User blog:Coby413/New Attack

So at the end of chapter 691, Luffy is about to throw a dual Gear 3rd with Busoshoku haki punch.

I have a feeling that this is about to be a new attack. Luffy is pissed and if it was a simply bazooka or an elaphant gatling, i feel like it would be drawn at the end of the chapter. I feel like it will do damage to Caeser but not much. This fight has only begun.Any thoughts on what the new attack might be?
