A/N: Welp, just to clarify, this story is a spin-off/movie/whatever of my other story, "Sonic: Evil Reborn Zero." I figured that I'm aping Dragon Ball Z so much in that story, propping Sonic characters up with DBZ-esque powers, that I might as well do a crossover proper. SERZ Sonic with Saiyan Saga DBZ. Meteor Flurry! takes place between Episodes 21 and 22 of SERZ. Of course, think of it in a Dragon Ball Z manner: it wouldn't actually fit if you tried to place it in canon.

Enjoy!

"Hmm? Hold on, there is definitely something heading in this direction. And it's not just one- I'm picking up several more power levels," Vegeta suddenly says, turning off into the opposite direction. This causes everyone to gasp, with snaps of shock ripping through the beaten Z-Fighters.

"Huh?" Nappa then turns all the way around as well. "So you're telling me these rats have more friends on the way?"

Vegeta scowls, then smirks as his red scouter fully analyzes all of the signals. He kicks up a small rock and begins tossing and catching it with his left hand. "Nothing to worry about." With a bit of a cocky laugh, he goes on to say, "Most of them aren't even topping five hundred. Only one is at their level, and it's only fifteen hundred."

Nappa howls with laughter. "You rejects! If that's the most you can bring, that alone should be reason enough to kill you all!" he adds on with brutal sadism.

Piccolo, however, turns to Krillin with a puzzled man's look. "Wait a minute, but who else..."

Krillin replies, "Huh, I guess more people were training to fight the Saiyans than we thought." Then he's overcome with dread. "You don't think..." he begins, shuttering at the thought. "You don't think that's G-Goku, d-do you?"

"Urgg..." Piccolo growls. "Fifteen hundred... We'd better hope not. If Goku's been keeping us waiting this long only to come with such a pitiful power level..." If Namekian could turn any more green, the color would be overflowing off of him. He knows it's best to just keep it out of his mind. Goku... If that's really you, then please tell me you have a trick up your sleeve. If fifteen hundred is as weak as they claim it is, then you'd just be throwing your second chance at life away.

"W-well?" Gohan shivers. Even he understands, at this point, that a power level of 1,500 won't do them any more good than they already have. "Is it my daddy?"

Piccolo throws his head to side, grunting a bit before speaking his response. "It can only be him. There's no one else on the planet other than us that knew in advance that the Saiyans would be here. But that other one said that there were several power levels, so maybe he brought some special kind of help."

"Hahahahaha!" Vegeta cackles, still tossing and catching the stone. "You're so used to fighting on the terms of this miserable planet that your Namek mind just can't fully come to grasp our power." The stone hits the ground with a kick of dust. "Nappa, when these 'uninvited guests' show up," Vegeta crushes the rock with a swift jab of his boot. His next words are low toned full of malice. "Make sure they never touch the ground in one piece."

"Heh heh! I like the sound'a that!" Nappa super accelerates towards Piccolo, his clenched hand capable of impaling the dark hero. Piccolo hadn't even fully registered Nappa's sentence, and he doesn't even have a great deal of time to dodge or block or even move. It all seems to be the end of the line for him when...

"Chaos... ConTROL!" Saliva and blood shoots out of Nappa's mouth as a red-on-black leg nearly shatters the top of his spinal cord. He lumbers forward, mere meters from Piccolo, giving the three remaining Z fighters enough time to zoom off into the air. Vegeta silently growls as he sees what is definitely a disturbing sight.

Shadow the Hedgehog, standing alongside a group of the legendary, if non-existent Sonic heroes, has entered the fight.

"What's this?" exclaims the Saiyan prince. He throws out his arm imperiously and screams with palpable rage at the nonsense he's witnessing. "Woodland beasts? Now we're fighting common woodland rodents? What kind of farce is this?" Piccolo, Gohan, and Krillin look on in a fusion of surprise, bewilderment, and sizable dismay. If Yamcha, Tien, or Ciaotzu were still alive, they would feel the exact same way.

"Uh, guys, just tell me point blank. Am I losing my mind or did I just see a hedgehog land the best blow to that monster all day?" Krillin shouts.

"So we're not too late..." Shadow mutters in his perpetual depressive low tone.

"It can talk!" Krillin adds on, voice waving in pure awe. Piccolo looks on, dumbfounded and barely able to fully comprehend what he's seeing.

"Nappa! I thought I said not to let them land!" Vegeta barks.

"S-s-sorry, Vegeta! They came in too fast for me!"

"Hmph. No matter. Just see to it that you skin these animals," Vegeta grimly replies, arms folded.

"Heh heh heh!" Nappa sadistically chuckles. "Guess what, ya litter' critters! Guess what good ole' Nappa's gonna do to ya! I'll mount you on my wall!" As soon as 'I'll' comes out of his mouth, Nappa super accels towards Shadow, easily pushing mach one.

Shadow raises his scarlet red, pulsating Chaos Emerald. "Chaos Control!" comes out of his mouth. The mystical gem obeys, and time splits from space, flowing slower than a microscopic snail. As Nappa's hammer of a fist comes down, he swats thin air, nearly breaking a hole in the atmosphere.

"Uh!" He looks up. Standing half of a mile away is the ebony on crimson hedgehog.

Vegeta looks on in astonishment, mouth agape. He could just barely follow Shadow's movements. It's as if he was moving at the speed of light, Vegeta thinks. What-what is this?

"Sonic," Shadow shouts from the distance. "Give me your light speed shoes' ability enhancer." The azure hedgehog replies. From his red sneakers, he detaches a special blue crystal. He lobs the upgrade to his rival. Shadow catches with militaristic movements.

Vegeta eyes those that have come with Shadow- Sonic the Hedgehog, Miles 'Tails' Prower, Knuckles the Echidna, Amy Rose, Blaze the Cat, and Rouge the Bat.

"Let me take a wild guess- those teddy bears over there are your friends?" The Saiyan prince can't believe he's really conversing with a hedgehog, nor does he believe it replies. Arms folded, Shadow remains unmoved.

"You call them teddy bears as if they're only good for looking cute, but the truth is we've dealt with beings fifty times stronger than you before..." Shadow's eyes fly open as he snickers once, "and won." Vegeta subtly growls under his breath, not appreciating this smack his taking one bit. Nappa is far less patient.

"You. The one with all the make up on your- your... whatever those things are on your head. What's your name?" Vegeta demands to know.

"My name is Shadow. Shadow the Hedgehog." Immortal words, as always.
