In the various English versions of Hunter x Hunter, Kurapika shows his initial disrespect for Leorio in various ways:
1) 2011 sub: calls him "Leorio" instead of "Leorio-san"
2) 2011 dub: calls him "Leorio" instead of "Mister Leorio"
3) 1999 sub: calls him "Leorio" instead of "Mr. Leorio"
4) 1999 dub: calls him something like "Rewolio" instead of "Leorio" ( https://youtu.be/LaQEBndn-JQ?t=795 )
This discussion takes place in episode 1 of 2011 and episode 3 of 1999.
I'm pretty sure the disrespect is due to the way Leorio had been being rude to the Captain and Gon. Anyway, I'm most curious about #4. What exact name is Kurapika using? It is hard to tell with no text. Does the actual word mean anything in either English or Japanese?
