* KeepCirculatingTheTapes: In the wake of ShoutFactory's announcement that they will not proceed to release the last few episodes of the show on DVD due to mediocre sales.
* TheOtherDarrin: This trope was not kind to the Swordbot Brothers. Magician, Fistbot, Spitbot, Minotaurbot, Wolfbot, Amphibidor also. Played around with when Zelton turned into Graybot and Metalbot.
** Once, the Swordbot Brothers even ''switched'' voice actors from the previous appearance. But it seems they never got the same VA twice, and they kept getting ''prominent'' appearances (rather than the standard "hanging out in the background in Grimlord's lair sequences 'til it's your turn as MonsterOfTheWeek" situation.) The last [[RichardEpcar voice actor]] ended up [[TalkingToHimself playing both characters]].
* TheOtherMarty: Jason David Frank was originally set to play Adam Steele in the unaired ''Cybertron'' pilot. A second pilot was also made which featured Professor Hart being played by a Caucasian. Brad Hawkins was cast as Rocky the White Ranger on Power Rangers. Saban realized that replacing Frank on Power Rangers was too risky so Frank returned to Power Rangers as Tommy in the role of the White Ranger and Hawkins stepped into the role renamed Ryan Steele. The name Rocky ended up being reused for for the second Red Ranger on Power Rangers.
* PropRecycling: The suits used for the battle grid fights were based on the spandex suits used in ''MMPR'', notably using the Red Ranger helmet mold from ''MMPR'' retooled/repainted to remove the dino details and to look closer to the trooper suits.
* RecycledScript: Not only the underground lab raid, but the brief OncePerEpisode sequence of a giant floating head thingy that would attack Ryan, only for his {{super robot}} to come and shoot it down throughout Season 2. There's no explanation given as to where either of these come from or why they're not used for more than this sequence.
* ShesAManInJapan: Despera. Dress and all. [[http://metalheroes.wikia.com/wiki/Priest_Poe Seriously]].
* WhatCouldHaveBeen: Saban originally conceived the show as a vehicle for [[Series/MightyMorphinPowerRangers Jason David Frank]]. However, the [[EnsembleDarkhorse runaway popularity]] of his ''Franchise/PowerRangers'' character Tommy led to their keeping him on ''MMPR'' and recasting the role in ''VRT''. Jamie Kennedy also had an early role.
** The ''Cybertron'' pilot also shows that the series was originally intended to be a stand-alone adaptation of ''Metalder''. It was only after Jason David Frank was replaced by Brad Hawkins that the series was revamped into a team show and the ''Spielban'' footage was brought in for the two additional main characters (since Metalder was a lone hero, whereas Spielban had a costumed female sidekick). By that point, Saban was also using footage from two different ''Franchise/SuperSentai'' series for ''MMPR'' (''Zyuranger'' and ''Dairanger'').
** The original seven minute pilot depicted Tao being aware of the Trooper's identities.
