Well, I've been waiting to mix these together for a long time! Truthfully I made a crossover between the two heroes a long... long... LONG time ago, eh, might edit it and post it in the future. Anyway, this one's gonna be fun, I gained inspiration from "Mario and Sonic: Heroes Unite!", "Sonic & Megaman: Worlds Collide" and some parts for inspiration came from my first Sonic game Rush Adventure. During the chapter, Eggman uses a machine called the Egg Falcon, I am aware that Eggman used that machine's name in one of the Rivals games, but I don't take those into canon here.

Thus, it's time! I don't own Sonic the Hedgehog or Megaman. But I do own a new machine Eggman uses in this chapter, the Egg Falcon.

Spagonia

A blue blur zooms around, running on top of rooftops, and then with a "woosh" sound, the blue blur stops. He looks over to an egg-shaped hovermachine, seeing an egg-shaped person sitting in it, and then next to him is a sphere robot and a cube robot. "I'm in position." a small male voice says over a comlink, the hero, watching from a rooftop, but hidden replies. "So am I."

"So now what?" a gruff male voice asks. "We do what we usually do." a girl's voice tells the other one. That's when another voice cuts in. "Can we get on with this already?" the voice is more gruff and sounds like a guy you don't want to meet in a dark alley.

"Okay Shadow, yeesh! Knuckles, Amy and Tails, you all know what to do. Ready everyone?"

The others all reply "Ready!" and with that, a red echidna, Knuckles, glides down and strikes a few Egg Fighters with his spinning punch. "Heh, to easy!" he says, smugly. "Knuckles! Grr, Egg Launcher attack!" the bad guy yells out, as the Egg Launchers walk over, they have an "H" on their back, meaning they shoot horizontally. When they fire the missiles, they're intercepted by a pink hedgehog, Amy Rose, she uses her hammer and smacks the missiles right back at the Egg Launchers. "Eggman, you really need to come up with something new." she says smugly. "Spinners attack!"

The Spinners fly in, but luckily are all hit by a small yellow tornado, which is a yellow fox with two tails, Miles Prower, but goes by the name Tails. "Come on Eggman, what's next?" he asks. "Stupid... Egg Typhoons, Egg Flames ATTACK!" Then more robots walk over to the three. When Tails then secretly gives a signal, when a blue blur rushes over, along with a black blur. The Egg Typhoons and Egg Flames combine their attacks into a fire tornado, but then a voice yells out "Chaos Spear!" when the black blur jumps up, red blasts of energy fly right at the Egg Flames, and then the black blur lands on the ground, turning around, his arms folded he simply looks over at the person, the black blur is a jet black and crimson hedgehog, Shadow.

The blue blur rushes over, and destroys the attacking Egg Typhoons like nobodies business. He skids to stop, a blue hedgehog, known simply as Sonic! "Hey Eggman, how'd you get back to our world, last I checked you were stranded in the middle of nowhere." both the sphere robot and the cube robot roll over to the front of the EggMobile. "True that Sonic. Luckily we found one of the Chaos Emeralds and managed to get Eggman back here." Orbot says. "Yeah man." Cubot says with a Jamaican accent. Eggman then hits the both of them on their heads. "You idiots, I was gonna explain it. Ah whatever. You better listen good Sonic," Eggman adds, pressing a button, a Spinner, two Egg Pawns, and another Egg Fighter walk over, and they reveal a containment chamber with two captives, the container is cube shaped, with clear glass, near the top is holes for air to circulate, but there's a key keeping it locked. Inside it is a cream colored rabbit, a silver hedgehog, and a Neutral Chao are all in it. "Silver, Cream and Cheese." Sonic yells shocked. He then sees in Silver's left hand is the Silver Chaos Emerald, when Eggman opens the door to the hatch and takes the Emerald from Silver, who looks rather beaten up, so he doesn't put up much of a struggle to keep the Emerald. When all of a sudden a giant robotic falcon flies down and lands in front of them. "Ah yes, my new Egg Falcon. It's a shame it's first victims were your friends." Eggman says, when Sonic manages to get a look at Cream he sees one of the injuries is indeed talon markings. "What do you want Eggman?" Sonic demands to know. "How about a deal, the other Chaos Emeralds in exchange for your friends?" Eggman tells the heroes, as the EggMobile floats into the cockipt and he loads in the Silver Emerald and the Red Emerald. Tails simply tosses him the Yellow Emerald, the others gasp, but Sonic simply gives a nod to Tails. Amy walks over next, and gives up the Cyan Emerald, simply giving a worried glance over at Cream, she turns around and then yells "You are a terrible man Eggman!" next Knuckles walks over gives Eggman the Green Emerald.

The only two left are Sonic with the Blue Emerald and Shadow with the Purple Emerald. Shadow sighs and tells Sonic "This is the last time I go on a mission with you guys!" he tosses the Emerald over to Eggman, and he loads them in. Sonic then looks over at the injured Cream and the nearly unconscious Silver. Sonic then holds out the Emerald, Orbot rolls over and brings it to Eggman, both Orbot and Cubot going into the Egg Falcon. "Now Cream, Cheese and Silver!" Sonic yells, but the Egg Falcon simply does a talon swipe, and Sonic, pulling off some matrix moves is able to dodge. "Somehow I knew this was gonna happen." Shadow says. The Egg Falcon then gives off a glow, it gains a silver color, and begins flapping it's wings, it grabs one the containment unit with a talon, Sonic and Tails trying to get up high enough to stop it. However a machine attacks the two, forcing Tails to land Sonic on the top of a building. "Metal Sonic!" Amy yells out, knowing the form because Metal kidnapped her some years ago. "Metal's back again? Seriously Eggman, the Egg Falcon's the most creative thing you've done all day!" Sonic declares.

Metal prepares his V Maximum Overdrive attack, and when he uses it, Sonic dodges it, using some gymnastic flips. "Heh, looks like taking those gymnastics lessons wasn't a wast of time after all. If you want me, come and get me Metal!"

Not waiting a second, Metal Sonic flies over, trying to hit Sonic with the metallic claws for fingers, but Sonic does flip spins and is able to dodge all of the attacks. Eggman simply watches Sonic, kinda bored. "Eh man. Why are you watchin' the hedgehog, man?"

"Orbot change that voice chip! I hate that accent!" Eggman yells, Orbot then takes out the voice chip, fiddles with it, and puts it back in. "Hey, what's with Metal?" Cubot asks, now with a Russian accent. "Well it's better then the last one." Eggman mutters. He presses a button, and the Egg Falcon swoops down, catching Tails and Amy in one of it's talons, while it catches Shadow and Knuckles in the other one. "Sonic help!" Tails yells. Sonic turns around to see his friends, but when Eggman targets the main cannon at him, there's a discharge of Chaos Energy, and inside the Egg Falcon's cockpit a siren begins to wail. "What's that?" Cubot asks. "A warning alarm, shut down the cannon, the Chaos Emeralds are over-powering the system!" Eggman yells, as he tries to turn off the power and he accidentally presses the fire button, firing the laser right at Sonic and Metal.

It doesn't hit them and opens a portal, an explosion occurs, destroying the Egg Falcon, thus sending Eggman, Orbot and Cubot flying into the portal, all still on the EggMobile, along with a few Egg Fighters, but the portal also sucks up the containment unit, Amy, Knuckles and Shadow. Sonic, Metal and Tails barley still there. Soon Metal sees the Chaos Emeralds also sucked into the portal and jumps after them. "Help us... SONIC!" Tails yells, losing his grip on a fountain and also being sent into the portal. Sonic then jumps in and the portal closes, with the Chaos Energy now no longer flowing to sustain it.

Well that's the end of the first chapter, I hope you enjoyed it.

Don't forget to review.
