Well this is interesting...

I like this alternate version of the dynamic between the Marines and straw hats you depicted. It's a pretty creative spin.

I am really curious why this Smoker fights Luffy. My guess is that she just wants to.

Because when two heroes from different sources meet up, they have to fight. Have you never read comic books?

or played crossover games.

so? anyone got a idea of story to tell?

Well, since they seem to be going for a team up, if anyone is up to it, i'd say a story about surprising team up, either with another player or a NPC. sometimes the circumstances just call for it.

Hey! is'nt that Gary the crescent moon?

Given how the entire World Government is corrupt I'd say it's pretty likely that Smoker chasing Luffy will justify itself. I mean given how much a party not caring can wreck any and every plan and scheme, kinda like having a team of leaf blowers marching down demolishing their brittle sand castles they built up that let them control most everything will tick off more then a few people.

My guess is it'll be something along the lines of "Well, I'm real sorry about this, but you did just bring down the gallows, and that was a rather important structure."

"You're right, and I am sorry about that, but it wasn't me that rolled a Nat 1 three times in a row. Anyhow, don't really have time to fight, we need to get to the ship before this storm wrecks her!"
