A/N: Alright! Here is part 1 with the fight against JS! And his identity will be revealed in part 2!

Chapter 11: The Mysterious JS

(Station Square Hotel: 5:30 P.M.)

It was raining today, Cream was sighing, Cheese and G-Mel were with her. There's isn't anything to do right now. "What should we do today?" Cream asked Cheese. "Chao! Chao!" Cheese said they should play some board games. "I agree with Cheese." G-Mel agreed. "Alright, let's play some board games." Cream said happily.

As she and her friends walked out of the room, they saw Shion staring at the window sadly. "Hey, what's wrong Shion?" Cream asked as she, Cheese and G-Mel walked up to Shion.

"Oh. Cream. It just... today is the day of the final battle with the Gnosis in my timeline; it's like a anniversary, but a sad one. My older brother, Jin sacrificed his life to save our timeline. I missed him ever since that day." Shion said sadly, Cream and Cheese looked at the ground in sadness too. "We're sorry for your loss." Cream said, Shion smiled weakly. "It's ok, I got over it... Huh?!" Shion, Cream, Cheese and G-Mel looked at the window after lightning hit, they saw a figure on one of the buildings, they got a closer look, it was Nazo's third in command, JS.

"That's Nazo's third in command!" Shion gasped, lightning hit again and when it cleared, JS was gone. "We better tell Sonic!" Cream shouted as she, Shion, Cheese and G-Mel went to tell Sonic.

(2 hours later)

Sonic and the crew head to the entrance to Speed Highway. Shion told everyone about Nazo's third in command, Trista sensed he is in Speed Highway.

"There's no doubt. He's in Speed Highway, somewhere." Trista told everyone. "Let's take care of this JS guy so we can resume hunting for the Chaos Emeralds." Inuyasha said gruffly. Everyone entered Speed Highway.

Inside, the visitors to Sonic's world were amazed to see a busy highway. "No wonder they called it Speed Highway!" Lina gasped in awe. "We better split up to cover more ground." Sonic told everyone. The group split up into 5 groups to find the mysterious JS.

Lina and her group were chased by busy cars when they tried to enter the tunnel which is a car tunnel. Inuyasha and his gang battled Shell Lizards while investigating the alleys. Laharl's crew was having trouble with Flying Lizards, but they defeated them and Etna managed to hold back Laharl from destroying Speed Highway.

Himeno's group, Astro and the Negima crew fight some Fighter Lizards while seeing the sights.

Tails fly high and low for JS, Knuckles climb some walls to search for JS. Shadow and Silver were on top of the buildings to get a better view to find JS. While the rest of the group did some things to find him, but no luck.

Sonic, Zoey and Shion were walking down the streets. "No sign of him. He must be pretty crafty." Zoey sighed. "Yeah. Nazo may have a pretty powerful minion." Sonic agreed. Suddenly, Shion stopped and looked up. "Shion? What's wrong?" Sonic asked, Shion pointed to the building, Sonic and Zoey looked up and gasped, it was JS!

JS leaped from the building and landed on the ground. He stared at the heroes and muttered one word. "Fight..." JS unsheathed his katana and points it at the three. 'Wait... Where did I see that katana before?' Shion thought to herself. "Alright, if it's a fight you want..." Zoey got into a battle stance when she started. "It's a fight you'll get!" Sonic speed up to JS.

JS: Part 1: Supporting me from Sonic Adventure 2

JS warped out of the way. "Huh? Where did he go?" Sonic looked around, JS appeared and was about to slash Sonic, but Sonic dodged it and hit JS with a Homing Dash. JS jumped high into the air and launched 2 dark blades at Zoey, she dodged them with her cat like abilities.

"Sonic Wind!" Sonic fired a Sonic Wind at JS who blocked it while Zoey gave him a kick. JS struck the ground with his katana and made a earth pillar and hurl it at Sonic and Zoey who dodged it.

"Wind Arrow" Sonic fired a Wind Arrow at JS who didn't blocked it this time and was hurt a little. Zoey ran up to JS and give him a kick in the stomach.

"Weak..." JS muttered as he launched 3 dark slashes at Zoey and Sonic who dodged them as always. Sonic gave JS a Homing Dash three times.

"Resistance is futile..." JS muttered again as he started to charge up to launch his most powerful attack, suddenly, Shion knows who JS really is. A flashback of Jin during her time in her timeline occurred.

"Jin! Please stop! It's me, Shion!" Shion called out to JS. "Huh?!" Sonic and Zoey gasped and turned to Shion with a confused look. JS stopped charging and stared at Shion for 35 seconds. Then he muttered "Shi...on...?" JS suddenly felt pain in his head and holds it as he screams in agony, suddenly, lightning hit and JS was gone.

"Hey! What happen?!" Vector yelled as he and the others walked up to Sonic, Shion and Zoey.

"We encountered JS, but he escaped for some odd reason." Zoey stated. Sonic turned to Shion.

"Shion... you know who JS really is?" Sonic asked, Shion turned to Sonic and nodded.

"Yes... JS... Is really... my brother, Jin..." Shion said grimly, everyone gasped in shock.

"I... Don't believe it..." Cream gasped in shock.

JS is really Jin... But how will Sonic and the crew free him from Nazo's control?
