King Dedede entered the mysterious castle. He trembled a little as the eerie atmosphere brushed his feathers. He noticed the castle was rather old. It surely wasn't his own, because his castle was more elegant and clean.
Then, Dedede noticed a mirror. It looked familiar, but he couldn't exactly remember what kind of mirror it was. He stared into it, but he couldn't see his reflection for an odd reason. This made him a little more nervous. The king turned away from the mirror and began walking away from it.
Suddenly, there was a sound. It resembled that of a gentle, yet spooky wind. He turned around and looked at the mirror, but nothing appeared to have happened. But as he turned away again, a dark orb appeared inside the mirror, with a loud, distorted warbling noise.
Dedede quickly faced the mirror and noticed the orb was changing shape. The orb began resembling him in some way. Except the structure was evil, which was something the world always assumed was true about Dedede. They were, of course, incorrect.
Then, the shadowy-looking Dedede leaped out of the mirror with a roar. He attacked the real Dedede by jumping at his face. Dedede screamed and kicked the fake to the side.
The clone of the king got up, laughing creepily. He introduced himself as Shadow Dedede. "I have been waiting for so long for someone to stumble upon this mirror," he said with a grin. "And it looks like the one who did it was none other than my doppelganger."
"Um, I don't understand..." King Dedede stammered. Why did you attack me?"
"Oh, that's an easy question," the clone replied. "I attacked you so I could KILL YOU!!!"
Dedede prepared himself for the biggest fight of his life. He pulled out his hammer, and Shadow Dedede mimicked him, summoning a hammer of his own.
And just then, the fight was on.
