User blog comment:Yeit/Gol D. Roger devil fruit???/@comment-1454981-20110227065033

if roger did have a devil fruit then it had to be the rock rock fruit(earth logia), it just makes sense. it was said that he was able to destroy armies and countries. and the only person to tie with him is whitebeard who can make EARTHquakes. so it kinda makes sense.
