For the concept of the ultimate life form, I believe everyone also understands that Round Valley means that they cannot die, and the AbuSolut people led by Tartaros are like this. In fact, in Ultraman, only one person is in the same situation as them, can you guess who it is?
When Round Valley said that the Absoluts were the ultimate living beings, many people were still wondering what caused them to become like this, but all absoluts were like this. However, in the special episode of the third season, Round Valley finally revealed the answer, and it turned out that the planet they lived on was really quite special, more special than the Star of Otter. Tartaros said their planet also has something similar to a plasma spark tower, and this kind of thing provides them with a steady stream of energy support.
With this energy, they can not only become very strong, but also have an immortal body. But now that their planet is out of control, it can be said that it is not far from extinction, which is why they want to occupy the Land of Light, after all, they also need to survive. Speaking of which, is there one thing that everyone has considered? Tartaros brought Beria and Torregia to his own planet and replenished them with the energy of his own planet, and since then, the strength of these two people has increased, does not mean that they also have an immortal body? Round Valley means that the Absoluts did not die because they had a special heart under the special light of the planet, and in fact, in Ultraman, only one person also had this special heart.
Speaking of this, some people may think of those Ultraman masters, and even think that this Ultraman with a special heart must be in the mysterious four O'o'or, in fact, this is not the case. This Ultraman is just an ordinary hero. And he's from the Land of Light, and yes, he's Tyro Ultraman. It is reasonable to say that all ultramans in the Land of Light do not have this special heart, why only Tyro has it? In fact, it is still a puzzle until now. The encyclopedia has been clearly marked, this thing is not made up, so it is no wonder that Tyro Ultraman always can't die.
Of course, there may also be a reason that the birth of Ultraman Tyro is different from other heroes, everyone has watched the TV series that year, remember how he was born in the first episode? To be honest, it feels a bit like the results of scientific research. However, even if Tyro can't die, it doesn't mean much, after all, his strength is not very strong, and he can count as something in the entire universe. Of course, it doesn't matter if Ultraman has this special heart, which righteous Ultraman have you ever seen die completely? Now they're all living well.
Of course, the highest level of life in Ultraman's world is not the ultimate life form, do you remember a monster named Leaf Rot? He is a completely living body, how can you say such a character can afford it?
