Sonic the Hedgehog Meets Den-O

One day, the Hero of Mobius, Sonic the Hedgehog, was running through town to meet up with his friends. It was quiet that day. A little too quiet. As he met up with his group of friends, Tails spoke up.

Tails: "Hey Sonic. Sorry to say this on a day like today, but I saw something on the radar."

Sonic: "What is it, Tails?"

Tails: "I have no idea, but it seems to be in the shape of…"

Sonic: "The shape of what? Robots? Ships?"

Tails: "A train."

Sonic: "You can't be serious. Is this a joke? I'm not laughing."

Then Silver, who was helping Tails in the lab earlier, spoke.

Silver: "He's serious. But for some reason, the train appears then disappears in different locations."

Sonic: "Weird."

Shadow then pushed Sonic out of the way as a huge train appeared out of nowhere on a track that was coming from a wormhole in the sky.

Shadow: "Hmph. You're welcome."

Sonic: "Thanks. I guess."

Shadow: "What the heck is going on?"

A door on the train had then opened up and a young teenager stepped out. A red, blue, yellow, and purple figure could be seen in the train. The young kid had then bowed and spoke to Sonic and his friends.

???: "Hello everyone. I'm sorry to disturb you, but we have come from Earth to find a creature. We followed him through time to this location."

Sonic: "We haven't seen anything, but mind if I ask who you and your friends are?"
???: "Of course. My name is Ryoutaro. These are my friends Momtaros, Urataros, Kintaros, and Ryutaros. When one of them…. Er…. Possesses me,  we become Kamen Rider Den-O."

Sonic: "Kamen Rider? What?"

Ryoutaro: "Kamen Riders are defenders of peace and justice in the world. I am one of 41 Riders."

Momotaros: "That's right. Ore… Sanjou!"

Urataros: "Boku ni tsurarete miru?"

Kintaros: "Nakerude!"

Ryutaros: "Kotae wa kiitenai!"

Sonic: "O-kay then."

Just as they had introduced themselves, the Imagin Ryoutaro was looking for snatched Amy and Cream.

Imagin: "I am the Gazelle Imagin! Try anything funny and these two little girls will die!"

Amy: "Help!"

Ryoutaro: "Momotaros! Let's go!"

Momo: "Right!"

Momotaros jumped into Ryoutaro's body and possessed him, causing his hair to spike up with a red streak and his eyes to turn red.

Momo/Ryou: "From start to finish, I am the climax. So now, watch my cool henshin."

Sonic: "Henshin?"

Momotaros pulls out a belt, wraps it around his waist, presses a red button on it, and a strange sound comes from the belt.

Momo: "Henshin!"

Momotaros had then waved a black device, known as a Rider Pass, over the belt, causing it to say Sword Form. The Rider Armor then attaches to his body and his helmet changes from solid black to a red peach-like mask.

Momo: "Ikuze, ikuze, ikuze!"

He then takes these pieces of a weapon off of his belt and assembles them into a sword and attacks the Imagin. At the same time, Sonic snatches Amy and Cream from the Imagin.

Sonic: "Run!"

Amy: "Thank you!"

As Amy ran off, Ryutaros gets restless and possesses Sonic, making a purple streak in his quills and obtains headphones and a brown hat.

Ryu/Sonic: "Mind if I join in?"

Once he said that, Ryutaros begins break dancing.

Sonic: "Hey! Get in the fight! Don't just dance!"

Sonic then realizes that Ryutaros' dance moves are also combat moves, kicking and flipping around to land blows on the Imagin. The battle is a hectic one, but the Gazelle Imagin escapes.

Momo: "Crap. We gotta go after him!"

Ryu: "We better get going!"

Suddenly, Silver and Shadow run up, but Silver is possessed by Kintaros with a yellow quill streak and a kimono, while Shadow is possessed by Urataros with a blue quill streak and glasses.

Ura: "Let's get on the Den-Liner and follow him."

Shadow: "GET OUT OF MY BODY!"

Ura: "No can do, Shadow."

Kin: "We can't escape your bodies."

Silver: "WHAT!? WHY!?"

Ryu: "For some reason, we are stuck until we find that Imagin."

Sonic: "*sigh* Well we better get moving then!"

Momo: "Right!"

Ryou: "All aboard!"

They all enter the Den-Liner and take off to find the Gazelle Imagin.
