A/N: I do not own Kamen Rider Double.

As Kamen Rider Double:
Shoutarou speaking

Philip speaking

As Kamen Rider Mar:

First figure speaking

Mar made the first move and ran forward, jumped into the air and delivered a punch. Double was able to block the punch, but Mar used this opportunity to kick Double on the side, causing Double to lose balance.

"I expected more from the ones who destroyed Museum." Mar grabbed Double's neck and black smoke formed around Mar's right hand. "Looks like your countdown ends here."

Double struggled. "Philip, I hope you have an idea."

"I do." Double closed the Driver and switched the Cyclone Memory. He then opened it again. "HEAT! JOKER!" Double's right side turned red and his hand lit with fire. Double punched Mar's body, forcing him to let go.

Mar chuckled. "Now that's more like it. Time to make this a real show." Mar closed his Driver, removed his Smog Memory, pulled out another Memory and pressed it. "FROST!"

He inserted it and opened his Driver. "FROST! ACE!" Mar right side changed into an icy blue color.

"He has more Memories?" Philip was perplexed.

"No time to think, Philip." Fire surrounded Double's hand again and he tried to punch Mar. But Mar blocked the burning fist with his right hand. Double's hand soon started freezing. "What the hell!"

"My turn." Mar grabbed Double's arm and flipped him to the ground. He punched Double on the chest, which soon started to freeze as well. Double tried to stand up, but the hit froze his left side, leaving his left arm immobile.

"We need to switch." Double removed the Joker Memory and switched it with Trigger. "HEAT! TRIGGER!"

Double pulled out the Trigger Magnum and started shooting fire blasts at Mar. Mar dodged all the attacks while switching his Ace Memory with another Memory. "He pressed it. "BLADE!"

He then inserted the Memory and opened his Driver. "FROST! BLADE!" Mar's left side then turned into a crimson color. A sword also materialized on his back. He pulled it out and started slicing the fire blasts in half with his sword, now covered in ice.

"His Memories are able to counter ours." Double continued shooting, but to no avail. Mar jumped in the air and delivered a slash wave made of ice, freezing the Trigger Magnum.

"Let's try this then." Double removed Trigger and inserted the Metal Memory. He opened the Driver. "HEAT! METAL!"

Double's left side turned silver and he pulled out the Metal Shaft and it clashed with Mar's sword. They continued to clash their weapons, causing sparks of fire and shards of ice to scatter around.

Mar pulled out another Memory and pressed it. "ELASTIC!" He inserted it and opened his Driver. "FROST! ELASTIC!"

Mar's left side turned bronze and a whip covered in ice materialized. He used it to grab Double's Shaft. Ice quickly started forming around Double's weaponl.

"We have to end this fast." Double pulled out the Metal Memory and inserted it it into the Memory slot in the Metal Shaft. "METAL, MAXIMUM DRIVE!"

"Metal Branding!" Both ends of the Metal Shaft lit on fire and Double ran forward for the finisher.

"Looks like your about to bring your own end." Mar removed the Elastic Memory and inserted it in the Memory slot in the handle of his whip. "ELASTIC, MAXIMUM DRIVE!"

"Elastic Blizzard!" Mar twirled his whip, facing Double, forming ice and snow around the whip. Mar then lashed his whip, releasing the accumulated ice and snow straight at Double.

Double quickly delivered his attack at the incoming blizzard to cancel Mar's attack, but the blizzard was so strong, Double was pushed back and his hands froze from the attack. Mar then used his whip and wrapped it around Double, freezing his upper body.

"Well, looks like that's all the 'great' Hidari Shoutarou has to give." Mar removed both Memories and turned back into SmogAce. "Time to end both your lives." He inserted the Ace into the Memory Slot on his right. "ACE, MAXIMUM DRIVE!"

"Ace Toxin!" Black smoke surrounded Mar, lifting him into the air. His body then splits in the middle and he delivers a kick right at Double. Double was knocked to the ground and the transformation was canceled.

Philip got up and saw a wounded Shoutarou lying on the ground. "Shoutarou!"

Shoutarou slowly got up. "I'm fine. Just a little bruised."

Mar closed his Driver and transformed back. "I'm surprised you're still alive," the first figure said. He then faces the second figure, who just got up. "Go. You know what to do." The second figure nodded and ran off.

"Hey! Get back here!" Akiko yelled.

"I wouldn't bother following," the figure said. "In fact," he then pulled out a handgun and pointed it at Shoutarou. "I would be more concerned about his life."

"Who are you and what do you want?" Shoutarou asked, not scared by the gun being pointed at him.

"Very well. I guess I should at least show you the last face you'll ever see." The figure placed his hand on his mask and slowly removed it. When his mask was removed he looked right at Shoutarou. He was a young man with black hair. He had a long scar on his left cheek similar to the one on his mask. He gave Shoutarou a devilish grin. "Well, Shoutarou, it has been a while."

Shoutarou had a shocked expression. "It can't be."

"So, do you still remember me?" the figure said.

Shoutarou opened his mouth and said a name he thought he never would say again. "Adauchi...Shou."
