Ultraman has “Color Timer” on the chest.
The timer shows the limit of Ultraman’s activity on the earth.
Ultraman’s energy source is solar energy.
When solar energy decreases, his Color Timer changes blue to red, and it starts to blink and beep.
The time limit is 3 minutes.
According to the narration, if lighting of the Color Timer should go out, Ultraman would lose the power to stand up ever again.
The narration by Koji Ishizaka goes on, “Ultraman, hang in! You have only a little time left!”
That made us breathless in watching the battle between Ultraman and Kaijyu.
Where did the idea to set a limit on the activity of Ultraman come from?
There are several different stories.
One is the staff thought it was uninteresting to make Ultraman so much invincible without any weakness.
Another is, as Tokusatsu (SFX) is so costly, it was an attempt to make the Tokusatsu part of each episode as short as possible.
It is also said it was Eiji Tsuburaya who advised to make Ultraman have the Color Timer.
The 3 minutes’ limit was said to be adopted according to boxing matches or instant noodles (Ramen) which began to be popular in those days as they could be cooked for 3 minutes.
