Imagine if Andy watched Haim Saban’s Power Rangers Dino Charge/Dino Super Charge (adapted from Saburo Hatte’s Ryouranger ), which came out 9 years after this. She no doubt would expect, as I did, for Keeper to bond the Aqua (rather than the Purple) Energem to the Plesio Zord. Keeper was an extraterrestrial, and he was the Rangers’ mentor in this season, as was the scientist Ms. Kendall Morgan. Aqua is Latin for “water”, and Plesiosaurus was an aquatic reptile.
Maybe he misread the 4 as a -1.
