(Various Super Sentai and Kamen Riders were known for saving the world from various threats, but some of them came from a world known as Union-Verse, where heroes simply do their jobs for fame, money, power, domination, destruction and others. Most of them were saved while others got destroyed. But now they will end up in a different Union-Verse.)

(Meanwhile at Union-Verse (Earth-1820), some cities are seen in situations of poverty and misery, especially those which were once great cities, while others like Atlas, Vale, Musutafu, Kuoh, Metropolis, New York, Tokyo and other few cities are in prosperity because the Union "Heroes" simply direct their help only at them, not caring about the rest of the world.)

(Inside of Union Academy, various students are seen celebrating something until a message is heard.)

????: Greetings, Union Academy.

(The students and staff of Union Academy are seen watching the figure who just showed up on-screen.)

????: My name is Lone Ivory, and these are my fellow generals.

(Two of Lone Ivory's generals appear on-screen.)

???? 2: My name is Teivel!

???? 3: And mine is Mercury.

Teivel: We came from a world far from yours. A world which suffered a fate worse than destruction because of you supposed heroes!

Mercury: We have traveled around an ocean of universes to reach you pricks.

(Then two other Generals are shown at screen as well.)

Jabez: For some time, some of your worlds sheltered some of the true heroes, like Super Sentai or Kamen Riders.

Damion: And we know they will come after us.

(Then Lone Ivory appears again.)

Lone Ivory: We'll be waiting for them. Until then, we'll be sending some toys for you to have fun with.

(Then some Shock Beasts are unleashed upon Union City as they start terrorizing the city.)

Lone Ivory: Let the games... begin!

(Lone Ivory laughs evilly as the screen becomes static, leaving the Union Heroes shocked.)

Ruby: Why would someone want do do this?

Iida: Ruby, they're villains. That's what they do.

Yang: Four-Eyed Sonic is right, sis. We'll take them down, and we'll do it with a "Yang"!

(Everyone groans at her puns as Levi stands up.)

Levi: Let's just go already!

(The Union "Heroes" go to face the Shock Beasts.)

(Meanwhile in another town, some groups of Super Sentai and a group of Kamen Riders show up.)

AkaNinger: Where are we?

AoNinger: Is this... Union-Verse?

ShiroNinger: Please, tell me this isn't happening.

Ichigo: Yeah, it looks like we're in another Union-Verse.

Nigo: Not different from ours, I see.

Zi-O: Union-Verse?

Ex-Aid: I'm glad my Winter Schnee isn't like those versions of her.

Red Buster: Something tells me we're about to fight the biggest battle of our lives.

Zolda: I can't wait to kick my brother's ass. Seriously, what's the difference between Union-Verse and Deku-Verse?

G: I would like to know as well.

Den-O: Ikuze, Ikuze, Ikuze!

(This is only the beginning.)
