Hulk vs. Wolverine: Sonic Style

Shadow's POV

My name is Shadow the Hedgehog and I am the Ultimate Lifeform. I was created by Dr. Gerald Robotnik as Earth's protector and became best friends with his granddaughter Maria. I'm the best there is at my job, and that's being a maverick and the best damn mercenary ever. But what I do in my job, isn't very nice and even the Ultimate Lifeform is pushed to his limits by one of his greatest rivals. Especially when your greatest rival is also your foster brother.

Welcome to the deep forests of Canada and I'm slowly waking up. I opened my red eyes to see myself in the center of a huge crater. I slowly pull myself up off the ground, blood dripping from my mouth and hitting the ground. How the hell did I ended up in this crater and why do I have a dislocated shoulder? I used my left arm to try and pop my right shoulder back into place and I finally popped it back, causing myself to scream in extreme pain.

"Aaaaahhhhh!" I screamed in absolute pain. After I finished screaming in pain, I cracked my neck and my fully healed shoulder. I moved my right arm around to stretch my shoulder until the pain is gone. I picked myself off the ground, dusted myself off, grabbed my dual pair of Sai near the crater, and closed my hand back and forth.

"Oh man. What the hell happened?" I asked myself. Just then, a loud roar was heard in the distance and I looked up at the cliff above me. Suddenly a giant figure jumped off the cliff and came crashing to the crater. I ducked away in time to finally see the figure; it was a giant blue hedgehog/werewolf hybrid. The blue hedgehog/werewolf hybrid was shirtless while wearing a pair of ripped blue jeans and red Converse sneakers.

"Raaawwwrrr!" The blue hedgehog/werewolf roared at me.

"Oh yeah." I said to myself. Now I remember what happened and who the blue hedgehog/werewolf in front of me was; my foster brother Sonic the Hedgehog.

Normal POV: Four Hours Earlier

A military helicopter was arriving to the town of Elkwood, Quebec Canada; carrying a soldier and Shadow inside. The soldier nervously looked at the black hedgehog sitting across from him in his black jeans, a white Nike sweatshirt, a black Jordan jacket, a black beanie, and his pair of red/white Nike Air Max hover shoes.. Shadow had his eyes closed and was relaxing in his seat until the soldier spoke up to him.

"I don't mean to be rude, but what are you?" The soldier asked nervously. Shadow opened his eyes to take a quick glance at the soldier before closing his eyes again and answered the soldier.

"Something you don't need to know chump." Shadow replied in a low voice. The soldier didn't say anything else as the helicopter safely landed in Elkwood. Shadow exited the helicopter to see the town of Elkwood in ruins. He walked to meet a Canadian soldier as the helicopter returned to base.

"Looks like someone was pissed off today." Shadow said seeing the town in destruction. Shadow and the Canadian passed through destroyed vehicles, homes damaged in flames, and paramedics tending to injured citizens.

"It happened four hours ago. The creature was spotted in Elkwood and as you can see, this is the result of its destruction. The Americans called the creature Wolf." The Canadian stated. Shadow stopped by an abandon car to see a teddy pair in the back seat. Shadow closed his eyes and used his high senses to produce a vision of the events. After taking a few deep sniffs, Shadow opened his eyes and made an astonishing discovery.

"I smell morphine and gunpowder. Someone or a group tried to fight back." Shadow said kicking away broken glass and rubble to see the Elkwood sign surround in gun shells.

"They didn't fight hard enough." Shadow stated.

"GUN and Agent Topaz sent you hear to stop Wolf. And if you can't stop Wolf, feel free to kill it." The Canadian stated. Shadow just smirked at the Canadian after hearing that he can kill the creature.

"Sounds like a good day to me." Shadow said with a smirk. A short time later, a military airplane was flying over the mountains of Canada. Shadow was in position to fly out of the cockpit; the only weapon he had was his dual pair of Sai. The pilot opened the cockpit for Shadow to see a huge crater in the snowy mountains.

"This is the drop off Shadow." The pilot said.

"Thanks." Shadow said. Shadow jumped out of the plane and was free falling into the snow-covered mountains. Shadow landed safely in the snow and began his search for the creature known as Wolf. Shadow searched the entire forest and mountains, but he could not find the creature. After searching the entire area, Shadow was at waterfall taking a nice break and replenishing his body with much needed water.

"Damn. I can't find this bastard." Shadow said taking a drink of water. He looked over to see a grey wolf take a drink of water next to him. Shadow kindly pet the wolf's head and watch leave into the woods. Just then, a loud thump was heard from the mountain and birds flew out of the trees, catching Shadow's attention. Shadow walked up the mountain and saw a clue in the snow.

"Footprints." Shadow said. Indeed, they were footprints, but they were double the size of Shadow's Air Maxes. Shadow followed the footprints in the snow and saw the prints shrink in size until they were the same as Shadow's shoes. The black hedgehog heard heavy breathing behind a huge boulder and hid behind it. Shadow peered his head around to see the source of the heavy breathing; it was his foster brother Sonic sitting on a log.

"What the hell?" Shadow quietly said in confusion. The black hedgehog slowly walked up to Sonic and saw that was in nothing but his ripped jeans and red Converse sneakers. Shadow wanted to know what happened to his foster brother and spoke up to him.

"Sonic?" Shadow asked catching Sonic's attention. Sonic looked around and gasped in horror once he saw Shadow.

"Shadow! Stay back!" Sonic said quickly standing up.

"What?" Shadow asked approaching his foster brother.

"Stay back now!" Sonic said backing up to a boulder. Shadow saw Sonic cringed in fear, but that didn't stop him from helping his brother.

"Look Sonic, I'm not going…" Shadow didn't finish as he sniffed Sonic and found a scent; morphine.

"You smell like morphine!" Shadow said grabbing Sonic's head. Sonic was tossed to another boulder and slammed by Shadow, who was now angry.

"What happened Sonic?!" Shadow asked in anger.

"Please Shadow, you don't understand." Sonic begged. Shadow didn't listen and pulled out his Sai, which he held at Sonic's neck.

"I'll cut your throat Sonic if you don't give me answers." Shadow angrily demanded. Sonic began to shake violently and his eyes turned from emerald green too dark green. The next thing that happened was Shadow being slammed into a tree. Shadow slowly got up to see Sonic grow in size, his fur turning dark blue, his teeth becoming serrated, and unleashing razor sharp claws. It had happened, Sonic had turned into his werehog form Wolf; startling Shadow.

"Rrraaaawwwwrrrr!" Sonic roared into the forest. Sonic now stalked Shadow, who was standing his ground in both shock and surprised.

"Ah shit! Hey bro, can I just say I'm sorry for pissing you off." Shadow said. Sonic's response was delivering a powerful uppercut, sending Shadow flying in the air.

"Aaaahhhh!" Shadow screamed as he landed hard to the ground. That is how the story began and now we are back to the beginning. Sonic roared at Shadow, but the Ultimate Lifeform wasn't going to back down from a fight.

"Alright Sonic, let's fight!" Shadow said pulling out his Sai. "Come on!" Shadow egged on. Sonic roared at Shadow and slammed the ground, causing the cliff to completely break. Sonic and Shadow ended falling into the lake below after the avalanche. The two brothers fought in the water until Sonic once again delivered a powerful uppercut and sent Shadow flying in the air again.

"Aaaahhhh!" Shadow shouted as he landed hard again. Sonic slowly walked out of the water and began to leave, until Shadow jumped off a rock and stabbed his Sai into Sonic's back.

"Rrraaawwwrrr!" Sonic roared in pain. Shadow continued to deepened his Sai into Sonic's back, until the werehog slammed Shadow into a boulder. Shadow quickly recovered to see Sonic throwing giant rocks at him. Shadow dodged each one of the giant rocks and ran to Sonic, until the werehog slammed a huge boulder onto the black hedgehog; knocking him out.

"Rawr! Wolf smash Shadow." Sonic roared. "Shadow leave Wolf alone!" Sonic roared again as he punched the wounded Shadow. Sonic continued to punch Shadow into the ground until he couldn't move anymore. "Wolf is strongest ever!" Sonic roared as he delivered one final punch.

"Rrraaawwwrrr!" Sonic roared one last time. The werehog was breathing heavily as he walked away from the beaten Shadow. Sonic was still breathing heavily that he didn't the sound of rubble moving. He turned around to see Shadow back on his feet with blood dripping from his mouth.

"Okay Sonic, it's time round two!" Shadow said with an evil smile. "Aaaahhhh!" Shadow roared charging at Sonic. The Ultimate Lifeform pounced on Sonic and repeatedly stabbed his chest, hoping to weaken Sonic. Sonic shook off his foster brother and the two warriors fought each other in an evenly match fight. The fight continued until Shadow stabbed Sonic until he was down on one knee. The two brothers were breathing heavily as Shadow stood tall over Sonic.

"I'm sorry Sonic." Shadow said. Shadow held his Sai above the wounded Sonic, intending to deliver the final blow. Suddenly, poison tranquilizer darts were fired at Sonic's back; causing him to succumb to the poison and pass out. Shadow was then hit by the darts as well and fell onto his knees from the poison. Shadow had enough strength to see who shot them; it was Sonic's anti Scourge the Hedgehog.

"Thanks runt. We've been trying to catch him all day." Scourge evilly said. Right behind Scourge was his crew of mercenaries; Jet the Hawk, Metal Sonic, Fiona the Fox, and Cyo the Lion. Cyo happily waved at Shadow, who was slowly succumbing to the darts poison.

"Shadow buddy, it's me Cyo. I shot you." Cyo said one last time as Shadow passed out. Shadow had a dream about his past; you see Shadow was a former member of Scourge's crew, who were working with the mad scientist Dr. Warlock. He learned that the crew were going to turn him into a living weapon with no memory at all. Shadow betrayed them, ripped off Dr. Warlock's right hand, slaughtered the guards, and escaped into a snowstorm. He was eventually taken in by Sonic and his friends and never left ever since. He was woken up by Scourge punching him repeatedly.

"Wake up asshole." Scourge said. Shadow woke up to see he was strapped to a wall inside the same lab he was nearly turned into a living weapon. Cyo was also in the room twirling a poison dart in his fingers; the young lion was a good guy, but if the paycheck is fat then he'll become bad.

"Shadow buddy. We missed you." Cyo said. "The place hasn't been the same without you. Jet is a bed wetter and Metal Sonic is very lonely." Cyo happily said. Just then, the automated doors opened and Metal, Jet, and Dr. Warlock entered the room. Dr. Warlock was now sporting a metal claw hand as he approached his former mercenary.

"Do you ever shut up Cyo." Jet angrily said.

"One day, Metal will rip off your tongue." Metal Sonic said in third person.

"He's very self-conscious." Cyo whispered to Shadow. Dr. Warlock finally stopped in front of Shadow with Jet, Scourge, and Metal Sonic standing next to him.

"Despite Cyo's greed, Warlock Enterprises has missed its top operative." Dr. Warlock said with a smirk. "Thank you for leading us to your foster brother Sonic. Better known by his alter ego, Wolf. Of course if you've arrived earlier, the town of Elkwood would still be in one piece." Dr. Warlock stated.

"I shot him in the ass with one of these." Cyo said pulling out his gun. Scourge, Metal Sonic, and Jet gave the young lion annoyed expressions before turning back to Shadow.

"What I did." Cyo reiterated.

"What do you plan on doing to Sonic?" Shadow angrily asked.

"We just want him to find his happy place. I mean did you see how angry he was…" Cyo didn't finish as Metal Sonic grabbed him by his throat, choking him.

"We want what we originally intended to do with you Shadow; turn Sonic into a living weapon. I'll erase Sonic's memory along with yours and I'll finally have the most dangerous creatures at my disposal." Dr. Warlock stated. Shadow angrily stared at his former boss as realization hit him; Sonic transformed into Wolf to protect the town from Scourge's crew who were hunting him down.

"You should have killed me when you had the chance." Shadow said with anger flowing through his veins. "Because once I get out of here, I'm going to kill your boys and I'm going to personally rip your heart out." Shadow finished. Dr. Warlock was startled by Shadow's words but smirked at his former mercenary and spoke up again.

"Shadow please. Once I'm done with you, you won't remember anything." Dr. Warlock smirked. Just like that, Dr. Warlock exited the room to leave Scourge, Metal Sonic, and Jet to talk to Shadow.

"The doc might want you as a weapon, but what's stopping us from killing you." Scourge said leaving the room.

"Damn right Scourge." Jet stated following the green hedgehog. Metal Sonic still had Cyo in his grip as he took once last look at Shadow and released his grip.

"Oh shit, I hate when Metal does that." Cyo said catching his breath. The young lion looked up at the trapped Shadow and smiled at him.

"Oh don't be sad Shadow." Cyo said approaching Shadow. "If it makes you feel better, Fiona tried to kill you earlier." Cyo happily stated while pulling out his Desert Eagle.

"Guess it's better than having to listen to you talk shit." Shadow said.

"Personally, I like you. The others hate you, but Fiona really hates you. I mean I don't blame her after you betrayed us." Cyo said twirling his Desert Eagle.

"At least I'm still loved by your smartass." Shadow sarcastically stated.

"Yeah I know." Cyo said. "Hey, you still have that unbreakable skull?" Cyo asked. Shadow just smiled as Cyo aimed his Desert Eagle at his skull and pulled the trigger. The next sound that was heard was the bullet ricocheting off Shadow's indestructible skull, saddening Cyo.

"Damn it." Cyo said in disappointment.
