(At the Special Forces Base, Sonya and the other members, including the three Kamen Riders are present in a meeting where Sonya clicks a button, and Deathstroke's mugshot appears.)

Sonya: It's been a week since Slade Wilson, also known as Deathstroke was last seen.

(Then she clicks another button, and an holographic miniature of Vienna.)

Sonya: He lately tried to kill the Star City's Mayor.

Shimizu: Oliver Queen, also known as Green Arrow.

Sonya: And it looks like he's hiding in an apartment. Since Nightwing is busy helping Batman on Arkham Asylum, Deathstroke became our business now. Jaune, Shimizu, Koga. You're going after Slade.

Shimizu: Roger. We won't disappoint you, commander.

Sonya: I'm counting on it.

(In Vienna, Deathstroke is seen hiding from the cops with the help of Lex Luthor.)

Deathstroke: Why wasting your time with me? If I remember, you have a company to...

Lex Luthor: The Special Forces will come here soon.

Deathstroke: I thought you were worried about the Justice League.

Lex Luthor: The Special Forces have some powerful allies. Even more powerful than the Justice League, making Superman and Batman look like cards out of the deck.

Deathstroke: I know two of them. I was in there.

(Slade then grabs a backpack from under the floorboards and throws it out of the window. Slade and Luthor get behind Luthor's force field to avoid gunfire. Slade knocks a cop over and holds up his sword to repel bullets, then slams a cop into shelves. Slade picks up a large cement brick and slams it into a cop. Luthor fights a cop on the balcony. A cop shoots around the door outside. Slade punches through the wall beside he door. He lays into the cops. A cop descends through a sky-light on a zip wire. Slade grabs the cop's gun and slams him into the wall. Slade bashes a couple of cops with the battering ram. More of the police team hurry up the stairwell. Slade jumps on the zip-line-guy and swings down a level. The three Kamen Riders come in.)

Ichigo: Where is Slade?

(One of the police officers clicks a button in his wrist, and reveals to be Cyborg in disguise.)

Nigo: Cyborg?

Cyborg: Slade has broken containment! He's headed down the east stairwell!

Super-1: We'll go after him.

(Then Lex Luthor comes in and tries to shoot the heroes down, but Cyborg shields them as Luthor escapes.)

Cyborg: Lex Luthor?

(Then the Kamen Riders go after Deathstroke, Cyborg communicates with Superman.)

Cyborg: (commlink) Cyborg to Superman. I found Lex Luthor in Vienna helping Slade.

Superman: (commlink) Don't let him out of your sight. I am on my way.

(Deathstroke grabs his package, but Kamen Rider Super-1 slams into Slade from behind, knocking him down. He attacks Slade with sweeping kicks and punches. Slade fights back but is kicked into a wall. Luthor looks down at them as Sinestro swoops from the sky.)

Lex Luthor: Sinestro, southwest rooftop.

Sinestro: Who the hell are those three scums?

Lex Luthor: They're Kamen Riders.

(Luthor leaps from the balcony down onto the neighboring building as a chopper flies up. Kamen Rider Super-1 lunges at Slade with his fist, but Slade grabs his wrists. A soldier fires a machine gun from the chopper. The ammo bounces off Kamen Rider Super-1's armored suit.)

Lex Luthor: Sinestro.

Sinestro: Got him. (Sinestro flies down and with an axe construct, he cuts the chopper down. Fortunately Kamen Riders Ichigo and Nigo save the soldiers in time while Sinestro swoops towards street level.)

(Slade breaks free from his attacker, slings his bag on his back, runs and jumps down a level. Kamen Rider Super-1 slides down the wall. Back lands at street level and the chase continues. Luthor follows and lands rolling along the ground. Gunfire from the chopper tears up the sidewalk. Slade jumps down through an opening and lands in an underpass, he runs through the traffic. Kamen Rider Super-1 and Lex Luthor drop down and chase after Slade. A Special Forces Vehicle pursues them.)

GSG-9 Driver: Stand down! Stand down! (The vehicle closes in, blue lights flashing. Luthor leaps onto the vehicle and splinters the windshield. The driver stops, Luthor yanks him from the vehicle and kicks the windshield out, then drives off.)

(Slade runs over the top of a speeding car, outpacing it. Kamen Rider Super-1 is a few cars behind, keeping pace with Bucky. he leaps on the back of the 4x4 that Luthor's driving. Luthor swerves from side to side, trying to throw him off.)

Lex Luthor: Sinestro, I can't shake this guy.

Sinestro: Right behind you.

(Several police cars join the chase. Luthor side-swipes another car and drives on.)

(Up ahead Slade reaches a fork in the road and faces oncoming traffic. He leaps over a barrier. Luthor drives through the barrier.)

(A motorbike speeds towards Slade. Slade grabs the handlebar and spins the bike around in mid air, throwing the rider off. Slade gets on the bike and rides away sending cars careering out of the way. Luthor keeps on Slade's tail with Kamen Rider Super-1 holding onto the back of the 4x4. They all rocket through another underpass. Before Sinestro could fly into the underpass, Twi Pneuma kills him. Back to the chase, Kamen Rider Super-1 leaps off the front of the 4x4 onto Slade's motorbike. Slade flings him over his head and the bike leans down on its side. Slade kicks his assailant away, straightens up and rides on. Then Starfire comes in.)

Starfire: Need any help, friend Jaune?

(Kamen Rider Super-1 catches a ride on Starfire. Lex Luthor tries to shoot them down, but as they pass through, Superman comes in and uses his heat vision to blow up the roof at the end of the underpass, bringing down tons of rubble, blocking Lex Luthor's passage. Back to the chase, Kamen Rider Super-1 leaps off from Starfire and throws Slade off the motorbike.)

Super-1: This is the end for you, Deathstroke!

(Then Kamen Rider Super-1 executes his Super Whirlwind Kick, and destroys Slade. Then Superman comes in, grabbing Lex Luthor.)

Superman: Congratulations, Luthor. You showed your true colors.

(Some hours later, Lex Luthor is arrested for helping Deathstroke.)

(In a rooftop, Jaune is seen with Kung Jin.)

Jaune: Did you ever feel... weird when someone was around you? Like...every time?

Kung Jin: Jaune. I want to tell you one thing...

Jaune: What is it?

Kung Jin: When I saw you, my heart started beating like crazy...

Jaune: Me too, Jin... I guess... I guess...

Kung Jin/Jaune: I love you.

(Then they have a little kiss before the screen fades out.)
