Once upon a time, in the mushroom kingdom, 5 years have passed since 2010. During this period, many things have change, special friendship broken and, the danger will go further because of Bowser and his minions. It happened during a rainy and stormy night. Bowser and three minions explore the cavern, they hope to find a secret weapon to kill Mario and his friends, because Bowser has not *Again* won his battle againist his arch enemy, Mario. So he want to find a secret weapon to kill him for good. Bowser and his minions start to talk.

« Brrrr, it's freezing here, i wonder if we did well to come here? » Said the first henchman, shivering, a little scared.

« Anyway, me, i'm scared! » Answer the 2nd minion looking around, hoping not to get killed.

« Pfeuh, you're really fagot you know? » Asks Bowser very rude, turning to his 2nd henchman, continuing to walk backwards. «Keep your tall tale for you, me, i'm not scared » He continues very rude again.

The minions look the very dark and scared cave, on the edge of collapse and the walls filled with cobwebs, they understand that nobody visited this cavern for ages, they were not able to take a step without shivering or pushing little cries. Bowser, meanwhile, continue to walk, committed to seeking any secret weapon who've been abandoned.

One hour later, they find a kind of large coffin, with a red Yoshi, the Yoshi looks really bad, and his body was black and not white, and he have black hair a little raised.

« What is that? » Thinks Bowser, surprise, he's never seen it before.

Meanwhile, in a white world like a dimension, the same red Yoshi trains on weight and battle, right now, he gives punches and kick in the air, but it was not his body, it was his mind who was training. The coffin was used for meditate, for ages, the red Yoshi meditate for his mind goes train in his world, and when someone would open the coffin, his mind will return to his body and he will have accumulated enough strength to defeat the one he wants to kill. That's 15 years now he is here.

« It will take the time it takes, but i will return, and i will take my revenge on you, Yoshi! » Said the red Yoshi continuing to train.

Yoshi? This person knows Yoshi? But why he want to kill him it's a story that we will know soon. The fighter suddenly hears a sound. He looks through his world and sees Bowser open the coffin.

« Finally, i'm free! » Thinks the red Yoshi, returning to his body.

Back in the cavern, the body of the unknown Yoshi raises, and open his eyes.

« Yes, it's alive, i will finally use you, dear Yoshi, to kill Mario! » Bowser said, shouted with joy.

« What, you think that i, YoshX? Will work for you? » Asks YoshX, surprise and put his left fist in the air.

« What? » Said the reptile, a little disappointed.

« Where is Yoshi? It's him i want! » Said roughly YoshX, jumping out of his coffin.

« Oh, you want Yoshi? Why you don't work for me in this case? » Bowser asks, understand anything.

« This is not concern you, and if you don't settle, i will kill you, you and your pathetic minions! » YoshX orders, a little angry.

« No! » Said Bowser, not intend to let him go.

« …Well…in this case… » Said slowly the evil Yoshi.

« …What? » Asks Bowser.

YoshX gives an uppercut to Bowser, who falls on the ground.

« OH MY GOD, RUN AWAY! » Said the first minion, run away with his companions.

« I knew it, that wasn't a good idea! » Said the second thug, dissapoint that Bowser have done.

« Shut up and run away with us! » Orders the third minion, continues to run away.
