Handling of Villains Competing for Overall Power
I would personally like to talk about two groups and do a comparison of villains competing for power within the whole season. These groups are the Vyram and later the enemy factions in Boukenger. Let's see how they operate:
The Negative Syndicate are another. Unlike the Vyram, these guys were not really dramatic and they were multiple villain factions that competed for power, rather than an organization with no formal leader. They did team up sometimes, only to keep betraying each other. So they're basically "toned down" and somewhat comedic. At the same time, it was cool to see these factions exist in one season and go against each other most of the time. Apparently Ryuon and Gaja are tributes to Radiguet and Ryuon but far less bad-ass and sadistic. I find Gaja somewhat stiff for a psychic villain compared to Tranza who really kicked ass. Ryuon well, he was really mean and like Radiguet, he was just plain sadistic. The Dark Shadow, I felt that while Yaiba was a darker Gure having a past with Inou Masumi, Shizuka was in fact what I felt to be a parody of Maria and was really not dramatic. The Questers were really cool and nasty, and were probably taking tribute to Ramu and Gogu but far more bad-ass. How they battled the Boukengers and how they all collapsed was pretty much well-written that perhaps, some old Sentai writers were involved.
