(After dealing with Fourth Kind, Vanisher and Twice, the heroes proceed further into Hawkmoth's mansion.)

Kiva: So? Do you have any idea who we will be facing next?

Ex-Aid: We'll probably be facing four opponents, two villains and two former heroes.

Kivala: I wonder who will show up.

Izuku: There's a big chance that we'll be facing Spinner, Mr. Compress, Backdraft and Kamui Woods.

Banjou: Weren't those two former heroes the very ones who scolded you when you tried to save that bastard?

Ochako: Indeed they are.

Momo: They will be tougher, but I am 100%... no, 1000% sure we can beat them.

Zoey: As long as we work together, there's nothing to worry about.

(Then Ex-Aid stops walking.)

Hajime: Something wrong?

(Ex-Aid looks up.)

Ex-Aid: Look out!

(Then the heroes see a rock falling from above, and dodge it. As they land, they hear a voice.)

????: Took you long enough.

Izuku: I should've known it was you. Now why don't you show up along with your old and new friends so we can get this over with.

(Then Spinner, Mr. Compress, Backdraft and Kamui Woods come in.)

Spinner: So we meet again, Dekusquad.

Backdraft: Where is Fourth Kind? What did you do to him?

Ex-Aid: He's dead. He was killed by Izuku.

K. Woods: How could you do this, Deku?

Izuku: I did this because he knew the consequences of his actions for joining Hawkmoth.

Banjou: He's not the only one. Vanisher is dead too.

Backdraft: (points at Tsubasa) And she let this happen like it wasn't her problem?

Tsubasa: Why should I forgive a traitor like her? She made her choice once she believed at Lila's lies and joined Hawkmoth. The only friends I have are Zoey, Kagami, Nino, Ayla and Luka.

Spinner: Enough talk. You're dealing with us now.

Ex-Aid: Alright. D~a~i Henshin!

G. Driver: Gachan! Double Up! Ore ga omae de! Omae ga ore de! We are! Mighty Mighty Brothers! (Hey!) Double X!

Mr. Compress: So it's Kamen Riders I must face, huh?

Ex-Aid: Indeed.

Vulcan: Let's get this over with.

(Then Spinner rushes at Vulcan, who punches him away, and charges at him. Zero-One and Kiva dash at Mr. Compress while Valkyrie fights Backdraft.)

K. Woods: You will fall!

(Kamui Woods tries to use his quirk, but Ex-Aid kicks him.)

Ex-Aid: You're not harming anyone!

(Thouser and Kivala charge at Kamui Woods and manage to hit him with their combined attacks.)

K. Woods: Damn you!

(Kamui Woods blindly rushes at them, only to be stopped by a kick from OOO)

(Then the riders (except for Kiva, Kivala and Vulcan) undo their transformation.)

Kagami: Well, they're gone. But who will we be facing next?

Vincent: There are still seven villains and seven former heroes.

Izuku: Yeah, but I know we can overcome obstacles together once and for all.

(Then the heroes proceed further as the screen fades out)
