Cofagrigus is a blue and yellow sarcophagus with red, menacing eyes and four ebony hands that appear to be shadows. A simply designed face is prominent on the "forehead" of the Pokémon. Its real face is covered up by parts that slide
out of the way when it is active. White, sharp fangs create a taunting smile and flamboyant patterns veil the coffin. The coffin is said to be made of gold.
Ancient legends once told Cofagrigus could eat nearby humans and turn their lifeless bodies into mummies; grave robbers who mistake them for normal coffins get this fate. Cofagrigus is said to have once been human but having forgotten its memories from when it was alive. They also enjoy eating gold nuggets. It lives in tombs and ruins.
