This is a Pokemon x Mega man crossover fic I thought of one day. I do not own Pokemon or the Mega man series I only made this for fun.
Ps this in a world where both series are as one ok?
Also some things will be different but mostly dialog because it is hard to remember it all. Also there will be swearing in later chapters.
Edit: there will be heavy topics in later chapters
