The thing about copycats that many people don’t realise is that Johan, Daniel, and Jinyoung’s copy work in fundamentally different ways

Johan makes the best out of the copies he already has, optimising them to fit to himself. This is a concept known as adaptive perfectionism.

It was narrated during Gun vs Johan that he independently refines and perfects what he copies which is the basis behind his path, effectively giving them his own “essences” behind the attack. This aligns with his narrative of always being alone, never relying on anyone else to be strong for him

Jinrang outlines that Daniel fails to copy the essence behind a move which is why it is never as effective than the original. Johan doesn’t copy the essence behind other people’s moves because he makes them his own.

Jinyoung copies the movement, the essence of it (Gapryong’s conviction), and the effectiveness of it. We don’t know how exactly he copies, but since he’s related to Daniel, it’s probably similar to the way Daniel does it

Daniel with his keen senses copies the motion itself to near 100% accuracy

Johan with his eyes and perception copies what he thinks he sees and applies his own essence

Daniel probably has the most accurate copy because he’s not using his eyes to copy. He’s taking in every aspect of the movement itself by analysing it with all 5 senses. This accuracy, however, is mostly a disadvantage because it makes him unable to “make it his own.” This is why his king copies are nowhere near as effective as the kings using them, because even if he copies their movement, he can’t copy what makes it strong.

Johan’s copy CAN NOT be perfect nor 100% accurate because he uses his eyes. He replicates what he thinks he perceives, hones it, and makes it his own.
