1 is a status symbol.
First of all, among all Altmans, only the Altman with a bright world outlook wears a cloak, and the rest of the Altman with an independent world outlook has no cloak. In the land of light, the cloak seems to represent identity. We can see that Altman wearing Otto cloak is basically in a high position in the country of light, just like the Otto brothers, because they are the first batch of Otto soldiers who came to guard the earth. It can be said that they are Altman soldiers who have returned from overseas experience and are also important members of the early Otto guards. Naturally, their status is self-evident. And the father of Otto, the king of Otto, etc. , are of high status. For example, young Altman like Beyonce Dream and Altman Galaxy have no cloak to wear. Except for the father of captain Otto, the cosmic guard, and the mother of captain Otto, the six Otto brothers all wore red cloaks, which looked very imposing and aura. As members of the Otto brothers, Eddie, Astra and Monbius have no cloaks. What is the reason?
2. It is an important weapon for Altman to fight monsters.
Some Altman's cloaks are just status symbols, but one Altman's cloak is different from them, and that is Leo Altman. Other Altman's cloaks may have been prepared in the Academic Affairs Office of the Kingdom of Light, but the cloak given by King Alto to Leo Altman is unique and can be turned into a weapon, which has played an irreplaceable role in the battle between Leo Altman and monsters.
Therefore, it is precisely because of these two reasons that Otto's cloak is not available to every Altman. After all, Otto's cloak doesn't mean anyone can have it.
