Oh right, Blackbeard can get hit by physical attacks.. totally forgot about that o.O
I kinda figured a "Darkness" fruit would be in the same category as Admiral Kizaru's "Light" fruit, seeing as his body is basically "made of light"
But Blackbeard can make "black holes" can't he? is he then able to absorb Kizaru's "light"? Would be interesting to see a fight between those two, Light vs Darkness :P
