Shadow the hedgehog Tfp crossover.

I own nothing.

Two motorbikes drove side by side. One was a Harley 2007 model and painted black. It's rider was Shadow the hedgehog, a genetically engineered mobian crossed with the DNA of a species called the Black Arms. The other motorbike was blue with pink highlights and of an unknown make, this was Arcee, a cybertronian autobots. Riding with her was her partner Jack Darby, a human, black arms hybrid simular to shadow who was made three months after him, one day before the death of Maria. Currently they were driving through westopolis towards a meteor strike. The meteor was once a part of the black comet from seven years ago and the size of it was easily large enough for a black arms giant to hide in it. Arcee was in the dark on this mission, she was told jack was to work with shadow on an investigation assignment and she wanted to come to keep him safe to which fowler allowed after a nod from shadow. Ahead was a roadblock set up by G.U.N the Guardian unit of nations. In the middle of the intersection was a deep smoldering pit forty meters across and thirty deep with a large smoking rock in the middle. Armed men in grey GUN uniform held rifles and rockets at the ready.

"Hmm, somethings not right." shadow muttered as he stopped and got off the bike as Jack climbed off Arcee and she transformed.

"Yeah, this wasn't a normal strike, this was guided and shot here." Arcee agreed.

"Sirs, ma'am good to see we got two ALs here and a bot." the CO grinned as he slung his rifle over his shoulder.

"ALs? " Arcee asked in confusion.

" None of your business Cee." jack snapped sternly. The femme was taken back slightly. Jack rarely lost his cool.

"Somethings moving! " one of the soldiers shouted as the sound of rifles being cocked field the air. Arcee primed her blasters and walked over to the crater with Jack and shadow. There was a Crack and a green gas exploded from the rock.

" Toxins! " one soldier coffed as everyone hurrily put of gas masks. Two of them weren't quick enough and fell over paralyzed.

" Ahh, Earth." a deep rasping voice sighed. Shadow's eye twitched and Jack got in a fighting stance. "CHAOS BURST!" from within the meteor a red burst of energy burst out, sending cars, barricades, soldiers and equipment flying. Arcee staggered slightly while jack and shadow stood there like it was nothing. "How fitting, my children are here to greet me." the voice snarled from the now smoke filled crater. Only three glowing red eyes were visible.

"It can't be." shadow gasped.

"how'd he survive? "jack growled. From the smoke hundreds of black creatures that resembled starfish with wings flew out of the crater.

" Black arms? "Arcee asked in awe. She'd read up on earth's past relations with alien species. The two on record were the mobians, who for the most part were peaceful, the other group was the black arms, a group of aliens who attacked and nearly destroyed earth easily and was only stopped by Shadow and an unknown person who used chaos abilities.

Next out were the black soldiers, reptilian humanoids with no mouths, orange insectoid eyes and red markings who stood around eight foot tall. They didn't attack but stood at the ready with guns primed. Then the smoke cleared showing a three eyed creature with three digit hands and looked like a floating torso.

"Doom devil." Shadow snarled.

"Shadow. Jackson." the alien grunted. "join us or die."

"CHAOS SPEAR!" both jack and shadow shouted as a red and a Crimson Spears were fired off. They struck doom devil in his arm and his left side.

"Destroy them! "the injured alien shouted as he vanished in a blue burst. The aliens charged while shooting. Arcee opened fire upon the aliens. Jack hit one with an uppercut, launching it into the air before teleporting above it with a blue flash and scissor kicking it towards the ground and he vanished with another burst of blue and appeared just before the alien hit the ground and punched it in the chest, sending it flying into another alien, killing both with the force of the impact and leaving a crater in the road. He ducked under another punch and kicked the alien in its jaw as he flipped back and twisted the wrist of another alien and yanking the ray gun free before flashing away to thirty stories above the ongoing battle as he rained down shots upon the aliens as he fell. By the time he hit the ground, he'd taken out eighty aliens and upon hitting the ground he let out a powerful chaos burst, incineration the aliens, some blockades and a few black Hawks which were flying around.

Shadow punched an alien into a wall, killing it before flashing just above an alien and spiking its head with both fists, crushing the skull before he flashed sway again and preformed a roundhouse kick on the next alien, sending it flying and flashed again and caught it by its ankle. He then swung the alien, knocking over two more just as he saw jack come down from the sky shooting like crazy. He spin dashed two more before jumping up and using chaos burst the same time jack did. The combined force of two ultimate lifeforms using chaos burst shattered every window for hundreds of miles, incinerated half the offending alien army and sent cars flying. Arcee was flung into a wall and was knocked out on impact.

"I haven't had a fight like that since Tuesday." shadow chuckled under his breath as he walked over to jack.

"Still got it." jack smiled slightly as he rolled his left shoulder,making it pop. "Ugh, this stinks, black arms are back."

"technically with us around they were never gone." shadow said with a roll of his red eyes.

"Yeah Yeah, don't remind me. Hey, where's Arcee? "jack asked in concern.

" That answer your question? "shadow asked as he stuck his thumb in the direction of the ruined lobby where Arcee laid.
