Buba's final moments in general. He got fed up with how Bazoo treats his subordinates and how underhanded Ahames is, so he decided that he's retiring, and he knew that for Bazoo, retirement means death... but he gets to choose his method of dying, damn it! First he uses his special technique to apparently kill Shima, but turns out that it would just break the curse that makes her sound like a man all the time, to trigger her Heel-Face Turn. Then he challenges Tsurugi in a dramatic battle over the sunset, knowing that he may lose and die (the latter happens), something that's so iconic that it appears in one of the clip shows in Gaoranger vs Super Sentai and is considered the definitive losing/dying beautifully in Hikonin Sentai Akibaranger. This wins him the respect of the Changemen as Tsurugi's Worthy Opponent to the very end and gets him a proper burial in Earth.
