The stallion had expected this to happen but it still hurt to explain what to him was fact of life. "I see I'm going to have to start at the beginning," he said to the purple alicorn before him. "I am Kamen Rider Decade."
The stallion then reached toward his midsection and seemed to grab some form of device which Twilight had not noticed before. As he did his body and armor seemed to dissolve in pink, squares, yet as they did they left the stallion changed. His coat remained the same color, but his mane became more even and a shade of soft brown. His armor had completely vanished and was replaced with a red turtle-neck and brown trench coat. He also had a small box hanging around his neck. His cutie mark had changed as well, it now showed what appeared to be a roll of film negatives, each showing a green and blue sphere. The pony looked much less intimidating but still just as unusual.
Twilight was speechless, "... Waa?" mostly.
The strange pony moved to his left, as he did so the void surrounding the two ponies vanished and was replaced with the castle's throne room. "This seems more appropriate," Decade said, "A Kamen Rider is a warrior who fights to protest the populace from evil. Basically, I'm from another world. And I bring you, Princess Twilight, a warning."
This finally seemed to knock Twilight back to her senses, "I'm listening."
"I'm a traveler of sorts, I've seen many worlds. However the world that I've called home for a while is in danger, and so is yours.
"My world has been plagued by a species called Kijin, there kind have devastated our nations, and killed or consumed most of our people."
"Consumed?" Twilight was familiar with species who ate the the flesh of others, but it still sent a chill down her spine to think of anyone being eaten.
"Yes, and now they have found a way to travel to other worlds. Your world is their first target." Decade sat down in the throne opposite from Twilight's throne. "You have been chosen as this world's defender."
Twilight was shocked, "Me? What can I do?"
"I've been observing your world, I haven't seen everything but I get the gist of it. You have the potential to resist there invasion, but only if you become a Kamen Rider."
"You mean like you? With the armor, and the weird mane and the, whatever that just was." Twilight was beginning to panic again, she had been entrusted with some huge responsibilitys in the past year, but this was crazy.
"Just the armor, my armor in fact. It will form to suit your species, just as my form is projected to you as a comfortable form."
"Why do I need it? You said Equestria has potential and we've dealt with invasion before."
Decade rose off the throne and approached the Princess. "You magic is too passive, to defeat the kijin you can't just banish them, you will have to destroy them."
Twilight gasped, "No. No it's too cruel!"
"They are murderers! Blood thirsty killers that will not show mercy or restraint." He paused and turned to the window, "And you need to make a choice: either hold onto your beliefs that there is no such thing as pure evil and die, or accept the help of my people and have a chance of living." Decade took a few steps away from the window and faced the princess of friendship. "Come to this room when your mind is made up."
With that the pony moved toward a wall where the void from before was descending like a curtain. Twilight felt herself going numb and fell into an unconscious state.
Twilight felt like she had just been the victim of Pinkie's twitchy tail, during cider season. But the memory of her dream was still fresh in her mind.
"Twilight, are you okay?" said Spike who was at her bedside, "I heard you yelling in your sleep and I came to see what was up."
"Oh, what time is it?" Twilight asked, groggily.
"About 3:30."
The alicorn rubbed her eyes, "Oh, I had a weird dream. This crazy pony said I had to kill monsters that were invading our world."
Suddenly, somewhere in the castle a large crashing sound was heard.
Spike and Twilight both looked in the direction of the sound. Spike said, "Either that wasn't a dream or the IRS finally decided to start taxing political figures."
