Raijin is a humanoid alien from the Ningu, a species of extraterrestrial beings beyond the stars. Due to a dying star near their planet, many of the inhabitants had to escape using space pods with coordinates to a thriving planet called "Earth". Raijin was one of the youngest members on the route to Earth due to his immeasurable potential as an alien warrior. Many of the weaker members of his races died when the star exploded because only the strongest could survive. His mother and father taught him differently than a lot of the other alien parents. They taught him to be a warrior with a heart for others, even if it meant he would hide his true intentions under a facade. But alas, they died due to a run-in with the government and All For One coming to an agreement that the aliens were dangerous and decided to eradicate them in an all-out war. Once the war ended, All For One left Raijin alive and wanted to find a way to steal his power. Unfortunately for him, Raijin was a warrior. He better Knuckle Up!
