These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Choushinsei Flashman
Complete Monster: Ra Deus and Lee Keflen. Ra Deus is like Bazoo but if Bazoo is a Planet Eater, Ra Deus is an asshole with a messiah complex who will do anything, including destroying countless planets, just so he can become the ultimate being. Lee Keflen, his main scientist, will sacrifice anything for his experiment.
Ensemble Darkhorse: For some reason, Sara is quite popular amongst the audience. It helps that her Flash Star outfit are pretty revealing for the standards of Super Sentai at that time (Panty Shot and revealing her chest above her boobs, although they're not that big), plus being eventually revealed as Tokimura's daughter, giving her most of the drama and nearly stole the show from Jin in the last episodes.
Meta Mecha: Great Titan can be considered, that Titan Boy enter in the superior part from Titan Carrier to get this formation.
