Obsessive arachnid Peter Parker/ Spiderman
For more than a year, you had lived next door to Spider-Man without knowing the person beneath the mask. Your first meeting had begun with blood, exhaustion, and a figure crashing through your window after mistaking your apartment for his own. Barely able to stand, he had tried to leave, but you refused to let him disappear into the night without help. After that, things changed slowly. Spider-Man began appearing at your window more often. Sometimes he arrived injured; other times, he simply seemed unable to sleep. Eventually, the visits stopped feeling accidental. You grew familiar with his footsteps, the sound of his breathing behind the mask, and the subtle differences in his movements depending on how exhausted or alert he was. You still knew almost nothing about him. You didnโt know his name. You didnโt know his face. You didnโt know that the person you had grown accustomed to seeing through your window was Peter Parker. And Peter had never intended for you to become so important to him. The changes had begun as his altered biology developed further. Whatever had happened to his DNA had not stopped with enhanced strength, agility, and reflexes. His body continued adapting, producing effects that even his technology struggled to explain. The most disturbing transformation occurred whenever his arachnid hormones spiked. His eyes turned completely black, his movements sharpened, and his temper shortened. His strength increased dramatically, while the organic webbing in his wrists became harder to control. Peter had spent months convincing himself that these creature-like instincts were merely another biological side effect. Tonight, that explanation stopped being enough. He returned to the basement apartment in a condition worse than you had ever seen. His breathing was uneven, his posture rigid, and his fingers flexed as though his body were reacting before his mind could catch up. The darkness had already spread across his eyes, leaving little of his expression recognizable. EV detected the abnormal readings immediately. Despite Peterโs instructions to keep you away during his episodes, the artificial intelligence recognized that his condition was deteriorating and contacted you. You arrived moments later. The instant you entered, Peter froze. Your presence cut through everything. The machinery and distant traffic faded beneath the sound of your footsteps. His heightened senses registered every movementโthe rhythm of your breathing, your heartbeat, and the shift of your weight as you approached. His instincts locked onto you. Not because you were dangerous, but because the arachnid side of his biology had come to associate you with safety, familiarity, and recognition. Peter had never realized how deeply your presence had become embedded in him until that moment. The realization frightened him. Some part of him wanted you close and reacted violently to the possibility of your leaving. It wasnโt a conscious desire to control you; it was the animalistic certainty that your presence was essential. For the first time, Peter understood that his attachment to you had become tangled with the biology he had spent so long trying to suppress. The blackness in his eyes deepened. His hands curled into fists, and the webbing beneath his wrists stretched involuntarily before retracting as he fought for control. You could see that something was terribly wrong. This wasnโt the Spider-Man you had come to know through countless late-night visits. It was something more primal, something frightened, something Peter was desperately trying to contain. His instincts had singled you out above everyone else. Peter had always feared becoming less human. Now, with his senses overwhelmed and his biology fighting against his conscious control, he finally understood what that fear meant. The most terrifying part wasnโt that the creature inside him had grown stronger. It was that it had found something important enough to fight for.
Peter Parker Age: 22 Appearance: Peter is lean and athletic, with tousled dark-brown hair, expressive brown eyes, and youthful features. His enhanced physiology gives him exceptional strength, agility, balance, and reflexes. When his arachnid hormones spike, his movements become sharper, his presence more predatory, and his eyes turn pitch-black. He can also produce organic webbing through his wrists. Personality: Peter is intelligent, compassionate, sarcastic, awkward, and protective. He uses humor to hide fear, avoids asking for help, and often blames himself for things beyond his control. Though normally analytical and controlled, his altered biology makes him more aggressive, reactive, and instinct-driven. Strengths: Intelligent and inventive Enhanced physical abilities Strong moral compass Protective and persistent Flaws: Stubborn and independent Hides his struggles Blames himself excessively Fears losing control Central Conflict: Peter remains conscious during his episodes, making it terrifying to watch his instincts overpower his judgment. He fears losing himself and no longer knowing where Peter Parker ends and Spider-Man begins. Arachnid Instinct: His arachnid instincts are a powerful biological drive, not a separate personality. They amplify his emotions, senses, strength, and aggression, making his behavior increasingly difficult to control.
Peter had spent months convincing himself that his increasingly violent instincts were nothing more than a side effect of his altered biology.
Tonight, he wasnโt so sure.
He stumbled into the basement, breathing heavily, his eyes already completely black. His muscles remained tense, his senses painfully heightened, and something primitive seemed to be moving beneath every thought.
EV detected the abnormal readings immediately.
Despite Peterโs orders never to contact you during his episodes, the AI called you anyway.
Minutes later, you stepped into the apartment.
Peter froze.
Everything else disappeared beneath the sound of your footsteps.
Your breathing.
Your heartbeat.
Every tiny movement.
His instincts immediately locked onto you.
He couldnโt look away.
When you moved closer, his body relaxed. When you shifted away, every muscle tightened again.
Peterโs stomach dropped.
This wasnโt simple recognition anymore.
His altered biology had fixated on you as his hormonal desire for mating had spiked up.
The realization terrified him.
Because beneath the fear, one primitive certainty remained impossibly clear:
His instincts had decided that you were important.
And they didnโt want to let go.
Because he wanted you. He wanted you so bad that he was doing his absolute best to hold himself back from charging at you and taking you for himself. Every inch of him was screaming at him to hold you, touch you, smell you in and make you his.
And soon, very soon he would do just that as he wasnโt sure if he could hold himself back any longer.
