|This article is about a/an villain in Ninja Sentai Kakuranger.|
Prof. Yugami (ユガミ博士 Yugami-hakase, Prof. Warp): A Youkai scientist who created replicas of Youkai monsters from kidnapped children for Tengu. After Tengu's defeat, Yugami came under the services of Junior, providing the Youkai prince with mechanical weapons and armor for the other Youkai serving him. He appeared to cheer Gasha Skull on during the final stages of their plan until he was horrified to see his master destroyed before he himself was killed when a piece of the Demon Sealing Door shattered by Super Kakure Daishogun fell on him, crushing his body.
Though unseen, Yugami's spirit presumably emerged within the Seal Door along with all the other defeated Youkai, after their master Daimaou was finally contained there by the Kakurangers. Reeling that they were now powerless in captivity, the Youkai all vowed that they would one day be reborn and regain their power, cursing humanity.
He was portrayed by Noboru Akima
