In a place on the city, the Pj Masks were in a big mansion for their vacations...

Owlette: Wow! Look at this mansion!

Gecko: Do you like it Lionel?

Lionel: (nods)

Gecko: Hey! Where's Catboy?

Pj Robot: Beep beep (Right there)

And they saw Catboy with a box with a lot of CDs and DVDs

Owlette: Uh... Catboy... what is that?

Catboy: This are Death Battle videos that Cameron gave me

Owlette: Death Battle?

Gecko: Those are videos about characters fighting to death

Owlette: Woah...

???: That's interesting...

And then all villains appeared in front of them

Catboy: What are you guys doing here?!

Luna Girl: Nothing, we just heard about that Death Battle thing and we want to see it

Romeo: Yeah! I want to see it!

Gecko: There's a DVD in the living room, maybe we can watch it together

Wolfies: Cool!

Owlette: But don't cause any trouble, okay? Because we are going to bring guestes

Night Ninja: More people?!

Catboy: Good idea! Let's invite Batarina, Ladybug and Armadylan

Gecko: And the Paw Patrol

Owlette: And Vampirina

Catboy: And some other friends

Mothsuki: I want to watch them!

Owlette: Let's prepare everything to see the battles

Catboy: First... let's prepare ourselves

Luna Girl: We will wait for you right here

Catboy: Okay!

While the villains with Pj Robot were organizing the room, the PJs were starting to dress up to see the Death Battles

Romeo: Come on Pj Pests! Are you guys going to come out?!

Catboy:(behind the door) We're ready!

When they come out with their costumes, the others were surprised. Catboy was wearing Mario's hat with Sonic's sweater, Owlette was wearing Luigi's hat and Tails' sweater, and Gecko was wearing Yoshi's hoodie and Knuckles' gloves

Catboy: So... how do we look?

Kevin: You guys look cool!

Luna Girl: Yeah... but the lizard looks even better...

Gecko:(blushes) Uh... thanks...

DING DONG!

Catboy:(gasps) It must be the others!

When Catboy opened the door, he saw Vampirina, the other PJs, the Paw Patrol, Kit and Tesh, Sheriff Callie and her friends, Dash and Violet, Hiccup, Toothless, Light Fury, Astrid and the Big Hero 6

Catboy: Hey guys! Come in!

Batarina: Thanks for inviting us!

Gogo: This must be interesting

Vampirina: So... when is it going to start?

Catboy: Just in a moment... you should put something to watch the battles

Ryder: We will!

Catboy: The others can sit with the villains and my friends

Astrid: Uh... okay...

Fred: Are those villains plotting something?

Catboy: Actually no...

Dash: Come on! Let's watch the battles!

Vampirina: Wait! Me and the Paw Patrol need to change first

Kit: Me, Tesh and Callie too

Catboy: Okay! Take your time!

When they finally got changed, everyone was stunned of how they looked. Vampirina had a jacket of Shadow the Hedgehog with a black dress, Poppy was dressed in Amy Rose's dress in Sonic Boom, Bridget was dressed in Rosalina's dress, Ryder was wearing Mario's outfit, Katie was wearing Peach's dress, Kit was dressed in Tails' hoodie, Tesh was wearing Sonic's t-shirt, Callie was wearing Daisy's dress and the pups were wearing costumes; Chase as Sonic, Skye as Amy, Rocky as Tails, Zuma as Knuckles, Marshall as Shadow, Everest as Silver, Tuck and Ella as Mario and Luigi, Tracker as Yoshi and Rubble and Rex as Megaman and Porto Man

Owlette: Wow! You guys look awesome!
