@Captain:
Am I the only one not terribly convinced Blackbeard is "invincible" now?! Whitebeard's DF power has hardly impressive to begin with. Because it worked so well on….
Er....
....
....
Well, it wrecked stuff, right? Oh, look, there's Akainu! ...With no visible injuries...
...
After Whitebeard's furious revenge attack. Huh...
Wow, this quake power sucks ass.
Well… actually if you think about it, it does give mild concussions.
That's serious business. Repeated concussions in the long run can lead to a decrease in cognition and basic thought process, so it's not very healthy to be exposed to such a terrible power.
So yeah, pretty much the threat of a gradual IQ drop over repeated encounters makes the Gura Gura the ultimate in intimidation warfare. BB could hold the world ransom for 1 million cherry pies.
Clearly you know nothing of Wun pEese and it's ultimate villain.
