I looked up the reviews, not too bad, nothing about Unison Sonic being pink so I'm kind of surprised. Anyways if no one noticed I added 2 more male characters in the Poll, this is because I'm bringing in Shadow and Knux.

Sonic Adventure Lyrical Step

Chapter 4

Mysterious Floating Island appears! Reds and Projects Clash! What the?

-TSAB HQ, Mid Childa. 3:00 PM-
*Insert: "Welcome to Station Square" Sonic Adventure*

After spending a few hours learning the basic shield spells from Nanoha, Sonic was accompanied by Nanoha and Hayate to speak with Admiral Chrono and Carim from the Saint Church

Chrono, after reading a floating screen, turned to the hedgehog "The results of the mock battle came in. You're being classified as AAA Rank in your normal form, while both your Super and Unison forms have been classified as S rank."

Sonic asked curiously "Rank? What does that mean?"

Nanoha explained "It's how the Bureau keeps track of how powerful individuals are, they are ranked by letter grade. Having an "A" rank alone marks you as one of the top level mages in comparison to run of the mill recruits. You go from A to AA to AAA and finally the S ranks. S and SS. My power is ranked as "S+" same as Fate, while Hayate has a "SS" rank because of her Linker core merging with the Book of Darkness"

Shahra asked "Linker Core?"

Hayate explained "An organ in a mage or knight's body used for mana for spells. Often one's core is tested by its capacity"

Carim gathered attention "Now that we all understand each other, Sonic?"

"What?"

"You said you were teleported here by a portal? Nanoha and Hayate both are from non-administrated world #97 or "earth" and it'll take some time but we could get you back to your world to stop this Eggman you were speaking of"

Sonic smiled and shook his head "Nah, I'll pass, I'm always up for adventures in a new world, and if I know my friends odds are Eggman's already been stopped by my best bud Tails, he's grown so much, I saw him as a little brother I never had, I'm confident in him. Speaking of him, I bet he'd be really excited at seeing this, he's a genius at technology and inventing, and he's still a kid too."

"Could you tell us more about your friends Sonic?" Chrono asked

Before Sonic could say anything, they all felt a rumble and Fate entered in a hurry and out of breath

"Everyone…. Come with me please, something big is happening at the lake! A huge distortion in time and space.. Something big is coming out!"

Everyone nodded and rushed out to the lake while meeting Vita and Signum. There they were met by a gigantic island floating in the sky.

Sonic whistled "Angel Island. Now what's it doing here?"

Fate asked "You know about it?"

Sonic nodded "Yeah, I'd explain but some things are better left seen for yourself, to get up there we've got to fly. So Shahra?" and rubbed his ring, changing into his Knight Clothing.

Shahra "Yes Sonic?"

"We need that magic carpet, we have an island to visit." And with that Sonic leapt onto the carpet. Nanoha, Fate, Hayate, Vita, Signum and Chrono all changed into their barrier jackets and knight clothing respectively (a simple combat uniform and overcoat for Chrono), while Carim rode the carpet towards the floating island.

-Angel Island-
*Insert: "Unknown from ME" Sonic Adventure 2*

When the group arrived at the Island, everyone except for Sonic was amazed by the sight of the ruins they saw. The ruins were that of an old shrine, in the middle were staircases leading up to an Altar, where a large green emerald rotated in place.

"What is that? It looks like one of those emeralds Sonic has, only larger." Carim observed

"The Master Emerald, this relic serves to keep the powers of the Chaos Emeralds in check. When I transformed into Super Sonic, I must have accidentally used Chaos Control to bring it here, along with Angel Island." Sonic thought out loud, then cautioned the group "Don't step any closer! Its guarded" But his plea fell on deaf ears when the group approached the steps, only to stop when they saw 2 figures standing guard.

The first was a red short-nosed echidna with dreadlocks flowing down his head, violet eyes, a white crescent moon shaped birthmark on his chest, wearing red and yellow shoes with metal plates and green socks and white mittens on his hands that have 2 indents poking out, emphasizing the knuckles. This figure was sitting and eying the approaching group with a serious expression. The other figure was a black hedgehog with a tuft of white fur on his chest, eyes the same color as Fate's red, four of his quills are bent upwards (outer ones) the other 2 bent downward like Sonic's. This black hedgehog was wearing black, white and red shoes with jets coming from the bottom along with black and red socks cuffed at the ankle, and white gloves with matching black and red cuffs; on top of these cuffs are 4 gold rings fitting on the wrists and ankles. This figure watched the group with a stoic expression.

The red echidna took another look at the group, then after noticing Sonic, ran straight up to him with a fanged smirk and high-fived the blue blur "Hey Sonic! Long time no see! Nice outfit"

Sonic smirked equally "Hey Knuckles. Shadow, whats up?"

Knuckles replied "Well everything was normal until Shadow showed up asking where you were, you had the Chaos Emeralds last he heard and he lost track of them. And to top it all off the Master Emerald glowed and Angel Island rumbled, we woke up and here we are catching sight of those guys. You wouldn't happen to know anything about that would ya?"

The black hedgehog now identified as Shadow stormed up to Sonic completely ignoring the Bureau members watching the conversation "Speak up, Sonic! How did this happen?"

Sonic waved his arms defensively "Take it easy there I'll explain. What happened to Eggman? He threw me into a portal that took me to the world we're on now, and yes I have the Emeralds with me, Angel Island must have been brought here by them when I transformed into Super Sonic earlier."

Shadow informed "He was dealt with, after you destroyed the attack fleet, Tails, Amy and I followed up. The doctor was informative enough to say that you were only teleported into this dimension."

Chrono chose this moment to interrupt "Sorry to interrupt your catching up, but who are these 2?"

"I'm Shadow, Shadow the Hedgehog, The Ultimate Life-Form"

"Knuckles the Echidna, just call me Knuckles. I guard the Master Emerald"

After everyone was introduced, Vita approached the Master Emerald "This is the "Master Emerald" that's supposed to control the Chaos Emeralds? It doesn't look like much"

Knuckles glared at the eternal child "Watch your mouth, kid, the Master Emerald is an age old relic of my clan."

Vita returned the glare "Who are you calling a kid? You're making me mad, let's go Graf Eisen" and wielded her device in its small mallet form.

Knuckles smirked his fanged teeth in cockiness and pounded his fists together "Bring it on!"

- Knuckles VS Vita-
*Insert: "Suitable Opponent" Sonic Adventure 2*

Knuckles started off the fight by performing a horizontal spiral fist attack aiming straight for Vita; who avoided this and countered by slamming him with her mallet. The Echidna didn't let up, he clenched his fists and gathered energy into an expanding red aura, which he released into a powerful blitzing charge (Maximum Heat Knuckles Attack) at Vita, and this one grazed her, but also in the process knocked off her hat.

Vita took notice of this and really got mad. "Graf Eisen!" She shouted, her device spoke in german "Schwalbefliegen"(Flying Swallow) and after generating 4 iron bolts floating in mid-air she sent them towards the echidna. Knuckles smirked at this and drilled underground to avoid them, he came out from the ground in a surprise attack delivering an uppercut while Vita was off guard. Vita then called for her device again and its response "Raketenform" (Missle Form), and the head morphed into a rocket. Using this new form and the "Raketenhammer"(Rocket Hammer) she spun and hurled herself at Knuckles, only to be frustrated as Knuckles burrowed underground again. For 5 minutes the whole battle was nothing but Knuckles taunting Vita then digging before she hits him.

Both combatants were held in place, Vita by Hayate and Knuckles by Sonic when he exited the ground. Sonic remarked "Oi.. Enough of that, as much as its funny to see a game of "Whack-a-Echidna" 5 minutes straight kind of makes it dull." After this both combatants were calmed down to the occasional glare. The group left Angel Island after Sonic's story was fully explained.

-TSAB Training area-

Everyone paid a visit to the training area. Shadow and Fate couldn't help but stick close, both feeling a sense of familiarity from each other.

Fate asked rather nervously "Shadow, was it?"

Shadow raised a stoic eyebrow "Yes?"

"Would you mind having a mock battle with me? Theres this sense of familiarity I felt from you, maybe if we fight each other, displaying our abilities we could figure out why"

Shadow grunted but nonetheless agreed "This feeling is shared. Let's try this idea."

With that the stage was set up, Fate was now in her Barrier Jacked Impulse wielding Bardiche in Device form, while Shadow just stood there calmly ready for battle.

Nanoha announced "Ready Go!"

-Shadow VS Fate-
*Insert: "For True Story" Sonic Generations mix*

Shadow first started off by skating with his airshoes charging into Fate with a straight kick, to which she blocked with Bardiche and knocked Shadow back. Shadow then through use of "Chaos Control!" teleported right back to Fate delivering another kick, this one blocked with her arm. The combatants continued to trade blows while also matching each other in speed, Shadow intercepting Fate with his own Spin-dash, while Fate intercepting Shadow with Bardiche. Both fighters backed off to give some distance for this next clash.

"Plasma Lancer!" Bardiche calls out; Fate created several arrowhead-shaped bolts and flung them at Shadow. Shadow's response to match was his ability "Chaos Spear!" which he created and sent spear shaped bolts effectively cancelling out each other.

Fate comments "Your abilities are similar to mine. When we clash, I feel like I'm clashing with someone like myself. Are you artificial, like me?"

Shadow nods folding his arms "Yes, I was created by Professor Gerald, the grandfather of Doctor Eggman, as part of "Project Shadow" a project for the Ultimate Life, but the Professor's true intentions were to save his granddaughter Maria who was dying of a terminal illness."

Fate looked surprised and relaxed her grip and released Bardiche "Project Fate, that's what I was created from. The one who created me did so that I could act as a clone for her daughter, who died in an accident at only 5 years old. I guess you and I have a lot more in common than just our eyes."

Shadow could only nod "It looks like it, I don't know why we have theses similarities, but I can be sure of this, I put my past behind me"

Fate nodded "Same here, I've come to terms with myself and put my own dark past behind me" she held out her right hand "How about we turn our similarities into a friendship?"

Shadow, in a rare moment, smiled and accepted Fate's hand "Yes, friends." The 2 shook hands.

After watching this all, Sonic turned to Nanoha "This is one of the few times I've seen Shadow smile, he usually hides his emotions with that expression."

Nanoha added "Fate-chan didn't like being an artificial mage. Even though she's come to terms with herself, she still has her reservations, seeing a kindred spirit like Shadow must have allowed her to feel not as ashamed of her status."

With this everyone returned to the Headquarters after Carim returned to the Saint Church and Chrono taking his leave as well.

After a nice meal the group said good bye to Knuckles, who opted to return to Angel Island to sleep close to the Master Emerald. Shadow slept on the roof above the complex where Nanoha, Hayate, Fate and Sonic slept. Sonic opted to taking the couch and with that the day comes to a close.

-End Chapter-
Author's note: Okay, so I tried out something on this. Hoping it works out well to what I'm planning later on in the story I hope this part fits Fate's character. And I'm also taking a gamble hoping that Mid-Childa actually has a lake nearby on one note. As of right now, Shadow, Knuckles and Sonic are the only Sonic characters I'm planning on for this, if anyone would like to see another Game canon Sonic character feel free to request it in a review and I'll see about fitting them into the story. The poll is still up and I'll keep it up until more results come in, it's on my profile.
