The Night Dr. Loveless Died - S3-E4
Trivia: Dr. Loveless' uncle's name, "Liebknicht", is, aside from the addition of the letter "k", German for "Loveless".
Trivia: The unused script of the final fight between Ultraman and Zetton was entirely different, as it shows Zetton ripping apart Ultraman's colour timer. In the end, Zoffy will save Ultraman and defeat Zetton. However, the writing team decided not to use it because it was deemed too violent, and it portrayed Ultraman, the main hero, being cut. This alternate ending can also be seen in the game Ultraman Fighting Evolution 3 during the Ultraman vs Zetton mission.
