This pokemon papercraft is Cofagrigus (Desukarn), a Ghost-type Pokémon, based on the anime / game Pokemon, the paper model was created by javier. Cofagrigus evolves from Yamask starting at level 34. There are 33 parts on 8 sheets of paper.
Cofagrigus is a blue and yellow sarcophagus with red, menacing eyes, with four ebony hands that appear to be shadows. A simply designed face is prominent on the "forehead" of the Pokémon, which is similar to the mask that its pre-evolution carries. White, sharp fangs create a taunting smile and flamboyant patterns veil the coffin. The coffin is said to be made of gold.
Cofagrigus are rumored to eat humans, but are known to enjoy the taste of gold. Cofagrigus imitates an elegant coffin to lure in unsuspecting grave robbers and punish them. They live in tombs and ruins.
According to its Pokédex entry in Black, ancient legends once told Cofagrigus could eat nearby humans and turn their lifeless bodies into mummies. It also has the ability to form two pairs of arms. Its real face is covered up by parts that slide out of the way when it is active. [Source: Bulbapedia]
