Tengu (The Mysterious Murasame Castle)
These
air demon ninjas appear outside various castles the Daimyo lords took over following an alien Murasame's influence possessing them, facing Takamaru on his journey to stop them from conquering the feudal Japan. In Infinite Beyond, quite different compared to a
existing Smash Dungeon enemy (which is more of series-original than basing on a specific game;
think about a Metal Gear/MK case), after being summoned, a Tengu demon will perform a pose with it's symbolic fatsia leaf and surround itself inside a whirlwind, quickly traveling around the stage and firing out smaller gusts of tornadoes from it's fans which slightly pushes fighters away when hit (8%), able to damage opponents by tackling right into them (14%).
Whenever it drops back to the ground, a Tengu demon will perform poses for a brief time, durlng which fighters can try to attack it (as like in the original Famicom Disk System game, it is invulnerable to their attacks while flying in a whirlwind and often tends to hold still in between). It can fly up to five times before disappearing off.
