[Another day, another run through identical gunmetal-grey corridors. Business as usual for Sonic and Tails. The duo were picking their way through one of Eggman's smaller outposts, which reportedly was 'home' to the captive Sally and Amy. Sonic had been ordered to come alone if he wished to save them, so naturally, he brought Tails, with the rest of the team waiting outside.]
Tails: Let's see...signal lost...back again...left here Sonic.
Sonic: Got it, bud.
[Sonic veers left in the corridors, scraping a line in the metal.]
Sonic: Alright it's nice to be breezing through this, but where are all the 'bots? We trashed a few of them, but doesn't he have...you know, guards?
Tails: Make the most of it. I have the feeling it won't last.
Sonic: Good, I need the exercise.
Tails: I don't think overconfidence is the best policy here. With the immunity to roboticization dubious at best now, and the lack of guards, I've got a bad feeling that Eggman wants you to make it to him, so he can try and roboticize them in front of you.
Sonic: Nah. The Eggster's smarter than he acts, but he's as predictable as he is round. He'd probably do it in his main headquarters, broadcast it to the whole world, and then sic them both on us instead of demand that I come fight for them alone.
Tails: Then why haven't we heard the broadcast yet? Or why haven't we heard a call-in from one of the others about a broadcast? Think about every single time we've fought him. He doesn't waste time unless he wants to make a point to our face. I don't get what his game is, but he's got a card that we haven't seen yet.
Sonic: Think he's using them as bait?
Tails: As good a reason as any. Whatever he has in store, I can't see any of it. It was hard enough to lock onto Sally's genetic signature. You know the only way I got enough DNA for that was fur from you and her having fun on the sofa, right?
Tails: And I wouldn't know about that if you two didn't insist on waking me up with the noise every other night.
Tails: Alright, I'm done. Just be glad I didn't mention it when Amy's around. She's been bad enough since you gave Sally that ring. Couldn't do it on the quiet, could you?
Sonic: You know me, Tails. Even if I try to be low-key, I end up making a spectacle.
Tails: I feel like I should make a Loki joke with that but I have a distinct feeling it would fly over your head. You're not subtle enough.
Sonic: Well, got that right. Might need a crib-sheet for the sort of jokes you make, bud.
Tails: Thanks for the vote of confidence there.
[Tails grabs Sonic's hand, pulling him round a corner he was about to miss. The corridor ends abruplty ahead.]
Sonic: Nice save.
Tails: Thank you. It's pretty much a straight line from here., just stay on the main corridor, and you'll reach your target. I'll call Bunnie in, and we'll wait for your signal. Hopefully, you're right, and the lack of broadcast means that he isn't going to turn Sally and Amy into death machines. On the other hand... their Mecha forms would be, provided we have no other distractions, a walk in the proverbial park. If they're just bait for something worse...
Sonic: Then I have you and Bunnie for backup. We can do this, bud.
Tails: I hope you're right. And Sonic, no matter how easy it looks at first, if things go south, don't hesitate to call us in.
Sonic: I won't. See you on the other side, bro.
[Sonic bolts down the corridor, leaving a heavy tailwind in his wake.]
Tails: Let's just hope it doesn't come to that.
[The corridor ends sharply and opens into a massive chamber, a single walkway spanning the length.]
Sonic: Okay Robotnik, sensing the epic boss fight here...video games taught me that much.
???: Your naive instinct is correct, in this case.
Sonic: (glancing around) Do I know you and am I meant to care?
???: Of course.
[A figure drops down in front of him. It looks like a Metal Sonic, with a few differences. It is taller, and its torso is more than just an engine within a frame, not possessing an articulated midsection. Its limbs are slightly bulkier, and from its right forearm, a glowing blue energy blade extends. A small red light shines above the air intake, and the optics, which mirror the malevolent shine, look expressive and intelligent. It snaps its fingers, revealing Sally Acorn and Amy Rose, trapped within a polycarbonate cylinder. Neither woman seems even mildly unnerved, more annoyed at their capture.]
Metal Sonic: My name is Metallix the Metal Sonic, and I am your end.
Sonic: Well...At least he's trying to be inventive I guess.
[Metallix charges forward, the energy blade outstretched and humming darkly. The distance is closed quickly and Sonic rolls to the side, realising there is no floor to move to and ricocheting off the wall.]
Sonic: Give me more credit than that, or is your boss less inventive than I thought?
[His feet twist against the wall, a field of chaos energy holding him flush with the metal for a scant instant before he fires away from it, curling into a ball, spines erupting into their protective shell.]
[Metallix raises his bladed arm, digging his heels into the ground, and swats the incoming hedgehog aside with it. Fortunately, Sonic's diamond-hard quills protect him from the razor-edge, and he once again rebounds off a wall, looping around as he makes contact with the floor, before slamming into the android's back. He stumbles, glaring over his shoulder at Sonic.]
Sonic: But effective.
Metallix: You are the reason I was constructed. I am undamaged.
Sonic: Yeah, yeah. Whatever. Sal, Ames? You two doing fine?
Sally: (indignant) Please just deal with this guy. I'm embarrassed enough as it is.
Sonic: Gonna have to get over that, Amy.
[Sonic is cut off before he can say more, Metallix blurring past him leaving a glow of the blade over his vision. Then the blade is above him, slicing down and jarring sharply against a brief but vivid energy field.]
[Sonic dashes away before the barrier fades.]
Sonic: Ring shield. I keep forgetting I carry one of those.
Sally: Sonic, stay focused! If that happens again...
Sonic: Relax, I know what I'm doing.
[Sonic accelerates forward, pushing himself into his signature boost attack, before slamming into Metallix's front, and driving him into the wall. He keeps pushing, forcing his adversary further into the masonry, only to be caught off-guard when the robot fires his chest-mounted engine in reverse-thrust mode, unleashing a surprisingly large jet of flames. The flames light up around Sonic's shoes, the amazingly-heat-resistant material diverting the fire away as the hedgehog pushes back away from his foe once again.]
Sally: Know what you're doing. Right. Sure.
Sonic: I know what I'm doing!
[Sonic bursts into motion, hands lighting up. Twin bolts of light flash from him mid-motion, ripping through the air towards Metallix. The robot throws his blade up, the first bolt being cloven in two and the second one, poorly aimed, flying above his head.]
Metallix: Poor calculation.
Sonic: Oh, because you Egg-bots are so fantastic at marksmanship, right?
[Metallix withdraws his blade, and off-handedly fires a laser at Sonic's feet, blowing up the ground beneath him, and launching him into the air. He leaps up, and kicks the organic hedgehog back to ground, before stomping on his torso, and reactivating his blade, which is quickly joined by another one, extending from his left arm. He scissors the blades at his counterpart's throat.]
Metallix: I am no simple "Egg-bot."
Sonic: No, you're a simple Metal Sonic.
[Sonic disappears, flickering into existence behind Metallix once again.]
Sonic: You forgot the chaos powers.
Metallix: No. I did not.
Abilities analysed. Subroutines adapting.
Sally: That can't be good...
Amy: The last robot we met that could do that was...
Sonic: Beaten. By me. Twice.
[Metallix swings both blades at Sonic's midsection, but he jumps over the strike, aiming to come down behind his opponent. Metallix responds by pivoting half-way at the waist, and firing in reverse again. This time the blast launches Sonic off his feet and along the walkway, fur singed by the blast. He hits the ground running, turning on a dime and coming back into a spindash.]
Metallix: I am not my predecessors.
[The moment the two come together, Metallix slams one blade into the ground, the energy edge dying but the blade itself grinding against Sonic's spines.]
Metallix: Megatal. We learn.
[Pushing power into the strike, Metallix rips his blade free, taking Sonic with it like a baseball and hurling him away.]
Metallix: You are not invincible.
[Sonic makes a three-point landing, and lobs a Chaos Spear at the intake of Metallix's jet, only for it to fizzle out against a black energy field.]
Sonic: Never claimed to be, but the day I get taken out by the likes of you, another pathetic pretender, well, it's a long time coming.
Metallix: I am no pretender. I am Metallix. You never were.
Sonic:...well damn. The good news just keeps getting better and better! Botnik find time to give you a new personality in the middle of all his moustache stroking?
Metallix: That information is unavailable.
Sally: This isn't good... Sonic, you remember the last Metal that got given a personality?
Sonic: Yeah, the one with the starfish head, right?
Sally: I was thinking more along the lines of the part where it turned into a giant mechanical dragon than it's less that aerodynamic spines.
Metallix: He was ineffective. A failure.
[Almost in unison the two lock arms once again, blades grinding against a spindash.]
Metallix: The alloted time for playing is over.
Sonic: I was just going to say that. It's not that I don't like fighting your metallic mirror-images, but I promised Sal a nice dinner, the air'll be getting stale in that tube, plus Tails and Bunnie are gonna be going nuts with worry...
[Sonic jumps back, and spins in place for a few seconds, as a blue aura builds up around him. Metallix rolls his optics, but does the same, after which they both unleash the charged attack.]
Sonic: Let's go!
[The two hedgehogs charge into each other, and rebound away, doubling back, faster than Sally or Amy can register. Striking repeatedly, they rapidly become little more than a pale blue blur, appearing for less than a second, then vanishing again, until finally, they crash together, energies exploding in a blinding flash.]
Metallix: Objective complete.
Calculating next objective.
[As the glow fades from Amy and Sally's eyes, they can feel their fur patched with spots of blood from the blade puncturing Sonic's chest. The hedgehog stumbles and slides wetly from the weapon, an adrenalin-flooded system stopping his brain from catching up with the damage.]
[Metallix kicks Sonic in the head with the tip of his foot, knocking the hedgehog to the ground. His vision greys and darkens to nothing as his mind finally realises he is dead.]
