Yugi had parked Slifer in Green Hill Zone, seeing a pink hedgehog and a tan rabbit eating ice cream under an umbrella. A yellow fox with two tails and a red echidna were with them.
"Oh, this is so lovely, eating ice cream under an umbrella, eh Mrs. Amy?" Cream was licking her strawberry ice cream cone.
"Gee, I wonder where Sonic is." Amy saw Sonic running from some crazed MotoBugs that looked angrier than usual. He smashed the badnicks.
"Sonic, where have you been!" Amy drew her hammer. "We were supposed to go on a date 30 minutes ago, but you stood me up!" Sonic looked up at the sky, and the sky turned red. The checkered squares of Green Hill Zone turned black and red, the green grass turned milky white, and the pink flowers turned into snake heads that spit venom. The yellow sunflowers turned into cobra heads that spit fire.
"Green Hill is looking a lot like Blood Hill right now." Sonic watched as the water in Green Hill turned bloody red. "I bet Dr. Eggman is behind this." Sonic looked at Yugi and Harry.
"Who are you guys?" Sonic asked.
"I am Harry Potter, and this is my friend, Yugi." Harry introduced himself.
"Cool." Sonic answered. "I am Sonic the Hedgehog, the fastest thing alive!"
"Bet you're not faster than my Firebolt!" Harry called his Firebolt with his Accio spell. "I'll race ya!"
"Go, Polymerization!" Yugi announced. "I fuse Dark Magician with Dark Megacycle to form Dark Magician Cycle!" Yugi hopped on his purple motorcycle. Yugi, Harry and Sonic raced each other.
"Last one to Eggman's base is a rotten Egg Pawn!" Sonic announced. He had the lead in first place, but Harry bumped him. Yugi plugged his Duel Disk into the Dark Magician Cycle.
"I activate my Boost Spell Card, making me accelerate at 90 miles per hour!" Sonic ran at 100 miles per hour, outrunning Yugi. Harry was in last place. Yugi was about to draw a card, but Harry drew his wand.
"Expelliarmus!" Harry cast, making Yugi drop one of his cards.
"Aha, you activated my Trap Card!" Yugi had a trick up his sleeve. "Behold, Disarm Shock! Whenever the card falls out of my hand, you lose half your Life Points!" Harry was electrically shocked, making his life points go from 4000 to 2000. "As for you, Sonic, I activate the Spell Card Copycat, that makes me copy one of Harry's spells." Yugi drew a wand. "Arresto Momentum!" Yugi slowed down Sonic's speed. When all three got to Eggman's base, Eggman was held at gunpoint by Pandora's goons.
"Pandora!" Yugi gasped.
"You know this lady?" Sonic saw the woman pointing her staff at Eggman, and her robotic ninjas pointing their laser guns at Eggman.
"Come out, my Egg Pawns!" When Eggman's Egg Pawns arrived, Pandora's most trusted minions arrived, Sylvie, Shirley, Seth, Steve and Sylar, all of which had a name that started with the letter S because they were part snake.
"Go my robots, attack them!" Eggman commanded.
"Not so fast!" Sylvie snapped her fingers, reprogramming the robots to obey Pandora instead.
"All Hail Pandora!" An Egg Pawn said in its robotic voice.
"You won't get away with this!" Sonic smashed the robots and cut Eggman free.
"What is your plan, Pandora?" Sonic interrogated Pandora. "What are you going to accomplish with this?"
"My plan is to destroy the multiverse because I have traveled to various worlds and all I have seen is war, death, and violence. I want to destroy the multiverse to create one sole universe free of war, violence, hate, and bigotry, one free of all the bad stuff in all the universes, a utopia, if you will."
"But if Sonic's world is destroyed, I will have no world to rule!" Eggman gasped. "I will join your team Sonic, but I will be fighting on the home ground for the resistance forces backed by GUN. Therefore, you will go on your journey without me. I have enough to worry about. Sonic, Harry and Yugi decided to continue onward. Yugi summoned Slifer again, and all three of them took off and headed to wherever Pandora would attack next.
