In fact, let's not say that many of the Ultramans we think of are actually not Otter warriors, and there are still many of them. For example, the following 13 heroes, their situation is like this, don't make a mistake.
Everyone has seen Digimon Ultraman, and there are five ultra-ancient heroes, in addition to Diga and the evil Diga, there are three of them are Camilla, Hitra, and Durham. Usually everyone calls them Ultraman, right? In fact, this is not the case, and Round Valley has already said about this matter. They were not Otter warriors, but so-called giants of light, and round valley was set for them in this way. If you really think of them as Ultraman, it really doesn't fit.
Speaking of which, everyone should be able to think of the drama "Ultraman Of terriga", right? There are also five heroes who appear in the same situation as Diga and the others. Round Valley said that they were super-ancient giants of light, to put it bluntly, it was different from the heroes of the Land of Light, Triga, Dark Triga, plus Carmira, Hitram and Dagon, Round Valley's routine is basically exactly the same. Of course, then again, everyone tends to treat them as Ultraman, and it is more appropriate to call them Triga Ultraman, but it is not good to call him The Giant of Light of Triga.
In addition to the above ten heroes, there is another one who cannot be called Ultraman, and he is Astra. His brother Leo was often called Ultraman, which was no problem, and So was Round Valley. However, it would not work with Astra, and Round Valley was reluctant to add the word Ultraman to the back of his name, and he did not know what was going on. In fact, to be honest, Round Valley set the heroes of the Land of Light as Ultraman, while the heroes of other planets have their own titles, but they look quite similar, so they are often described by everyone with the three words ultraman.
There is also the 12th hero, and his situation is also like this, that is, Dark Zaki. His image is indeed similar to Noah Ultraman, but everyone must know that he is a robot created by the cosmic people, and he cannot be called Ultraman at all. Of course, did you find a problem? The so-called dark warriors arranged by Round Valley in the play actually do not have the three words Ultraman after the name, dark Zaki is like this, dark Obu, dark Cyro, dark Ax and other people are like this, who makes them villains.
And of course there's the 13th, who isn't Ultraman at all, but a monster that later became Ultraman because he gained a powerful power. After fighting monsters to save the Kingdom of Light, he became a member of the Kingdom of Light after being accepted by the Father of Otter, and he was the legendary Star Ultraman. According to the setting, he is now a member of the Cosmic Guard and has a good relationship with Ultraman Monbius, but to be honest, he is not Ultraman at all.
