Kali Ma! Mola Ram might just be the most bombastic of every cult leader on this list. In his search for the Sankara Stones needed to bring forth the reign of Kali, this villain of Indiana Jones and the Temple of Doom makes slaves of an entire village’s children so they can do his bidding and mine for his precious stones all night and day. He’s also into brainwashing, magic potions, feeding people to crocodiles, funky headgear, and ripping the beating heart out of his human sacrifice so he can hold it in the air as it bursts into flames. He’s probably the cult leader I’d least want to screw with. I like my heart in my chest, thank you.
