The first Super Sentai series to have women as members of the assistant "good forces" who help the heroes. It was also the first Sentai to present a creature who enlarges monsters after they are defeated (before that, the monsters could increase their size by themselves, or could call a giant robot to fight a second time).
Shiro Izumi (Oozora Yuuma) would later portray Burai (DragonRanger) in Kyoryu Sentai Zyuranger.
