#usopp the first time he lights himself on fire: WHAT THE FUCK WHAY THE FUCK WHAT THE HELL OH GOD OH F-

[camels-pen]

consider sanuso bodyswap where Sanji is of course "admiring" Usopp's body and Usopp is trying desperately to keep himself from getting worked up so that he doesn't light himself on fire.

Luffy and Chopper are not helping. They are in fact doing the opposite of helping. They've ramped up their pranks and are doing anything possible to get Usopp angry so that he combusts, freaks out, and then dives into the ocean to put himself out. They think it's hilarious.

Nami and Brook are Also not helping, since they're conspiring with Sanji to put on a fashion show with Usopp's body. Sanji called it "not wasting a precious opportunity to get him in something other than overalls". Usopp called it mutiny and he was gonna- dive into the ocean, holy fuck Sanji why is it so easy to catch fire?!

Best part about this is that Sanji assured him, several times, that his body doesn't get hurt by catching fire. Usopp still jumps into the ocean every time.

Robin pipes up at one point, asking if Sanji was immune to just his own flames or all flames. Sanji just kind of shrugs and said it depends. Franky, having just been leisurely watching all of this gets an idea. Would his Franky Fireball hurt Sanji's body or just give him more fire to work with?

He tries to coax Usopp into agreeing to test it out and, somehow, he manages it. Albeit, Usopp is all knocking knees and chattering teeth, a very odd sight from 'Sanji'. As part of the deal though, he can only shoot a fireball the size of his hand.

Usopp meant his small hand. The one Franky used for tinkering and fine detail work. He did not, however, clarify this.

So, when a fireball the size of Franky's big hand comes out, well. Usopp runs for his goddamn life.

It takes him a few moments- and the voices of his friends sounding distant and below him- to realize he hadn't, in fact, run to the men's quarters, but rather into the fucking sky.

And oooooh, boy he is gonna kill Sanji one of these days. Why was his body's first fucking instinct when running to go up, what the actual HELL-

Usopp lit himself on fire again.

He curses out Sanji as his Sky Walk fails in the same moment and he plummets towards the deck.
