When Glenn Masters was about 12 years old, his father, a rich hotel tycoon, thought that his son needed to learn about discipline, lest his son become a spoiled brat all of his life and try to leech onto the Master’s family fortune.
In order to do so, the elder Masters sent Glenn to Japan to train under his best friend, the mysterious amateur wrestler Gouken. At first, Glenn was very hesitant to learn from Gouken, wanting to go back to the United States, but later began to respect his master. He even enjoyed the company of Gouken's adopted son, Kaj, since he had a foil to finally pull pranks on, although this got Glenn into a lot of trouble. Kaj and Glenn would later become best friends and each other's principal rivals.
When Glenn was 23, Gouken decided that both of his pupils had grown up to be fine wrestlers and decided that their training was over and could now leave the dojo. Kaj decided to travel the world in order to continue his training, whereas Glenn was finally happy to be going back home to the United States after his years of straining his back for master Gouken and finally learning the meaning of humility. After coming home, Glenn competed in several amateur wrestling events, winning most of them. It did not take long for LPW to notice Glenn’s amateur background, and offered to train him in professional wrestling. Glenn took to it quickly and is now ready to compete like no one before him has.
