Questions & Mysteries Netero basically breaks the rules of nen

[Bob74h]

So it's established that to acquire grand nen powers, you have to put restrictions on yourself so kurapika would be as powerful as he would be as he gave up, his ability to harm other people just to amp his powers. Another example would be kaito like has to get random powers on draw just to use his powerful nen abilities yet netero despite all known statements and showcases has arguably one of the most powerful nen ability despite no restriction had

The guy is 110 Years Old, he dedicated most his Life to Prayer & Punching till his Punch became Faster than Sound

And Netero has to make a set of moves before activating his Nen powers.

If he was some random doing it will create lots of openings for the opponents but he can do it so fast because of training

And the moves before attacking ? It’s likely a restriction
Even Meruem made a comment about it. Saying it was crazy to make those moves but Netero was so good it didn’t change anything

The restriction could have been the amount of training he did + the constant prayer motions before every attack

 

[Chrono]

High potential combined with a life of pure training.

 

[Kiiro]

Well, it didn't make him stronger than Mereum
