(Ikari is seen at I-Island, where he is currently living as he remembers that he has to fight his former friend.)

Ikari: As much as I didn't want to do this... I made a promise, and I'll have to keep it.

(Suddenly he overhears something.)

????: What do you need exactly?

???? 2: We need you to track down Harley Quinn, and bring her to me!

????: I'm sorry for what happened in Metropolis. Everyone is, but it's possible that some of your teammates might betray you.

???? 3: How can you be so sure?

???? 2: By the way, how is Melissa?

Ikari: (whispers) Melissa? Melissa Shield?

(Then he slowly opens up the door and sees David Shield having a "talk" with Superman and Wonder Woman.)

David: Honestly, she's fine, but refuses to talk about heroes, just like Eri, Kota and Izuku.

Wonder Woman: Those three were like this for weeks. As for Izuku, I can't exactly blame him. That madman Shigaraki took someone important from him.

David: At least HE didn't use HIS loss to commit such atrocities you both have been doing lately!

Superman: (stern) Atrocities? We're...

David: You're scaring people!

Superman: GOOD! They're supposed to be afraid. Afraid to hurt each other, afraid to pull the trigger or click the button. One of our teammates taught us that.

David: At least BATMAN didn't kill a man!

Superman: The Joker was NEVER a man! He was a monster!

David: You CAN'T decide who lives or not!

Superman: Only one death!

David: It ALWAYS starts with one!

Wonder Woman: Look, David...

David: Only my friends call me David. It's Mr. Shield to you and your allies from now on!

Superman: WAIT!

(David hangs up and feels tired.)

David: I can see now why Izuku decided to become a vigilante.

Ikari: Mr. Shield?

(David turns to see Ikari.)

David: Who are you? Did Superman send you here?

Ikari: No, even thought I used to be his friend... not anymore!

???? 3: David.

(David and Ikari turn to see Izuku, Melissa, Eri and Kota.)

David: Oh, hey Izuku.

Izuku: Who is that guy?

Ikari: Oh, where are my manners. I'm Ikari Kido, and I am... used to be friends with Clark Kent... but I'm not anymore.

Melissa: What do you mean by "used to be"?

Kota: I guess he means that he's no longer friends with Superman.

Ikari: That's right. And I'm here to help you.

Eri: And how can you exactly help us?

Ikari: (pulls out his deck) With this.

(Suddenly an army or Regime Soldiers come in and surround the six, and then Superman, Wonder Woman, Cyborg and Raven.)

Superman: You should have agreed with my terms, David Shield, but it looks like I'll have to set an example out of you and your people!

Ikari: Not so fast, Clark!

Superman: (eyes widen) Ikari?

Cyborg: Friend of yours, Superman?

Ikari: (points the deck at a mirror) Once upon a time... I was...

(Then the V-Buckle appears in his waist.)

Ikari: Henshin!

(Ikari becomes Kamen Rider Ryuki.)

Ryuki: But now I'm his enemy!

Raven: If you're Superman's enemy... then you're OUR enemy!

Ryuki: (pulls out a card) Thought you would say that!

(He then places the card in his Dragvisor)

ADVENT!

(Then Dragreder comes out from the mirror and tailwhips Cyborg and Raven while Izuku prepares to deal with Wonder Woman.)

Izuku: I'll take care of the amazon. (to David) Take Melissa and the kids out of here!

Superman: (stern) I won't let you...

(Ryuki pulls out another card and places it in his visor.)

GUARD VENT!

(As Superman shoots his heat vision, Ryuki shields David, Melissa, Eri and Kota as they get to leave.)

Ryuki: You're taking the wrong path, Kal-El!

Superman: No... YOU ARE!

(Izuku tackles Wonder Woman while Ryuki pulls out another card and places it on his visor.)

STRIKE VENT!

(Ryuki then shoots a flame wave from his Dragclaw, and it hits him.)

Ryuki: Humans are NOT playthings, Superman! (Dragreder tailwhips Superman) And you are NO God!

(Ryuki pulls out a card and prepares to finish Superman.)

FINAL VENT!

(Cut to Izuku, he is seen slamming Wonder Woman into the ground as he sighs before leaving. Wonder Woman gets up, but as she is about to stab him, she has a feeling something might happen to Superman and decides to help Kal-El instead.)

(Back to Ryuki, he jumps into the air with Dragreder flying behind him. Dragreder then breathes fire at Ryuki, propelling him into a flying kick. As it's about to hit Superman, Wonder Woman gets in the way and shields Kal-El.)

Wonder Woman: (to Superman) GO!

(Superman sighs as he leaves. Noticing that he's leaving Ryuki kicks Wonder Woman, bringing her down.)

Ryuki: That's enough... for now!

(Then Ryuki goes through the mirror, leaving the building. The last scene shows Izuku arriving in a vehichle, where David, Melissa, Eri and Kota are waiting for him. Melissa has something in mind.)

Melissa: (in mind) Ikari...

(Then the screen fades out.)
