There is a strong bond between Ultraman and humans, and this bond is not established overnight, but gradually accumulated after a long period of mutual trust. Although there will be a little episode in the middle, there are many humans who covet ultraman's power, but in the end they are all successfully resolved.
Although Ultraman has great powers, but far from his hometown, to the earth, his own energy is limited, in the process of fighting monsters, will also be consumed, causing the color timer on the chest to turn red. Ultraman has many ways to replenish energy on Earth, one of which is human power. So, given Ultraman power, does humanity need to turn into light?
In most cases, the answer will be: yes. Indeed, we have seen many situations that require human beings to become.
For example, when Diga Ultraman vs. Gatanjae, due to the rapid energy consumption, it turned into a stone statue and sank to the bottom of the sea. At this time, it is the whole human being that turns into light, giving Diga Ultraman the power to fight with Diga. It is precisely because there are so many human lights that Diga has become a shining Diga, several times more powerful than the original, destroying Gatanjae in one fell swoop and returning the earth to light.
For example, when Dyna Ultraman vs. Queen Monera, in a life-and-death crisis, the children holding Digimon Ultraman soft glue encourage everyone to cheer up so that they can shine. Dr. Lu Ruyue believed in him, and gradually, the children emitted light, and everyone also emitted light, and so did Dr. Lu Ruyue, and everyone's light converged into a giant of light. It was humanity that once again became the light that saved this crisis.
However, not all of the ultraman powers are given to become light, and there are some situations where they do not need to become light.
For example, in the time of Theliga Ultraman vs Megaloje, in order to pay tribute to Diga Ultraman, all humans are also arranged to replenish the energy of the Light Giant at the end. However, instead of turning into light like Diga Ultraman, human beings are all turned into light, but human cheers and shouts make Ultraman full of power again. When Ultraman hears these sounds, he rekindles the fighting power.
Not only Teliga Ultraman, in the previous Ultraman series, there have also been Ultraman who heard humans cheering and shouting and full of strength, such as Dana Ultraman, or the Queen of Monera, in addition to the energy given to him by Diga Ultraman, he saw the picture of human beings fighting desperately in the past, the sound of humans cheering for him, so as to get back up again.
Therefore, humans give Ultraman power, and do not need to turn into light every time, as long as the heart supports Ultraman and cheers for Ultraman, Ultraman will hear, this is the bondage.
