Dubai, United Arab Emirates, July 3, 2012.

I was sitting on the front steps of the tallest building in the ruined city of Dubai, looking at the ground blankly and holding an AA-12 automatic shotgun.

For those of you who are wondering who I am, my name is Martin Walker, Captain of the United States Army's 1st Special Forces Operational Detachment-Delta, or more commonly known as Delta Force.

Speaking of Dubai, you probably saw in the news about the unexplainable sandstorm that has engulfed the entire city and cut off communications to the outside world. In the F.O.B. where I was stationed, some of my fellow brothers and sisters in arms actually believed that the sandstorm was an act of God meant to punish all of animal kind for our arrogance, but I didn't give a shit at the time. When the storm first began, the 33rd Infantry Battalion was sent in to help with evacuations, limited communications from the 33rd through the first week reported bizarre conditions including large amounts of electromagnetic interference within the storm, and it appeared the storm was at least two miles thick before communications were lost entirely. Colonel John Konrad, leader of the 33rd had recommended that no other units be sent until they could get through to the city itself and determine conditions within. For the next several weeks, specialists in many fields monitored and tested the conditions they could see, trying to determine the source of the phenomena and document anything that could give them more information about what was happening, while they waited for more information from within.

After several weeks of this scientific exploration, a radio technician stumbled across a very faint message from Colonel Konrad that had somehow managed to get through the interference from the storm, stating that they were attempting to leave the city with some survivors. Nothing else was heard for months until another faint message from Konrad was detected that gave little information besides the complete failure of any evacuation. All we knew was that the 33rd Infantry had dissolved and whatever terrible conditions existed within the sandstorm, Konrad blamed himself and held his men blameless of whatever had happened.

The reason I'm here in this hell on earth, is that Delta Force had been activated shortly after the final distress call had been received. After establishing our FOB, and waiting for almost two weeks, we finally received orders. First Lieutenant Alphonso Adams, Staff Sergent John Lugo and I were ordered to simply recon the inside area and report back, nothing else. Personally, I wanted to rescue any survivors we could find along the way. After nearly two days of struggling through the still raging sandstorm, we finally broke through to the inside. When we entered the ruined city, we encountered hostile refugees and things went tits up from there. The things I have seen and done, the horrors I have experienced, words cannot describe. I have committed many horrific atrocities that would get me sent to prison for war crimes. But one of the worst things I have done was to launch White Phosphorus on the remains of the camp of the Damned 33rd, only to find out too late that there had been many innocent refugees in the now destroyed camp.

I was trying hard not to gag at the awful stench of cooked flesh and burnt fur while Lugo, Adams, and I were walking through the camp. Rogue soldiers of the 33rd were screaming and howling in agony while the Willie Petes burned them from inside out. Humans, jackals, lions, foxes, and wolves reached out to us and begged for us to kill them.

"This...this is too much..." Lugo stated as he looked around in horror.

"Stop talking," I warned.

"What did you just say?" Lugo inquired.

"He means the smoke is toxic, so keep your mouth shut," Adams notified him as we kept walking through the once beautiful plaza.

"Yeah, right...Jesus," Lugo mumbled bitterly.

"Let's just keep moving," I said, wanting to get away from all this carnage.

"Walker...come on, man" Adams protested as we kept walking past people who were suffering in an agonizing way.

"There's nothing we can do. Come on, he's already dead," I snapped in irritation as we passed a jackal that was crawling and reaching out to us until he slumped onto the cracked pavement.

The three of us jumped down into a depression where the street had torn apart from an explosion and walked over to a charred and dying soldier that was wheezing out his last breaths.

"Why?" the fox gasped out.

"You brought this on yourself," I stated coldly.

"We were helping..." the fox trailed off as he pointed to our right and died.

"What?" I questioned in confusion.

When I looked to our right, my eyes widened in horror and I said, "Oh no..."

What I saw when I walked over was piles of dead refugees that were in poses of agony. I just stared as Adams and Lugo followed, but what truly broke me was seeing the bodies of a woman and her child sitting and holding each other close in death.

"Are those...civilians?" Lugo was barely able to say, sounding like he was unable to process what he is seeing as we slowly walked into the horror.

"Where'd they come from? There's no camp here!" Adams questioned in shock.

"They took 'em from the nest..." I trailed off as I stopped walking and my mental state started unraveling.

"That hotel back at the storm wall?! No, no, no. No, those can't be the civvies that got kidnapped. It's not possible!" Adams exclaimed in denial.

"Yeah, it is. It's why Gould stormed this place. He didn't want The Gate, he was tryin' to rescue his people...this is your fault, Goddammit!" Lugo yelled at me in rage, but it sounded muffled to me.

"Stop right there, Lugo," Adams warned.

"But it is! He wouldn't listen!" Lugo protested.

"We didn't have a choice!" Adams argued loudly.

"He turned us into fucking killers!" Lugo roared out in despair.

"That's enough, Sergeant!" Adams shouted.

"No! No!" Lugo screamed uncontrollably and hysterically.

"Control yourself, now!" Adams yelled as I snapped out it and turned around.

"We need to keep moving," I said blankly.

"What?!" Lugo inquired.

"Reinforcement will be here any second- we need to keep moving," I stated.

"But, Walker...you're not...you're not even-" Adams tried to protest, but I cut him off.

"I'm gonna make these bastards pay for what they've done. Now, are you with me, or not?" I asked darkly.

Adams and Lugo moved ahead and I followed them away from the horrific sight until we were spotted by survivors.

"There they are! Murderers!" a human roared out in rage and started shooting at us.

After that incident, I eventually found a radio and made contact with Konrad as we moved on. We fought through pure hell along the way and I lost Adams and Lugo in the process. Lugo was captured by enraged refugees who hanged him from a streetlight and hurled insults while he kicked and gasped for breath. When Adams and I came upon the scene, I shot through the rope and in my grief, frantically began CPR while Adams held off the crowd. When I was unable to revive him, I just snapped and opened fire on the refugees. Adams and I slaughtered everyone in our line of sight until no one was left alive. Adams died as we were attacked while trying to gain entrance to the building where Konrad had been hiding. I wanted to make that monster pay for everything he had done, but when I entered the building and found Konrad, I discovered the horrifying truth. The Konrad I had been talking to was nothing more than a hallucination brought on by my shattered mind because I was unable to cope with what I had done and I needed someone to blame. After that shattering realization, I managed to find a working radio and sent out a distress call to command. I had been waiting for days for the rescue team, when the raging sandstorm suddenly stopped. Tons of sand fell to the ground and it began to rain. I assumed that if the storm had stopped, a rescue unit would now be able to get in and find me, so I continued to wait.

I looked up when I finally heard the sounds of vehicles approaching. I saw two U.S. Military Humvees pulling up and eight Marines consisting of two foxes, three dogs, and three jackals got out and took up positions around me. I slowly stood up and started walking to the Marines lifelessly as one human soldier got out of one of the humvees and began speaking into his radio.

"Commander, this is Falcon-1. I think we found him. Captain Walker?" the soldier inquired to me.

"He's armed!" one soldier notified in alarm.

"It's okay, hold your fire!" the lead soldier, who was a Sergeant, reassured.

"I don't understand...what's he doing?" a soldier asked in confusion when he saw me stop and stare at them unnervingly.

"Look at his eyes, something's not right," a soldier stated uneasily, and I knew he could see that I looked disheveled and unshaven, my uniform and Konrad's uniform jacket were in tatters, and I had a dead look in my eyes. I also had many scars all over me, the most prominent one being a large, horrifying burn scar that was on the right side of my head and face.

"Captain Walker, we are here to help. But first, I need you to lay down your weapon," the Sergent said carefully as he approached slowly and cautiously.

"He's not complying," a soldier informed his Sergent.

"He's shell-shocked, give him a second! Just hand me your weapon, Captain. We're here to take you home," the Sergent reassured.

"Can he even hear you?" a soldier commented, making the Sergent shoot a look at him before he looked back at me.

"Captain?" the Sergent asked me hesitantly.

I hesitated because I truly didn't know what to do. I wanted to shoot myself because I wanted to die for what I had done in this hellhole, but I thought about my brother Nick, my wife/mate Katherine, a timber wolf, and my kids. I knew that they were waiting for me to come home, and killing myself would be selfish. I lowered the shotgun and the Sergeant gently took it out of my hands.

"It's over. Time to go home," I thought as the Sergeant led me to one of the humvees and we all drove through the destroyed city.

"You know, Captain...we drove through this whole city to find you. We...saw things. If you don't mind me asking, what was it like? How did you survive all of this?" the Sergeant questioned in slight astonishment.

"Who said I did..." I trailed off hauntingly while looking out the window.

After we arrived back to base, I was checked out by a doctor. When he okayed my physical condition, I was led to a psychologist. After a mostly one-sided conversation, the counselor informed my superiors that in his opinion, I was mentally unfit for duty. Within a few days, I was honorably discharged and sent home to Zootopia, which was my hometown in the United States.

After leaving the military base airport, I took a train to Zootopia. When I arrived at the station, I carefully avoided many animals, humans, and the much larger animals like polar bears or giraffes. Then I saw my brother, a red fox with an auburn tip on his tail who was wearing a tacky green Hawaiian shirt, a dark indigo necktie with red and blue stripes, sunglasses, and brown pants. I know you're wondering how a human could be related to a fox. When I was five years old, my biological parents died in a car accident and Nick's parents Johnathan and Francine Wilde, good friends of my parents, adopted me and raised me like I was one of their own. When Nick saw me, he let out his trademark sly smirk and walked over to me.

"Well, if it isn't my 'one day older than me' brother... How are you...doing..." Nick trailed off when he lowered his shades, and his eyes widened in horror when he saw my burn scar.

"Hello, little brother," I greeted blankly, staring at him with a dead expression that appeared to make Nick uneasy, but he managed to put up his sly front again.

"So, Finnick's waiting for us outside," Nick notified me and we started walking out of the train station and found ourselves at an alley until I saw Finn's van that had interesting artwork on both sides of it and I saw Finn himself, who was a fennec fox that was dragging on his smoke.

"Hey Finn, look who I found wondering inside the train station!" Nick announced as we were approaching him and Finn normal scowl changed to a grin when he saw me.

"Well Goddamn, if it isn't Martin fucking Walker himself. Welcome home Kid," Finn greeted as he threw down his cigarette butt. But when he lowered his shades to get a better look at me, his eyes widened when he saw my burn scar.

"Hello Finn," I responded blankly.

"Well, how about we get you home, okay?" Nick said as Finn got into the van and started it.

Suddenly, I heard a gunshot and the next thing I knew, I was back in Dubai with bullets flying around me. I immediately took cover at a burned out car and I noticed that I didn't have my M4A1 carbine rifle and M9 sidearm.

"Adams, Lugo, lay down suppressive fire! I need to find a weapon!" I ordered as I kept my head down, only I didn't see my men anywhere.

Suddenly, someone grabbed my arm and without thinking, I threw the person up against the car and started choking him.

"Kill is fucking confirmed!" I roared out in pure savagery until something cracked hard against my head, and everything went black.

Finnick held the baseball bat above his head again as Martin crashed to the ground unconscious while Nick was holding his throat, coughing and hacking harshly.

"You okay, Kid?" Finn asked while he still kept his eyes on Martin, wondering what the fuck just happened.

"Yeah...I'll be fine...It's not the first time this happened to me," Nick reassured.

"Good...now what the fuck just happened?! I heard Martin yelling, and I came out to see him trying to kill you!" Finn questioned in disbelief.

"I don't know...when your van backfired, he just completely lost it and acted like he was getting shot at by someone. When I grabbed him to try and calm him down, he threw me up against the van and started choking me. It was like he didn't even recognize me," Nick explained while he was rubbing his neck.

"Well...let's tie him up so that he doesn't hurt anyone or himself," Finn said as he was putting the away in his van and grabbing rope.

"Finn...are you sure? Because it didn't look like Martin knew what he was doing," Nick asked while Finn was tying up Martin.

"It's like you said Kid, he wasn't aware of what he was doing. This is for his safety as well as ours. Help me get him inside," Finn stated as he struggled to lift Martin. But due to his small stature as a fennic fox, he wasn't having much luck. Nick walked over and the two of them managed to get Martin into the van and they got in.

As Finnick was driving to a inconspicuous location, Nick looked at his brother in concern, recalling the insanity that was in Martin's eyes as he was trying to kill him, and he shivered as he remembered the dead expression in Martin's eyes when he got a good look at his brother and the large horrible burn scar that was on the side of his head. Nick recalled all the times he and his brother would successfully pull off cons and that they swore to each other when they were kits that it was them against the world, and they would always look out for each other, no matter what. At that point, Nick knew that the brother he knew since he was a kit, had died and a stranger had taken his place.

"What the hell did you see over there, Marty?" Nick thought with his ears lowered, unable to imagine what kind of horrors his brother had seen.

Suddenly, Martin started groaning, and Nick tensed while Martin started to regain consciousness.

I groaned as I was waking up, feeling like someone tapdanced my head with a baseball bat.

"Are you okay, Martin?" Nick's voice rang out in concern, and I noticed that my arms and legs were tied up.

"Fuck...Nick, why am I tied up? Who the hell hit me?" I questioned in pain.

"Yeah, sorry. That was Finn. He knocked you out because you just lost it and tried to kill me," Nick explained.

"Oh God...I tried to kill you?! I don't remember that! What the fuck did I do?! Please...I need help..." I trailed off while I was sobbing, letting out all of the trauma I've experienced.

"It's okay Marty...we'll get you help," Nick vowed as he untied me and held me in his arms while I was breaking down uncontrollably.

"I killed them...I killed them all...it's all my fault...it's all my fault! I have blood on my hands!" I babbled brokenly while Nick was looking at Finn, who was staring back in the review mirror in concern.

A/n I know what you are thinking, the human in Zootopia thing has been done before, but I'm doing things a little bit differently. See, this crossover takes place in a world where humans evolved along with animals, and the world history is the same as human history, with the exception of the destruction of Dubai. I just wanted to warn you that there are concepts of a combat veteran struggling with a bad case of post traumatic stress disorder and having a rough period of adjusting to civilian life. Well, if thats all, let me know what you think about this story by reviewing.
