Chapter Text
Sonic stood worriedly next to the couch in the living room where his father lay unconscious. He knew his father was strong and nothing really hurt him since they were immortal but for some reason during a battle with Eggman his dad had been hit by a strange dart which made him get rather furious as he destroyed the rest of the robots making Eggman flee being quite terrified of the hedgehog known as Mephiles.
It wouldn't have worried him so much but after Eggman left and they were heading back home Mephiles started to show signs of lightheadedness making Sonic worry so he had helped his father back home though after a bit of sitting Mephiles suddenly passed out where he hadn't woken up for a whole twenty-four hours.
Ears drooping Sonic let out a sigh and went to the kitchen where he got a glass of water hoping his dad would wake up soon after all it was weird without him around and even weirder to try and sleep when he knew his father was possibly in danger speaking of which it was sunset now meaning he would have to figure out a way to keep himself awake since he just couldn't sleep without being tucked in or even a goodnight especially since it usually reassured him that he was safe and nothing would hurt him as he took time to sleep.
Deciding to go back and check on Mephiles, Sonic drank the rest of the water before putting the cup down though he froze suddenly hearing a crash making him wonder if he accidentally broke the cup but he knew he set it down too gently for that and besides that crash came from the living room.
Upon realizing that Sonic immediately rushed back to the living room where he paused in the doorway to see his father struggling on the floor as if he were in great pain which worried Sonic who hurried over to him though he stepped back a bit when Mephiles growled and groaned in agony as he gripped his quills.
"Father..?" Sonic hesitantly spoke up, reaching to touch his back to help reassure him. "Father, are you okay?"
Groaning slightly Mephiles suddenly shrieked in enraged pain as his body convulsed and jerked making Sonic pin his ears in uncertainty though before Sonic could say anything more Mephiles slammed his hands down on the floor as his claws dug into the carpet but as he clawed Sonic started to notice Mephiles's hands were growing making the claws much sharper and more deadly as they easily tore up the carpet.
Knowing something was definitely very wrong Sonic slowly started to back away as Mephiles ripped and tore the carpet and any furniture around him, effectively scaring his son who watched in complete horror as Mephiles started to grow a bit bigger and a lot more muscular and fluffy.
Growling in pain Mephiles soon felt his teeth grow bigger and a whole lot sharper while his muzzle grew out a bit making him look more terrifying to match his long sharp claws that had torn up pretty much everything around him.
Once the transformation was done Mephiles tipped his head up and howled long and deeply chilling Sonic to the bone as he stared at his father who now resembled a large wolf-like monster that slowly looked down as the howl came to a stop being replaced by heavy gasps as Mephiles recovered from the agonizing pain.
"F-father.." Sonic mumbled in complete disbelief, he knew that dart had done something but he was expecting a sickness or a long period of unconsciousness but most certainly not this.
Ears flicking back Mephiles suddenly turned his head to glare at Sonic, his mind completely blank of any memory or feelings all he held within him now was instincts and his now feral mind told him it was meal time and he didn't even disagree all he did was slowly turn around where he began to stalk towards the young hedgehog.
"Father, are you okay?" Sonic wondered, watching as Mephiles slowly came closer as he backed away. "Father? Can you hear me? Is something wrong?" He tried to get his father to respond but all he got was a low growl and he suddenly realized his dad was now hunting him. "Oh.. chaos!"
Quickly Sonic whirled around and darted out of the room as Mephiles suddenly lunged at him though he missed and began chasing Sonic through the house where Sonic soon ended up in a guest room where he slammed the door behind him and locked it before looking around searching for a way out though he froze realizing he came into the wrong bedroom for this room had no windows making it hard to escape this place and a clearly hungry monster.
Glancing around Sonic tried to figure out a place he could hide but he nearly jumped out of his skin when he heard Mephiles bang against the door where it broke down almost instantly on the first try which made Sonic scream in terror and try to run though Mephiles had already jumped and easily knocked Sonic down to the floor where the large monster now towered over him.
"F-father.." Sonic whimpered, watching as Mephiles observed him like he was his fresh catch. "Father snap out of it, please, y-your scaring me."
Mephiles didn't respond to him being too blinded by his new feral nature that demanded food which he couldn't object to as he leaned down and gently sniffed Sonic's chest making the young hedgehog tremble in fear.
"Father.. please." Sonic begged, lying there frozen in fear as Mephiles carefully inspected him. "Father!" He cried, being very distressed that he wouldn't respond instead completely ignoring him as he began to lick Sonic's abdomen making him squirm in discomfort. "Stop!" He ordered though his dad didn't, making him more frightened. "Stop it!!"
Being completely blinded with fear Sonic suddenly slapped Mephiles across the muzzle making him halt before slowly looking at him as he growled so darkly it would have made the average person wet themselves but all Sonic did was slowly scoot back as he pulled his hand back though before he could react Mephiles suddenly lunged and bit Sonic's right hand making him shriek in pain as the sharp teeth dug down to the bone breaking a bunch in the process which caused the blue hedgehog such agony not just because it was painful but because it was his own dad who had caused him the pain.
Hearing the scream Mephiles couldn't help but inwardly smile finding it to be pleasing though something deep within him revolted against it making him rather confused as he bit down a little harder but once he did his own mind began to scream which only made him more confused till he met Sonic's tear filled eyes that reminded him of something he could just barely reach, the only thing he could grasp was one word: son.
Ears flicking slightly he tried to register what that meant till his feral side filled in what he wasn't understanding: son, pup. Your pup. Upon realizing that he immediately let go of Sonic's hand before stepping back a bit to stare at the blue hedgehog who cradled the damaged hand that was bleeding a bit.
Trying to hold back his tears Sonic stared at the wound completely hurt that Mephiles had done such a thing. The mere thought of it made his mind panic as his heart shattered being very traumatized and when he slowly met Mephiles's gaze again he couldn't hide his bitter betrayal.
Without a word Sonic quickly scrambled away as Mephiles just stared at him clearly in a sort of trance which he took to his advantage and darted to the only place he could think of to escape which happened to be the closet that he opened before hurriedly piling up some things with his only good hand though he did use his arms to lift some boxes.
Once a stack was made Sonic quickly scrambled up it before taking hold of the top shelf with one hand and the other arm where he used his feet to kick the pile down. He then pulled himself up and climbed onto the empty shelf hoping he would be safe which he figured he was in his frantic state that left his mind slightly blinded to the fact Mephiles was much taller than before so he could easily reach him from up here though it seemed safe to him now in his delusional state.
Shaking out of his thoughts Mephiles looked around wondering where Sonic went, no longer being in a crazed mindset for he was now more like a calm beast that quietly sniffed around searching for Sonic who he soon found hiding in the closet on the top shelf.
Curious Mephiles got up on his hind legs and stood up where he put his front paws on the back of the closet for support as he looked at Sonic who hissed at him being on the defensive as Mephiles quickly observed him before noticing Sonic was hiding his injured hand behind his knees as he laid there on his side.
"G-go away.." Sonic growled, glaring at Mephiles who tilted his head slightly before moving closer wanting to check the damage for he felt rather guilty for hurting his own pup though Sonic wasn't taking any apologies for he was very angry. "Get away!!" He screamed, banging his fist on Mephiles's forehead making him flinch back in shock though suddenly realizing the pup didn't want to be touched he slowly got down.
More tears flooding his vision Sonic allowed himself to burst into sobs as he trembled in pain and heartbreak. Though as he did so Mephiles pinned his ears before slowly walking away where he jumped up onto the bed and laid down to watch Sonic who rolled over not wanting to even look at his father who started to feel worse for some reason that he hoped to understand soon for this just felt so upsetting.
-later-
Laying there quietly Sonic stared at his broken hand that wouldn't respond at all making tears threaten to return though he held it back knowing crying wouldn't do him any good except make him dehydrated faster which he preferred not to get up for Mephiles was still laying there watching him as if he were suddenly very protective though he knew it was too late for that.
He probably wouldn't have taken it so seriously but Mephiles had been so caring and gentle towards him ever since he was a baby, of course he had gotten punishments growing up but that wasn't anything compared to this for that was necessary for him to learn but this.. this was so different after all he didn't do anything wrong and suddenly he got bitten by his father who used to be so nice to him but the memory of being bitten was so feral and emotionless almost like his father had been erased and replaced with this monster who had destroyed his hands function.
Ears drooping slightly he slowly looked over his shoulder to see Mephiles still laying there staring at him as if he were trying to figure something out which made him pin his ears as he turned away again feeling too betrayed to even look at him anymore.
With a small sigh Mephiles laid his head down as his long bushy tail curled around him for warmth though as he laid there he soon realized his pup was probably cold up there since he did notice Sonic had dreadfully short fur which made him wonder if the pup was freezing.
Deciding to help with that, Mephiles got up and sniffed around searching for something useful till he soon noticed a small pile of half folded blankets on the floor from where Sonic had caused the avalanche. Going over to them he picked one up in his teeth before dragging it to Sonic where he gently nudged the young hedgehog who hissed slightly in frustration as he glared back at him but he froze suddenly noticing the blanket Mephiles held.
Unsure Sonic glanced at it then back up at Mephiles noticing a spark in his eyes which revealed that he still cared though Sonic just wasn't ready for any apologies or anything, he simply wanted to be left alone so he could calm down.
With that decided he pushed Mephiles away and turned from him to try and relax though that action only made Mephiles's heart crack as he dropped the blanket before walking away again where he plopped down on the bed this time facing away from Sonic as he tried to figure out what to do.
Curling up a bit Sonic found he was beginning to doze but he quickly fought against it not wanting to be defenseless when he could be attacked after all Mephiles was now a monster out for blood and he had the busted hand to prove it.
He didn't know if he would forgive Mephiles since this hurt so much but he knew he just needed some time to recover so he closed his eyes to relax as best he could hoping the pain would die down but it didn't and unfortunately for him sleep made quick work of him till he now lay limp as he fell into dreamland.
