User blog comment:Kaido King of the Beasts/Baseless Predictions/@comment-24799733-20140519161235

Blackbeard just took a fruit and ate it after Whitebeard died and his powers transferred to another fruit. He can take it because his "body is different" and that's it, no overthinking.

Big Mom ate the hunger fruit allowing her to eat anything and well... that's all...
