Shadow

"I found you… faker." Said a familiar voice from behind Sonic.

And Sonic couldn't help but smile.

"Faker? I think you're…"

"Ok no, we are not doing this." Shadow said as he sat down beside Sonic.

"Oh what?! Then what was the point of you popping in and saying that?" Sonic asked.

"I was simply stating facts."

"Oh…" Sonic said, feeling a bit silly. "So, how'd you know to find me here?"

"Rouge found out that you were back from Knuckles, and told me to investigate." Shadow explained.

"Oh what?! He couldn't keep it a secret for a day?!" Sonic groaned out.

"More like she took his communicator and saw a picture of you that Tails sent." Shadow clarified.

"Oh… wonder when Tails did that…"

"When you were freaking out about Skye." Shadow answered.

"Oh…"

"Sonic?" Said a new voice. Sonic then looked over to see Tails flying onto the roof. "Who are yo- oh! Hey Shadow!"

"Good evening Tails." Shadow greeted. "Hate to do this, but I am going to need to borrow Sonic for a while."

"Yeah, figured that was what you were here for." Tails said.

"Alright, if you want to hang so bad, let's go Shadow." Sonic said before getting up.

"Hmph. Chaos Control!" Shadow said before the two hedgehogs disappeared in a flash of light.

"Welp, there he goes… better get back to bed." Tails said with a yawn before going back into the house.

On his way to bed though, he noticed something. His main computer was still on.

"That's weird, I could of sworn I turned this off…" Tails said before turning off the computer. "Oh well, it's probably not important."

If only he knew exactly how important it was.

When Sonic and Shadow reappeared, Sonic took a good look around.

"Tails' testing grounds?" Sonic asked. "What are we doing here?"

"Simple, I need to see if you are the real Sonic or not." Shadow said.

Sonic just sighed. "Really? And how do you-" Sonic started before swiftly dodging a punch. "Oh, so that's how. Been a while since we duked it out, huh?"

"You could say that… over fifteen years." Shadow said.

"Yeah, can't wait to see how much you improved." Sonic said. "Try not to kill me, ok?"

"If I end up killing you, that would mean that you are a fake." Shadow quipped back.

"Oh ho! Now you're talking!" Sonic said.

And with that, the battle was on…

aaaaand it's done.

Turns out, Shadow became a lot stronger over the years, and was more than capable of completely thrashing the still teenage Sonic using Chaos Control and Chaos Spear rather viciously.

"I thought you said you were going to hold back!" Sonic said, after being completely pummeled by the Ultimate life form.

"I never said that, I just said that killing you would mean that you were a fake." Shadow said. "You passed by the way."

"Geez, I am so thrilled…" Sonic said sarcastically. "Seriously, I thought the Emeralds disappeared with me, how are you…?"

"I cut a deal with Knuckles. I can use the Master Emerald to recharge my energy, and in return I offer my full support whenever he needs help to protect the Emerald." Shadow said. "I wasn't exactly happy about it, but I had little choice."

"Geez, I knew you would be stronger, but that was ridiculous!" Sonic said.

"Well, you didn't improve at all." Shadow said with a smirk.

"Hey! I didn't have fifteen years to improve!" Sonic shouted.

"That's true, Tails could probably kick your butt now." Shadow said.

"You know, I wanted to ask about that." Sonic said. "What's up with you calling Tails… well, Tails?"

"What do you mean?"

"Well, fifteen years ago, you only called him things like 'runt' or 'brat'. What changed?" Sonic said, and Shadow just glared at him. "What?"

"Come on, let's go." Shadow said.

"So you're not going to answer my question?"

"Don't need to." Shadow said.

"Why don't you want to?" Sonic asked.

"Cause he doesn't want to admit that Tails kicked his butt once."

Sonic and a frustrated Shadow looked over to the source of the voice to see Rouge standing there.

"Hey big blue, good to see you again!" Rouge said with a wave.

"Rouge! Good to see you! Congrats on the engagement by the way." Sonic said.

"Oh, Knuckles told you already did he?" Rouge asked.

"Yeah, even invited me to the wedding." Sonic said. "Assuming I am still in this time of course."

"We will have to see." Rouge said.

"So, what's this about Tails kicking your butt?" Sonic said, playfully elbowing Shadow.

"Hmph, he simply caught me off guard when I hadn't recharged in a while." Shadow said.

"He's been using that excuse ever since." Rouge said. "It was quite the sight too, watching Tails fight like that."

She then got close to Sonic and started whispering. "Truth be told, the fight happened because Shadow was dissing you, but he did it to try and get Tails to man up and fight him, and gain some confidence."

Sonic just smiled. "Man, the more I hear about what Tails has been up to all this time, the more proud I feel!"

"He's not the only one who will make you feel that way." Rouge said.

"Oh really?" Sonic said. "Can't wait to find out who you are talking about!"

"What? You don't want me to tell you?" Rouge said.

"I would like for it to be a surprise." Sonic said.

Rouge just shrugged. "Very well then. Anyways, you should probably take him to headquarters." Rouge said to Shadow.

"I was just about to do that when you interrupted." Shadow groaned out.

"Alright, then get going." Rouge said. "Talk later big blue?"

"Of course! We still need to catch up!" Sonic said.

"Looking forward to it." Rouge said before Sonic and Shadow disappeared into another flash of light.

G.U.N. HQ

When Sonic and Shadow reappeared, Sonic got a look around, and saw that there was no-one around.

"Where is everyone?" Sonic asked.

"Asleep… it's past midnight." Shadow said.

"Oh, so then, what are we doing then?" Sonic asked.

"Most soldiers are asleep, but not all. The one that I am reporting to just so happens to still be awake." Shadow said before leading Sonic out of the room.

"O….kay?" Sonic said.

The two then began walking through the halls. They passed by a couple of soldiers, all of which began staring at the hero.

"Guess they're surprised to see me…?" Sonic said.

"Trust me, she will be the most surprised." Shadow said.

"She?" Sonic said.

"The one we are about to see, she is just through the doors." Shadow said as he stopped.

"Ok…?"

When the two of them went into the door, Sonic could not believe what he was seeing.

"Agent Rose, I think I found something that you would want to see." Shadow said.

"This better be important Shadow, and I told you, just call me A-" Amy said as she turned around.

And as her eyes locked with Sonic's, she dropped her clipboard.

End of Chapter 5

Just going to say this now, in this story, Amy looks pretty much like she did in Sonic Boom. Just feels like a more mature look for her, and I think it works for this.

ALSO, SUDDENLY AMY! Yeah, she's a part of G.U.N. now! How did that happen? That is what the next Subchapter is about actually. Not going to go straight into that though, I want to do the Amy chapter first, which is next by the way.

Can you guys tell that Tails is my favorite character yet? Cause I keep adding stuff to him… not intentional, I promise… maybe...

This is pretty much it for Tails though, he won't be back until the last couple of chapters, outside of a couple of subchapters.

Also the fight between Shadow and Tails will be a subchapter in the future, and I will actually write out that fight. So don't worry, it won't be over in a second like the fight in this chapter… sorry about that.

Anyways, see you next time for Amy!
