A/N: Been looking at Tik Tok videos of Knuckles. He's hawt! I even made my own Tik Tok account and made a couple of sonic edits, including Knuckles, posting them on Instagram.

Sonic P.O.V.

This was my best day, and being unsupervised was the best. Y/N had such a great time, and we played many games and made a little mess around the place—no big deal. I cleaned up everything so that Tom and Maddie won't notice anything wrong, and they couldn't tell the difference before leaving the house and leaving it clean. I was bopping my head listening to the Backstreet Boys; Y/N and I were talking to learn more about each other. Suddenly, my phone buzzed as I reached down to pick it up out of the water--it was waterproof and had no damage.  

I answered the phone, and it was Tom calling to check on us. I reassured them that everything was fine. He doesn't want any raccoons going through it like last time. 

"Was it Tom?" Y/N asked.

"Yeah. Wanna ensure everything is fine and tell you to take out the trash." I replied. 

"We need to clean up this mess," Y/N said.

"I got it!" I said as I zoomed out of the house to head to the shed and got the lawnmower to start cleaning around the house. As Y/N's jaw dropped. 

I did clean up the house after we made a mess of things, but nothing was broken.

"Wow, I never knew you could use a lawnmower to clean the house. My mom would kill me if I did something like that." Y/N said, looking up at me as I waved off.

"It's nothing. Just don't try this at home." I winked.

Suddenly, the power went out. I was slightly panicked.

"The power is out. Is it a storm?" Y/N asked.

"It might be. I know the satellite didn't come to loss." I said, shrugging my shoulders.

DING! DONG!

"Someone's at the door? Around this late?" Y/N asked.

"I'll go answer it. It might be the pizza I ordered." I said. 

I went to answer the front door and didn't expect to see the egghead standing there. 

"Hello, hedgehog." He greeted them with the most cunning grin ever. "Did you miss me?" He asked. 

Ew. No.

I shook my head, feeling like this had to be a dream, and it wasn't. He was standing in front of the door, looking at me as his eyes were looking down at me intensely. 

"I don't know how you got back, but you made a big mistake coming here," I said, furrowing my eyebrows, not making a move just yet to kick this sucker off my property.

"Oh, confrere mon fraire. The mistake was thinking You won, but that was just the prelude: ordure, apartheid, and a moose bush-- " Eggman said. 

I rolled my eyes. "Alright, I get it." 

He chuckles, shaking his head. "I don't think you do." He frowned as he took a couple of steps forward toward me. "But you're about to, and will that idiot sheriff, his wife," He said as I could feel my power generating within me as I held back my anger. "AND YOUR LITTLE DOG TOO!" 

That was it, and I wasn't going to let him harm my family after he prepared whatever comeback plan he got. Eggman was standing right where I wanted him to be as I leaped into the air, raising a fist to collide with his face. Looking at his mustache ticked me off, but when he moved aside, another person resembling M.E. appeared and drew a hard punch at my face.

"WHOA! Y.A.!" I was punched far back into the wall, broke the television, and crashed on the couch with the girls. 

"Sonic, are you okay? W-What happened!?" Y/N exclaimed. She looked down at me, cupping my cheeks as her eyes changed to purple. 

"I-I'm fine. Someone on the other side K.O. me." I stared at her, so memorized by her beauty that it took over me. "You cute when you worried about me." 

"Sonic, not the time!" She slapped me out of it as I snapped back into reality before looking back to hear heavy footsteps. 

Behind the hole in the wall with the wires hanging out from the sizzling television. The person standing behind the wall was the one that punched me, glaring at me with violet eyes. He had red fur covering most of his body, a black nose on his peach-skinned muzzle, a white crescent patch of hair on his chest, and violet eyes. He also has seven dreadlock-like spines around the sides and back of his head and a medium-sized, tri-crooked tail.

"Pitiful." He said in a raspy voice. 

He came around the corner with Eggman standing in the middle room, and I glared at them.

Y/N looked at me, asking, "Who is he?"

"Yeah, who are you?" I asked.

Eggman peeks through the hole, grimacing, "Where are my manners?" He said as he went around to see us on the couch together.

Eggman smiled, smiling, "Well, I didn't mean to intrude here to see you having a little slumber party tonight." He chuckled deeply, "Sonic..."He pointed over at Y/N, wanting to know her name too.

"It's Y/N." 

"...Y/N...meet Knuckles, my new BFFAE. Bestest friend forever and ever!" He introduced. 

"I can see why his name fits his character," Y/N said.

"Yeah. He's a knucklehead and has a knuckled fist." I commented. 

My head still hurt, and Eggman turned his attention back to Y/N and asked, "Are you reproduced animal like this little hedgy here?"

"I'm new around here," I replied bluntly.

"Welcome to the Green Hills!" Dr. Eggman warmly welcomed them with a fake smile on his face.

I sighed as I hopped off the couch, "Look, Robotnik, I don't care who you brought to help you." I knelt to pick up the sack of rings in my bag to put it around my shoulders. "You're never gonna get my power." 

Knuckles looked at me intensely, piercingly, "Do I look like I need your power?" He asked, holding up his fist that was glowing red.

"Sonic-"

I shook my head, looking at Y/N reaching toward me, and I said, "Stay out of this!" I got into a fighting stance as I charged at the red Echidna, but his fist collided with me, sending a hard punch to get me knocked out of the house.

The girls were standing aside and flopped on the ground covered in dirt. Knuckles jumped out, landed on his feet, and banged his fists together, ready for more. 

Eggman was standing by the large hole in the house, holding a bowl of dipping sauce, "It's so nice when diabolical lives up to the hype." He said, dipping a chip into the sauce and taking a bite out of it.

I grunted as I stood back up, and Knuckles remained his ground. 

"Where is it?" Knuckles demanded. 

I stood up, wiping the blood trickling down my chin, "Oh, you want it? Here it comes!" I charged up my quills which were light blue.

"I was expecting more of you. You're unskilled...Untrained...and unworthy." Knuckles said. 

I got on my knees as I grind my teeth together, "You forgot one. Unstoppable." I dashed straight toward him, hoping that I was going to take him out, but I wasn't moving anywhere. 

Knuckles stopped me from attacking him with a O.N.E. hand. Then, he lifted the fist and smashed me into the ground, creating a massive explosion while Dr. Eggman was eating popcorn. The girls ducked behind so they wouldn't get hit by force. I was lifted but grasped by the neck and pinned against the tree. 

"It is my destiny to do what my ancestors could not. To restore the ultimate power to the home of my people." Said Knuckles.

"Ultimate power? I don't know what you're talking about." I said. I grunted, struggling under his grip. "You've got the wrong guy." 

Eggman tilted his head, interested in learning about the mysterious power that Knuckles was talking about.

"Ultimate power? You're speaking my language." Said Eggman.

"Don't play dumb with me. Apprentice of Long Floor." Said Knuckles.

"You mean Long Claw?" I asked.

"Long Claw and her people were sworn enemies of my tribe, the Echidna. We fought and died at their hands. Now so are you." Knuckles was about to punch me until I saw a police car appear. Knuckles got hit by it and crashed into the garage.

"GET IN!" I saw a fox that had blue eyes and yellow fur. 

I turned towards the house and shouted, " Y/N Hurry!" I saw them peek around the corner as she ran towards the car vehicle to get inside, and I got in the front as we drove off quickly.
