Sonic the Hedgehog found Tails and said, "Hey, Tails! I'd like to ask Knuckles some questions about how Eggman fooled him after he crashed the Death Egg onto Angel Island"

"You can take the Tornado since it's your plane," Tails replied.

"Ever since I met you, it seems to be your plane more than mine, so… can you fly me there?"

Tails flew the Tornado up to Angel Island while Sonic stood on the wings. Amy Rose, another hedgehog who was obsessed with Sonic, tried to follow him, but couldn't fly a plane to follow the Tornado.

When Sonic and Tails arrived, the former said, "Knuckles? Where are you?"

Knuckles, an echidna, came out of hiding and said, "What do you want? I'm on the lookout for more potential thieves of the Master Emerald,"

"How did you fail to notice Eggman's face on the Death Egg after it crashed into Angel Island… the first time?"

"I'm nearsighted. And I also thought it was the egg of Perfect Chaos, a being of apocalyptic power. From what I've been able to gather, four thousand years ago, my ancestors attempted to steal either the Chaos Emeralds or the Master Emerald. Or maybe they were after all eight. But Chaos used the Chaos Emeralds, which were then just called the 'Emeralds', to destroy them since they harmed the Chao. But even after wiping out the invaders, Chaos was still angry and wanted to destroy the world. So a more peaceful ancestor of mine sealed herself and Chaos in the Master Emerald,"

Tails said, "So… Perfect Chaos is to Chaos like Super Sonic is to Sonic? Did he use all of the Chaos Emeralds to transform?"

"I think so? He's been sealed for four thousand years and trying to release him would endanger the whole world, so I can't just check."

The three of them all felt like they were falling and so was the island. Eggman was once again stealing the Master Emerald. Knuckles said, "I shouldn't have talked to you two!"

Sonic chased Eggman, hoping to help. Since Knuckles was keeping up with him, Sonic asked, "Why did you believe Eggman's lies when you first met?"

"I didn't have anyone to talk to from the outside world for most of my life! At least, no one to talk to that could answer back! And for the record, after you destroyed the Death Egg, chased Eggman, and retrieved the Master Emerald, the one surviving Eggrobo from Sky Sanctuary stole it. But I tricked Mecha Sonic, which you disabled but didn't destroy in Sky Sanctuary, into destroying the Eggrobo. After I defeated it once, it used the Master Emerald to access its own super transformation, though it couldn't last and needed to recharge from time to time. I took advantage of those times to defeat it for good,"

"You know, Eggman has made quite a lot of robots that look like me. The first time I entered the Death Egg, I fought something Eggman claimed was called Robo Sonic. Or maybe that was also called Mecha Sonic. If so, would that make the one in Sky Sanctuary 'Mecha Sonic Mark II?"

"Maybe…? I don't know what 'Mark' means in this case,"

Sonic said, "I seem to remember saving Tails from a robot called Silver Sonic, but I could be remembering it wrong. But the one I remember the most is-" but Metal Sonic, the one Eggman used in his conquest of Little Planet, rushed towards Sonic. With an intimidating voice that was deeper than Sonic expected even for an intimidating voice, Metal Sonic said, "It's you!"

Tails was flying towards Sonic and Knuckles and said, "That doesn't look familiar,"

"Remember when I told you about my adventure on Little Planet? This is Metal Sonic," Sonic said. They felt a sudden impact, Knuckles realizing that Angel Island once again fell into the water. It didn't affect the life on or around the island too much, though. They heard a new voice approaching and realized Amy was coming. Metal Sonic said, "Even though Little Planet only arrives near this planet for one month of the year, Eggman located me after I lost the race at Stardust Speedway and restored me. I want to race you again, Sonic!"

Amy approached and tackle hugged Sonic. As she looked up, though, she saw Metal Sonic and remembered that he kidnapped her. Sonic said, "Get off me!"

She pulled out a giant hammer, but while Sonic feared for his life, she slammed the hammer between his legs and used it to bounce, not harming him. Amy said, "Metal Sonic… It's easy to remember what you did to me!"

Eggman showed up, holding the Master Emerald in a claw below the Egg Mobile. He said, "Knuckles, try to steal it again and I'll electrocute you like last time!"

Knuckles was going to shatter the Master Emerald into shards that he could reassemble but realized that would release Chaos. Sonic said, "Let's make a bet, Eggman!"

"My name is Dr. Robotnik!" he said.

"Anyway, if I can win another race against Metal Sonic, you have to return the Master Emerald."

"So if I- I mean Metal Sonic wins, I keep the Master Emerald, right?"

"It's a bet, so I suppose," Sonic said.

"Don't do it!" Tails said.

"Deal!" Eggman said.

The race was a single lap, full loop around the perimeter of Angel Island. Like the Stardust Speedway race, Eggman followed behind with a death laser strapped onto the Egg Mobile and Metal Sonic had two attacks he used in the race. But Eggman chose to play dirty besides the laser, leaving traps harmless to Metal Sonic but meant to kill Sonic. Tails, Knuckles, and Amy noticed this and cleared the path for Sonic. When they got to the finish line, though, it was too close to call and there were no cameras to take either still photos or video recordings.

"I won!" Sonic said after he crossed the finish line.

"No, I won, copy!" Metal Sonic said.

"You think I'm a copy of you?! Think about your name and mine!" Sonic said.

Eggman programmed Metal Sonic to prioritize proving his superiority to Sonic above all else. Even if Metal Sonic were to betray Eggman and attempt to take over the world, his motivation deep down would still be proving that he was better than Sonic.

Here and now, Eggman said, "Metal Sonic won, so I'll be off!"

"Hold it!" Knuckles said.

"The two finished the race and no one else saw it to confirm who crossed the finish line first, so how about we hold a vote to decide the winner since we can't agree? And Sonic and Metal Sonic won't participate because it's obvious they'd vote for themselves winning the race."

Knuckles, Amy, and Tails all voted that Sonic won the race while Eggman was alone in voting that Metal Sonic won. Tails said, "So much for that IQ of three hundred you claim to have, Eggman!"

Eggman said, "Mark my words, fox. One day, I'll deduce you hiding something like a fake Chaos Emerald from me and I'll trick you into confirming which Emerald is fake and which one is real."

Knuckles got the Master Emerald back in its rightful place and Angel Island ascended once again. Amy said, "Sonic, Tails, how am I gonna get back down?"

Tails knew Amy wanted to fly with him and Sonic, but said, "The Tornado only has one seat. Sonic has to stand on the wings! Do you think you can do that, too? If you fall off and hit the water, you may break lots of bones,"

Amy shuddered, but said, "We'll find a way!"

She sat on the tail behind the cockpit while Tails flew down and Sonic stood on the wings.
