Arche is now looking at the rooftop of the Great Tomb of Nazarick but was surprised there was the statue of Ohma Zi-O so massive that his whole body was seen.

Arche: The more I think about it, the stranger it is. I can't tell what era or setting what those ruins came from or that Statue as well...

Hekkeran: Then there's a high chance we'll stumble across into something interesting.

Imina: There's no mistake for that.

Roberdyck: Everyone, there is also a chance that a Terrifying Being lurks within.

Arche: But, I'm a bit excited.

Imina: True, I wonder why this person has created and what kind of person is buried under there.

Hekkeran: Right, it's always exciting to finding out about the unknown.

Arche: And it would make me happy if there's a lot of money inside.

Imina and Roberdyck laughed.

Arche: Huh? What? *embarassed blush*

Hekkeran: Yeah, I'm sure it will be our best job yet.

(Oh, you have no idea. It's to DIE for.)

The Kamen Riders has long been extinct. Since then, they were remembered as Legends by the people of the new world. Now, a Yggdrassil Player has taken a mantle of the Strongest, Kindest yet Evilest Overlord! IWAE! For a Legend will return! Ohma Zi-O!

Yeah~~ Oh~~

The Great Tomb of Nazarick's entrance is shown as all of the Floor Guardians appeared before a great beam of lava bursts out of the ground as Ohma Zi-O appears and the Japanese Letters came out and combined to the helmet making the visor.

Isshun de tsukamitoru no sa Are you ready?

The screen then shows Ohma Zi-O saw the 41 Supreme Beings, then the 20 Kamen Riders and looked behind with his visors glowed.

(Are you ready?)

Atarashī rekishi wa soko ni Feel it! Feel it!

Then it shows Naberal Gamma walking throwing her Pleaides Maid Uniform away and she is wearing her Nabe Costume before she transitioned into Kamen Rider Geiz with the Pleaides following her.

(Crazy Baby!)

Hikari wo kate ni kasokushite

The Blond Man appeared from the Epilogue of Season 2 stepping on Naberal's Maid Costume with the Old Man beside him as his army charged with the Blond Man having an evil smirk.

Konomama Shout it out! Shout it out!

The Floor Guardians making their appearance, Aura grinning and Mare smiling shyly, Cocyutus spinning his axe before standing straight, Shalltear bowing like a Proper Lady, Demiurge transforming into Kamen Rider Woz and Albedo looking at the screen with a blush and Yandere Face.

Ima wo susume yō

Brain, Climb, Gazef released their swords.

Madō hi mo Ikudo tonaku Asu no tobira tatake

Then it showed the family tree of King Ramposa III at the top, then Prince Barbro, Prince Zanac and Princess Renner with a Yandereish and Evil Face but it was shown by a book of an Unknown Man with a hood.

Mitsumeta sono saki ni

It shows the Pleaides showing their skills, Yuri practicing her punches, Lupusregina winking before unleashing her claws and scratches the screen, Naberal then uses Lightning, Solution's butt was shown and she giggled, CZ fires her guns, then Entoma then raises her insect hands.

Tobikonde mitara

Then it shows the Goblin Army smiling with Enri and Nphirea.

Believe yourself!

Then the Rusted statues of the 20 Kamen Riders crumbling down as they all posed.

Now, Over Quartzer!

Momonga taking the form of Tokiwa Sougo then transforms into Kamen Rider Zi-O and doing his pose.

Toki no ame Surinukete Tomo ni

Then it shows every Overlord Character were surprised as they saw the Froze of the Kamen Riders doing their Rider Kicks.

You, Over Quartzer!

At a very fast motion, Zi-O II appears first then poses, next is Grand Zi-O with the Emblems of all 20 Riders floating around him in a circle and Zi-O Ohma Form standing on a building with a Massive Statue of Ohma Zi-O behind him.

Mirai wo koe yō

Then it shows Geiz firing the Zikan Zaw in Bow Mode and swings it in Axe mode, before Geiz Revive appears, both in Gouretsu/Shippu Form in split screen, then lastly Geiz Majesty standing in the middle with the 19 Ridewatches of the Secondary Riders floating around her.

Kako no ishi wa Uso de wa azamuke nai

Then it shows Woz with White Woz's tablet, then Woz Shinobi Form doing handsigns, Woz Quiz Form showing up, Woz Kikai Form moving arms in a mechanical way with Electricity Emitting and lastly Woz Ginga Form holding a Universe in his hands.

Kanjiro sō Nexus Future

Then it shows Ohma Zi-O sitting on the throne with Albedo on his side as the Guardians bowed in their knees.

Now, Over "Quartzer"

Then it shows a Deserted Background with Destroyed Cities as Zi-O came face to face with Ohma Zi-O.

Mabayui sekai

Then both of them charged and swings their fist against each other.

Misete

The Title: Kamen Rider X Overlord: The Reign of Zi-O logo appeared.

Nighttime appears as the Workers are planning everything out while looking at the Great Tomb of Nazarick with the Ohma Zi-O Statue much taller than the Tomb itself.

Hekkeran: Once all of the teams have reached their positions, we will start simultaneously at the signal. We will enter four different points, explore each small mausoleum, then meet up at the Central Mausoleum.

Gringham: Yes.

Erya: No problem.

Papatra: Understood.

They entered via Invisibility as they sneaked in to the entrance as they turned visible again.

Gringham's Knight: The effect of Invisibility barely lasted.

Gringham: It lasted long enough. Let's go.

They entered as the Knight then released his sword for possible enemies.

Gringham: There's seem to be no traps.

The Magic Caster of the Team then uses a spell.

Gringham's Caster: CONTINUAL LIGHT.

His large wand glowed including the warrior's sword as they saw to be the Gravestone of Kamen Rider Kuuga.

(Yes, from Kamen Rider Heisei Generations Forever.)

Even there are lots of statues involving Kuuga's All Forms, and in the center is Ultimate Kuuga. And the Emblem of Kuuga is on it's chest.

Gringham: Hm, it looks to be a Legendary Warrior. Does anyone have a knowledge of the crest on that statue?

Gringham's Knight: No, I do not know of it. Is it a possibly a crest existed before a Kingdom?

Priest: By the way, Leader, stop talking like that.

Knight: We're the only one's here now.

Gringham: Yes... Man, I'm so exhausted. Talking like a hardass like that, I feel so stupid.

Knight: Thanks for the hard work. It's fine if you talk like normal like rest of us.

Gringham: Nah, I can't do that. That kind of formal talk makes us look like. more talented workers. It's a pain to switch back and forth. You know that talking like that is my policy that we're in a middle of a job.

They chuckled.

Gringham: Now then, let's move forward.

Gringham's Team: Right!

As they were examining everything of Kuuga's Mausoleum.

Caster: This Statue is made that was built to last. This might be the gravestone of a Legendary Warrior that might existed a long time ago.

Assassin: Really, what is that name of that Warrior?

Gringham: I think there's a writing here and luckily we can read it.

Knight: Okay, I'll do it. *clears throat* "Here lies the Warrior of 2000 Skills, Protector of Smiles, The Ancient Warrior existed for Millions of Years; and the First Heisei Rider, Kamen Rider Kuuga."

Gringham: Kuuga huh? Where did I heard that name before?

Caster: You wouldn't. This means that we are in the Tomb of the Legendary Kamen Riders!

Knight: No way! It exists?!

Gringham: And we're here. We discovered it. Now time to open that Coffin.

They nodded as they tried to open Kuuga's Coffin as they opened and they saw the Previous User of Kuuga with the Arcle Belt untouched by time and age but the user. was decayed to the point it was left in bones.

Gringham: The Kuuga Arcle. The Belt that can transform you to Kamen Rider Kuuga.

Knight: Shall we take it?

Gringham: No, leave it. We got what we came for. We don't want to keep the others waiting.

They nodded as they ran out as the scene changed to the Main Entrance of the Great Tomb of Nazarick as the Foresight Team then saw Gringham.

Hekkeran: Took you long enough.

Gringham: Sorry to keep you all waiting.

Hekkeran: We didn't decide tbe rendezvous time, so no worries.

Gringham: I wish to ask, did yoh. uncover treasures or coffins?

Hekkeran: We found the Mausoleum named Kamen Rider W. According to legends he is known as the Two-in-One Rider, combining the Body and Soul of two beings into one being as well as the holder of all of information in the world.

Gringham: We found the Mausoleum of Kamen Rider Kuuga. It seems that the Tomb is dedicated to the Legendary Riders that were in the books!

Hekkeran: Elder Papatra discovered the Mauloseum of Decade, also known as the Holder of 20 Kamen Rider Powers and Destroyer of Worlds. And Erya discovered the Mauloseum of Kamen Rider Build, the Genius Rider who invented Science in this world.

Gringham: Sounds like you guys are having a good time.

Hekkeran: So this is the point where all the teams start exploring the lower floors but...

They were the First Floor of Nazarick guarded by Shalltear Bloodfallen, one of the Strongest NPCs that matches Grand Zi-O in power, as they saw lots of corpses of those who entered before.

Gringham: The stench of the dead...

Hekkeran: Yeah, that's right. It's the same smell that often fills our nostrils at the Katze Plains.

Papatra: I have a proposal for all of you.

The Foresight and Gringham's Team stepped down as they saw Papatra and Erya's Team.

Papatra: My team and I will back out and look for any secret entrances.

Papatra's Team were surprised by this.

Papatra: There is a chance that there are other routes inside.

Gringham: The Elder speaks the truth. There may be an another route that will lead us safely to the center of the Tomb.

Papatra: So in exchange for taking a loss, I'd like to share about your discoveries. Let's see. About 10% each team. Also, will you give us first chance at the lower floor tomorrow if a route is found?

Gringham: We have no qualms.

Hekkeran: Us, too.

Erya: Personally, I have some objections. 10% is not a problem. However...

Papatran: Alright, it's decided then!

He growled as hebwas ignored as Papatran's Team goes out of the Tomb.

Papatran: Be careful down there. Though, if you find valuables, we wouldn't mind if you let them for us.

Erya: Tch!

Hekkeran: Well, let's head down.

Roberdyck and another Heavy Hitter opens the door revealing a Green/Violet Hallway.

CYCLONE/JOKER!

Hekkeran: Well, that's a surprise.

Imina: Rober, is there an undead response from that corpse?

Roberdyck: No, there is not.

Arche: I see.

Black Knight: This Tomb is really a mystery.

Priest: The Place can be more than 600-1000 years old.

Arche: If so, this is truly a historical find.

Erya: Can we hurry up? Personally, I want to hurry up and hunt down some monsters.

They saw movement as the Workers blinked and surprised.

Hekkeran: There's no way.

Archer: Are those Humans?!

Man: Leave the Tombs or Die!

MASQUERADE!

Thousands of them are transformed into Masquarade Humans and charged forward.

Gringham: WHAT IS THAT?!

Roberdyck: DOPANTS! THE ENEMIES OF KAMEN RIDER W, USING THE CORRUPTED GAIA MEMORIES, ITEMS THAT HOLDS A MEMORY OF A ORGANIC OR INORGANIC BEING OR OBJECT!

Erya: So basically they have been claimed by Hell itself.

Imina: Oi, oi! Who's going to fight them first?

Gringham: Damn, even though they're humans, we have no choice. I'll be first!

Hekkeran: MATTE! THEY'RE GOING TOO F--

He was kneed in the face by a Masquarade Dopant as the rest of them were attacked and surrounded by them.

Gringham: DON'T MESS WITH US!

He then slices all of their heads off as blood splatters and they fell down, dead.

Gringham: Don't give up yet! Those might be weak, but as soon as we go deeper and deeper, we might be able to encounter strong enemies! Move forth!

The scene then changes to Zi-O and Geiz.

Zi-O: So they truly entered, huh?

Adventurer: Yes they did. Even though they are workers, they are our comrades of this job. I hope that they can come back safely. What do you think, Zi-O-san?

Zi-O: They all die, won't they?

Adventurer: Eh?

Zi-O: N-No! I mean that they should have that kind of resolve. These ruins are a new discovery. There could be all kinds of dangers.A foolish hope will just leave you hurt.

Adventurer: I see. That's what you meant. Thank you for worrying about me.

Zi-O: Then, as planned, I will rest first.

Adventurer: Yes, please take your time.

He goes back to the Tent they are in as Geiz was waiting for him.

Zi-O: Now, Nabe. No, Naberal. I shall return to Nazarick. Is the Weapon ready?

Naberal: Yes.

Zi-O: Then Pandora's Actor shall take my place. Make sure to handle things as anything happens.

Geiz: Understood, Lord Zi-O.

He turns to Ohma Zi-O.

Ohma Zi-O: Then, I will leave it to you. And time to put this weapon to use.

He opens a large box revealing a Certain Golden Gauntlet. He puts it on his left hand.

Ohma Zi-O: I'll be back.

Geiz: I understand.

He disappears as he appears to the doors of the Main Room as it opens revealing to be Albedo bowing to her knee.

Albedo: Welcome back, Lord Zi-O. And that Gauntlet...

Ohma Zi-O: I'm home, Albedo. We have intruders. They are now entering, as planned. How are the welcome preparations?

He walks forward as Albedo follows him.

Albedo: We are fully prepared. I am sure that our guest will enjoy in what we have in store.

Ohma Zi-O: I look forward to the results of your hospitality.

He sat down on his grave. Albedo then summons a futuristic keyboards and types.

Albedo: Please look at these screens.

The screens show three teams splitting up.

Ohma Zi-O: Tch! It looks like they have finally entered to their doom. Albedo, do not let a single one go home unscatched. Leave no survivors.

Albedo: Of course, Waga Maoh. Please watch as the fate of the Foolish Thieves they have entered abode of the Legendary Kamen Riders and the Venerable Supreme Beings. Also, which group would you use to test the Guinea Pigs of the Infinity Gauntlet?

Ohma Zi-O: Ah yes.

Kamen Rider Ginga, Gold Drive, Evol, OOO Putotrya Form, Chronos, and Extremer arrived and bowed.

Ohma Zi-O: I have need for all of you. Let's show them the true meaning of fear.

The Foresight Team are heading forward.

Hekkeran: Now that was freaky. I mean humans that can transform into Monsters willingly? That was scary as heck!

Arche: What creeps me out more that this is only the First Floor. Meaning we only face the easiest monsters.

Imina: Shhh!

They turned off the light as they go to the corner and saw more Masquerade Dopants lining up. With Bows, and Swords on their hands.

Hekkeran: How troublesome...

Arche's eyes glowed.

Arche: Those two in the center are using Magic. First Tier, in fact. It will be bothersome if they shoot magic from here.

Hekkeran: I wonder if bows are ineffective against them?

Roberdyck: They did survive punches and kicks of a Kamen Rider, stronger than that of a Human, even with fully trained and experience warriors. Let me take care of it.

He stepped forward in all of them.

Roberdyck: TURN UNDEAD!

A bright light appears blinding them from the light as they shouted in pain.

Hekkeran: Damn! We need to kill them while blinded!

They nodded as they finished all of them off in record time.

Hekkeran: Alright, let's go!

Back to Papatra's team leaving the Tomb.

Papatra Member: Elder, that was such a waste!

Papatra: We received priority for tomorrow. It is not complete loss for us. To begin with, it is a bit too dangerous to be the first to enter an unknown dungeon. They are our canary.

Yuri: A level handed decision.

They looked behind revealing the Pleaides except for Naberal Gamma.

Papatra: Who are you all?

Blond Man Member: What shall we do?

Papatra: Same number on both sides. We may be able to manage.

Hooded Member: But Maids on a Tomb. That's a bad taste.

They gritted their teeth as they were surprised by the killing intent as the Hooded Member looked at them confused.

Entoma: Let us kill them.

CZ: We shall kill them.

Solution: We should not just kill them, but do it in a way that is indescribely painful.

Yuri: Hai hai! We were planning to kill them from the start. Though, I'm happy that everyone is motivated now.

She has the Gashat Gear Dual Gashat.

The Papatra Team stepped back.

Yuri: Now, due to some certain circumstances, we cannot murder you, directly. It is unfortunate.

CZ has a Grey Ziku Driver on her chest which is the Mirai Driver and the Golden Wrench and Screwdriver.

Solution has the Neo Amazon Driver.

Lupusregina has the Ziku Driver and the Zamonas Ridewatch.

Entoma however, has none but has a monstrous form inside her.

Yuri: But, even if we would like to use this, I would like to introduce you to your opponent. *claps her hands* Come, Kamen Riders!

Papatra: What?!

The Six Kamen Riders that appeared earlier in the Throne Room has arrived as Papatra's Members looked behind.

GIN-GIN-GIRA-GIRA GALAXY! UCHU NO KANATA NO FANTASY!
KAMEN RIDER GINGA!

Kamen Rider Ginga then released his Universal Powers.

Ginga: Everything will come to perish. As all of you, will perish. That is the law of the Universe.

Kamen Rider Gold Drive then laughs insanely.

Gold Drive: May I demonstrate that I have an intellect that surpasses yours?!

COBRA! COBRA! EVOL COBRA!
HAHAHAHAHAHAHAHA!

Evol: COME ENTERTAIN ME, HUMANS! OR ELSE I'LL DESTROY ALL OF YOU BEFORE YOU KNOW IT!

PTERA! TRICERA! TYRANNO!
PUTOTYRANNOSAURUS!

OOO Putotyra Combo then roared out loud as Ice Mist comes out of OOO and his visors glowed green.

DASH THROUGH THE HEAVENS, KAMEN RIDER! ENGRAVE THE CHRONICLE! NOW TIME IS IN YOUR HANDS!

Chronos: I, hereby declare you all, discontinued.

Kamen Rider Extreme then released his Golden Flame Aura and Black Smoke.

Extremer: Now then, I'll kill you nice and easy. As the powers of the Legendary 100 Souls are within me!

Papatra: An unexpected attack. And their power is colossal... Additionally, they don't have the means to fight.

The Six Riders walked forward as they released and bursted power from their auras as the Papatra Members gulped.

Papatra: Magic?! No. It wasn't magic. But rather pure power?

Evol: Guys, guys, guys! How about we finished them all off in one attack?

Extremer: Fine. Our Lord is waiting for us anyway.

The Pleaides then creates a massive indestructive barrier at all sides protecting the Great Tomb.

Lupusregina: Ooh, that's bad.

CZ: I did not expect them to be this bad.

Solution: They are gonna die anyway.

Entoma: What a waste. I was gonna eat their corpses but oh well.

Yuri: Yes, indeed.

GIGANTIC GINGA!

Ginga then focuses on the power of the Universe on both of his hands as he created a massive Blue Star smaller than that of the Moon and throws it at one enemy as he screamed the Star exploded.

FULL THROTTLE! (In Banno's Voice)

The Golden Tridoron appears and spins around creating a barrier as Gold Drive then jumps and kicks the enemy at all sides nearly as fast as Mach 1. Until the Last Kick goes through the enemy, he screamed and exploded.

SCANNING CHARGE!

OOO then unleashes Pteranodon Wings and freezes the enemy, like Sub-Zero, before he grew out a Violet T-Rex Tail as tail swings at the enemy shattering it at one attack.

CRITICAL CREWS-AID!

Chronos stopped time as Extremer somehow moved in stopped time and absorbs the 4th Member's Soul as Chronos then 360° roundhouse kicks the 4th Member.

THE END OF THE LINE!

The 4th Member explodes leaving Papatra the only member.

Papatra: NO! HOW COULD THIS HAPPEN?!

Evol: Ciao!

READY GO!

He then jumps up and frontflips.

EVOLTECH FINISH!

Evol then Rider Kicks Papatra as he was sent above the sky before he explodes.

CIAO~!

Evol: As I expected, they were weak.

Yuri: Since they are all dead, we shall report this to Lord Zi-O. Riders, return to him.

The Six Riders nodded and disappeared. As the Gringham's Members ran away as Fire then lights up the walls.

Knight: SHIT!

It revealed to be Graphite in Level 99 Form.

Graphite: COME BACK HERE! I'M NOT DONE WITH YOU!

Knight: THERE'S NO WAY WE CAN BEAT THAT!

Caster: THE BLESSINGS OF GOD CAN ONLY TAKE US THIS FAR!

They keep running as Graphite fires more Dragon Breath as he kept chasing them.

Gringham: ARE THEY STILL CHASING US?!

Knight: YES! THEY ARE STILL AFTER US!

Archer: RUN, BITCH! RUN!!!!!

Graphite then still chases them as Archer then finds a door.

Archer: HEY! A DOOR!

He opens the door as they go inside and immediately closes it and barricades the door. But it was too dark.

Gringham: Anyone here?

Knight: Here, Gringham.

They all said here until they heard this...

DANGER!

Gringham: WHAT WAS THAT?!

Archer: I DON'T KNOW!

Knight: WE'RE GONNA DIE!

Caster: FUCK! FUCK!

Gringham: WHAT WAS THAT SOUN--

Then everyone saw Kamen Rider Rogue and his visors glowes from the Darkness.

(Little Girl Scream Sound Effect)

Gringham and his Team: AAAAAAAAAHHHHHHHHHHHHHH!!!

CRACK UP FINISH!

The scene changes back to the door outside as screams were heard from the door, explosions, splattered sounds, and lights coming out from the bottom of the door.

The scene then changes to Erya's Team as one of his Female Members stopped.

Erya: Why have you stopped? Keep going.

Female Elf: Ah! Um, I can hear something!

Erya: Hear something?

Clashing of metal was heard as the Erya Team stepped forward and they stepped back in fear as they saw the Amazons Rider.

Erya: WHAT THE F**K?!

Alpha: Yo, fresh meat. Time to feast.

Erya: I'm the Meat huh? Don't underestimate me.

Hamsuke: YOU CAN DO IT, ALPHA-SAN!

Erya then released his Katana as Alpha gets on his Fighting Stance.

Alpha: Here I come!

He charges forward roaring.

Erya: MARTIAL ART! SHUKUCHI KAI!

As time slows down he dodges Amazon's swing claws and then, Erya swings his sword but Alpha stomps the ground and shoulder charges Erya's stomach which he was sent on a great distance making him roll over the ground. Erya growled as his eyes widened as a drop of blood falls down his nose and he wipes it.

Erya: YOU SHITTY BASTARD! MARTIAL ART! ABILITY BOOST! GREATER ABILITY BOOST!

Alpha: Oi, oi! If you keep doing that, you might get attacked when you least expect it. But since there's only one of us here... and those guys...

The Amazon Riders cheered, even the Warrior Lizard Men and the Death Knight.

Amazon: Come on, show me what you got.

He walks forward towards Erya.

Erya: DON'T UNDERESTIMATE ME, MONSTER!

He then tries to stab Alpha visor but he blocks it with his arm but he pushes his sword as Amazon Alpha tilts his head to dodge it.

Alpha: Tch!

He then backflip kicks Erya but he blocked it by his Katana but due to the force of the Kick he was sent away as he lands down and skids. He smirks but he saw an Amazon Knife then impaling his neck as chokes in pain and he falls down holding his neck as it impales through his throat and tries to removed it.

Alpha: You should have checked your blind spots.

He tries to speak but can't.

Alpha: Oh, poor baby? Can't even speak? Do you need mama to spell it out for you? Well, for what am I gonna do to you, you're gonna die.

VIOLENT SLASH!

Alpha then grabs and lifts Erya by the neck before he PUNCHES THROUGH HIS STOMACH AS GUTS AND ORGANS FLIED TO THE WALL! Erya's female members gasped and puked before he sliced upwards to his head, slicing his body in half, just like he did with Neo Alpha!

Neo Alpha: Deja Vu...

Alpha: FRESH MEAT!

He then proceeds to eat Erya's corpse as the Female Members whimpered and wet their panties by the sight.

Zaryusu: Damn...

Hamsuke: Now I'm jealous and understood why I didn't fight. Because Alpha-sama makes it quick, so he has.

The Three Elves then just laughed insanely and kicks Erya's Corpse.

Alpha: I LIKE THESE LADIES! HEY, WOULD YOU MIND, I CAN KEEP EM ALL! 

Neo: OI, TOU-SAN! YOU'RE TECHNICALLY CHEATING ON MOM! Then again, you tried to kill both of us, so...

Sigma: One heck of a family you have, Neo.

Omega: I pity you, Chihiro.

Neo: You don't need to. *sighs*

Back to the Foresight Team.

Imina: Where are we? As I thought, that thing was a magic trap.

Everything is dark.

Hekkeran: Well, after the ground below, our feet lit up, we ended up here. This area looks very different from the others...

Arche: I have seen a place similar like this...

In front of them was the Entrance to the 6th Floor of Nazarick, the Colosseum, guarded by Aura Bella Fiore, and Mare Bella Fiore.

Arche: The Colosseum of the Empire.

Roberdyck: Now that you mention it... Then the arena is just ahead.

Hekkeran: Seems so. Since we were teleported here, there can be only one thing...

In the shadows, the Infinity Gauntlet was shown as the Six Riders, Ginga, Gold Drive, Evol, OOO, Chronos, and Extremer turned into the Six Infinity Stones as they combined with the Gauntlet as Blood Red eyes was shown.

???: Dread It... Run From It... Destiny Arrives the Same... Or should I say... I AM.
