So we've seen that post-mortem nen can be coded (and we've seen some fairly clever programming in nen abilities, such as Bomber). For the right price, nen can now do almost anything plausible in the universe. So there are two questions left: 1) Is it possible to resurrect in the world of HxH? 2) What would be the cost? Just to emphasize that this isn't obvious from our previous discussion; whether Hisoka actually died in the sense that his brain stopped functioning completely is arguably ambiguous; one can go a fair amount of time with their heart stopped before they die, and in the HxH world, we can assume everyone is a little superhuman.
While Chrollo did beat Hisoka, it should be noted that he had put in a huge lot of preparation to pull this off, as he admitted to himself. He had previously planned a strategy and acquired Nen skills to assure his triumph before the encounter. The fight took occur at the time and location specified by Chrollo. As a result, he was able to effortlessly manage the crowd and employ them in the battle. After resurrecting, Hisoka stated that he would fight Chrollo in a location of his choosing the next time.
5. Is Hisoka Less Capable Than Chrollo?
Although Chrollo eventually defeated Hisoka, it is vital to remember that he had done a lot of preparation before to this encounter. Even he conceded as much. Before the duel, he devised a plan and acquired Nen talents to assure his win.
Milluki appreciated having the freedom to be a bit rebellious as the second Zoldyck kid. It is common for parents to put all they have in their first child: money, dreams, attention, and aspirations. It is not necessarily a positive thing. Milluki was not subjected to this. Silva and Kikyou are less stressed about having a perfect kid. They have Illumi for that.
