Meanwhile, in Loguetown, a twenty two year old guy who kind of looks a fair bit younger than that just killed and looted four guys with a kitchen knife, and there's a bunch of guys fighting on the roof of the building they died in. Fun times, friends! Just not as flashy as what Xerxes is trying to do. You'd think electrical fire would work as a weapon against a Logia fruit, but no, apparently not.

Frankly, fire (or energy in general.) doesn't seem to affect the Smoke Logia - as opposed to say Enel or Crocodile's weakneses to Rubber and Dampness, respectively.

As seen by Smoker and Ace fighting to a standstill.

Though, I'd reckon with my comic-book science brain, that freeze-moves would work against Johnny.
