Daimaou
From Power Rangers Universe
Daimaou is a 1,200-year old Youkai who took over as the new Youkai Army Corps leader, having his son Gasha Skull set up preparation for hiscoming into the human world by gathering children's souls to open the Demon-Seal Gate that confined Daimaou at bay, then gathering the souls of every human in the airborn district to speed-up the process.
However, though he was revived by his son, Daimaou intentionally sacrified him for his own plan. His base of operations was a giant flying Skeleton Castle with wing-like ears. He later declared the Time of Darkness, creating Daradara to aid him to drown the world in darkness before Daradara was destroyed.
After his brother and sister were killed, Daimaou was the only Youkai left to deal with the Kakurangers. However, Daimaou, being the embodiment of all evil and couldn't be destroyed or his influence would spread worldwide. In the finale, when he grew giant, the Three God Generals and Ninjaman used their powers to shrink him, allowing the Kakurangers to seal him back into the cave where the other Youkai are/were entombed.
