Syn Shenron

Syn Shenron is the one-star shadow dragon and the seventh and last one to be taken down by Goku. He is, by far, the most powerful of all the Shadow Dragons and the most arrogant and selfish one of all. The main reason why he is the most powerful is because he was born from the wish to revive most of the victims who were killed by Frieza and his henchmen on Planet Namek moments before it exploded and moments before they were teleported to Earth. He even has the power to absorb the Dragon Balls thus transforming himself into Omega Shenron.
