Super Saiyan Blue Saga
One Day Dr. Gero used every android made by him, put a blue ingredient in it and fused it with the black star Dragonballs and then it became known as Super Shenron. Relentless this thing was while blasting planets. No one could stop him. Not even the Saiyans themselves! All of the saiyans were dead except for Goku. As Super Shenron was using his final move, the Climatic Flash (which has the power of 15 final flashes,) a blood stream of Super Shenron was blown out of him and this blue substance flowed through the Climatic flash and went into Goku. Then, the climatic flash surrounded Goku and it was absorbed in Goku to make the blue haired super saiyan blue! This relentless super saiyan blue fought Super Shenron limb from limb! But that was not enough to kill Super Shenron. Goku tried the super kamehameha wave but Super Shenron dodged it. Goku had to find the dragonballs for help, but he soon realized that they were absorbed by Super Shenron. Desperate Goku had no choice but to use most of his energy to use another super kamehameha to Super Shenron's stomach. Lukily it blew a hole into Super Shenron and not only killed this sinister, and the dragonballs came out as well!
