Them why Roc Gun and Roc Gattling isn't a G3 attack? With Adv hakis exclusively?
Roc Gun is a bigger than normal fist:
That is an inflated fist. You can see because it looks like a smaller Elephant Gun. If it wasn't inflated, you wouldn't see Luffy's forearm inflated like this.
And we haven't seen Roc Gattling yet, but guaranteed it will look like this too
The gomu makes some sense because we know it was a big deal for them. I will bet on the darkness fruit because they had a talk with Saint Shanks
