Alien Babalou is a race of alien creatures originally featured in the TV series, Ultraman Leo. He appeared in episodes 37 and 38. Self proclaimed as the "Dark Ruler of the Universe," Alien Babalou was a cunning, trickster alien with a personal vendetta against the Ultramen and came up with an evil plan to destroy them. First, he captured and froze Leo’s brother Astra to steal his identity and then used his chain to topple the Ultra Tower in the Land of Light. Inside the ruined tower, Babalou entered the ruins and stole the Ultra Key, an object that keeps the Land of Light in orbit around were its dead sun once stood.
