Sonic x RWBY: Huntresses of Mobius

Stage 1: Arrival

In Eggman's base, the brilliant doctor himself made a machine that makes wormholes from another dimension using the power of the seven chaos emeralds. The doctor laughs as he inserts all of the emeralds into the machine. "Finally... After every attempt to collect all the chaos emeralds from that little blue pin cushion, I've made my greatest invention yet. All I have to do is activate Chaos Control and a portal to another dimension will open up. I won't just rule this universe, but every other universe!" He said with a maniacal evil laugh.

In the middle of Eggman's laugh, the alarms in his base go off, indicating that there is an intruder. The doctor checked the cameras outside his base to notice a blue colored hedgehog, a two-tailed fox, and a red echidna destroying the doctor's robots that were guarding the entrance of the base. The doctor groans. "Not that pesky hedgehog and his pals again." Eggman said as he pushed a big square shaped button to activate the defense systems inside his base. "Haha! Let's see that blue pest get the best of me now!"

The blue hedgehog managed to break through the entrance. This hedgehog's name? He is Mobius' hero. He is Sonic the Hedgehog. He looks around the entrance that he just busted through. "So far so good." He said feeling chipper about himself. The defense system Eggman recently activated kicks in as a group of Eggman robots and a turrets appeared. The red echidna, Knuckles rushed towards Eggman's defenses and punched his way through the robots. The two-tailed fox, Miles 'Tails' Prower hacks the turrets. This hack also caused the doors to where the chaos emeralds were, the doors to the generator room, and the doors to the main hangar to open. The three run quickly to where the doctor was holding the emeralds.

"It's too late Sonic! The machine is fully charged! All I have to do is push this button." The doctor said hovering his finger over a big red colored button. Sonic curls up into a ball as he prepares for a spin dash until the doctor pushed the button. The emeralds glow. Sonic stopped as him, Knuckles, Tails, and Eggman witnessed Chaos Control. However, they weren't brought to Earth this time. The emeralds stop glowing as almost nothing happened. The doctor was shocked as he began pressing random buttons on the machine. "Heh... Looks like you have to go back to the drawing board this time Egghead." Sonic said with a snicker.

The doctor growls as he pressed the red button again, but this time the machine blows up. Eggman coughs as he looks Sonic, Tails, and Knuckles. The three were laughing at the doctor. Eggman was now steamed. "I'll get you one day blue hedgehog!" He said as he jumped into his Egg Mobile and flees. "We should probably get the emeralds." Tails said. Knuckles approached the machine. "The emeralds are gone. I must be because of Chaos Control." Knuckles stated as Sonic nods in agreement.

Mean while in a different dimension. A few minutes before Chaos Control was activated, there were four girls who arrived at their dorm room after a field trip from Forever Fall. One girl has silver eyes, black colored hair, and wears a red hood with a cape. Another girl has white hair that is pulled back into a ponytail. A girl with raven colored hair wearing bow. And lastly, a blonde hair girl. These four girls are named Ruby Rose, Weiss Schnee, Blake Belladonna, and Yang Xiao Long. They're also known as Team RWBY. The four girls were getting ready to go sleep. However, a portal opens in the middle of their dorm room. The sucked up the four girls like a vacuum and brought them in the middle of a luscious green forest.

"Is everyone okay?" Ruby asked as she dusts herself off. Blake helps Yang up as Weiss looked at her partner. "Of course we are. But where are we? This doesn't look like the Emerald Forest." She stated. Blake noticed a small glimmer in the distance. She back and grabbed her weapon, Gambol Shroud from the metal plate on her back. Ruby, Weiss, Yang looked at Blake. "What's wrong?" Yang asked. Blake points to the small glimmer of light that was looking at. The Team RWBY noticed it.

Ruby approached the glimmer. The small white glimmer became a big red light as Ruby noticed a red gem. Her eyes widened as she picked up the gem. "Hey guys I found a jewel." She said which caused Blake to stand down and place her weapon back on her back.

Team RWBY looked at the red gem. "I've never seen a dust crystal that big before." Weiss said as she felt like she was in some sort of trance. Yang looked at the gem. "I wonder who would leave something like that here." The blonde takes the gem from her little sister for a more closer look. Blake noticed the moon in the sky. Her eyes widened at what she saw. "Uhh... Guys." She looks at her teammates and back up at the sky. The rest of Team RWBY looked at the sky too. They were shocked to see the moon. It was full and not shattered. What could this mean. Did they go to the past? Or are they in an alternate dimension?

Mean while at Eggman's base, Sonic and Tails looked at the doctor. "Looks like you have to go back to the drawing board Egghead." Sonic said with a smirk which cause the doctor to groan in annoyance. Knuckles exits the main control room and enter the generator room. Inside, Knuckles could see his Master Emerald. "Once I get this back to the shrine on Angel Island, me and Eggman are gonna have a little chat." He said angrily as he picked up the Master Emerald with both of his hands as Sonic and Tails exited the base. Sonic looks back at Knuckles. "I see you got what you came here for knucklehead." Sonic said with a chuckle and a smirk.

"Sonic!" Tails yelled as he pointed to a portal in the distance. Sonic and Knuckles noticed the portal. Sonic smirked and runs to where the portal opened. "Sonic wait up!" Tails said as him and Knuckles followed their blue hedgehog friend.
