In the whole vast universe, there is a higher civilized life than human beings on a certain planet, that is, the country of light. Once they had the same appearance and living habits as human beings, but because of the disappearance of the natural sun, the country of light fell into endless darkness. At this time, scientists in the country of light made an artificial sun with powerful light energy through unique minerals. Although the appearance of the artificial sun has brought light to the bright country, the "human" on this planet has mutated because of too much energy, and finally became the Otto soldiers we see.
With regard to the acquisition of light energy, what is mainly mentioned here is the Otto warrior who appeared in Heisei period. Here, take Gaia and Aguru Altman as examples. They were both born on the earth, and there are Otto warriors who appeared because of the light power of mountains and seas. And the way they prove that they are Warrior of Light is completely established.
For the cultivation of Ott genetic factors, here we mainly mention Emerald Altman. As the son of beria, at first, in order to gain the strength of Ott capsule, beria gave his Ott gene factor to K at the beginning of Fukui, and asked him to cultivate it with the technology of "nebula loading", which is the reason why today's G&D Altman was born. However, the cultivation of genetic factors is also one of the ways in which Altman was born.
