Rise of the Nightmares

Sequel to "The Power of Dreams"
NOTE: This is a rewritten version of the third part of my first fan fiction series on my DeviantART page. I thought I'd also post the rewritten version here on Wattpad to share it with more interested readers.

Plot:
Mario has always fought King Bowser and his goons. No matter how dangerous the situation is, Mario will always trek through even the toughest lands to rescue Princess Peach from Bowser's grasp.
Sonic has always fought Dr. Eggman and his robots. Going all around the world, and no matter how disastrous Eggman's plans are towards the world, Sonic, along with his friends, will fight till the end.
Kate has no recollection of fighting in her forgotten past. Though after meeting Mario and Sonic, she found herself caught in their battles against Bowser and Eggman. But her powers may be for another threat.
The three friends may have understood what Kate's power is. The Power of Dreams. But it seems that there was another reason why Kate had to understand her powers. A reason why she forgot her past and why she has her powers. A reason why she was brought to Mario and Sonic's world. A reason that endangered her, and has now put Mario, Sonic, and their friends into danger as well. And it's not like Bowser, Eggman, or any of their schemes. This threat is difficult to identify, when the only clues lie in nightmares that Kate is having.
This is the point of discovery in the tale of Mario, Sonic, and Kate. This is the dark twist in the Tale of the Tale of the Three Heroes.
