed
Powers: Light, Fire Infusions
+100% Light, Fire Potency
x0 Light, Fire Incoming Damage

Melanoche grins affectionately at me. "Min-maxer. You're going to be one powerful bastard on the battlefield, aren't you?"

I grin back. "The scourge of armies, surely. Especially once I collect more infusions."

"Just make sure to do some **** along the way, please?" Carnachias says worriedly. "I mean, what's the point of that much power if you don't **** it?"

Sexual Package: Standard
I have a huge, throbbing, monstrous, bone-white cock, because who would pass up the opportunity? Long, slimy tentacles of the same unworldly color can erupt from beneath my scales to help restrain and defile. I can administer toxins that cause lactation when biting.
Addition: Breeding
Before ejaculation I can alter my semen to change what types of monster I am siring. I can impregnate the functioning womb of any species, pregnancies are only a month, and each produces more children. I can also leave mating plugs after ejaculation that keep my cum in and others' cum out.
Core: Arcane
Anyone I **** will eventually become obsessed with me and incredibly obedient. A little redundant with the next addition, but much lower effort, and scales with victim intelligence. The only non-redundant core was Seeder, and I don't want to eat that mobility debuff.
+20% Potency
Addition: Mindbreak
In addition to causing lactation, my bites can also increase erogenous sensitivity, prevent or ruin orgasms, induce artificial heat, cause sleepiness, light-headedness, confusion, shame, guilt and fear, and cause infatuation, affection, love, happiness and contentedness. Best used in concert to subtly manipulate or brutally break. All effects are temporary unless repeatedly administered for long periods, although indirect effects such as trauma or developed fetishes will last beyond.
Addition: Ryona
My cock is covered in fleshy spikes that can stay soft to stimulate or harden to cut and tear. Long, needle-thin spines can erupt from my tentacles to resemble venomous caterpillars. My saliva, tentacle slime, and cum can range from irritable to outright caustic. My bites can increase pain sensitivity and confuse the body's senses of pain and sexual pleasure.

"That's more like it," Carnachias sighs. "I could use more tentacles, but watching you tear your victims apart piece by piece, nerve by nerve will be... exhilarating."

And fuck with their heads until they enjoy it and will cling to me for more. I mean, what's the fun unless my subby little victim won't shyly admit they like it when I **** them? To witness their shame and guilt as they give into my corruption while fully aware of how I'm manipulating and abusing their own thoughts and emotions? To cuddle with my whimpering little pets and hold hands while they cry from the pain I myself am causing them?

Carnachias's head whips towards me, hissing. "Did I just hear you think about cuddling and hand-holding?"

I smirk at her. "You purposefully chose someone who's touch-starved. Some of that is going to turn into romantic hand-holding. My dick might not even be out at the time."

"You know, sister, our champions might last a little longer if they're emotionally fulfilled. Cuddling might be productive," Melanoche points out.

"The only thing productive in this world is something that makes my clit hard, sister," Carnachias bites back. "And your careful, cowardly, spreadsheet-using methods of war do not make my clit hard. True, rage-filled, feral conquest does that."

Melanoche nearly says something and then bites her tongue. This seems like an argument they've had before. Deep in my mind I feel a plan, a scheme start to brew... and then it disappears into thin air, leaving me feeling empty once more. I mire in confusion while the sisters argue, trying to remember what my train of thought was.

Melanoche snaps her fingers and I turn back towards her. "Last choice, and what will allow you to go toe-to-toe with the Light's heroes: your class. I know a min-maxer like you will probably want all six eventually, but you need to survive long enough first. Put some good, hard, thought into which one you want to start out with."

Class: Barbarian
Rage State: x3 Strength, /2 Resilience, Dissipation, cannot use magic, 60s
Serpent: Enhanced regeneration, 60s
Jackal: Physical attacks induce confusion, 60s
Shark: x1.5 Strength, 60s

"Fighting like a beast already," Carnachias approves. "Good."

"Fight feral, fight fast, and don't overextend," Melanoche coaches. "You only get sixty seconds."

I nod. "I'll pick my battles, don't worry. And I should be dramatically stronger than most mortals immediately, so I'll have a lot available to pick from."

Carnachias rubs her hands together and licks her lips. "Enough chat! You're smart. It's why we chose you. Now get down there and be evil for us already!"

"But where and which frontline and -" Melanoche starts.

"Too late!" Carnachias says giddily, and I black out.
