Chapter Text
The morning started out like any other. For Danny Fenton, that meant running late, scarfing down a toaster strudel while wrestling with his backpack, and dodging his dad’s newest invention that had decided to target him. He’d been a halfa for about two years, and his parents’ devices still couldn’t tell him apart from full ghosts.
By the time he’d made it to school, Tucker was already halfway through explaining why the newest PDA model was “life-changing,” while Sam was, predictably, unimpressed.
“Danny, please tell the nerd that this is just another overpriced toy,” she requested, flicking her dark hair out of her face as she leaned against her locker.
Danny adjusted his backpack, quirking an eyebrow at his friend. “Honestly, Tucker… last time you said that, the thing caught fire during lunch.”
“That was operator error,” Tucker said defensively, cradling the small device like it was sacred. “Besides, this one has a built-in ghost energy scanner. I could help you detect trouble before—”
RIIIING!
“...before the bell ruins everything,” Sam finished dryly.
They split up for class, and for a while, the day felt… normal. No alarms, no ghost sense, not even Dash trying to shove him into a locker. It should’ve been a relief, but Danny didn’t want to get his hopes up quite yet.
The final bell for the last class before lunch rang through the halls, and Danny swore it sounded smug about it.
He slumped over his desk as Mr. Lancer launched into a monologue about The Iliad. Sam seemed to be doodling in her notebook, though who could say for sure what she was actually doing. Tucker was stealthily swapping out his PDA battery, and Danny’s eyelids were fighting for their lives.
“Mr. Fenton,” Lancer said sharply, “if you’re planning to nap through the Trojan War, you might as well join them on the battlefield.”
Danny startled upright. “N-no, sir! I’m awake!”
“Good. Then perhaps you can tell us what Odysseus represents.”
Tucker whispered, “Sleep deprivation?”
Sam bit back a snicker. Ducking her head, noting only the briefest quiver of the shadows in the room.
Danny elbowed Tucker and fumbled for an answer. “Uh, trickery?”
Lancer blinked. “Correct, though I’m not sure how you managed that.” He sighed. “Try applying that cunning to your next exam, Mr. Fenton.”
As Lancer turned away, Tucker leaned over. “Nice save. You’re getting better at bluffing.”
“Years of ghost fighting,” Danny muttered. “You get good at improvising.”
Sam smirked, just knowing what her next words would cause “Speaking of, hasn’t your ghost sense been quiet today?”
He started to reply, and then the familiar wisp of cold air escaped his lips. “You had to say it.” Danny groaned. “Of course… Lunch break’s canceled.”
Outside, the air felt heavy, and thick with static. Danny ducked behind the gym and shifted into his ghost form.
The ghost wasn’t hard to find. It wasn’t even subtle. The thing was huge, taller than any ghost he’d fought in months. It appeared to be a new one. All teeth and scarred, translucent armor plating that shimmered faint iridescent colors, like some freaky modern art. The bestial ghost roared as it tore through a street corner, sending locals running and ducking for cover.
“Another feral one,” Danny muttered, making note to tell his friends that it's starting to happen more frequently. “Guess we’re doing this the hard way.” he grumbled, committing to dealing with the ghost before his parents could show up.
He shot forward, green energy crackling around his fists as the ghost lunged. The two collided midair, tumbling through a streetlight.
“Couldn’t you wait five minutes?” Danny grunted, firing a ghost ray that missed by inches, being testy that he was going to miss lunch.
The creature charged. Danny barely dodged, firing again, but his shots only deflected off the plates. The force of its swing sent him crashing into the pavement. He phased through instinctively, emerging behind it and launching another blast, yelping when the attack bounced back and slammed him in the shoulder.
This was new.
The creature shrieked, but before it could strike out again, a familiar looking portal tore open nearby, momentarily distracting both sides of the fight.
Danny blinked. “Wulf?”
The tall, lupine ghost stepped through, claws flexing and fangs bared. “Phantom fight bad spirit?” He asked, his hackles rising.
“Yeah, you could say that!” Danny yelled, dodging another clawed swipe as the feral ghost clearly had recovered first. At least the guy had been practicing his English, which made coordinating easier.
Wulf grinned, or something like it, and joined the fray. The two moved like a practiced team despite barely knowing each other, Danny phasing through blows while Wulf slammed into the ghost with brute force. Claws scraped metal and teeth snapped.
Danny darted in to help, striking at weak points in the armor. One of his blasts finally cracked a shoulder plate, but the creature backhanded him into a parked car, momentarily dazing him.
He powered up for a charged shot, but Wulf tackled the monster from behind at the same moment. They all rolled together, the other two ghosts snapping and biting. Danny couldn’t tell which was which and found himself trapped between the two goliaths.
The wolf ghost twisted suddenly, reacting on instinct. His jaws clamped down hard, but on Danny’s arm by accident.
The pain was white-hot and immediate.
“AH, Wulf! LET GO!”
Realization hit the ghost wolf instantly. Wulf released him, eyes wide and ears going flat in canine guilt.
He yanked back with a hiss, looking down. A faint crescent of teeth marks glimmered where Wulf’s jaws had briefly closed around his arm in the chaos, bright green ecto bleeding through. It didn’t look like much, but it burned.
Wulf drove his claws into the damaged armor on the front of the enemy, going right through like meat on a skewer. Danny put a swift end to the fight by collecting the enemy ghost into his thermos.
Wulf then whipped around, smelling the ecto-blood combo that he’d learned to associate with Danny. His ears flattened again, and he looked like a scolded overgrown puppy. Danny almost expected a whimper from him.
“Wulf, hey, it’s fine! I’m fine!” Danny said quickly, seeing how guilty his friend looked. “It was an accident. I know you didn’t mean it, and you still did great! I appreciate the help.”
Wulf looked unsure, but Danny’s words seemed to reassure him. “Good fight,” He said, giving Danny a heavy pat on the shoulder, looking down at the bite again. The bleeding was already slowing down.
“Y-yeah,” Danny replied, rubbing his arm. The pain was beginning to dull, more of a tingle now. “You, uh, really get into it.”
“Sorry,” Wulf said sheepishly, then rumbled a deep chuckle. “Phantom strong. You fine?”
“Yeah,” Danny agreed, forcing a grin. “I’m fine. I promise.”
But as Wulf disappeared back into his portal, Danny caught sight of the faint, silvery sheen lingering under his skin, right where the bite had been.
He frowned. Then shrugged.
“Probably nothing,” he muttered.
Later that night, Danny dropped face-first onto his bed with a groan. “Finally,” he mumbled into his pillow. “One normal –ow– day…?”
He lifted his arm and frowned. The faint crescent marks from earlier had already faded, leaving only a pale outline of a scar that caught the light when he moved. Weird. He normally didn’t scar. At least, not since becoming a halfa.
He poked it like a bruise, and it tingled weirdly.
“Eh, whatever,” he muttered. “I’ve had worse.”
From downstairs came the muffled sound of Maddie testing a new weapon.
THOOOOM!
Danny winced. “That sounded louder than the last test.” He mumbled, debating for a moment if he should be worried or not.
He rolled onto his back, staring at the ceiling and waiting for sleep to take him. It didn’t. His heart thudded a little too fast, and his skin itched like he’d had too much caffeine. By the time midnight rolled around, he was sitting on his windowsill, staring out at the moon, which just happened to be full.
It looked brighter than usual. Too bright. And for reasons he couldn’t explain… comforting.
The next morning, Danny woke up feeling like he hadn’t slept at all. His muscles ached, and not like the usual post-fight soreness, but deeper. He hoped he wasn’t coming down with something. It reminded him of how he always felt before getting sick with the flu.
Downstairs, the smell of bacon hit him before he even reached the kitchen. His stomach rumbled with hunger. Jazz sipped her coffee, giving Danny a sidelong look when he shuffled in, bleary-eyed.
“Late night?” she asked lightly.
“Yeah,” he muttered, trying to fake a smile. His voice sounded rougher than usual. He rubbed at his arm. The bite mark was completely gone now, but it tingled faintly under the skin. When Jazz’s hand brushed his sleeve as she passed him a plate, he flinched before he could stop himself. Everything felt off in a way he couldn’t put into words.
School wasn’t any better. The overhead lights buzzed loudly, and every locker slam echoed through his skull. Sam frowned at him between classes. “Are you getting sick? You’re pale even for you.”
Danny gave a weak laugh. “I really hope not.”
The worst part was his ghost sense. It kept going off even when no ghost was around. Every time it happened, his heart raced. His powers hadn’t misfired like that since Freshman year.
By the time he got home, he was exhausted but restless. He found that flying helped. His anxiety and restlessness appeared to ease while in his ghost form. Just as the sun went down, he landed on the roof of FentonWorks, looking out over Amity Park. The city lights flickered to life below.
He shook his head. “Must just be stress getting to me.” He stretched, and then allowed himself to drop all the way through to his bedroom.
That night he couldn’t sleep easily either. The moonlight spilled through his curtains, too bright to ignore. His heartbeat sounded loud in his ears. With a quiet groan, he dug through his nightstand until he found a pair of earplugs and the old sleep mask he almost never used. The world dimmed to silence and shadow, but his body still refused to settle. It took hours before his breathing finally slowed, and exhaustion pulled him under at last.
A few weeks later, the next full moon was beginning to peek at the horizon. Danny couldn’t explain why he felt so strange. Restless. By sunset, his nerves had begun crawling under his skin. Every sound seemed sharper. Even his parents’ chatter from downstairs grated against his ears and made him fidgety.
He tossed his homework aside and rubbed his temples. “What the heck is wrong with me?”
When the moon crested over the horizon, the pull in his chest deepened. Something instinctive, clawing just beneath the surface. Heat flushed through his chest, followed by a dull ache spreading down his spine. He doubled over with a sharp breath, teeth clenching against the strange pressure building inside him.
As a last resort to try escaping the building pain and discomfort inside his body, Danny went ghost.
The unpleasant sensations disappeared, completely and immediately.
Hovering in his bedroom, he blinked in confusion. “Okay, weird…” But the tension that had been twisting through his muscles melted away. The prior pounding in his chest came to a quiet stop. The restless energy didn’t vanish, exactly, but it turned instead into a hum of power beneath his skin, the kind that always came with flying.
So he did.
He slipped out his window into the cold night air, quietly soaring over Amity Park. The wind whipped through his hair, the cool air waking him up more. He flew faster, looping between rooftops, gazing up at the stars, and chasing away the unshakable agitation that had been building all day.
Hours passed. No ghosts appeared. Nothing to fight, and nothing to distract him. Only the steady rhythm of his flight and the distant glow of streetlights far below. The longer he flew, the lighter his thoughts became, like earth’s gravity couldn’t reach him.
By the time the first rays of dawn began to stretch across the horizon, the restless energy finally dulled. He sighed and drifted lower, phasing through his window as the sun broke the skyline.
He passed back into his human form. His skin still buzzed with leftover adrenaline, but his body ached with exhaustion.
“Guess that’s another night without sleep,” he muttered, rubbing at his eyes.
Still, at least the strange edge that had haunted him the night before was gone. He didn’t feel sick or sore anymore, just bone-deep tired. He would have taken a sick day if he’d thought he could get away with it.
Instead, Danny dragged himself through the school doors like the walking dead. His bag hung off one shoulder, his hair a half-brushed mess, and the dark circles under his eyes could have qualified as bruises.
“Dude,” Tucker said, sidestepping a group of freshmen as they made their way to first period. “You look like you got hit in the face with a frying pan.”
“Thanks,” Danny muttered, rubbing at his face. “Feel like it, too.”
Sam eyed him curiously. “Late night patrol?”
“Something like that.” He stifled a yawn and slumped into his seat as the bell rang. “Didn’t find any ghosts though.”
“Then why do you look like one?” Tucker asked, voice teasing but light.
Danny shot him a sharp look. “Maybe because I am one?”
That earned him a blink and a nervous chuckle from Tucker. “Uh, fair point.”
Sam frowned slightly. Danny wasn’t normally this grumpy. Even when tired, he’d usually manage a joke, or at least some sarcastic remark about the homework load. This morning, though, there was a tension in him that hadn’t been there before. It was like every little thing grated on his nerves, and he didn’t care about how snappy he got.
When class started, it didn’t help that Lancer was in one of his “educational monologue” moods again. Every scrape of a pencil sounded like nails on a chalkboard to Danny, and when someone behind him started tapping their foot, his hand twitched like he might phase through the desk and throttle them.
“Dude, chill,” Tucker whispered when Danny’s pencil snapped clean in half between his fingers.
“I am chill,” Danny hissed back.
Sam exchanged a look with Tucker. Chill? Yeah, sure.
By lunchtime, Tucker tried to lighten the mood with a joke about the cafeteria “mystery meat.”
Danny just glared at his tray like it had personally insulted him.
“Man, you’re seriously in a mood today,” Tucker said, eyebrows raised.
“Maybe I’m just tired of smelling whatever that is,” Danny muttered, shoving the food tray away. “Smells like… I don’t know, garbage and bleach had a baby.”
“Okay, ew,” Sam said, wrinkling her nose. “Your ghost senses acting up or something?”
He shrugged, running a hand through his hair. “Maybe. Or maybe the school just sucks. Take your pick.”
Sam opened her mouth to argue, but then stopped. He looked… miserable. Irritable, pale, and clearly not himself.
Tucker leaned back in his chair. “Alright, man, you need, like… twelve hours of sleep and maybe a vacation.”
Danny gave a humorless snort. “Yeah, let me just pencil that in between saving the town and failing math.”
Tucker grimaced and fell silent.
Sam frowned again. She couldn’t shake the sense that something more was going on.
By the time the last bell rang, Danny had managed to survive the rest of the day without blowing up at anyone else. Mostly. He slumped in his seat during the final class, staring at the clock as the minutes crawled by.
Sam and Tucker exchanged glances across the room, each silently acknowledging that something was off. Neither said a word. They didn’t want to push him any further.
When the day finally ended, Danny grabbed his backpack with a quiet groan and trudged toward the door. He felt relief at the school day being over, but couldn’t shake the uneasy itch nagging in the back of his brain.
“I’m going straight home,” he muttered, keeping his voice low. “No detours.”
Sam nodded. “Early dinner, early bed,” she said gently. “Seriously. Even ghosts need rest.”
Danny didn’t argue. He just let the words hang in the air as he walked. The sky outside was still a warm gold from late afternoon. His feet shuffled along the cracked sidewalk, the day’s stress weighing on him more than he realized. “Food, and then bed.” He repeated Sam’s words like a mantra.
Wulf crouched on a nearby rooftop, a silent sentinel. His head tilted slightly as he watched Danny make his way home. Protective vigilance gleamed in his canine eyes. The boy didn’t notice him, but Wulf had silently vowed to keep watch. He’d been observing him from the shadows, catching nothing alarming, but he intended to be certain.
