I feel the same, man. I really would like it if they made alternate versions of other characters besides just Luffy, but that's just me. Still, the game is looking awesome despite that, plus I'm VERY eager to see Kung Fu Luffy in action. :)
yea Luffy seems to be getting the Special Treatment
like they could have done a few cool Alternate/What If DF Powers Characters like these only as examples
! >! Nami with Eneru's Devil Fruit Power
Robin as a Dual Fruit user of her Hana Hana Fruit & Ace's Mera Mera Fruit
Boa Hancock as a Dual Fruit User of her Mero Mero Fruit & WhiteBeard's Gura Gura Fruit
! Kung Fu Sanji
Armored Knight Franky
Chopperman
