(As Chalice had finished his speech, the rest of Class 1-A was merely focused on killing Henry and Arnold.)

Rikido: Now that those two are powerless, they won't be a bother for us anymore.

(Suddenly he gets blasted as the Ancient Rider Trio (Gabriel/Ancient Decade, Shiro/Ancient Kuuga and Hailey/Ancient Kivala) comes in, much to the people's shock.)

A. Zeronos: Who are you?

A. Decade: I'm just a passing-through Kamen Rider. Remember that!

Chalice: I don't care. If you're planning to save this rotten world, then I'll show you that nobody deserves to be saved!

A. Decade: (pulls out a card) Well, try this on then!

KAMEN RIDE: B-B-B-BUILD!

(Ancient Decade becomes Ancient Build.)

A. Zero-One: What? You can become other Ancient Riders?

A. Decade (Build): This and much more.

(Ancient Kuuga charges at Chalice as they have a clash.)

A. Kuuga: It's true we want to save this world ourselves. So tell us, why are you against this, and why do you want so trigger the apocalypse so badly?

(Chalice then decides to pull out a projector and turns it on as he shows everyone the discrimination among people regardless of whether they have superpowers or not.)

A. Kivala: What's the meaning of this?

Ojiro: Why don't you just let us kill those...

(Ancient Zeronos kicks Ojiro into the trees as Chalice decides to explain.)

Chalice: Human instinct is greed, the more they want something, the more they will get it and they will stop at nothing to get it. 

EVOLUTION!

(Chalice then becomes Wild Chalice.)

Chalice: That's why, all of humans must be destroyed... NO EXCEPTIONS!

(Chalice then kicks Ancient Kuuga before blocking Ancient Kivala's attacks and countering them and slashes her several times.)

WILD!

(Chalice fires a concentrated beam of energy at Ancient Kuuga and Ancient Kivala, easily defeating them.)

A. Decade (Build): Shiro, Hailey!

Chalice: You better concentrate on the game!

WILD!

A. Decade: (pulls out a card) Damn it!

FINAL ATTACK RIDE: B-B-B-BUILD!

(Ancient Decade (Build) tries to stop Chalice who fires the same beam at him, easily defeating him. Starlight and Black Noir appear along with Ozpin, who smirks by seeing Henry and Arnold powerless.)

Ozpin: It looks like we arrived in time to witness Henry Tennyson's death.

(Unfortunately for him, Salem and the League of Darkness come in as well.)

Salem: (glares at Ozpin) We meet again, Ozma!

Ozpin: What are you doing here, Salem?

(The Tennyson Family comes in as well as Ben, Ace and Ryan are transformed.)

Ben 10 (Rath): (glares at Chalice) LET ME TELL YOU SOMETHING, WHOEVER YOU ARE! GIVE MY COUSIN AND HIS FRIENDS THEIR POWERS BACK!

Chalice: (angry) You dare command me?

WILD!

Chalice: You will regret this!

Ultraman: Dodge!

(The Tennyson family dodges, except for Ben and Gwen who tried to block the attack, but it proves to be in vain as they get seriously injured.)

Ben: (reverts back) Ah crud...

Gwen: (grunts) You should at least have said "please", dweeb.

Ozpin: (to Chalice) You have impressive skills. Someone like you could be useful to our academy.

Mercury: You are kidding us, aren't you, old man? He didn't hesitate to fight heroes. It's obvious he would join our league instead!

(Chalice simply waves his hand.)

Chalice: No one can control me... (dashes at Ozpin and pierces his chest before crushing his heart.) no one!

(He seals Ozpin in a Rouze Card, creating the Albino Joker Card.)

Chalice: Since you're trapped into this card, Ozma. You won't be able able to reincarnate into anyone else anymore!

(Suddenly he sees Koharu Honda and sighs.)

Chalice: I didn't want to do this... but you humans left me NO OTHER CHOICE!

(He reluctantly uses his most based trick to immediately capture Koharu Honda as he makes another announcement.)

Chalice: Blame your supposed heroes for wasting YOUR chance to survival! Because now I will sacrifice this worthless girl's life and combine the sacrifice with the four Undead Category King Cards. Once it's done, I'll summon Jashin-14 to speed up the end of the world.

(Everyone's eyes widen as the Union Fake Heroes glare at Ben.)

Eijiro: YOU! YOU DOOMED US ALL!

Starlight: Eijiro! Calm the fuck down!

Shoto: CALM DOWN? HE KILLED ALL MIGHT, THE ACE OPERATIVES AND TSUKUNE! AND NOW OUR WORLD WILL SOON END AND THIS IS ALL HIS FAULT!

Emerald: (scoffs) Typical of fakers, blaming each other whenever bad things happen.

Ochako: SHUT UP, VILLAIN! DEKU-KUN AND OZPIN ARE DEAD BECAUSE OF THE TENNYSONS!

(Everyone keeps arguing as the screen fades out.)
