Darker side of the moon.

"Hmmm...veeeeery interesting,"

The 19-year-old twin tailed fox examined the little werehog in his presence with great fascination.

Tails, otherwise known as Miles Prower, had been aroused from his sweet slumber by a sharp knocking on the door of his workshop and he had been greeted by his best friend Sonic and his wife Amy. The foxy tailed mechanic was both intrigued and stunned when he noticed that the little hedgie which was his nephew had been transformed into a Werehog and was now taking the time to examine him.

Quite honestly, this whole situation had mystified Tails and also -quite rightly- terrified his parents. He set Boost down on the cold metal table and studied him as the little werehog pup just lay on the surface of the sterile piece of furniture and studied his surroundings with massive yet inquisitive eyes that clearly wanted to explore everything and anything within his view.

His namesakes swished in the air while he carefully looked over the little indigo and pink werehog that was in his presence.

The twin-tailed fox teen opened Boost's mouth and stared at the rough pink gums inside, even examining the tiny fangs that were starting to come through. All the while Sonic explained what had happened for things to lead up to this.

The cobalt speedster finished his story with a worried shrug.

"...And that's why we came to you."

Tails nodded in acknowledgement and then turned around to stare both Sonic and Amy whom both looked right back at him worriedly. He noted that Amy had been still been wearing her pyjamas and was wearing a long pale pink gown, she even threw on a cardigan on top, and a pair of bright red slippers.

The pink hedgie clasped her hands together. Her brows knitted together and a massive frown had been sculpted on to her pale peach muzzle, her tired eyes were large and glossy with fear and she looked to have been the absolute epitome of nervousness; but she had every right to be so, as her baby's future hung in the balance. She anxiously stepped forwards and spoke up in a surprisingly timid voice that was so out of character for her.

"How is he, Tails?"

Tails looked at Amy as a grin had graced his muzzle and he said "Welp. It seems that Boost is pretty healthy for the most part,"

Both Sonic and Amy simultaneously heaved a deep sigh of relief.

It was good to know that their little one was doing fine and that lifted a large weight from their shoulders when they heard this. Yet they kept looking at the fox since a "but" was probably about to come regarding this and was practically inevitable. Sonic was hardly even aware of when he wrapped a supportive arm around his wife subconsciously whilst he stared at his best friend.

Tails' smile evaporated a bit "But...it seems that I can only come up with one diagnosis: Lycanthropy."

That one last word had left a sinister atmosphere in its wake.

Amy broke down into tears when he legs gave up on her and she collapsed to the ground. Her hands trembled and her jade eyes gushed tears that flowed in endless streams down her face while her body convulsed and wracked with sobs, her throat closed and made her unable to even howl from pure grief. Her spine arched painfully when she clawed the ground beneath her.

Sonic's mouth fell open and his heart shook like an earthquake. He couldn't have heard that correctly, he just couldn't have heard that! He had to have misheard it...! But he knew deep down that he had, indeed, heard that word correctly and he could swear that he heard his mind drop from midair due to the fact that he just couldn't believe this; he had battled genies, he defeated a water monster, he fought with crazed gods, and he foiled the plans of a power-hungry doctor Eggman more times then he could have counted.

And this was something that came close to breaking him.

Unlike his wife, however, he couldn't produce any tears. He bit his lower lip to prevent himself from becoming a complete wreck and he considered that diagnosis: Lycanthropy...the term used for those who turn into absolute beasts at night, especially during the full moon.

Sonic silently stared up at his best friend.

Tails seemed reluctant to continue yet it seemed that there was more he had to say. He looked to his big brother anxiously and looked at him with a questioning gaze, obviously seeking Sonic's permission to continue.

He got it when the blue blur silently nodded at him.

The twin-tailed fox fiddled with one of his namesakes while he explained "It seems to me that the Dark Gaia energy that flowed through your body when you were a Werehog hadn't been fully drained from your body,"

Sonic listened silently, he knew which event his little brother was referring to.

Tails continued. His ears lowered and his expression grew a slight bit serious when he stiffly turned back to look down at the innocent baby werehog sat in front of him, his shoulders and two tails stiff and raised with tension.

"When I examined your X-Rays from a few years back, Sonic, I noticed that there was something unusual in your lungs. Some sort of foreign material or something..."

His tone grew low yet soft.

He started to slide his hands beneath the tiny pup in an effort to scoop him up into his embrace. Boost wriggled and squirmed in the teen's embrace as he was lifted off the cold metal surface and laid in the fox's palms in a rather snug fit, his small fluffy body gave a slight shiver while he started to make unusual noises. After picking up the small pup, he went over towards a big high-tech television screen that hung up on his wall.

The television screen projected an X-Ray image.

There was a rib cage on each side of the image (an indication that the screening was taken from the chest region) and there were also the slightly foggy depictions of the stomach and intestines and the liver and the heart...but to the right and underneath the heart was a strange collection of something that seemed to circulate and centre itself right in the middle of the chest.

Tails pointed to that mass with a gesture of the head and Sonic and Amy peered in closer.

That was the strange stuff that the fox teen had mentioned.

Amy cocked a brow and frowned with ignorant confusion, her bright jade pools solely focused on the image of her husband's anatomy. "What is it?"

Tails adjusted Boost in his hands to position him better and replied knowingly with his ears perked up and his eyes now sparkling with fascination. "I had a sample of Sonic's blood taken and I looked it ove-"

"YOU DID WHAT?" Sonic cut Tails off and interrupted in shock "WHEN!?"

Tails glared at the Blue blur. He disliked it when he was interrupted and even more so by the adult blue hedgehog who he considered his big brother, since his intellect was fairly large compared to most others it really annoyed him how his scientific rambles were rudely cut off by those who simply didn't understand all the words he used or if he was speaking too fast for their brains to absorb his words properly.

He blew out a steamy breath and responded with a cool glare "Not too long ago; please let me finish,"

Sonic said nothing and the adolescent fox took this as his cue to continue.

"Anyway...I looked over Sonic's blood sample and found a trace of Dark Gaia energy,"

Sonic's eyes instantly widened with shock and he interjected a second time "B-But that can't be right! Dark Gaia cured me of bein' a Werehog when he sucked out all that glowy purple stuff years back!"

The foxy-tailed mechanic shook his head and closed his eyes somewhat sadly. It would seem that Sonic had no clue about what had truly happened the time where he had been cursed to turn into a Werehog, he had been oblivious to it for so long and now it had come back to haunt him...it would be especially devastating when he finds out how bad of an impact it would have.

"It appears that Dark Gaia left a small amount of that energy inside and it became part of your anatomy," He explained "and because of this the remnants of the energy inside you must have passed on to little Boost and caused him to have the same transformations you used to."

Sonic and Amy both glanced at each other worriedly.

Their little Boost now had been cursed to transform into a Werehog, all because of what had happened to Sonic when Eggman had awoken Dark Gaia and broken the planet several years prior.

Tails rolled his eyes and muttered beneath his breath. "And having Sonic as the dad kinda doesn't help..."

Sonic scowled darkly at his adopted little brother. "Hey!"

Tails returned to his somber mood. "Anyways, I'm so sorry but can't help ya..."

Hearing that was like a brutal roundhouse kick to the stomach and it instantly created a reaction to the new parents, especially sparking a newfound rage inside Amy -the pink hedgehog's eyes sparked with rage and she clenched her teeth and clenched her hands into aggressive fists. Her whole form burned with fury and she stomped her foot so hard on the ground that it created a big dent in the metal-coated flooring of the foxy teen's workshop.

Sonic instantly saw the signs of his wife's anger and he swallowed a big fat marble.

"Ames...? S-Sweetheart-?" The blue hedgie called out to Amy in a cautious tone while he held a pair of hands out towards her to try and avoid any massive temper tantrums that would possibly end up in a massive murder spree caused by the pink hedgehog.

It didn't work.

Amy basically exploded as she reached behind her back and pulled her Piko Piko hammer out of nowhere "I AM GOING TO SLAUGHTER EGGMAN FOR DOING THAT TO MY BABY!"

The whole atmosphere turned from somber to very intense within instants after the pink female's outburst. The gloomy gravity of the whole workshop plummeted and was replaced with fear and discomfort for the state of the mother hedgie wielding the massive hammer. She didn't even seem to care that she was mad over something Dr. Eggman had done a long time ago and wanted to smash his head off for it.

Tails and Sonic were desperately thinking of how to prevent a likely potential case of manslaughter when suddenly a squeaky whimpering sound was heard and they both looked into the former's hands to discover that the origin of the noise was baby Boost, himself.

The dark indigo blue pup with pink patches whined and whimpered as he lain in Tails' hands and waved his tiny claws in the direction of Amy. He was constantly yipping and squirming and even gnawing his gums on the gloved fingers that furled around his tiny form to be let go; the baby werehog-transformed-hedgehog wasn't able to make it any clearer that he wanted to see his mother.

The foxy teen mechanic and the cobalt speedster looked at each other with uncertain frowns etched on their muzzles. Should they seriously hand the baby over to Amy? Tails didn't even take too long to dwell on it since Sonic was restraining his enraged wife and the female hedgie wasn't making it easy for her husband, so he reluctantly stepped forwards and quickly placed the whining pup in his mother's arms.

Amy seemed to instantly relax when Boost was back in her embrace.

Boost, content to be held by his mother again, let his tail waggle and he cooed and gurgle happily in his high-pitched husky tone. His tiny paws aimlessly waved around in the air yet he seemed to reach for Amy's muzzle; he yipped and squealed happily when Amy held her little one to her muzzle and her eyes lit up with happiness when the baby merely licked her nose with his teeny tongue. Amy's eyes filled with tears but she couldn't help but smile while she hugged her newborn and nuzzled him affectionately, her heart glowing with warmth.

Sonic had let go of his wife and was stupefied at what he was seeing.

As impossible as it seemed, it looked like Boost recognised that his mother was feeling upset and wanted to pacify her. It was far more miraculous that it actually worked! Perhaps Boost's dog-like instincts kicked in, despite him being so young, and he was a sweet little guy.

It made Sonic feel better about his son being a Werehog and he knew that Amy felt better about it now too. He couldn't help but step forwards and join in the fuzzy feelings being spread and he peered over Amy's shoulder to look at his little delightfully fluffy son and stuck his finger gingerly out to him, a gesture to which the little baby Werehog responded by trying to bite it and gnawing at it with his little toothless gums.

While Boost was preoccupied with trying to bite his father's finger, Amy looked up at Tails and asked one final question:

"Umm, will Boost turn into a Werehog every night?"

The twin tailed fox teen scratched lingeringly at his own head, clearly thinking about how to answer that inquiry. It was certainly a possibility and he couldn't even think about lying to Amy because —as was just demonstrated— a mama bear could be a terrifying thing to think about. It made him break into a cold sweat just thinking about it. He used his fingers to comb through his own yellow-furred bangs and cocked his head with his blue eyes gleaming with thoughtfulness.

"For the rest of his life it's a likely possibility. The Dark Gaia stuff that was passed on from Sonic has probably bonded with his own anatomy..." He shrugged his arms "But because he is Sonic's son we can't know."

Sonic chuckled light-heartedly (with a hint of anxiety) and he tickled Boost behind the ear and started to make the teeny pup giggle and squeal out of pure joy. He watched as Amy redirected her gaze back down at the baby and it made his own heart become brighter than the volcanic and wild flames of the sun. A big smile spread across his peach muzzle and his heroic emerald eyes practically gleamed with that same old confidence and pride.

He finally spoke after several moments of silence and grinned even wider while Amy passed the Werehog over to him. Sonic couldn't help but be happy while he cradled his son in his arms to calm him down from being so hyperactive, he watched as the pup's curious green eyes started to droop.

"As you said, Tails, Boost's my son and I know that even if he turns into a Werehog every night than he'll be strong enough to overcome it..."

Boost fought to keep his eyes open but he seemed to give in quite quickly as he placed his little thumb inside his mouth and closed his sleepy little eyes, he fell fast asleep in the hedgehog's kind and tender arms; Sonic readjusted the sleeping baby in his arms and lifted him up high so he could softly bow his head and he placed a little kiss on his fuzzy forehead.

"...and I know that he'll make me proud."

A/N: This is the end of my Sonic two-shot.

Now we know why Boost turns into a Werehog and now Sonic and Amy have a lot more to deal with as parents. But we know that our heroic speedy hedgehog and our lovely hammer-happy hedgehog can deal with it together as a team.

I hope that you guys enjoyed this little two-chapter story and I hope that you take the time to review and favourite this.
