So, I wasn’t 100% sure if this was a “Studio” question or a “canon” question, hence why Gon answers with two different possibilities here. I went with Huey as the Studio answer here because, as I thought about it, I figured that Gon and Killua and the Freeman’s probably bonded well during the making of “The Lovers and the Brothers“. That crossover came about largely by accident, and I know a lot of people were confused by it, but after working on that comic so long, The Boondocks and Hunter x Hunter are kinda inseparably tied in my mind now. Granted, DBZ and MHA are also tied to HxH in my mind for similar reasons, and this answer could’ve just as easily been with Goten or Deku or someone, but I find the idea of Gon and Huey connecting despite their disparate personalities too cute to ignore. It’s very easy for me to picture Gon’s relentless optimism and friendliness wearing down Huey’s more stoic, dour self in an “opposites attract” type way.
