(At Titans Tower, Red Beast Boy is seen opening the door as various girls are seen)

????: Hello...

Red Beast Boy: (blushes) Hi...

????: (giggles) You're cute.

(She pecks on his cheek)

????: We heard that the Igawa sisters are here and we wanted to pay them a visit.

(Then Asagi and Sakura come in)

Asagi: Kousaka. Mizuki.

Kousaka: There you are.

Sakura: What are you all doing here?

????: It's good to see you're alright. But we need your help.

????: Ingrid, one of the Hellish Knights, and the mercenary named Deathstroke joined forces.

????: The reason why she allied herself with him we don't know.

(Then some beeps are heard)

Red Beast Boy: Uh-Oh. It looks like they are already making their move.

(Then the Titans come in)

????: You must be Asagi's friends.

????: You will not believe this, but...

Cyborg: Slade is up to his old tricks. And it looks like that hellish knight was with him lately.

(Somewhere in the docks)

Deathstroke: I'm honored to have your help, Ingrid.

Ingrid: What do you want, Slade?

Deathstroke: I need some help to destroy Nightwing and the Titans. And you already know that your enemies joined them.

Ingrid: And what do I gain with this?

Deathstroke: Is there something you want in exchange?

Ingrid: Yes. One of the Titans. The Red Beast Boy. I want him. And if you spare him, I will give you a considerable amount of money.

Deathstroke: OK. We have a deal!

Ingrid: When will we begin?

Deathstroke: First, I got to free an old friend of mine from Stryker Island.

(Some hours later)

Robin: It looks like Slade is planning an invasion on Stryker Island.

Nightwing: Okay, team. We need a plan to stop him. We know that Ingrid will somehow try to prevent us from stopping Slade. Then while the Taimanins handle her, the Titans will try to stop Slade.

Static: Sounds like a good plan.

Kousaka: Okay. Let's do this.

(At Stryker Island, Deathstroke is seen fighting The Flash)

The Flash: Somebody here didn't learn the lesson!

(Deathstroke tries to shoot The Flash, but the speedster easily avoids the shots until he shoots the locking system, setting the other villains free, including Jinx and Terra. As the Titans arrive, Superboy communicates with Superman)

Superboy: Superman. You will not believe this, but...

(Superman is seen flying towards Stryker Island)

Superman: Deathstroke invaded Stryker Island. The Flash was fighting him when he broke the other criminals out.

(Back to Stryker Island)

The Flash: Uh-Oh.

(Then Kid Flash comes in, hitting Parasite while Static fights Livewire, Starfire shoots down Icicle Jr, Raven clashes with Grodd and Aqualad faces Volcana. As Beast Boy comes in, he is pinned by Tara Markov, then kissed by her)

Beast Boy: Tara...

Terra (Tara Markov): I'm sorry...

Beast Boy: For what?

Terra (Tara Markov): For this...

(Terra knocks Beast Boy out and prepares to take him away)

Terra (Tara Markov): And this time, I'll make sure they don't find us!

(Deathstroke tries to hit The Flash again, but the speedster avoids each attack of his)

The Flash: I'm here, big guy!

(Deathstroke draws his sword and tries to attack him, but the speedster grabs his wrist and throws him to Nightwing and Robin who knock him out with a double kick)

Nightwing: Good job, Robin!

Robin: Thanks to Flash!

(The Flash gives a thumbs up)

(Meanwhile, the Taimanins were trying to attack Ingrid who holds her own against them. Seeing this, Red Beast Boy morphs into a gorilla, only for Ingrid to notice that and manage to knock him out with a karate chop, then she takes him away)

Taimanins: JACK!!

(Then the Justice League comes in)

Superman: What happened here?

Asagi: Ingrid took Red Beast Boy away.

(Starfire comes in)

Starfire: Beast Boy was taken away too.

(Nightwing comes in, dragging Deathstroke)

Nightwing: It looks like she left Slade behind.

Batman: I'll take Deathstroke back to Arkham. The rest will help the Titans and the Flash.

(After an epic fight inside the prison, the villains were taken back to their cells. But both Beast Boys have been kidnapped. Will our heroes rescue them?)
