From the Inside Out

by TheBestEver222

Xana's up to something, but the group can't figure out just what. And when Odd starts hallucinating things that should really be left to the dark recesses of a maddened mind, he can't quite put two and two together. But what if it's not Xana at all? What if it's just him and his rapidly degrading sanity? Rated high T for gore, nightmares, and the such and such of Odd's suffering.

1. Prologue

Hello my little readers! Okay, so I finally have another story that's not a oneshot or a twoshot. About time I did that. So, this is my first Code Lyoko story, and I know I'm definitely too old for this show, but I really don't care because IT IS MY FAVORITE THING IN EXISTENCE. I love this show, so I just had to write a story about it, and Odd is my favorite character, so I just had to torture him. Anyway, hope you enjoy the prologue. I'll be updated this every Monday, and it'll only have like seven chapters or something. And I know this is short, but it's a prologue, so it's allowed to be short. Don't make fun of it for it's height.

Disclaimer: I do not own Code Lyoko. If I did, you could bet that there would be a lot more Sibling!Oddlita and a lot more of the shipping of ships.

It was late at night. The Moon hung high in the sky, providing the only other light aside from that of the stars. Below ground, inside a once long-forgotten room in an old, abandoned factory, the soft humming and whirring of machinery echoed off metal walls. The room, as well as the rest of the building, was unoccupied then, or so it was thought to be. But the sound of mechanical doors opening belied the apparent emptiness.

Out of one of the capsules that lie within the deep recesses of the building came a creature, so small that one would miss it if they weren't looking. Roughly round and with six legs, the creatures was mostly black, its only inconsistency in color the even tinier symbol printed on its back. The insignia looked sort of like an eye, though somewhat misshapen, and it glowed a faint, ominous purple.

Where the bug had come from may not have been very important to most who would encounter it that evening, for various reasons, but to the one person that the creature was after, the information of its origin could not have been more vital. Its creator was none other than the being called Xana.

And as the bug crawled through gaps in doors and floors alike, its creator felt somewhat giddy. He would be rid of those pest who always managed to stop him once and for all. He'd get rid of them, one by one, so slowly and inconspicuously that no one would know what was going on until it was already over.

He altered that stupid boy's program so that he couldn't detect an activated tower, and Aelita was now back on Earth rather than in Lyoko. She wouldn't be able to detect anything that the program did not, so they would not find out until it was too late to save at least one of the brats. And then the others would be so upset over the fact that their friend was too overcome by madness to recognize them, they'd probably be incapable of doing much. So long as they did not find it until the process was complete, they wouldn't be able to do anything.

His plan was fool proof, exceptionally so. The creature would burrow beneath the skin just under the hairline, where it would toy with the mind of its victim, and where no one would see it unless intently looking for it. And slowly, it would destroy the sanity of whatever organism it attached itself to, until eventually there was nothing left but tattered remains. And what better way to drive someone insane than with visions of them murdering those they held closest to their heart?

He'd start with the one who looked like a cat, slowly corrode his mind until he was too far gone to function. He would destroy their little group one by one, from the inside out.
