When questioned by Clark Kent about her nickname of "Lo-Lo", Lois Lane replies that at the time of Titano's launch she was eight years old. As twenty years have passed since the launch, this makes her twenty-eight, marking one of the few times in the DC Animated Universe a character's actual age is ever confirmed.
Only appearance in the series of Lois Lane's younger sister, Lucy. Unlike other Superman series where we see Lucy Lane as an adult, we only get to see Lucy as a young child in this series.
The name of the toy monkey that calms Titano is Beppo. In the Superman comics, Beppo was the name of "Super-Monkey", a monkey from Krypton that Jor-El sent into space on a test mission and later found his way to Earth where he gained the same powers as Superman. Beppo joined Krypto the Super-Dog, Streaky the Super-Cat and Comet the Super-Horse to form the "Legion of Super Pets" in Adventure Comics in the 60's.
