So i asked myself today, can a person eat more than 1 smile without dying like it'd happen with a regular df? or can a devil fruit user eat a smile without dying? if so imagine the posibilities from kaido's army
That most probably cant be, and if that is by any chance the truth, I am sure Doffy and Ceasar would have know it by now, I mean, Doffy wouldnt be that crazy as to give Kaido that many smiles since it would make him literally invincible and unbeatable, which would make Doffys ambition of becoming the Pirate King more hard to achieve. On the other hand, if a special smile with those characteristics would ever be revealed, I am sure Vegapunk would have something to do with its production.
