* CounterpartComparison: The resemblance in both personality and appearance between the main antagonist of Episode 20 and [[WesternAnimation/StevenUniverse Lapis Lazuli]] is [[http://lemon-optimizer.tumblr.com/post/142921398820/i-found-her-she-is-not-lapis-lazuli almost uncanny!]] And to a much lesser extent, there's also someone there who [[http://lemon-optimizer.tumblr.com/post/142981628225/yup-sour-cream-is-also-in-fantaman-he-is-also resembles Sour Cream]], from the same show. Their names are Penny and Gorgo, respectively.
* EnsembleDarkhorse: Three guesses, no prize.
* HilariousInHindsight: Again, the aforementioned [[WesternAnimation/StevenUniverse Lapis Lazuli]] resemblance (whose name is Penny); they both have a water affinity.
* [[GermansLoveDavidHasselhoff Italians Love Fantaman]]: The 1966 anime of Golden Bat (named Fantaman in the italian dub) is remembered fondly by quite a few italian people who grew up in the 70's and 80's.
* JustHereForGodzilla: Yeah, many people watch Episode 20 just to see the [[WesternAnimation/StevenUniverse Lapis Lazuli]] [[AddedAlliterativeAppeal lookalike]] (Penny).
