(After their second defeat at the hands of their ex and his friends, the girls who cheated on Nate became even more hated at school, and even the principal expelled them for having become villains.)

Principal: If you have someone to blame for your reputation being ruined, it's yourselves. You disgusting bitchy criminals!

(Making things worse for them, many sites have performed a Thot Patrol Club which classified both the girls and Yor as thots. Speaking of Yor, she got fired from her job, and rejected from any other job. She eventually made a deal with a devil which possessed her.)

(Back at LexCorp, Lex Luthor sees both drivers and Zetsumerisekeys complete.)

Luthor: Took you long enough.

(Luthor then clicks a button as the girls and Devil Yor come in.)

Luthor: You must know why I called you here.

Takagi: You built a weapon for us to avenge Victor?

Luthor: As much as I wanted to say he deserved to die for failing me so miserably... yes.

(Then he gives the four MetsubouJinrai Drivers to Marin, Nagato, Takagi and Komi.)

Luthor: This will connect you four into only one body. Oh, I forgot to give you these.

(Luthor gives them the Massbrain Zetsumerisekeys.)

Luthor: But I must warn you. Once you combine into one, there will be no coming back.

Nagatoro: We don't care. The Justice League took everything from us. We just want to return them the favor.

Luthor: (sighs) You've been warned.

(Luthor walks away as Uzaki, Anjou and Micchon got confused by what Luthor said.)

(Cut to Atlantis, Noah, Kaira and the Sword of Logos are seen at the throne room, where Aquaman comes in. Suddenly he sees two unwanted guests.)

Aquaman: Watch out, guys!

(The heroes turn to see Black Manta and Ocean Master.)

Nathaniel: Black Manta?

Aqualad: Ocean Master?

O. Master/B. Manta: In the flesh!

(Then Nathaniel and Tadano prepare to transform)

BRAVE DRAGON!

(They then insert the Wonder Ride Books in their drivers.)

Nathaniel/Tadano: Henshin!

REKKA BATTOU! KISEKI NO SAIYUU DRAGON! REKKA NISATSU! MUKKIMUKI NO OSARU NO KUWAWARI, KAEN NO TSURUGI GA MAI ODORU!

KAGAYAKU LION FANTASISTA~! NAGARE NISATSU! GAO! KIRAKIRA! GENSO NO TSUME GA IMA SOKI KENSHI NO SONOMI NI YADORU!

Saber: I will decide this story's ending.

Blades: I swear on Suiseiken Nagare that I shall protect.... the people that I love!

(They prepare to fight both Ocean Master and Black Manta. Saber's sword clashes with Ocean Master's trident, and he pushes the villain away before slashing him. Blades doesn't have the same luck, and is overwhelmed by Black Manta. Naoto then steps up and prepares to transform.)

NEEDLE HEDGEHOG!

LAMP DO ALAGINA!

IKAZUCHI BATTOU!

Naoto: Henshin!

TOGE! TOGE! LAMP DO HEDGEHOG! IKAZUCHI NISATSU! KYUKYUTTO KOSURU TO ARAWARETA SONO MAJIN E NO NEGAI TO WA CHIKUCHIKU NO YOROIDATTA!

Espada: My feelings will pierce through.

(Espada charges at Black Manta as he goes to help Blades. As for the other heroes, they are about to leave as they suddenly see more unwanted guests.)

Nishikata: (stern) You never learn, do you?

Najimi: Your arrogance will lead you to your own downfall!

(Marin, Nagatoro, Takagi and Komi place the MetsubouJinrai Drivers in their waists.)

METSUBOUJINRAI DRIVER!

AUTHORISE!

(Then they pull out their Zetsumerisekeys.)

MASS BRAIN!

M/N/T/K: Henshin!

PROGRISE! CONNECTION! (CONNECTION!) COMPLETE! METSUBOUJINRAI! QUARTET WITH UNIFIED WILL!

(The four girls combine into Kamen Rider MetsubouJinrai.)

MetsubouJinrai: We will destroy you all!

(The heroes get shocked by how low the four girls got, and then the screen fades out.)
