Bro Joyboy most likely had a op power with VoAT too which Oda safe for the final war...
How broken was this guy, if VoAT is really a new powerful haki version which only Joyboy/Imu had, then you can imagine how OP they been.
I think Roger had VoAT too, where he was able to fight off Whitebeard Gura power.
But Joyboy VoAT most be a another lvl...
If VoAT is indeed a special unique ability as I think it is, then GG, Joyboy was really a monster.
I except VoAT ability to be broken
It gives psychic powers
This is how Luffy might end up reliving the past or see Joyboy in the real of the sports
VoAT mastered --> can speak to anyone or affect their mind
CoC mastered --> can nullify or at least supress dfs for a while
CoO mastered --> see the future
CoA mastered --> affect internally
Df mastered --> affect yourself or the environment
Joyboy mastered everything COO, CoA, VoAT. CoC amd Nika fruit
Luffy is yet to unlock the full potential of VoAT and to master CoC fully
If Roger had Nika fruit, he would have had support from sea kings and Emeth who were all waiting for Joyboy
I wonder who was the joyboy 200 years ago
