What is the dark history of Severn Altman?

Although Saiwen Altman is the adopted son of Otto's father, he is still older and ranks third among the Otto brothers. The whole country of light has a lot of black history, that is, history that has not appeared in the plot. In fact, all Otto soldiers have an unknown history. Let me briefly talk about the black history of Severn Altman.

Perhaps many viewers don't know that Saiwen Altman was once held in the cosmic prison, which only appeared once in the plot, and was also the place where beria Altman was held. The reason why he was put into the cosmic prison was to help mankind destroy other races of mankind. Later, this incident was known by Guangming, which has seriously violated the regulations of Guangming, so it was put into the cosmic prison. The country of light has a rule not to participate in wars on other planets.

There is another unknown secret. There may be many viewers who don't know Ultraman Jack. He is the blue Altman of the country of light and the brother of Otto's father, but because he can't be the captain of the country of light, he has the idea of rebellion. After that, he left the country of light, established his own cosmic guard in the universe, and then began to attack the country of light. Severn Altman was also involved in the war, and it was he who defeated his father's brother Ultraman Jack.

For Severn Altman, he has experienced a lot. Presumably, most viewers don't know why Severn Altman has been staying on the earth. In fact, he is thinking about his girlfriend. Once, he and his girlfriend investigated monsters on the earth, but he was killed by monsters because his girlfriend was not strong enough, and then he has been guarding the earth.
