Unbreakable - Chapter 148 - Revisit

You know what’s great? Turning eighteen.You know what’s not so great? Opening your eyes to a room you don’t know, followed by the world's most intense headache.This is how my story started. Where it goes from here is anyone's guess.---This is a Pokemon fanfic about a girl that gets brought into the Pokemon world from Earth.---This is my first time writing a fanfic so take it easy. Helpful criticism is appreciated and I may ask for suggestions but in the end I am writing this because I want to. I'm not sure what tags and genre will encompass this story but I will update it as it evolves.

Copying a skill itself was very bad-assed, and you mean to say he could evolved the copied Skill ten times it's initial power, exponentially surpassing the original owner?Why would the gods let such broken talent even exist?'Well it's just one way to find out...'Luckily just then, he saw two powerfull beings fighting mid air. Their fight sent shockwaves billowing in all directions, causing Nox to take a couple of Steps back.At that moment, he activated his talent...[Mimicry activated!][Target: Cosmic Entity Arkea - Successfully copied Skill “Gravity Manipulation”!][Description: Gravity Manipulation Creates a localized gravity field, slowing enemies within a 5-meter radius by 20% for 5 seconds.][Upgrading Gravity Manipulation 10x!][Ding!
