Percy Pov

Percy life had become amazing. There had been no monster attacks recently, and no depressed, unclaimed kids. The gods had kept the promise that Percy had binded them to, when he was granted one wish for saving the world from Kronos. That war had been over a month ago, and now all was well. Annabeth, the beautiful daughter of Athena, had become his girlfriend. The fact that they were dating had subjected them to a lot of teasing from their friends.

Today had been quite normal for Percy. He had gone to his usual lessons, and hanged out with his friends. Except, during this he had this feeling, something was going to happen soon, and it was not supposed to happen. Percy wanted to share his feelings to Annabeth, but something held him back. It was like there was a presence around him, not evil but powerful. At the campfire, the presence disappeared momentarily so Percy manged enough courage to tell the others,

"Guys, there is some sort of presence here, but its gone for now, also I have been having this feelin-"Percy suddenly felt a hand clamp over his mouth. He looked down, and saw nothing, which confused him because Annabeth was the only one he knew who could become invisible in Camp Half-Blood.

"Are you okay Percy?" Annabeth said, looking concerned. Another hand made it's way to his throat, his hands clawed against it, which probably looked odd to others considering the hands were invisible. The hands moved to his shoulders and he only had time to scream before everything disappeared.

++I am your overlord! BOW DOWN++

When Percy woke up, he was in a unknown place. It was a medium sized room, that was completely blue. There was nothing in the room, nothing but Percy. Percy noticed that the room oddly smelled like the sea, which made Percy wonder where the smell was coming from.

"Where am I?" He groaned out as he stood up.

"Nowhere." Said a voice behind him. Percy turned around and saw a girl materialize into the room. The girl was Asian, with golden-brown skin, messy black hair and eyes, and glasses. She was about thirteen, clad in gray skinny jeans, a unzipped blue hoodie with a purple shirt underneath, and black boots.

"Who are you?" He asked suspiciously, and the girl smiled.

"I do not wish to tell you my real name, so call me Cassandra."

"So where are we?"Percy asked again.

"We are outside of your universe."Percy raised a eye brow.

"What do you mean were outside my universe?"

"I think we should sit down before I start explaining." Cassandra said, before waving her hand, making two couches appear. Percy's eyes widened, is she a goddess?

"I am not," She said, reading his mind, "I am much more powerful." She is more powerful than the gods? Percy opened his mind to speak but Cassandra interrupted him.

"Save your questions for when I am finished." Percy nodded and she started explaining.

"This may seem odd, but I am from a different universe. In my universe, everyone is a mortal you could say, but there is certain people with a special power, the power to create. I am one of those people, I have the power to create universes."

"Wait," Percy interrupted, "People can make universes?"

"Yes, except people usually don't realize when they are. Actually only about four hundred or so people know of this power. Anyway, with this power we created your universe, well all of your universes. There is a main timeline, the person who made the universe makes that, and then alternate timelines. So basically in my universe someone makes a book that creates the universe, and others create different fanfiction about it, which makes the alternate timelines. But, this is not only limited to books, it's anything; movies, manga, t.v. shows, even thoughts. Also, in my universe, if you believe in a universe hard enough you could gain powers from the universe. So basically I am all powerful and I can control all of the universes and alternate timelines I created. Whoa, I sound like a Mary-Sue." Percy was shocked, this was crazy! But, for some reason Percy felt like Cassandra was being truthful.

"But, how am I involved in this?"

"Well, we are having some problems. Some idiots have created a super species, all powerful, overly perfect beings. They are Mary Sue's and Gary Stu's. They are usually recognizable, they have multiple godly parents, or an extra power, and they are extremely beautiful or handsome. I am unable to dispose of them because all of majority of my powers have been used on a universe that ended up crashing. So, now I have to use you to destroy those freaks of nature once and for all."

"But, wouldn't that disrupt the universe?" Percy asked. Cassandra shook her head

"No, because you are part of a alternate timeline, so I can mess with it all I want." Percy felt slightly uncomfortable at this.

"So, will you help me?" Percy thought it through and agreed. Cassandra squealed and threw her arms around him.

"Thank you!" She exclaimed, suddenly they heard a phone ringing. Cassandra pulled out a black flip phone and answered it.

"Yes, alright. No I will be there in an hour." Cassandra smiled and spoke to Percy.

"That was La, she is a daughter of Hermes, and she is from my universe."

"Are you a demigod too?" Percy questioned.

"Yep, I am a daughter of Apollo." She answered.

"So how am I going to help you with your Mary Sue problem?"

"Simple, I am going to transport Mary Sues to your universe, so that you can eliminate them." Percy nodded, and Cassandra pulled out a IPOD and looked through it for a second, then sighed.

"Only La would create a universe where she is dating Connor Stoll."

"I thought you said she was a daughter of Hermes."

"Your point?"Percy was a little disturbed by this, but just let it go.

"What if I make mistakes?"

"Don't worry," Cassandra opened her palm produced a simple leather cord bracelet, with a sun charm on it, "Take this, it will summon me to you if you need help, but otherwise I will be watching from afar." Percy took the bracelet and stood up.

"I should go, Everyone is probably freaking out about me." Cassandra nodded and said,

"Only three hours have passed, and when they find you say that you were kidnapped by a monster, but you killed it." Cassandra snapped her fingers and Percy felt a weird feeling in his stomach.

"Good Luck Perseus Jackson" Cassandra said just before Percy was surrounded by black.

Like it? I know I made Cassandra (who is me by the way) and La seem like Mary Sues, but basically everyone on fanfiction have this power. Also we can't use a power from a different universe in any of the universes. So if your in the A:TLA universe all you could do is the creating powers and bending unless it is crossover universe. This will be explained in a later chapter to Percy. Anyway, as you could tell this is a shot against Mary Sues because they annoy me greatly, especially when people Mary Sue real characters. By the way I will update the Therapy story tommarow...maybe. So R&R :)

~Cassandra (Who is never telling you her real name)
