Come on guys. Do you really believe that the Rubberman who used his conductor ability in the plot before gonna manipulate lightning now? That would be One Piece's biggest fail.

It is not lightning, it is impact graphics. We have seen them before many times from CP9 saga till now.

It's pretty obvious to me that Luffy has special names for his aerial attacks. Gomu Gomu no Storm is the aerial version of Gatling Gun and in exactly a same way Thor Elephant Gun is the aerial version of Elephant Gun.
