@onemoment:
I call it. I'm predicting that Gekko has light powers.
Interesting guess, but I find it non-Oda-ish to have just recently introduced a Dark fruit and then to introduce a light fruit. More than likely, it'll be something completely unrelated like a weird paramecia that lets you blend into any environment like a chamelion and use the environment to attack! yeah! something like that!
how does that allow him to steal shadows… only oda knows ^_^
@Ivotas:
Unless of course the concept is somehow inspired by Toriyama´s Cell who already got stronger with consuming peasants. Then the shadow stealing concept could actually be a way to enhance the shadow thief.
But, aren't we kinda hoping that Brooke and the Old man will get their shadows back. When Cell took people's "energy", they were pretty much dead. I understand you are refering to the simple concept of taking shadows to enhance oneself, but I've been shying away from the theory that the shadow thief stores the shadows internally. Since this seems like a difficult way for the SHs to recover these stolen items if they're somehow stored internally by the user.
