medjed (mythology)
In Egyptian mythology, Medjed is a very obscure ancient Egyptian god who seems to be the figure wearing what appears to be a sheet over his head with only his eyes and feet poking through on Sheet 76 of the Greenfield Papyrus. He may or may not feed on hearts. Only mentioned in Spell 17 of the Book of the Dead, his name means "The Smiter" and he can apparently shoot eye beams. He also appears to be related in some way to Osiris.
Despite being otherwise extremely obscure, he gained a new lease in godhood as a meme in Japan due to his rather goofy-looking depiction on the papyrus, resembling some sort of mascot character.
"Medjed" can also refer to a species of elephantfish which, according to mythology, ate Osiris' penis after the latter got killed, dismembered and his body parts scattered by Set. Osiris was eventually reassembled and, despite lacking his penis, he was still able to produce Horus.
