How Knov appearance kept on changing?


In _Hunter x Hunter_ , at first Knov's appearance was pretty bold and looked
smart. But after knowing the fact that their enemies are stronger then he got
scared.

First change: His hair got white and he was a little bit skinny.

Second change: Hair loss and lack of physical fitness.

But being a Hunter, why he undergoes such a huge change in appearance? I mean
how come his whole physical body changed? They knew that the mission they are
going into is really scary, but what was the reason behind his complete
change?




His appearance changed because he was so terrified. The idea was that he was
so scared of the beings they were exposed to that his hair went white and he
rapidly lost weight.

Stress can cause rapid weight and hair loss. I don't know if hair turning
white from fear is real but it is a common belief (see crash test dummy's
MMM). That is what you are seeing exaggerated here. What you are supposed to
note as remarkable is how he continues to aid the group and stick with it even
though he is so debilitated. He is more scared but somehow the bravest GD
person there.
