Disclaimer: I on my Oc's.

"Hey, Orb! Are you alright?" asked Zero.

"Yeah, I'm alright, Zero," Orb reassured his predecessor.

"Good thing, we stopped those freaks. Otherwise, you'll be dead," said Gokai Red, while panting heavily due to fighting many Kaijins along the way. The rest of his team is supporting their other allies.

"I agreed." said Decade, who is also panting heavily."So, what are we going to do now?"

The three heroes looked at him.

"I mean, how do we destroy him? All we did was delay the inevitable. He keeps on getting stronger by absorbing negativity throughout the Multiverses; Ichigo, along with Ultraman and Akarenger, are holding their own against Dark Killer, and with dark chaos energy-boosting him up... well you already guess what happens next." said Decade, before he looks at Orb and Zero, "So, I heard you guys destroyed him once, how did you do it?"

Harry asked," Wait, someone managed to destroy the Dark Killer ?" He looked at Silver with a stunned expression.

Orb and Zero were silent. The last time they defeated Dark Killer was the time they combine their powers with Ginga, Victory, X, Geed, Rosso, Blu, and Grigio, by giving their energy to Ginga in which he executed the New Generation Dynamite.

"We defeated him last time, by combining our powers with Ginga to execute the New Generation Dynamite, " explained Zero, while Orb nodded.

Harry cried," They did manage to defeat The Dark Killer

"Then, what are you waiting for? Call out to the other Ultramen and woman to do this move!" exclaimed Gokai Red.

However, the two Ultras are silent.

"I'm afraid that's impossible Marvelous," answered Zero, while crossing his arms.

The pirate Sentai and Harry looked at him with raised brows.

"What makes you say that? If you guys destroyed him once, surely you can probably do it again!" argued Gokai Red.

Harry stated," I would like to know as well." He is a very curious expression

"We did! We tried using the New Generation Dynamite again, but this time it didn't work," explained Orb with a hint of frustration in his tone.

Harry thought," New Generation Dynamite?" He raises an eyebrow at the name of the attack as he is curious about it.

"When me, Zero, and the others encountered Dark Killer again, we tried doing Ginga's special attack, we did succeed," explained Orb, but his explanation is not finished.

The destroyer of worlds and Harry can tell there's a 'but'.

"But when we destroy him, his remains were engulfed in purple flames, and with that, he was brought back to life with his injuries gone and soon he got a lot stronger, overpowering us in our strongest forms," growled Zero remembering the beat down he got from the malevolent being

Harry's eyes widened in terror after hearing Ultraman Zero's statement as he learned that the Dark killer can use the ability of these heroes' foes.

Harry stated," Forget Vodlemort. The Dark Killer is a massive threat to everyone!" He felt a sense of terror after hearing about the Dark killer.

"Great! He can be reborn, whenever he got blasted to oblivion can this get any worse?!" exclaimed Marvelous sarcastically. He noticed the Destroyer who is deep in his thoughts.

"Oi Pinkie! What are you thinking? asked the pirate.

The Destroyer looked at him with annoyance, "First of all IT'S MAGENTA! Secondly, I noticed something from your explanation."

"What is it?" asked Zero.

"I noticed the part, where you said that; Dark Killer brought himself back together, by engulfing himself in flames right?"

Decade simply answered, "Remember, what you guys said to us that Dark Killer is a manifestation of the negativity from all the Kaijus and Seijin?"

The two Ultras acknowledge it, along with Gokai Red listening.

"Well after he was brought back to life, by his seijins and being infused himself with Dark Chaos energy, and my fellow Kamen Rider: W informs me with terrible news." said Decade with a grim expression, "He said that Dark Killer has found a way to embraced the negativity from kaijins from different universes."

"Different universes? Do you mean our universe where the Kamen Riders and Super Sentai reside? Gokai Red stated.

"*Nods* That right. And the worst thing is that the Dark Chaos Energy has given him a new ability. An ability that gave him the powers of all villains that we faced." said Decade in a serious tone.

"WHAT!?" exclaimed all three of them, shockingly.

Harry's jaw hit the ground in horror along with eyes widening in fear.

All of them are beyond shock(and maybe even terrified). Dark Killer utilizing the abilities of their past enemies, is scary no doubt. The three of them shuddered at the thought of the malevolent being using the abilities of their powerful enemies(i.e. Emperor Ackdos Gill, Reibatos, Belial, Great Leader of Shocker(not Decade), etc.)

"Also the part, where Zero said that he got reborn from flames, well he is using Phoenix's ability of revival, and that revival made him stronger," explained Decade. He remembered that Phoenix is Kamen Rider Wizard's enemy, and Wizard has a lot of trouble taking him down.

"Damn it!" growled Zero, punching a nearby stone wall leaving behind small cracks, "Then, what are we supposed to do!?"

Harry asked," What can they do ?" He felt their struggle, the sense of helplessness that they can't defeat a threat like the Dark Killer.

"I... I don't know." muttered Decade. For the first time in his life, he doesn't know what to do. He and his fellow Riders, always found a way to take down the jackass, that wants to pick on the weak or conquer their world. But now it wasn't since the enemy is too strong, even his ally Kamen Rider Zi-O, who is one of the strongest, who rivals his power has a hard time taking down Dark Killer, due to his powerful ability to adapt to his opponent's power.

Gokai Red is silent, after hearing this. He and his team always move forward and endure the hardships they went through throughout their adventures. Especially finding the Greatest Treasure in the Universe, which he sought out. Them teaming up with the Kamen Riders, his future successors and the more he learns, about what it feels like to embrace being a true Super Sentai and finding the greatest treasure he longed for, and that is the bonds with his team, along with his predecessors and successors. But now all of those things are gone, due to Dark Killer's reign.

Even Orb was troubled by this. During his journey across the universes, destroying Queen Bezelb and saving the Tree of Life, finding the elemental stones of the Orbcalibur, stopping a black hole that almost destroyed the universe, and destroying Maga-Orochi.

Harry shouted," You guys can't give up! You are supposed to be heroes! Heroes never give up in the face of danger!" He shouted towards the heroes until he remembered they can't hear making Sliver chuckle.

"GUYS!" called out Orb. The three heroes looked at him, "I know how we can finally destroy Dark Killer!"

The three of them looked at him incredulously.

Harry said," Let see what Ultraman Orb has to say." He looked curious about what his predecessor had to say.

"How Orb? No matter, what we do he always came back," said Zero.

"Zero remember the time, where we give our energy to Ginga for him to execute the New Generation Dynatime?" asked Orb, while Zero nodded, "Well, what if we gather up all the Ultraman and used up all of our Light Chaos energy combined it with the Kamen Riders and Super Sentai? Then we can use it to blast Dark Killer for good!"

Zero was shocked! How come he never thought about this? If they gather up all the Ultraman, along with the Kamen Riders and Super Sentai, they'll surely win, when they combined all of their Chaos energy.

Harry said," They are going to combine powers to take out the Dark Killer?" He looked at Sliver who expression turned stoic.

Sliver said," Keep listening." He gestured towards the memory.

However Decade and Gokai Red were silent, while that plan is great and useful, the two of them know the cost of it.

"While, I agree it's a great a plan and will surely give us an edge that can ensure victory, but you do know there's a price to pay if we do that, right?" asked Gokai Red, making the two of them silent.

"I agree with the pirate boy, even if we gather up all of our allies and use all of our Chaos energy, it will destroy us then possibly die," said Decade in a serious tone.

Harry paled in horror and he see the two Ultras go silent hearing. They never thought about that, they forgot the most important thing, about using every bit of Chaos energy in the body. If they used up all of it since Chaos energy is a manifestation of people's inner potential that balances between Light and Dark, it will completely suck up their life force, and finally, destroy their souls and bodies if use ALL of it.

"Yes, I know the danger and risks of doing it." said Orb, "But aren't we supposed to always risk our lives to save our loved ones and the world."

"I know, but..." Gokai Red started, but Orb cuts him off.

"Let me finish... Remember the moment we first transform into an Ultraman, a Kamen Rider, or a Super Sentai we always risked our lives to save the people from many threats that could end the world or kill our families. Even sacrificed our own life to preserve peace. A lot of our allies went through a lot, all of them sacrificed their normal lives to save the weak, and made all the people live happily. Sure all of us went through a lot, most of our allies witnessed their comrades die in front of them or their loved ones, but as long they keep on fighting and never give up, never submit to despair or sadness. AND THAT'S WHAT MAKE US AN ULTRAMAN, A KAMEN RIDER, AND SUPER SENTAI!" declared Orb with his speech.

Harry stated," Wow that was inspiring and a bit cheesy but It's a good pep talk." He smiled at Orb.

The three are speechless. How could they forget about it!? They are heroes who preserve justice and peace throughout their worlds, they always made a vow to risk their lives to save others no matter the cost.

"*Chuckles* Your right Orb, I almost forgot that the reason we take this role of being an Ultraman was to preserve peace in the universe, no matter what. I will gladly give up my life by your side along with our predecessors to save others." Stated Zero.

Orb nodded, "Thank you Zero."

"I agree with you. While most of us Riders, don't fight for justice, we fight for the sake of peace and humanity. The Kamen Riders will be at your side." said Decade, before he let out a small laugh, "Besides Natsumi will kick my ass if I stand around and do nothing."

Harry asked," Who Natsumi ?" He looked at Sliver who let out a deep chuckle.

Silver stated," Decade's main tormentor." He sees Harry crack a small smile as he picked up on what Sliver is implying.

The two Ultras let out a chuckle.

Gokai Red who is silent, while crossing his arms said, "You guys are making me soft. Heh, well then me, my friends, along with all the Super Sentai will also be at your side." Besides, they already found the greatest treasure in the universe.

"Thank you all of you." Orb thanked the three special heroes, "Now then let's unite all of our allies!"

sees

The three of them nodded.

Harry watches as the image fade away and he sees a new image.

Harry thought," Come on guys beat the Dark jerk" He crosses his fingers in hopes the heroes can defeat the monster.

Harry sees battlefield 3 figures are fighting a single being.

The first figure was colored silver with red. He has red markings all over his body covering half of the silver parts with his chest having a small orb, that is blinking red. This is Ultraman the original, who started the legacy of all Ultraman.

The second figure resembles a grasshopper. His helmet has red eyes with a mandible design and a mustache. He has a black suit with green armor on his chest. His arms are covered in black sleeves that accompany the suit with white gloves. His waist is a mechanical belt with a turbine design. On his legs, he wears white boots. This is Kamen Rider Ichigo the very first rider, who started the Kamen Rider legacy.

The final figure is covered in a red suit with a helmet. His helmet has a blue visor and on top of it has a symbol of bird wings. His suit has a yellow-colored 'V' shaped design accompanied behind his back was a red cape. On his arms he wears white gloves, on his waist is a black belt with an 'S' shape buckle with different colored stars. He also wears white boots. This Akarenger Red, the leader of Goriders, and the very first Sentai team started the Super Sentai legacy.

The three legendary heroes are fighting the one being, who started it all and that is Dark Killer. Right now they are being overwhelmed by the malevolent being, due to his adaptation ability, but the three heroes stand their ground against him, not giving up.

Ichigo let out a barrage of punches to Dark killer, but he just simply blocked it with his arms. After he blocks, energy began to build upon his blade arms, before he slashed the rider away, making him cry out in pain. Ultraman appeared behind with his fist glowing ready to strike him down. Only for the dark being to grab his arm, then throw him in the air while blasting him with his eye beams, sending him flying. Akarenger pulled out his Red Bute then quickly delivered multiple whip strikes to Dark Killer making him grunt in pain.

Dark Killer glared at him, "Killer Cluster!" The dark being fired a cluster of purple bullets at the red sentai. Akarenger used his whip and managed to block all of them, but he is overwhelmed by the sheer number of the blast before he got hit, making a roar in pain.

Dark Killer began to think himself, why are the three heroes kept on fighting him along with his army? Why do they keep on resisting, despite the odds against them? What fuels their fighting spirit?

"I'm impressed that the three of you last this long against me. Despite all the beatdowns, I gave to you all, and yet you still fight." said Dark Killer with amusement, "Normally, I don't do this to my enemies, but answer me this: Why do keep on fighting me, where I'm almost at my goal?

The very first heroes group together still standing, despite the injuries in their bodies. Their bodies filled with determination, as they glared at the dark being.

"It's because we never gave up to evil beings like you!" yelled Ultraman.

"That's right! Because heroes like us will keep on fighting no matter what!" said Akarenger with determination.

"You may blast us apart, erase us from existence, destroy our homes and families. But as long as people believed in our hearts. WE WILL STOP YOU! stated Ichigo.

"AND THAT WHAT'S MAKE ME AN ULTRAMAN/SUPER SENTAI/KAMEN RIDER!" yelled all the heroes of the first.

Dark Killer let out an amused smile.

Harry shivered to see that smile and he said," That an ugly-looking smile."

"While I admired your bravery and determination. All of it will mean nothing, soon the known Multiverses will be mine and nothing will stop me, not even you or your strongest allies can stop me" stated Dark Killer.

"Now time for me to destroy you." Dark Killer then charges up his Dark Killer Shoot, ready to destroy them.

The three heroes brace themselves for the attack, however, they felt some sort of message enter their heads. They were silent about the message in their heads before they quickly agreed.

"Say goodbye!" Dark Killer was about to blast them, until...

BLAST

Something blasts him preventing him to use his attack. Dark Killer glared at the sorry soul, who did that.

"Who dares interrupts me!?" demanded Dark Killer.

"We are!" yelled out multiple voices.

Harry and Dark Killer looked at the source of the voice and were shocked! In front of him standing on a cliff where all of the Ultraman, Kamen Riders, and Super Sentai all rounded up together like an army. All the heroes managed to take out all the kaijins, seijins, and kaijus that are on their way. The three first heroes were happy that their successors are here ready to destroy Dark Killer, for they knew the plan and they agreed to pay the price honorably.

Harry whispered," So many heroes." He looked at them in awe and amazement.

"So all of you think that banding together will stop me, huh?" asked Dark Killer, letting out a laugh, "I have all the powers of your enemies, do you think your abilities are enough to defeat me? Where I'm almost at my goal."

"That may be true Dark Killer! You may have the powers of all our enemies, but with the combined powers of all three great heroes along with the people, who support us we will stop you and save the Multiverse!" exclaimed Orb, while the other heroes let out a "YEAH!"

Harry shouted," Go Team Heroes!" He shouted to show some support for the team of good guys.

"Such heroic nonsense. No matter, time for all of you to be destroyed," said DarK Killer in a serious tone.

Dark Killer began to glow purple, along with his color timer. He spread his arms, then all of the kaijins and kaijus in the surrounding area began to have a purple aura. Soon all of them turned into an orb of purple energy and went to the dark being. The Dark Killer began to absorb all of the purple orbs, then he began to get big, and big, and BIGGER. As his size almost reaches the upper atmosphere. Now Dark Killer is almost big as the entire world.

This doesn't make all the heroes flinch or even scared, all of them stood their ground as they gaze at the gigantic being.

"PREPARE TO BE DESTROYED!" Dark Killer's voice boomed throughout the area. He began to charge up his Dark Killer Shoot.

Ichigo turned to his allies and yelled, "EVERYONE NOW! COMBINE ALL OF YOUR POWERS!"

All of the Ultraman, Kamen Rider, and Super Sentai began to glow in a golden color.

"SAY GOODBYE HEROES! DARK KILLER SHOOT!" Dark Killer executes his attack, as he blasts a continent-sized beam to the heroes.

All of the heroes let out a grunt and yelled, "ULTRA RIDER SENTAI BREAK!" All the heroes let out a similar huge beam, but it is golden color, as it collided with the purple beam.

Two of the beams clash, and each of them has a hard time pushing through however the golden beam is struggling to push through. The heroes began to struggle, tried to press forward, but Dark Killer wasn't going to allow it.

"OH NO, YOU DON'T" Dark Killer began to call upon more Dark Chaos energy, as he added more power to his attack making his beam powerful and it began to overpower its counterpart. Dark Killer's beam began to overwhelm the heroes, as they struggled against the sheer power output of his attack.

Harry cried," Come on heroes! Beat that jerk!" He shouted at the Heroes as they struggle with the Dark Killer.

"What?! How did they get so much power?!" exclaimed Dark Killer, "I can't let this happen!"

Dark Killer increases his power to stop the beam, but the hero's beam is a lot stronger now, before pushing forward. Dark Killer tried his best to stay put, but to no avail, the golden beam is inches away from him. The dark being tried to win, but now the golden beam struck him in the chest making him roar in pain.

"AAHHHHHHH!" roared Dark Killer. He felt a million stings of pain throughout his body, he tried to regenerate and be reborn again using Phoenix's ability, but with this amount of Light Chaos energy filling up his body, it's impossible.

With that his body is slowly fading away, while that is happening he began to think, "This is how I got defeated huh? *chuckles* You Ultras, Riders, and Sentai continued to surprise me." thought Dark Killer, and finally embraced death, cause he does not fear death. However, with his remaining life, he began to think that this is just the beginning.

Harry watches as Dark Killer is engulfed by the large golden beam that is almost the size of the planet, and it finally destroyed him leaving behind a giant explosion. He felt a smile grace his face as he watched the Dark iller be destroyed.

Harry cried," They did it! They beat the Dark Killer!" He was about to jump for joy in support of the death of the Dark Killer.

" But not without a price.''

Sliver's voice gets Harry's attention and he watches as a golden light that engulfs the heroes, their bodies are vanishing since they used up all their Chaos Energy within their bodies and soul, however, they sacrifice their lives in the sake of others and their loved ones.

Soon the golden light that engulfs the three groups of heroes vanished. What's left of the Ultraman, Kamen Riders, and Super Sentai are now gone, what's left is just a battlefield with the spoils of war.

(A/N: Think of the battlefield as the Keyblade graveyard except without the Keyblades lying around.)

Harry cried," What happened to them? Why are their arsenal left on the battlefield?" He looked at Silver.

Sliver said sadly,' Those brave heroes sacrificed themselves to stop the Dark Killer but I am afraid it only delayed his plan for he has risen again." He shows another image of the Dark Killer being risen from the ashes to Harry's horror.

Note: Well here is the new chapter and we learn a bit more about the Dark Killer and what happened to the Heroes who defeated him in the past. What should happen in the next chapter? How should Rebecca make an appearance in the next chapter? Shout to my homey the Nexus Warrior for allowing me to showcase the backstory of the Dark Killer and the heroes.
