Luffy’s 2 main gear 4th forms are boundman and snakeman with one focusing on attack power and the other attack speed.
What if he actually has something similar for defense as well?
We already know tankman exist even tho we only saw it once and the stuffed version at that. With tankman basically being the defensive version of boundman it man focus being to straight up tank attacks
Imo that might open up the gate a bit for a defensive version of snakeman. A form that focuses on dodging and avoiding attacks instead. A form that like snakeman relies heavy on observation haki. It basically working like kami-e/paper arts
