Hey guys, so I got this idea off a meme I saw but can't link you to. Sorry, but this is about Halloween in Central and Starling city, where the Flash and the Arrow get the ideas to trade costumes and identities for Halloween, and soon, other heroes and villains start to play along! Leave requests for who you want to see as who, and without further ado, here is Oliver as the Flash...

My name is Oliver Queen. I agreed to this for some reason, and it turns out that STAR labs is super creepy. I guess I'm just not used to working above ground.

Barry's suit is actually really skinny. That kid can move at supersonic speed in it, and I can barely touch my toes. I just hope that my costume is causing him just as much pain. In addition, that weird kid with the long hair and the nerd shirts keeps asking me for an autograph. I gave him one, and then he asked for two, one from Oliver Queen, and one from the Arrow. Then, he asked for one from the Hood, the Emerald Archer, and one from my true persona which he called, 'Oliver Quarrow.'

"Okay, you'll be able to hear us through the earpiece." said Caitlyn. She was the one who handled the medical things at STAR labs, and Cisco, the weird kid with the long hair, created the suit and gadgets. Along with them were Ronnie and Dr. Stein, who only had powers when they were fused together. Detective Joe West was with us as well, who thought his was a bad idea and as massaging his temples in the corner. Barry was in Starling city right now, and it was up to me to keep the city safe in his super tight suit with lightning bolts on his ears.

"Ronnie and Dr. Stein will be out there with you." The weird kid with the long hair said. "We'll be able to track anything that happens from here. Now for the piece de resistance." He handed me some gold shoes that I slipped onto my feet. They were the only part of my costume that fitted.

"Those will give you Barry's super speed for one hour." he grinned proudly. "I had them developed in case Barry ever needed a speed boost."

"Why don't you use these all the time?" I asked.

"Eh, there are some bugs. Besides, they're really expensive, and if you damage them, I will come after you," he then remembered who I was and looked down, embarrassed. "Mr. Arrow."

There was a beep from the computer, and Caitlyn looked down to see what was happening. "We've got a disturbance. Captain Cold and his rogues were spotted at the Central City Bank. You'd better get over there."

Dr. Stein and Ronnie faced each other, both glowing with white-hot energy. In an explosion of heat, the two merged together to become Firestorm, and faced us. "Let's go." He (or they) said.

I rubbed the shoes against the floor, seeing the electricity spark off of them. It surged through my body and I felt the lightning in veins. In a flash, the world zoomed past me, and I found myself running into the door of STAR labs, falling onto the floor. It was at least a good thing that those lightning bolt things were on the sides of my head and not on top, because that would've really hurt me.

Ronnie (I will henceforth refer to Ronnie and Dr. Stein as just Ronnie,) helped me up, and the weird kid with the long hair recalibrated the shoes, and soon I was off to the bank.

In the blink of an eye, the world zoomed by and I was in front of the bank. I was beginning to see why Barry liked doing that. I walked into the chaotic setting at normal speed to find the criminals shooting up the place with their guns. I knew them. ARGUS had been trying to catch them for ages.

Leonard Snart, AKA Captain Cold, had frosted the door shut so there was no way in. He was now counting the money he had stolen from the vault. His accomplice, Mick Rory AKA Heatwave had rounded up some guards and was holding them hostage with his heat gun. Snart's sister, Lisa Snart AKA Golden Glider, was harassing a bank teller.

I had to move quietly and quickly so they wouldn't shoot the hostages. Unfortunately, my partner did not have the same level of restraint. He yelled, "Flame on!" which seemed familiar for some reason, and blew the door open in a burst of white-hot fire. The criminals noticed us.

Captain Cold, Heatwave, and Golden Glider fired their guns at us simultaneously, being countered by Ronnie's bursts of fire. I used the distraction to slide across the floor and untie the hostages, letting them run free.

"Time out!" Cold yelled, making Ronnie and his accomplices stop the firing. I turned over and saw he was staring directly at me.

"Flash," he said, walking over to me slowly. "Did puberty come late for you, or what?"

I didn't know what he meant until I remembered my manly, stubbly complexion showing through the mask in contrast to Barry's baby-smooth chin.

"I am the Flash." I said, trying to mimic Barry's slightly higher pitched voice.

"Really? What, do you also age at super speed? Because if that's true, we only have to fight you for another five years, tops. Do you want to grab a beer and enjoy life or something? I'd be worried if I were you."

That was my chance. I rubbed the shoes together and super sped up to him, trying to grab his gun. He darted away fast enough and shot at me with a cold beam, the air around it becoming cold. He would've shot me if I wasn't moving so fast.

His comrades also started shooting at myself and Ronnie, beams of orange and gold everywhere. Ronnie flew into the air and started shooting off fireballs at the criminals. I stood and faced down Captain Cold.

"Seriously!" he yelled, aiming his cold gun at me. "You have a max of five or six years left, you should be out there YOLO-ing right now or something!"

"Guys!" I whispered into my earpiece, remembering Caitlyn and the weird kid on the other end. "What do I do?"

"Well, if Barry taught us anything, it's that you shouldn't try to run around and let them shoot at you." The weird kid said, and chewed on something that sounded like a potato chip.

"Try to smash their guns or something." Caitlyn shrugged.

I heeded their advice. I super sped up to Snart and reached for his cold gun, but he pulled it away and nearly shot me in the back. I had to try again. But this time, when I sparked up my shoes, there were only a few sparks. My hour with super speed was almost up.

This one had to count. Without my bow and arrow or super speed, I couldn't fight Snart with his gun. I ran up as fast as I could and reached out for the cold gun. I felt the air become colder and colder, Snart coming closer. Finally, I felt the gun, and grabbed it as hard as I could, yanking it out of Snart's hands.

He stood there, shocked, as I threw it across the room where it hit a wall, shattering into pieces. That was it. I took off Barry's red gloves and beat the crap out of Captain Cold. When I was done, I dragged his unconscious body over to Ronnie, who had tied up the other two and used his transmutation powers to turn their guns into Barbie dolls.

Police cars came by to drag the criminals back to prison, where hopefully they would stay. Ronnie nodded at me for a job well done, and I disappeared into the night, even though it was five in the afternoon. Fighting crime in sunlight disgusted me.

Leave your requests for who should become who for the day! You can pretty much use anyone, and leave a name so I can credit you if I use your idea!
