The show itself for being a self-parody. In-show, Kyousuke proves his love for Zonette by taking on the bad guys- and the Monster of the Week- unmorphed.
A CMOA for the series as well, on the special effects front: Episode 32 has Red Racer convincingly fighting that week's monster on top of a set of batteries on RV Robo's waist - impressive for a TV show in 1996.
Exhaus attempts to drop the Bowzock's base onto the Earth, only for it to be stopped and put back into orbit. You're probably expecting this to be a combined effort of all the team's mecha, a la Mobile Suit Gundam: Char's Counterattack, right? Nope! Turns out that it's Signalman and Sirender all by themselves!
