Akumas...

Devils that dwell within the hearts...

And inhabit the bodies of man and beast alike...

Now...

One man is about to make a deal with the Devil...

To destroy Satan himself...

"Contract complete!"

Rex Drake... a young man who works in his family bathhouse and made a deal with an Akuma!

"I got your back, sir!"

"What's going on here?!"

"Rex go for it!"

"Ah, now this is the life..."

And the Akuma who resides within his heart... Vice!

"HEY THERE!"

"ARGH! WHAT IS THAT THING?!"

"The name's Vice, and I'm the most powerful demon there is!"

"You were real this whole time?!"

"No shit, Sherlock!"

While Rex tries to figure out Vice, he strives to be there for his family...

Martin and Akira Drake, the owners of Happy Spa Days...

"Good job, everyone! Keep up the good work, honey!"

"I've got it, dear!"

The youngest daughter and younger sister of Rex, Diane!

"I'll handle it, bro!"

"Hands off, you wrinkled-old perv!"

And Rex's elder brother Kai, a volunteer for the Fenix Foundation who is secretly one of their recruits and soon-to-be captain!

"The mission is going smoothly, sir!"

"Bring down the Akuma!"

"Okay, Rex, now that I'll be gone more often, it's up to you to be the man of the family, can you do that?"

"Always big bro! And congrats!"

...And his friends: Derek...

"Yo, man wait for me!"

"Oh, the number of subscribers I'll have after this...!"

And Sarah!

"You can count me in! No way I'm letting some demons take our town!"

"Is he talking to Vice or to himself?"

"I dunno..."

Fighting against Rex and Vice are the cultists who worship the Akumas...

The Deadmans...

All in pursuit to revive their Demon master...

Gifu...

"Revi... and that traitorous Vice... they will soon pay with their very lives..."

And the Eggman Empire, led by the evil Dr. Robotnik from the world of Mobius...!

"I will find the Chaos Emeralds, and soon both Mobius and this world will be at my mercy! OHOHOHOHOHO!"

To combat the Deadmans and Robotnik, Rex and Vice will have to work with the Fenix Foundation, an organization posing as a technology corporation but secretly keeping the people of the world safe from the Deadman threat...

"Why not fight Akumas... with Akumas?"

"So sweet! Two Riders coming together for the coming battle! I must document this!"

And the Freedom Fighters of Mobius...

Sally Acorn, leader of the resistance and princess to the throne and her trusty A.I...

"Freedom Fighters, charge!"

"Nicole, scan the area for any kind of passageways!"

"Will do, Sally!"

Tails Prower, young pilot and aspiring inventor...

"My Tornado-X will get us there in a flash!"

"Nice one, Rex! I'll take it from here!"

Knuckles, treasure hunter and guardian of Angel Island...

"The Master Emerald helps keep the island afloat, but not if it's shattered!"

"Our only hope is to take out that ship before it hits the mainland."

Antoine D'Coolette, brave but timid captain of the guard...

"For ze honor of House Acorn!"

"Alright, tell me anything! Vhat does zat feul have that I do not?!"

"Ah, ve are doom-ed!"

Bunnie Rabbot, half rabbit, half robot, all cowgirl...

"Yeehaw! Time to wallop some Badnik ass!"

"Let's test these bad boys out!"

"Why, aren't you a cutie, Sugar-Rex?"

"Eh?!"

Shadow the Hedgehog, the Ultimate Lifeform...

"Behold, the ultimate power!"

"No way I'm working with someone like him..."

Rouge, the cunning thief and stealth operative...

"With Eggman destroying our world, this world's treasures are mine for the taking..."

"Now, don't you know it's rude to say 'no' to a lady?"

And many more to join the fight against evil...

"Quite the entourage we have, don't we?"

"You can say that again."

"Ah, who needs them, I can care of them all myself!"

"Oh, shut it, Vice!"

"Ow! Watch it, you!"

"Why I oughta-!"

...

"Is he okay?"

...

Join Rex, Vice and their allies in their battle against the Deadmans and the Eggman Empire as transform into a new generation of Riders...

With the heart and soul of humanity, Rex is Kamen Rider Revi!

And with the desire for a physical form and to wreak havoc, Vice is Kamen Rider Vice!

And together, they are

Revice!

"We are officially..."

"MEGALO-DONE!"

Kamen Rider Revice: Demons of Chaos!

Coming soon to a near you!

Let Chaos reign starting next week!

"The question remains, though..."

"If you were forced to do something you would never do... if someone you cared about was on the line... if you knew there was no going back but had no choice..."

"Would you be willing to make a deal with the Devil?"

HEDGEHOG!

A/N: Thank you all for reading this trailer for my new story. With luck, I will have it available by next week or so. BTW, I might be making this story a harem fic, with Rex being shipped with Mobian girls (no Elise, I can assure you all). Anyway, for this story, I'll be incorporating characters, events and items from various Sonic the Hedgehog games, tv shows, comics and movies. I will also be adding in Kamen Rider Arcs because of the Rider themes in Revice's forms and because it's an anniversary season. Be patient, my good people, and this story shall update soon enough! BYE!

P.S.: Sorry if this trailer seems a little messy or long. I kinda rushed it.

:-P
