The three remaining Beastnoids are also rebuilt into stronger forms.

* ThemeTuneCameo: Hikaru is playing the Bioman opening theme on the flute while walking towards the enemies in episode 15.

* MakeMyMonsterGrow: Absent. Gear has five human-sized monsters called the Junoids, which they use over and over and a different giant mecha in each episode. As this prevented the giant monsters from getting much screentime (and thus Toei from getting much of a return on investment), this approach was largely unique to ''Bioman'' until future seasons that avert it as well, such as ''Series/TokusouSentaiDekaranger'' and ''Series/TokumeiSentaiGo-Busters''.

* RealLifeWritesThePlot: Yuki Yajima, the actress who played the first Yellow Four, left due to some shady circumstances that even today aren't quite clear. Some claim she had a falling out with J.A.C., the stuntworkers union that Sentai hired most of its early actors from, while fellow cast members believe she eloped with someone. Either way, the actress hasn't been heard from since then.
