Lokar the Terrible (大サタン, Dai Satan, "Dai-Satan") is a villain who is originally from Mighty Morphin Power Rangers. He is an ethereal demonic head and the ultimate evil of the Seven Guardians of Light/Dinozords. Eventually, Lokar's Tower was used to summon him to the moon of Endor so that he could upgrade the Gorax's power to defeat Dino Megazord and Godzillazord. However, after the Power Rangers completed a ceremony to restore the ultimate form of the Seven Guardians of Light, the Gorax was destroyed by Dino Megadzillazord and Lokar was driven back to Tana by Dino Ultrazord.
In Marvel VS Super Sentai, Dai-Satan was referenced in the Zyuranger tribute chapter, with Lord Drakkon mentioning to have drawn upon his power to reforge the Hellfriede and create an autopilot program for Dora Telos, and again in the GoRenger tribute chapter when Aka Red alludes to Iron Majin’s potential to make even Dai-Satan shudder in terror.
