I always thought I liked Killua more. But after the Chimera arc, I think I gotta go with Gon. He showed a whole new side that I've never seen before and I'm pretty that won't be the last time we see it. Like this dude would've killed an innocent blind girl if he didn't get his way. Togashi broke Shonen rules with this one lol. In my opinion Gon is the best MC in all of Shonen. And even though I love Killua a lot, I just can't help being in love with Gon's character arc and how villain like he became....whilst Meureum became more human. Anyways I vote Gon.
