(Barry is seen talking with Oliver Queen through a communicator.)

Oliver: Barry, things are getting ugly here. Our planet is being invaded, by robots.

Barry: Robots?

Oliver: At first, Cisco, Caitlin and I thought it was Brainiac, but the robots seem to be holding weapons.

Barry: I'm on my way!

(Then Barry Allen gets out of his house and becomes The Flash.)

The Flash: (communicates) Where are you, Oliver?

Green Arrow: We are at Times Square, New York.

The Flash: Got it. I'm on my way. Over.

(As The Flash is about to arrive at Times Square, a figure similar to him chases after him, making him stop. The figure is none other than his archenemy Reverse Flash.)

Reverse Flash: Hello, Barry.

The Flash: Thawne...

Reverse Flash: I like what's happening to this place.

The Flash: So you're involved in this, huh?

(Then it was The Flash's turn to chase after Reverse Flash.)

Reverse Flash: Everything worked so well. That's why I let Oliver talk to you, you know. I thought you'd come.

(Then they stop at London, which is under attack of the White Fang.)

Reverse Flash: Not that you wouldn't ever come back to action, you... hero!

(They fight. Despite being evenly matched in every aspect, Reverse Flash still had some tricks on his sleeves and planned to use them against The Flash. But Barry somehow predicted them and after a long fight, he defeats his archenemy.)

The Flash: This is for my mom!

(Then The Flash decides to take down all of the White Fang soldiers, one by one.)

The Flash: Now to help my friends.

(Unfortunatelly, various microbots surround The Flash, forming a sphere. But thanks to his speed, he vibrates enough to go through the microbots, then he turns around and sees Yokai and Raynare.)

The Flash: Helping the invaders, huh? You're making a mistake!

(Raynare tries to throws some energy spears, but The Flash evades her attacks. Yokai tries his best by manipulating microbots. But The Flash evades his attacks too. They combine their attacks, but The Flash manages to get behind them and slam their faces each other.)

The Flash: Man, that was too easy.

(Then The Flash runs and finally arrives Times Square. But he notices that Green Arrow, Killer Frost and Vibe have been captured.)

The Flash: Damn it, I'm too late!

(The Flash quickly frees his friends while defeating the Atlas Soldiers. But then a raven comes in, turns into a woman and attacks The Flash.)

The Flash: Another enemy?

Raven: My name is Raven Branwen. And your friends are my tribe's prisoners now!

The Flash: Who decided that?

Raven: I decided.

The Flash: You will not take them away!

(They fight. Despite being not experienced against swordsmen, The Flash didn't need much to stop the leader of the Branwen Tribe. He decides to use his same old tactics which proved to be very effective as he manages to knock her out.)

The Flash: This will hold you for a while.

(Then Silver Sable comes in)

Silver Sable: You look different, Thawne.

The Flash: You're talking with the wrong speedster.

Silver Sable: So you're one of the so-called heroes, huh?

The Flash: The Flash, the fastest man alive!

Silver Sable: You're dead!

(They fight. Silver Sable uses her teleportation to evade The Flash's attacks. Knowing this, The Flash tries a new trick. He throws some rocks at SIlver Sable. She tries to shoot them, but The Flash throws the stones very fast, damaging her badly, then the speedster knocks her out.)

The Flash: Invasion, villains backing it up... not a big surprise.

(Then Vibe, Green Arrow and Killer Frost approach Raven Branwen, but then Team RWBY comes in.)

Yang: Don't hurt her.

(Then Yang checks her and notices she's still breathing.)

Yang: She's still breathing. Good.

(One minute later, Raven Branwen is seen at the hideout as she wakes up.)

Raven: Uh... what happened?

(To be continued.)
