Phanto

Phanto appeared in 1988 video game called Super Mario Bros. 2. Phantos are large, seemingly-living masks that can often be found guarding various treasures, although they most often guard keys. Their name appears to be a shortened form of the word "phantom", another word for ghost or specter. Originally, Phantos sported a very solemn demeanor in Yume Kōjō: Doki Doki Panic, while starting with Super Mario Bros. 2, it was given an evil grin.
