Bake-Bi

Bake-Bi (lit. Monster Flame) is a fire youkai similar to Tsurube-Bi.

In the 1985 anime, Bake-Bi appears as a large ball of yellow flames that float several feet above the ground. Within the flames are what appears to be three skulls, the foremost one being the lowest, one behind and above to the right side and the last is at the very back to the left and above the other two.

Within the 2018 anime, Bake-Bi has three round orange heads, one infront of another, with round yellow eyes, small noses and no mouths. Their flames are magenta in color.
