Previously...

Sonic and Y/N steps back a few feet but stops at the edge of the roof, and they see a flying aircraft overhead, which is Dr. Robotnik's Eggpod. The ship hovers over to the four and the cockpit opens, revealing Robotnik in an entirely different outfit and with an evil smirk on his face.

"Welcome to San Francisco, Mr. Wachowski. Are you enjoying the clam chowder?"

Tom mumbles to Maddie.

"It's the government whack job who keeps trying to kill us."

He then turns to Robotnik.

"Unsuccessfully!"

The remark makes Robotnik scowl.

"Nice of you to swing by on your way to Comic-Con." Tom said.

"Yeah, what are you wearing?" Maddie asked.

"Some sort of jumpsuit?" Y/N joked, making Sonic and Tom snicker.

Dr. Robotnik looks at his suit and then back to the four.

"It's a flight suit, designed to modulate my body temperature and reduce" he finished through clenched teeth. "drag!"

"Yeah, and you still are one." Tom remarked.

"Oh-hoo! Good one. You are catching fire, Thomas. Oh, and speaking of heat, I see you've taken a lover. Does she have a name, or should we just call her "collateral damage"?"

Dr. Robotnik chuckles and drums the sides of the Eggpod with glee.

"Hey, watch your mouth! Unless you want a little more of what I gave you earlier."

Tom turns to Maddie again with a smile.

"I punched him in the face."

"You punched him right in the face! It was awesome!" Sonic laughed.

"It was pretty funny!" Y/N laughed.

"The time for talking is over! It's time to push buttons!" Dr. Robotnik shouted through his clenched teeth.

"Your flying eggs are pretty impressive, Mr. Eggman, but let's face it, you'll never catch me or sis!" Sonic mocked.

"Confidence! A fool's substitute for intelligence."

Robotnik opens a button capsule as the energy from Sonic and Y/N's quills powers the Eggpod and the flying drones ready their weapons as well.

"That's not good." Sonic commented.

"Sonic, Y/N, I know you two got the super speed and everything, but Maddie and I--" Tom started.

"Totally defenseless? Probably gonna get blown up?" Y/N guessed.

"Pretty much, yeah." Maddie nodded nervously.

"Don't worry. I know exactly what to do."

Sonic jumps up to the side wall and jumps forward, pushing Tom and Maddie off the roof, and they scream.

"Sonic!!" Y/N turned to her brother in disbelief.

Sonic raised his hands up in surrender.

"What?? I said I know what to do!"

Robotnik looks down from inside the Eggpod, feigning shock.

"I was not expecting that... But I was expecting not to expect something, so it doesn't count."

The flying drones fire their weapons at Sonic and Y/N, but now time seems to have stopped and everything is frozen in place as Sonic's awareness is increased and he stands there, tapping his foot and looking at his wrist. He grabs frozen Y/N and makes her wrap her arms around his neck for her to hold. He then plays around with some of the missiles and bullets from the Egg Drone weapons and is able to destroy most of them. But Robotnik pushes the button and the quills fully charges the Eggpod and grants him supersonic speed. Sonic is makes a shooting hands gesture to two more Egg Drones, but Robotnik fires a laser blast at the blue hedgehog, which he barely escapes from, causing him to enter slight delirium. Sonic recovers from his trance to find Tom and Maddie still falling with Y/N falling beside him screaming and tries to reach for a Ring.

"Come on!"

Sonic tries air swimming to reach the Ring.

"Come on, come on, come on!"

"Hurry!!" Y/N shouted.

Sonic plucks one of his quills out and uses it to grab the Ring and he speeds towards the falling couple and tosses the Ring, opening a portal to a barn for them and they land safely in piles of hay while Sonic loses control.

"Whoa, whoa, whoa! No, no, no!"

Sonic hits several tree branches and lands on the ground, rings and rubble scattered everywhere. Y/N manages to grab onto the branch of the tree and landed in a pose.

Sonic recovers from his fall but notices Robotnik hovering in the air. Y/N immediately got into her fighting stance.

"Can I give you two one genius piece of advice? Don't run. It'll only hurt more if you do. And it's bad for your joints, they proved it."

"Alright, Eggman. You wanna get fast? Let's get fast!"

Sonic scrambles quickly to gather up all of his Rings and speeds off down the street. Y/N qyickly activates her roller blades from the bottom of her boots and her rockets before speeding off after her brother.

Dr. Robotnik puts on his flight goggles.

"The hard way it is."

The cockpit to the Eggpod closes and Robotnik gives chase to Sonic and Y/N, firing laser blasts at them, only to damage certain road sections. He turns left to continue the pursuit.

"That was an illegal left, by the way!"

The same freeze from from the beginning of the film is shown and Sonic and Y/N picks up the story.

"So, here we are again! We've been through so much together! Now you understand why there's a psychotic robot doctor chasing a supersonic blue hedgehog and super powerful light blue hedgehog." Sonic narrated.

"Want to know how it ends? Yeah, me too." Y/N narrated.

The pursuit continues as Sonic and Y/N continues to dodge laser blasts from Robotnik, even sliding under a large trailer to avoid them. Y/N brought out her wooden katanas to deflect every laser blasts that were being thrown at them, not caring if they're beginning to burn since it's made of wood.

"How is this possible?! No one's ever caught up to me before!" Sonic exclaimed.

"It may have something to do with the quill I saw earlier in his jet! He even have my quill!!" Y/N exclaimed, pulling out her green emerald whip for her to swing herself using the light post.

Sonic holds a ring, planning the next location.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Paris, France

A mime is entertaining a little girl and her mother. When the mime makes a circular movement with his hands, a Ring portal opens up behind them, and Sonic and Y/N zips through.

"Coming through!"

"Excuse us!!"

Robotnik follows behind and the mime moves out of the way.

"Sacrebleu!" Mime exclaimed.

"Excusez-moi, monsieur!" Robotnik laughed.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

China

The pursuit continues along the Great Wall of China.

"Here we go! Room to open it up!"

The trio increase their speed until Sonic tosses another ring, opening a new portal.

"We can't lose him!"

"We just gotta keep going!"

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Egypt

Robotnik fires multiple laser blasts from the Eggpod, destroying century-old monuments in its wake. Sonic and Y/N skids to a stop in the sand.

"If you can't beat 'em, blind 'em."

Sonic catches up to Robotnik and uses his speed to create a whirlwind of sand, with Y/N following him and helping him by spinning her whip to blow the sand, which disrupts Robotnik's visual contact.

"Lost... visual contact!"

He then sees Sonic and Y/N speed up the Great Pyramid of Giza.

"You're not allowed up there! It's one of the Seven Wonders!"

Robotnik blasts out of the whirlwind, and just as Sonic opens another ring portal, Y/N noticed Robotnik and tried to activate her power from her emerald necklace as she managed to create a green crystal-like shield.

Robotnik them fires a laser blast at Sonic and Y/N, sending them flying through the portal and hurtling them onto the streets of Green Hills where Sonic lays motionless and unconscious while Y/N groans at the pain she felt as her shield disappears, leaving her unmoving. Robotnik menacingly appears through the portal as it closes. Tom, Maddie, and the farmer rush to see what the commotion is all about when Robotnik cackles loudly and takes off his flight goggles.

"You two're an astonishing little creatures! It'll be fun to take you back to the lab for a litany of invasive exploratory procedures. Any last words?"

With his remaining strength, Sonic spoke up.

"Guac... I like that word..."

Sonic slumps over on the ground and Y/N glares up at Robotnik.

"Screw you, Eggman."

Just then, Tom appears behind Robotnik via a Ring portal.

"I don't have to tell you how many scientific breakthroughs have been made possible by animal testing. You're being very selfish."

"Going my way?"

Robotnik notices Tom.

"What the--"

Tom punches Robotnik, knocking his flight glasses off his head, and the two start fighting inside the Eggpod. Robotnik grabs Tom by his shirt.

"Who the hell do you think you are?!"

Tom breaks free and punches Robotnik again and grabs him.

"I'm the Donut Lord, you son of a--"

Tom gets elbowed by Robotnik and he is thrown off the Eggpod when Robotnik jerks the steering yoke and Tom lands on the ground.

"Autopilot, adjust!"

Robotnik puts his flight goggles back on his head and Maddie rushes to Tom.

"Why? Why would you throw your life away for these...things? That's why I don't have friends. Next thing you know, you're somebody's best man, they want to have the wedding out of town... Like nobody has anything better to do! Anyway, where were we? Oh, yes--you were about to die."

Suddenly, a bullet ricochets off the Eggpod and we see that it was Wade who fired his gun.

"That's our sheriff you're messing with."

Tom looks up as some of his friends join Wade.

"And our Blue Devil and Light Blue Angel,"

Carl holds up a chainsaw.

"who, as everyone can see, is a very real creature and not at all invented by me!"

Wade gently pushes the chainsaw away.

"Careful. Just-- just put it away."

Maddie looks over to an unconscious Sonic and an unmoving, hurt Y/N.

"Tom?"

Tom also sees Sonic unconscious and Y/N hurt in the street, and both of them feel the grief and guilt. He then noticed Y/N's guitar case that was moved away from her along with her two wooden katanas that are now burnt and broken from the blast she took.

"I don't mean to be indelicate here, but someone should get some ice, keep the bodies fresh."

Tom lowers his head.

"They're just silly little aliens. They didn't belong here!"

Tom looks over at Robotnik and stands up.

"Those little aliens... knew more about being human... than you ever will. Their names are Sonic and Y/N. This was their home... and they were my friends."

Upon hearing Tom's speech, Sonic immediately opens his eyes and stands up as his body is now supercharged with his energy, not only that but Y/N's body began to heal as the green energy coming from her necklace is covering her and her body glows light green, now up and feeling powered, leaving Dr. Robotnik bewildered, and Tom and Maddie smiling.

"He's all yours!"

Tom leads Maddie out of the way.

"Everyone get back!"

Everyone else moves out of the way.

"I think you have something that belongs to us!"

Sonic clenches a fist, which starts to siphon the energy from his quill in Robotnik's Eggpod until it is no longer glowing and the energy has now been transferred back to Sonic. Y/N did the same as her eyes glowed emerald green and the energy from her quill transferred back to her as they flow into her chest.

"This is our power, and we're not using it to run away anymore. We're using it to protect... our... friends!"

Dr. Robotnik puts on his flight goggles and readies the Eggpod's concealed weapons, the laser markers pointing at Sonic and Y/N, who sets a start position on the road. Robotnik smirks and fires the weapons and Sonic and Y/N leaps into action, dodging the projectiles and starts to bombard the vehicle with body slams, each barrage increasing in speed until the Eggpod is now disabled, which infuriates Robotnik.

"Now, you've done it!"

"Guess what, Eggman? We're not leaving Earth. YOU are!" Y/N grinned.

"Donut Lord?" Sonic called.

Tom nods and takes position behind Robotnik and throws a Ring, opening a portal to the Mushroom Planet. Then, both Robotnik and Sonic and Y/N charge at each other, but with Sonic and Y/N landing a powerful blow to the Eggpod, sending it and a screaming Dr. Robotnik through the portal and it closes, sealing Robotnik away. The electricity emanating from Sonic fades away along with the green energy flowing back into Y/N's necklace as her eyes went back to normal F/C, with the crowd cheering for Sonic and Y/N's victory as Tom reunites with them.

"I told you, you got this."

"Hey, WE got this."

Tom holds his hand up for a high-five, which excites Sonic so much, he happily laughs and runs around in a circle at super speed before jumping up and giving Tom a high-five. Tom turns to Y/N for a high-five next, but instead he received a hug from her, surprising him before smiling and hugging her back. Tom hands the Ring satchel back to Sonic.

"I think these belong to you."

"Thank you very much."

Before Tom can give Sonic the Rings, he makes one final "rule".

"No more pushing people off buildings."

"Yeah, Sonic." Y/N glared at him.

"You know I can't promise that." Sonic stated, making her glare even harder.

Tom give the Ring satchel back to Sonic.

"You two did pretty good, space 'hogs."

"Thanks, Donut Lord." Sonic said.

"You're gonna have to explain this "Donut Lord" thing." Maddie said.

"Nope, sorry." Tom said, making Maddie laugh.

"That's between me and the little guy. Right?"

Sonic nods, while Y/N rolls her eyes.

"We got our own thing, you got your thing with your... sister."

"Oh, my God, my sister." Maddie gasped, forgetting about Rachel.

Meanwhile in Rachel's house, Jojo runs around the house while Rachel is still tied up.

"Gotta go fast! Gotta go fast! Gotta go fast! Gotta go fast!"

"Jojo, put on my Fitbit... so I can at least get some steps." Rachel mumbled.

Back in the night of Green Hills, Montana

"We can never go back there. I kinda feel like I checked the "save a life" box off my bucket list. Now all I want to do is spend my life with the people I care about. I want to check that box." Sonic said.

"Alright, everybody. Nothing to see here. Let's disperse." Wade said, backing everyone away as they go back to their normal routine. "Come on, let's go! You act like you've never seen a fight between an intergalactic space rodents and a robot with a doctorate!"

"Oh, you might need these back."

Maddies brought out her damaged guitar case towards Y/N.

"Thank you, Maddie."

She opens it to see her blue electric guitar safe and sound and unscratched, making her feel relieved.
