Otto's father's father is Rhett Altman, and the two big horns are obvious. No wonder Otto's father also has two horns. It is said that Rhett Altman was one of the most powerful Otto warriors in the country of light at that time (the leader of the country of light was another person at that time). He married a woman of the same race and gave birth to Otto's father.
Maybe you don't know, in fact, Otto's father's real name is Kane, and Otto's mother is Mary. The reason for taking such a foreign name is that Yuangu wants to be in line with international standards and hopes that his company will become stronger and stronger in the world.
It is worth mentioning that it was only tens of thousands of years ago that Otto's father became the head of the country of light. At that time, the people of Ampala launched a war of aggression. Because of his outstanding performance in the war, Otto's father was elected as the head of the Committee and the Cosmic Guard, which continues to this day.
Of course, Altman basically won't die unless he dies abnormally, so Altman's father can always be the first person in the bright country. Although Ultranman Taro is called a prince, I'm afraid he can only be a prince forever.
