1. ULTRAMAN Episode 23 

It tells the story of an astronaut who becomes stranded in outer space due to a technical failure. Because the government does not want the incident to be known to the public, it is ultimately covered up. While drifting in space, the astronaut’s body suddenly evolves into a monster. After transforming, he returns to Earth seeking revenge against humanity.

This episode is considered tragic because it highlights how humans can betray one another and treat others as if they are nothing.
