Roy and co looked around.

"Ah yes, the Sonic world." Roy said.

"The question is, where's Sonic?" Popo asked.

"I also have a question. WHO is Sonic?" Steve asked. "Seriously guys, start explaining things more."

"Oh. Right. Sonic is a blue hedgehog who runs fast." Female Corrin explained.

"...weird." Steve commented.

Mario looked around. He started reminicing about the past. "Ah yes, Sonic and I go way back."

Tails appeared and ran up to the group. "Guys! Help! Sonic's gone crazy!"

"What?! Where?!" Roy asked.

Tails led the group to a city.

"Oh... my god." Female Corrin said.

Sonic is rampaging through the city.

"No CoPyRiGhT lAw In ThE uNiVeRsE iS gOnNa StOp Me!" Sonic proclaimed.

"What the heck..." Roy commented.

"He's been like this ever since Galeem and Dharkon took control of him!" Tails explained.

"Don't worry, foxy. We'll help!" Steve said as he drew his sword.

Sonic stepped up to fight.

Mario stepped forwards. "No. Let me handle this."

Battle 73: Mario 'Jumpman' Mario, A.K.A. Mr. Video Game Himself vs Sonic, the Blue Blur

Mario stepped forwards. "Sonic! We don't have to fight!" Mario exclaimed.

Sonic ran forwards and punched Mario in the stomach. "Well, I tried." Mario shrugged.

Mario then ran forwards, jumped high up, and slammed the ground. Sonic quickly dodged.

"SoNiC sPeEd!" Sonic proclaimed.

"Oh yeah?" Mario said. "Mario jump!"

Mario jumped high in the sky and attempted to land on Sonic. Sonic, seeing that coming, crouched.

"Yowza!" Mario exclaimed as he landed on Sonic's spines.

"CoMe On, StEp It Up!" Sonic proclaimed.

Mario looked around. He saw a monitor.

"Aha! A power-up!" Mario exclaimed. He ran for it and punched it, obtaining ten rings.

"...really? Just coins?" Mario disappointedly said.

Sonic then ran up to Mario and tried punching him. Mario did not get hurt, as he had rings on him.

"WoAh!" Sonic exclaimed.

"Woah! Rings are way better than coins!" Mario exclaimed. Mario took the opputunity to kick Sonic. 420 rings then all flew out of Sonic.

"AaAaAaHhHhH!" Sonic exclaimed.

"Now's my chance!" Mario said to himself. "It's time for my big attack!"

Mario did a very impressive punch.

Sonic stood up. "Wow. Thanks Mario! You... You saved me!" Sonic said.

"Hey. It's what friends do, Sonic." Mario said with a smile.

Sonic smiled.

"Hey, listen. I want to join the quest." Sonic said. "Galeem and Dharkon are no good."

"Welcome to the team, Sonic!" Roy said.

"Thanks Roy. Oh, and take this." Sonic said as he handed something shiny to Roy.

"It's the blue Chaos Emerald." Sonic said. "I mean, I've got speed, so I don't really need it. But you? What do you have? You better take it."

"Gee... thanks..." Roy said with emotional pain.

"Oh, and before I leave..." Sonic turned around.

"Silver, we still don't know where any of the other Chaos Emeralds are. You go look for them." Sonic ordered.

"What! Why me?" Silver whined.

"Because I said so.

"Fine..." Silver said.
