Lt. Koryu

Lieutenant Koryu was a lieutenant in the Red Ribbon Army, but was discharged by General Tao([link]). He helped Goku eliminate the Red Ribbon Army to get revenge on Tao. Goku had no idea. He is also one of Bardock's (Goku's father, [link]) friends who was thought to be dead. Here you see him in Super Saiyan 4 form. He wiped out some of the "Cold Shoulder Force", Frieza's army. He is supposedly a regular man, but has secretly aided Goku for many years. (Ever since he was about Pan's age) Soon you will see more of his forms, as this post will be updated.
