Is the Chimera Ant Arc the greatest single arc in any manga ever released? The multi-faceted villain, whom we see grow from remorseless monster to the most human character on the cast juxtaposed against the main characters depraved, selfish fall into the role of a monster, is probably - no - undeniably, the single greatest act of story telling in the medium.
The fights are amazing. No ''I fly and shoot laser bams'' bullshit here. They are fights between actual complex characters who have their own motivation. And Nen is such an interesting power system that it never devolves into a numbers game like the usual trash that populates the genre. With one exception - the King. He's superman who fully recognizes he stands the top.
So we both get to see Nen fights between varied people with amazing powers, strategizing because the power gap is so large, we also get to see some poor, pitiful old man, who just can't get the picture he's outclassed. That he may be a hammer, but the nail is bigger than he is. But he keeps hammering away. And then he dies. Having done no damage. His whole life dedicated to achieve power, wasted. By someone simply born better.
And Gon! He's gone! The MC left the story entirely. The sheer balls of Togashi to do this!
