(Ryo Shimizu is seen in the hotel, relaxing in the couch until he heard some knocks in the door. He opens the door and sees a box. Once he opens, he sees a watch similar to Ben 10's Omnitrix with a note.)

C. Virgo: Dear Ryo Shimizu, I'm giving you this Omegatrix. It can turn any hero into different aliens. I got you a book as well, so you can see their names and skills.

Shimizu: Thanks, Cosmic Virgo.

(Then he looks at the Omegatrix and sees a screen with some mugshots.)

Shimizu: Wow, that's cool.

(Then Nightwing comes in.)

Nightwing: Oh, you have your own Omnitrix.

Shimizu: It's the Omegatrix. It can turn any hero into an alien.

Cassie: Really?

(Then Yang has an idea.)

Yang: (presses one of the buttons) How about you become this tiny cutie here.

Shimizu: Yang, wait.

(Yang presses the Omnitrix, and giggles at Shimizu (as Grey Matter), and then she picks him up and puts him between her boobs.)

Yang: (giggles) You're so cute, baby. How about these girls here yang you?

Cassie: Ugh, did someone tell you about your puns being awful.

Yang: Say that again.

(Shimizu (as Grey Matter) manages to escape, and reverts back to normal while Yang and Cassie start fighting.)

Ruby: Are you okay, Shimizu?

Shimizu: Tell your sister that wasn't funny.

Ruby: That was filth indeed.

(Meanwhile, Oscar and Koga are seen in the store buying some stuff, without even knowing that two individuals are watching them.)

Noah: Remember, we must act naturally.

Reiko: Copy that.

(Some minutes later, Oscar and Koga have already bought some stuff to eat, drink and watch movies.)

Oscar: Well, that's all of the stuff.

Koga: Let's head back.

????: I don't think so, Special Forces.

(Then the two turn to see Noah Kaminari and Reiko Yanagi.)

Oscar: I'm sorry, but who are you.

Noah: I am Noah Kaminari, and this is Reiko Yanagi. We are the heroes of U.A. University.

Koga: Are you friends with someone known as Kamen Rider Zolda?

Reiko: Yep. I am one of his girlfriends.

Noah: Headmaster Nezu wants to see you.

Oscar/Koga: Sorry, but we rather kick your ass instead. Let's do this.

(Then Noah and Koga prepare to transform.)

Koga/Noah: HENSHIN!

Mr. Belt: Drive: Type Speed!

(Koga transforms into Kamen Rider Nigo while Noah becomes Kamen Rider Drive.)

Drive: Let's dance.

(Then they charge at each other. Oscar punches Reiko while Nigo kicks Drive. Then the two charge at them again, and suddenly Oscar feels something in his pocket, and then he picks it up.)

Oscar: How did I get it?

(Nigo kicks Drive and Reiko, and then he turns to Oscar.)

Nigo: How did you get that?

Oscar: I don't know... but maybe I should try it out. Magical Source, Mystic Force!

Morpher: Galywit Mysto Ranger!

(Oscar becomes Red Mystic Ranger.)

R. M. Ranger: That's badass. I'm a mystical Power Ranger. 🎵 Behold the wizard. Beware his powers. Unspeakable powers. 🎵

Nigo: Alright, let's show them what the Special Forces is made of.

R. M. Ranger: Right.

(Reiko and Drive get back up, and get shocked by seeing Oscar's Ranger form.)

Nigo: Are you ready?

R. M. Ranger: Let's do this!

(Red Mystic Ranger charges at Reiko, who uses her quirk to levitate some objects, but he slashes them, and then he slashes through her, knocking her out. Meanwhile, Drive and Nigo prepare their finishers.)

Mr. Belt: Hissatsu! Full Throttle! Speed!

Nigo: RIDER KICK!

(Then they jump and kick through each other, but both revert back to normal as Noah sees Reiko down.)

Noah: Round 1 goes to you... but we will meet again.

(Then Noah carries the unconscious Reiko and leaves.)

Oscar: That was awesome.

Koga: Can't wait to tell the others.

(At U.A. University, Kenji finds out about Reiko's defeat.)

Kenji: So they're stronger than I thought... Very well... Kira, you'll be going after them.

Kira: Roger.
