A/N: Hey guys the CyberWolf here, bringing you a brand new PAW Patrol AU story titled "Canine Special Investigation Unit" This idea actually came from a roleplay I was doing. Anyways, enjoy the prologue to the story.

CSIU Prologue.

Hello my name is Marshall, the firefighter and EMT of the PAW Patrol and second-in-command of the Canine Special Investigation Unit. What's that you ask? Well, its basically the Spy version of the PAW Patrol. Well, I guess the best thing for me to do is to explain how the CSIU got started. It all started three years ago….

~Three years earlier, Marshall's POV~

Things started out as any normal day for the PAW Patrol. Chase yelling "WAKE UP PUPS! Time for Breakfast!" at eight o'clock in the morning sharp. Chase always would wake us all up at eight o'clock sharp because by then Ryder would have our breakfast ready. Unless we had a late night emergency, which did happen occasionally. Anyways, as I said, Breakfast was normally ready by eight am every morning.

After breakfast, the pups and I decided to do a tournament of our favorite game, Pup Pup Boogie 2. By the time the tournament was over, it was nearly 12 pm, which is our lunch time. But then we all heard our pup tags beep and Ryder's voice came through. "PAW Patrol to the lookout!" We all ran into the elevator but somehow I managed to trip over a bean bag and crash into Chase. "Oops sorry Chase. I guess I accidentally spilled the beans" As usual everyone always laughs at my corny jokes. We make it up the elevator and we stood in line.

"Ready for action Ryder sir." Chase said.

"Thanks for coming so quickly pups. Today's mission is not a really emergency. Today-"

BOOOOOOOM!

A huge explosion could be heard from the Lookout Tower.

"The hell was that?" I yell extremely loud.

Ryder brings down the periscope and looks over at City Hall. "Shit not good! City Hall's been bombed!"

"Whaaaaaaaa? Who would do such a thing?" I said shocked.

"I don't know Marshall, but we are needed at City Hall to verify the death toll." Ryder said.

"D-d-death toll?" I asked nervously.

"Yes Marshall, we have to see how many people died from the explosion."

"Oh right and there might be injured people as well?" I ask.

"Yea good point Marshall. I want you in your EMT outfit for this." Ryder said.

I nod as I get into my EMT Outfit. "I'm fired up Ryder."

"I need all paws on deck. PAW Patrol is on a roll" Ryder said as he slid down his fireman's pole onto his ATV.

I ran to the slide and slipped onto it. Chase and the others followed behind me.

Several minutes later we arrived at City Hall and the sight that greeted us was….horrible. Bodies everywhere. Blood all over the ground. Debris was everywhere from the explosion. We split up and started searching for survivors but after fifteen minutes of fruitless searching, we came up negative. But one thing that will always stand out from this sight in my mind is when we found the Mayor's and Chickaletta's dead bodies. Many questions were running through our minds like 'Who would do this and why?' But no answers came. All we could think of is who is going to run Adventure in Mayor Goodway's place.

The ride back to the Lookout was silent and we all knew what was coming. Ryder was going to have to be Mayor of Adventure Bay and therefore leave the PAW Patrol thus disbanding it. To be honest, I was sad to think that would happen but with the death of the Mayor, we really don't have a choice.

We arrived back at the Lookout and followed Ryder inside without saying a word. Ryder had us go up to the top of the Lookout for the last time.

"Pups we had a great run. These past few years were some of the greatest. Getting to watch you guys grow up together and work together as a team, it made me happy to watch as each of your friendships grew. You are the greatest pups I could have ever had the honor of working with. But now that Mayor Goodway has been murdered, I have to step in as Mayor of this city. This is not easy for me to say, but as much as I want to continue the PAW Patrol and lead it, I can't if I'm running the city. So it is with heavy heart that I say this. From this day forth, I hereby disband the PAW Patrol. Maybe one day, we can restart it up again." Ryder said. "You may keep your vehicles and pup tags to keep in touch with one another. I wish you guys luck in your lives." Ryder said as he went down his pole one last time.

Only thing that went through our minds after that day was revenge. We were going to find the ones responsible and bring them to justice. No matter what, we WILL have our revenge.
