As Altman representing justice, why did Astra steal Altman's key?

In Leo Altman's TV, Leo Altman once fought against the Otto brothers on the grounds that the fake Astra Altman stole the Otto key from the country of light. This is a very serious problem, because the Otto key is like the power device of the country of light. Once the country of light loses the Otto key, terrible things will happen.

After seven days, the Congress of Light deviated from its orbit and hit the earth, so both planets would be destroyed, so the Altman brothers chased the fake Astra Altman all the way to the earth. Because Leo Altman didn't know the truth, he fought with the Otto brothers to protect his younger brother.

In fact, this Otto key not only ensures the normal operation of the country of light, but also contains great power. The secret is mentioned in Altman story0, and the Otto key itself does not exist, because Babar people have been hunting Otto soldiers, and after obtaining the souls of these Otto soldiers, they generated this Otto key.

In other words, this Otto key has a very special significance for Altman. The strength of their comrades who died in battle is gathered here. Only one original Altman survived in Altman Story 0, that is, Gao Lian Altman, but in the end, Gao Lian Altman also lost his strength.

After Gao Laian Altman lost his strength, he was willing to be a grave keeper and accompany his former comrades-in-arms, while other Altmen in the Showa series did not die and survived. And formed the later Otto Guard, so this Otto key contains the soul of the former soldier Altman.

These ultramen fought side by side with the Otto brothers and gave them a lot. Otto's keys with their souls naturally can't make her have problems, so after the fake Altman stole them, the Otto brothers chased them all the way, even if the opponent was Altman, and they were merciless. If the King of Otto did not appear in time, the Otto brothers would join hands to fight Leo Altman, and Leo Altman would not be their opponent, even mortal kombat.
