Equestrian madness

"That hedgehog will never catch up to me," Rainbow Dash declared to herself.

"Don't be so sure," said Sonic, catching up to her.

"What?! No way you can run that fast!" Rainbow Dash said in astonishment.

"What can I say? I'm a hedgehog full of surprises."

"You still can't keep up with my Sonic Rainboom." and Rainbow dash initiated the Sonic Rainboom.

"Hm" Sonic smirked and Boosted forwards, doubling his speed. He caught up to and passed Rainbow Dash at almost the speed of light.

"Wha--?" Rainbow Dash was shocked.

However, no sooner had that been said,  large boom sounded just on the other side of Ponyville, and the two racers stopped dead in their tracks. But before I tell you that, let's back up a bit.

"I'm going for the record," said a cyan hedgehog with red stripes at the base and tip of each spike. He looked just like Sonic in form, but not in color. His shoes were white and gray, with a lightning-shaped line down the middle separating the two colors, with white in the front and, well, gray in the back. He charged his figure 8 and took off at light speed, ripping the ground that he stepped on. Then space morphed around him. He became engulfed in light and disappeared.

A powerful wind came from the loud noise and almost knocked Sonic and Rainbow Dash off their feet. then clouds of dust appeared and when they faded, a cyan hedgehog with... okay, you already know how he looks.

"Did I just... travel through time and space?" the bright hedgehog wondered out loud. He appeared to be from the same world as Sonic. He looked slightly younger than Sonic, seeming about 13.

"Friend or foe?" Rainbow Dash would ask.

"I don't even know you people!" the hedgehog of an indeterminate name said. "Wait, are you Sonic the hedgehog?" He gestured at Sonic.

"Yes. How do you know that?"

"You're the most famous figure in Mobius history! But I thought you had been dead for several decades."

A look of confusion swept over Sonic's face. "What? But that would mean..."

"I'm from the future of our world." the cyan hedgehog finished.

They sat in silence for  few seconds, thinking about what had happened. Rainbow Dash shook out of her thinking mode. "Well, what's your name?" she asked.

"I'm Ike. Pleased to meet you!" the hedgehog who was apparently named Ike held out his hand for Sonic to shake it.

Sonic hesitated, then shook Ike's hand. "Pleased to meet you, too. How did you get here again?"

"I ran at the speed of light and I just ended up here." Ike replied.

"Then we should be able to go back that way, right?"

"I don't know. I would've still been traveling through time and space if I could. Maybe a rift happened due to my extremely limited magical ability. I mean so limited the most powerful attack I can do with it is shoot a medium powered lightning bolt at close range. My spin dash is much more effective in combat."

"So we need Shadow to be here and at least one emerald in our possession." Sonic said, disappointed.

"But how're we supposed to get an emerald?" Ike asked

"I don't know." Sonic replied.

"In the meantime, we need a place to stay." Ike stated.

"I have a spare two-person bed at my house," Twilight suggested. "And I guess I could figure something out for Tails. Does that suit your fancy?"

"Yep!" Ike and Tails said.

"Suit your fancy?" Sonic asked.

"It's a southern way to say 'is that good enough for you?'" Twilight answered.

"Well then, yes." Sonic answered.

"You sure you don't mind having to feed three extra mouths?" Ike asked.

"I'm sure Spike won't mind at all!" Twilight assured, smiling.

"Spike?" the three Mobians said at the same time.

"He's a little purple dragon who does my housework and such," Twilight explained. "Which reminds me, he should be back from those errands I sent him on." And Twilight and the three Mobians went to her house.
