- The Danza: Megumi Mori as Megumi Misaki.
- Executive Meddling: Liveman was originally supposed to be a three-member team through to the end, until the producers realized it was the tenth Super Sentai show since the franchise's revival with Battle Fever J and they wanted to do something special. Thus, Black Bison and Green Sai were added to the team mid-series. This caused some plot holes with previous episodes (such as the fact that Yusuke was unaware of Tetsuya's existence, despite being acquainted with Takuji's other brother Takeshi in an earlier episode). But it also led directly to the introduction of the Live Boxer and Super Live Robo, the first Super Sentai Humongous Mecha to be formed from two smaller Humongous Mecha. A net positive, all in all.
- Meta Casting: When Liveman started, Daisuke Shima was an Idol Singer with a Hot-Blooded rebel image, and the character of Yuusuke was written to match. Later on, under the insistence of Shima himself, Yuusuke developed into a traditional leader.
- Name's the Same: Decades later, Kirby: Planet Robobot would feature a series of giant robots named Gigavolt, though those were simple minibosses while this series's Giga Volt would be a Climax Boss.
