One Piece Skins

Luffy as Zac obvious enough with the stretching and bouncing, passive dont match up the best but oh well.

Zoro as Yasuo mainly I say him cause of his dashes and I figure the ult is a 3 sword attack sent flying as someone.

Usopp as Caitlyn? Umm Idk Usopp is known for ridicules range and her ult would be much like how Usopp finished off Mr. 4 maybe you could argue Jinx or something instead.

Sanji as Lee Sin obvious enough quick people with a devastating kick.

Nami as Janna both use the weather to fight and typically support others in combat.

Chopper as Gnar straght forward reason small Chopper fight with his brain then he turns large for powerful blows.

Robin as Zyra or Amumu for Zyra instead of plants she uses her hands the plants can just be larger hands slapping for close range and throwing rocks for long range only thing I dont like is her Passive, Amumu at first may seem werid but Q can be a wave of arms that grab you and pulls her to the target the E the hands spin around her body the Ult obvously Hands come out in a circle around her.

Franky as Blitz and I can see Draven cause his personality obviously Blitz cause hes a cyborg and his hand extends but Draven can work as well but Blitz is clearly a way better fit.

Brook as Yi, most keep saying Karthus but Brook is a swordsman who speedblitz people I figure he can use his soul to heal with music or something along that line the reat of the skills maych perfectly.
