This cube craft paper model is the Nightmare Luffy, based on the Anime / manga series One Piece, this paper toy was designed by blackignus. Nightmare Luffy was Luffy's form after he was greatly powered up by one hundred shadows implanted into him. With Luffy's strong spirit, he was able to contain one hundred shadows within him when most normal people could only contain two or three. In this form, Luffy was several times bigger than his normal self and his skin turned completely blue. He was roughly the same size as Moriah and his body was similar to Chopper in Heavy Point. Luffy also talked differently, losing his usual carefree tone and instead speaking with a grim seriousness.
The fruit's powers have also been used outside of Moriah's own will by some of Moriah's victims. They learned how to harness the fruit's ability to make shadows tangible for their own benefit against Moriah himself.Over the years, while trying desperately to recover their own shadows, they learned that they could capture shadows that had been purified from Moriah's zombie minions. They could then put the captured shadows into themselves and gain the abilities of the shadow for a short period of time. Using this knowledge, they were able to imbue Luffy with a hundred shadows and turn him into Nightmare Luffy.
