Ore, Sanjou! This is a continuation of the old version of MLP FiM meets Kamen Rider Decade.

Thank you momotaros....

Now if you'd please remove yourself form my body we can begin, besides we've pretty much destroyed the 4th wall here....

Oops!

Owner, if you would?

The train of time: Den Liner! Where will it's next stop be? The past? The future?

Last time, Momotaros had been attacked by Hanna and he wound up in present day equestria, a land filled with colorful ponies, colts, mares, and stallions with minds not unlinke our own. He lashed out about being the butt of everyone's jokes and used his rage to become his own dark counterpart: Negataros!

He used Negataro's ability to become Nega Den-O without needing to posses anyone. He was defeated by the land's ponies and his fellow kamen riders by an attack based on the world's strongest magic!

However he was still stuck there, you see he had fallen off the den-liner recently and landed not just in another time, but another place! For you see, while Kamen Rider Decade can travel across space freely, time travel involves going across both time AND space.

Normally we do not travel across alternate time line so far apart form our own, but Hanna had hit him pretty hard! Heh heh heh.

Thank you owner, I'll take it from here.

Little did anyone realize, that with Decade opening a link to the rider's worlds, villains from those worlds would be able to enter as well as the Six riders with that kind of power: Decade, Diend, Den-O, Zeronos, and Yuuki and New Den-O. But this story will not quite include New Den-O or Yuuki, maybe another time, maybe not...

Using that link, an imagin few through. The pony imagin of course! She saw several decent options, Rarity, Rainbow Dash, Apple Jack, but then, he decided on some one else, Fluttershy! She flew down and said "Tell me your wish! I will grant any wish, as long as you pay one thing! I assure you it's nothing you will miss, don't worry little one!"

Meanwhile the Den Liner and Zero Liner had arrived, dropping off Ryotarou, Yuuto and Deneb. As soon as they got off they were transformed into colts. "EEEEEEEEEEEEH?!" Ryotarou exclaimed "What's going on?!" Yuuto, seemingly un-phased just reminded him, "Owner did mention that this is an alternate time line, to be honest I was not expecting this, but it's not a big deal."

Ryuutaros possessed Ryotarou and asked "You sure? Oh well!" He then summoned a gang of dancers to help search. "Hah! These guys sure dance funny! Ok! Go find my friend ok?" Deneb was amazed at Ryuutaros' power "You can even do that here?! That's amazing! You really must teach me how t-" He was cut off by Yuuto "Deneb! Shouldn't you also be searching by now?" Deneb fumbled a bit before realizing he couldn't bow and instead kneeled "Sorry! I'll get right on it!"

Meanwhile Princess Celestia had been observing things through her servants. "Seems things are going to get interesting!" Momotaros had been found by the Royal Gaurdsmen and had been put in a prison cell. Naturally he wasn't taking it so well... "HEY! LET ME OUT! So I let my anger consume me and caused a bit of damage, I'm calm now. SO LET ME OUT! Oh I hope they find me soon!"

Back in ponyville Twilight Sparkle and her friends were at Twilight's libary, except fluttershy who was late. "So why have ya'll corralled us here fer again shugah?" Apple Jack asked in her southern accent "Well, after the decepticons and that weird oni pony there's been a lot of trouble lately. I'm working on a way that we can boost our own power based on the powers the kamen riders have. We don't have the technology they do, but /I/ have the magic. Based on what I've seen I may be able to manifest our own rider systems."

The other ponies seemed rather confused, especially Apple Jack..."So yer sayin' yer magic can create those doohickies on their belts?" Twilight shook her head "It's a bit more compicated than that. The spell will only work if I have one of them to base it off of. I can't just make things appear out of thin air, REAL magic doesn't work that way."

Deneb had been outside the window eavesdropping. When Twilight mentioned a 'wierd oni pony' he had contacted yuuto though their mental link. By the time she mentioned her need for a rider system, R-Ryotarou and Yuuto had arrived "You need one of these?" R-Ryotarou held up the Den-O belt. "Can't hear ya!"

Some more dancers had appeared and surrounded the ponies "What in tarnation is goin' on?! And where is that awful music comin' from?" Apple Jack demanded obviously not a fan of hip-hop. The dancers closed in on them, poised to strike, but then Ryotarou told ryuutaros "I think we should help them!" Ryuutaros left Ryotarou but not before saying "Aww I wanted to have some fun too!"

After explaining how the imagin possessed him in order to become Den-O he said "I'm not sure how well my belt will help you. Without them I can only become Plat Form, which has no weapons!" Twilight just smiled and said "That's O.K., I'm just basing it off of your technology, our rider systems will be much different in the long run. Ours will be based upon the most powerful magic in all of Equestria, the elements of harmony!

Later, after twilight finished making the rider systems, she exclaimed "Looks like that one colt who claimed be a time-lord was right, magic and technology really are the same in the end!" From the Den Liner Ryuutaros exclaimed "Isn't that infringement?" Urataros simply said "No, that would be a vague allusion or a reference...." She passed out the rider systems. It was then she realized that she only made five, and that Fluttershy was missing.

Just then Fluttershy entered the room but she was possesed by the Pony Imagin! A-Fluttershy shouted "YOU WILLL RESPECT ME!" Yuuto glanced at her and said "An imagin!" Rainbow Dash sighed and complained, "I'm guessing she's not one of yours?" Ryotarous and Yuuto grabbed their belts. But Twilight shouted "Wait! Let us test our new power!" Yuuto looked to Deneb and said, well if it works, I won't need to use the card at least..."

"Henshin!"
"Transform!"
"Transform!"
"Transform!"
"Transform!"
"Transform!"

The imagin dropped it's hold over Fluttershy and said "You're all too late! The contract is complete!" She announced as the door to the past opened in Fluttershy. Seems her wish was to be a bit more assertive. Natrually the imagin twisted her wish and barely even half-granted it. Seeing this, Celesita released Momotaros who rushed to the secene. "Hey! Who are the wannabes?" He asked? "No time to explain! An imagin just flew to the past!" Yuuto said in a commanding tone.

The Den Liner and Zero Liner appeared, Twilight used her magic to finish Fluttershy's rider system and to summon a new Time Train, the Pony Liner.

"Transform!"
"Henshin!"

The three trains linked and traveled to October 23, 2010, the day after the six friends had defeated Nightmare Moon. Pinkie was holding a victory party that day of course, Fluttershy had made many good friends but was still much to scared to talk to them. She was really upset. It was then that the Pony Imagin arrived. Just as she arrived, a strange stallion in a trenchcoat was looking at the pocket watch around his neck...the three trains arrived and he pocketed it trotting away...

The pony imagin laughed at the riders and split into eight. "Good thing I was prepared for this, our leader didn't underesitmate you six!"

"I've.... Finally Arived! From start to finish I'm always at the climax! And I really hate how you evil imagin don't properly grant wishes!" Den-O Said "Let me say this to start, I'm pretty annoyed!" Zeronos said. "Um, we're going to beat you now..." Fluttershy said softly. "We're gonna make like cowcolts at a rodeo and rope ya'll up!" Apple Jack announced "I'm too fast for you!" Rainbow Dash said with her ego as big as ever. "We simply can't stand for anyone messing up time, that's even worse than messing up their hair!" Rarity complained. "Let's Party!" pinkie pie exclaimed.

They battled but were all having a fairly rough time "Come on Deneb!" Zeronos shouted, as Deneb came up and fused with him

-=Vega Form=-

"Let's join together too!" Ryorarou said.

-=#Climax Form!#=-

The imagin that were part of Den-O all said their catch phrases... "Mind if we reel you in?" "Can't Hear ya!" "You'll weep before our power either way!"

Deneb said his own "Let me say this to start! ...I AM REALLY CONFUSED!" "DENEB! You really should get your own catchphrase!..." Yuuto complained...

Deneb and Den-O mananged to get the upper hand for their respective opponents and prepared their finshers.

-=Full Charge=-

-=#Charge And Up!#=-

"Histastu, our Hisatsu atatck! Pony Version!"

Meanwhile Rainbow Dash had started using her wings as and advantage and managed to gain the upper hand for the other five. Twilight looked to the others, "Ready?" She asked "Ready!" the other shouted.

-=Elements of Harmony=-

"HARMONY RAINBOW BREAKER!"

after finishing off the rest of the imagin Ryuutaros complained again "Ok THAT has got to be infringing..." he didn't quite understand copyright laws it seems...

Unfortunately the defeated imagin had become 4 Gigadeath Heavens and 4 Gigadeath Hells. Just then, the kingliner appeared. "Good timing!" Yuuto said as they all borded the Den Zero and Pony Liners.

The four trains attacked with the front car of the Pony Liner's unicorn horn blasting the gigadeaths, with Apple Jack's car opening up to show a giant pair of rear legs that bucked at the Gigadeaths. Rainbow Dash's car shot violent gusts of wind and lighting. Fluttershy's car revealed various insects like bees, wasps, hornets, and mosquitoes. Raity's car was like Den Liner's bolder launching car but it launched razor sharp diamonds instead. Pinkie's car launched exploding gag pies....

The gigadeaths were destroyed and all of the trains returned to the present as the past was fully restored with no one or nothing being forgotten...However, the effects of Twilight's magic had been too straining for her to maintain any of it and the rider systems and the pony liner vanished into sparks... Another unexpected side effect was that they all forgot what happened or who any of the kamen riders were. Ryotarou was naturally upset by this but Yuuto being Yuuto told him "It can't be helped. It was purely experimental. They helped us with untested power and paid the price. Though I'm glad I met them.

Decade came and sealed the world off from the rider's worlds saying "Probably better that they don't remeber that any of us are just passing through kamen riders." before leaving again with the Den and Zero liners just ahead of him.

Owner, you may finish if you want.

Ok!

It truly is a sad ending, but instead of Twilight and friends learning something, it was Ryotarou who learned something. Something that he himself may have forgot over time. That they must fight to protect the world even if it means losing something important. Yuuto knew this, but Ryotarou never truly accepted it. After seeing the ponies' sincere emotions, he knew that Zeronos had to fight. Whatever the cost may be...

Author's Note

First draft originally posted to deviantart on Jul 19, 2011. It's still a very rough draft, but I never got around to working on it more.

There's a bit of metafiction here, but it's not indicative of the whole chapter.

Original notes:
I was tired while writing this and it was hastily written. I hope to proofread all of what I put up so far when I wake up...

This may also help fill a few plot holes even but that's not what motivated me to make it...I actually have been watching Den-O lately.

This would probably be a side story shortly after Ryotarou realizes what the Zeronos cards really are.

Sadly I could not reasonably include Sieg...
