Power Of the Sun in One Piece

What if Luffy didn’t eat the rubber rubber fruit? But instead has eaten something much more dangerous? *I don’t own one piece, it belongs to Oda-Sensei* *There are also pieces or things that are owned by WOTC, they own it, I just want to use it in the story to have more of a flavor for the story. (For all of you PC’s, you know what I’m talking about)
