Pocoloco's luck is added into his abilities.

Unstoppable force vs immovable object

I still think Hey Ya! has an advantage since it might also see the future, so if Pocoloco's luck and WoU's calamity is negated, it can still see the future.

WOU is stated to be>abilities that can effect time itself

It's force is simply stronger

Hey Ya! cannot perceive futures that contain unnatural variables he is unaware of as seen with Gyro and Johnny's use of the steel balls to cross the gap. That is if Hey Ya! actually does anything in the first place...

I love online debates

Wonder of U and Tooru just ignore abilities and just jump him.

Why the hell is everything in here about vsBattles💀

It's literally stated in jojoveller that Hey ya! has no powers
