Crisis on Infinite Earths: Part Two - S1-E9
Trivia: The version of Batman played by famous Bat-voice Kevin Conroy is a darker version of that from the graphic novel The Dark Knight Returns. The line "the world only makes sense when you force it to" is a version of a line from that comic (also used in Batman V Superman), also "Clark always said yes to anything with a badge or a flag." There are also elements from Batman Beyond, which first aired in 1999 (hence Earth-99), in which Conroy voiced an older Bruce Wayne mentoring a new Batman. The whole scene is full of nods to other versions - describing Kryptonite as "a little souvenir from the old hometown" is a Lex Luthor line from the original Superman movie, and him describing Superman as "strange visitor from another planet, with powers and abilities far beyond those of mortal men" comes from Superman serials from the 40s and 50s.
The Return of the Beast: Part 1 - S1-E1

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.
