Asl's secret

Proluge(explanation)

Ok first of we have the one and only fire fist ace

So in this story ace will have the power to create illusions using his power. So like ace will also be able to give nightmares to his enemies making them go unconscious. Ace also uses this method to torture his enemies sometimes. I got this idea from seraph of the end based on the character Norito Goshi.

This guy on top.

Ace needs that pipe Norito Goshi uses in order to make those illusions but when the brothers were younger all of them gave their weapon of choice to Garp because they were to powerful apparently. However during the war Garp decided to give them back and act like good grandfather. He never told the whitebeard pirates because he was afraid they would think of him as a monster.

That is how the pipe looks like.

Ok next is sabo

So in my mind I think sabo is best suited as a sniper. But I don't want the bullets he shoots to come out as ordinary bullets. So again I am gonna borrow some inspiration from seraph of the end which I sadly do not own forgot to mention earlier. I want sabo's sniper rifle to be like Shinya Hiragi.

When he shoots a bullet there will be like a tiger. I am getting irked just trying to explain so just watch the video down below

That is how the sniper rifle will look like

Ok now it's luffy's turn

I think luffy will be best suited for close combat therefore the best weapon he should use would be Guren Ichinose's sword(who is from seraph of the end)
