'The Batwoman' (1968) aka 'La Mujer Murcielago'. René Cardona.

No slouch when it comes to creating vastly entertaining psychotronic celluloid, René Cordona's Acalpulco-set sizzler 'The Batwoman' is a batso bonkers B-Movie marvel. Generously packed with more voluptuously pulse-pounding thrills than Batwoman's agreeably eye-poppingly bodacious bikini! The singularly strange serial murders of popular wrestlers is linked to the inventively insane, pseudo scientific Sci-fi machinations of plainly psychotic Dr. Williams (Roberto Cañedo). 

The exotic sun splashed locations are certainly no less easy on the eye than vivacious star, Maura Monti as the luminously long-legged Luchador Batwoman. Successfully maintaining her secret identity, Batwoman demonstratively dominates wrestling rings and nefarious crime syndicates with equal ferocity! With a maniacal scientist's inexplicable yen to create a murderous Merman army, fiesty bouts of Female wrestling, and one of the slinkiest crime fighters of all time, Batwoman deliriously delivers the gonzo goods, baby! Midnight movie maestro, Cardona's fabulously far out fighting femme flick is a must-see for fans of 'Kriminal', 'Danger Diabolik', and, Jess Franco's beguilingly outre female fronted spy shenanigans!
