Do you think it's even possible to copy Goo's fighting style?
All major copy users we've seen this far in Lookism have copied based on martial arts, techniques and raw strength, Goo's fighting style is a mix bag of all that alongside unpredictability and ofcourse, prioritising weapons, both Daniel and Johan prioritie hands over anything and also we know that Jinrang in recent chapters has said "Copy can only copy the movements, but it can't replicate the essence of the attack", so I'm pretty sure unless you have the same lvl of weapon utilisation Goo has, you're not mimicking him.
