Is Altman an alien or an earthling?

Many Altmen are aliens, except for a few Altmen, such as Heiping Sanjie Jiedi Dai Ya and Dana Gaya. Like the first generation of Saiwen, Jack Esterro, Leo, Astra, Adilian, as well as Aoki Wang Ao, Mumbius and Hikali, these are all aliens from the bright land in the M78 Nebula. Specifically, Baidu "Altman" can be used, and Du Niang will tell you in detail. As for why Altman came to the earth and became a human being, we can understand it from two aspects. If we must consider it from the perspective of the plot, then we can say that Altman can't keep the giant posture on the earth for a long time, at most for three minutes at a time, and there are reasons to hide his identity, so apart from destroying the enemy, Altman will not keep this giant form for a long time. However, if Altman wants to stay on the earth to defend the earth and fight side by side with the earth defense team (usually seven people), it must be easily accepted by the public in the play. So for Altman, it is the best choice to stay on the earth as an earthman. To understand Altman, you should know that Altman belongs to a super-evolved advanced creature and can easily become a human with various superpowers. Some Altman may choose to borrow the human body from the earth. If he is felt by an earthman's heroic behavior (such as crashing a plane into a monster), then he will blend in with this earthman, exist as this person at ordinary times, and become Altman at the critical moment, and so will the first generation Jack Esterro Hikali. Another Altman will directly become a human being living on the earth, and a prototype will appear at a critical moment. They look like ordinary people on earth, but they are all pure cosmic people, just like Edie Menbis of Seffrin Leo. Altman, who came to the earth from the M78 nebula, often regards the earth as his second hometown, although all of them are pure aliens. As for the understanding beyond the plot, it is necessary to talk about the appearance of aliens. When it comes to aliens, many people's intuitive impression is the negative image of blue face and fangs, short and ugly, small eyes in European and American blockbusters, or the monster image in Spielberg ET and other movies. As we all know, aliens can also look like humans and look exactly like humans. You can't see it with the naked eye unless you see the essence clearly. After reading the men in black, you should know that many aliens here look like humans. And Do Min Joon are called beasts. At first glance, they are just ordinary people. In fact, they are aliens. There are many similar examples. In short, aliens are not all ugly monster images, and aliens can be as handsome as animals and win the favor of women. Aliens can also be as burly and chic as Altman and become cosmic heroes in the eyes of children!
