Samurai Jack Reader X RWBY
(This is a male reader)
(Y/N) had a good life and lived in a peaceful kingdom. His father was the emperor of that kingdom. (Y/N)'s father told him about the tales of how he defeated the shape shifting master, Aku. When (Y/N) was 8 years old the village was attacked by Aku. (Y/N) and his mom were the only ones who escaped. (Y/N) went through 10 years of intense training and mastered just about every weapon and skill. When he was 18 he was given the magic sword that defeated Aku decades ago. When he faced off against Aku and made it to the final blow, Aku opened a portal in time and threw (Y/N) into the portal causing him to go about 25 billion years into the future and to Aku's mistake, it took him to a different planet.
This planet is called Remnant. Aku hasn't completely taken it over yet because of both the hunters and the creatures of Grimm. It is up to (Y/N) to help strike back against Aku and the Grimm while trying to get back to the past.
