User blog:First comes rock/Do you think Netero's Nen ability has any Vow & Limitation?

My theory about Chairman Netero's Nen ability:

Netoro's Hyakushiki Kannon is perhaps the strongest Nen ability we have seen so far in the series. But considering it being so damn strong (especially Zero Hand) does it have any possible Limitation to it? Also, on Zeno's saying:

"Hyakushiki Kannon, that's probably his most dangerous move."



That's like implying that he has various moves, with Hyakushiki Kannon being the most dangerous.

And what tickles my mind more is during the Palace invasion where Netero had a free fall, Pitou attempted to attack Netero, but all he got was the Chairman's aura blast pushing him away. While doing that, Netero said "I've anticipated taking a few different kinds of attacks." When I saw that panel, I thought that that aura blast might be one of his moves too.

If Netero really had various moves like I thought, then how can his Hyakushiki Kannon be that powerful? Maybe he placed a Limitation on it. And the Limitation might be: "This move will only be accessable when a '''worthy opponent is met." '''And who are these worthy? I'm guessing it's Meruem, Maha, and Zeno (since he witnessed it being used).

What do you think?
