(A portal opens in Hatville, and a Kamen Rider comes out of it along with a couple of girls.)

????: This is the world where Kamen Rider Decade is.

????: What's so special about this world?

????: Knowing Tokuro, there might be some valuable things for him to take.

????: Can you blame him? He is a treasure hunter.

????: At least, he doesn't take things from people if it's important for them.

????: Well...

(Meanwhile Kamen Rider Decade is seen in a park, ready to face Breakdance.)

Decade: Henshin.

Decadriver: Kamen Ride: Amazon! (Gigi Armlet transformation sound)

Decade: I'll show you brutality.

(Then Breakdance tries to shoot Kamen Rider Decade down with his vibration shots, but Lincoln proves to be resistant and then hits the villain with various punches and kicks until he scratches his chest, causing him to collapse, and then he steps on his spine, breaking it.)

(Tokuro is seen eating in a restaurant along with his girls, but suddenly Johnny Bravo approaches one of them.)

J. Bravo: Hey, kitty.

(Tokuro sees Johnny Bravo trying to flirt with one of his girls, and then he punches him in the face before grabbing him in the collar)

Tokuro: Listen, filthy pervert. Don't let me catch ya hitting on my girls when I'm around. (glares) You understand? Now... BEAT IT!

(Then Tokuro throws Johnny Bravo into a trashcan, and then he shoots it, sending Johnny Bravo rolling in the streets.)

Tokuro: (scoffs) Loser...

(Cut to the bridge, Kamen Rider Decade is seen ready to face Extruded Man.)

Decade: Henshin!

Decadriver: Kamen Ride: 1 (Ichigō)! (Typhoon transformation sound)

Decade: Get ready!

(Then Extruded Man tries to hit him by stretching his arms, but Decade jumps off and then kicks him in the chest, sending him sprawling.)

(Back to Tokuro, he is seen as Kamen Rider Diend stealing a crown in a museum.)

Diend: Well, this is an interesting find.

(Cut to the pier, Kamen Rider Decade is seen in his Kabuto Form chasing after Johnny Quick, who stole something. Then Ben 10 comes in as XLR8, and both manage to catch him.)

(In Hatville, Power Ring is seen terrorizing people, but then he gets hit by Rigby, who is seen wearing a Death-Kwon-Do shorts, implying that the raccoon hit him with a Death Punch. Then Finn, Jake, Steven Universe and Mordecai come in.)

Power Ring: A bunch of kids wants to fight me? Ha! Don't make me laugh.

Rigby: Said the man who couldn't block my Death Punch.

Power Ring: (angry) Bad time to tick me off, raccoon.

(Then Jake stretches his legs and arms, and then Finn draws his sword and tries to attack Power Ring, who blocks him, and then shoves him off. Jake catches Finn while Steven Universe and Power Ring have a clash. Then Kamen Rider Decade comes in, and then he pulls out a card.)

Decade: Henshin!

Decadriver: Kamen Ride: Agito.

(Then Kamen Rider Decade becomes Kamen Rider Agito)

Decade: Time to handle this guy.

(Suddenly, Tokuro and his girls are seen watching them.)

Tokuro: There he is.

Octavia: Should we help them?

Velvet: Let's make a vote.

Molly: Who wants to...

Tokuro: We'll help them. (pulls a card) Henshin!

Diendriver: Kamen Ride: Diend!

(Tokuro becomes Kamen Rider Diend, and then he steps into the battleground.)

Power Ring: Who are you?

Diend: I'm just a passing-through Kamen Rider. Remember that.

Decade: Hey, that's my catchphrase.

Diend: Sorry. I tend to take treasures from other people. And your catchphrase is one of them. (pulls out two cards) But let's put that criminal in his place.

Diendriver: Kamen Ride: Shadow Moon!

(Then Shadow Moon is summoned)

Diendriver: Kamen Ride: G3!

(Kamen Rider G3 is summoned next)

Diend: Okay, let's go!

(Then Power Ring tries to hit the four Kamen Riders, but they aren't fazed by his attacks, and then Kamen Rider Diend pulls out a card and inserts it on his Diendriver)

Diendriver: Final Attack Ride: D-D-Diend!

(Nine rings of cards showing the previous nine Heisei Riders appear before Diend fires a green and black beam through them and into Power Ring, killing him.)

(Some hours later, Lincoln, Tokuro, Isaac, Edge and other heroes are seen in a kitchen.)

Tokuro: Hey, let me ask you, have you eaten sea cucumber yet?

Lincoln: Uh... no...

Mordecai: Me neither.

Tokuro: You will like it. One of my wives is excellent at cooking.

(Then Molly comes in with some Braided Sea Cucumber with Fish Maw.)

Molly: Dinner's ready, darling.

Tokuro: Okay, guys. Are you ready to eat it?

Ben: You know, this reminds me of my grandpa's cooking.

Tokuro: Come on, Tennyson. Try it.

(Ben eats some, and gets amazed by this.)

Ben: I admit, it's delicious.

Tokuro: Cooked by the best.

Molly: Oh, Tokuro.

(Molly kisses Tokuro's cheek, and then the heroes start eating as the screen fades out)
