Leorio isn't a fighter, to be honest I don't want to see him fight. I want to see him accomplish his dream, which has nothing to do with combat.
I agree with futurefrog mostly, its just going to be a long road, and I hope we actually get to see some of it. Like what school is he accepted to? What is being a doctor like in the Hunter x Hunter world? etc.
Though I would love to see his nen further developed badly. Maybe he can use his nen for being a Doctor? That'd be awesome to me. I mostly just want more development for his character even though I know he's a side character.
I think Leorio will only become a doctor after a time skip since it would take years of schooling.
Anywho Leorio's ability is perfect for him.
He can do surgery with his emission hands while doing a through examination on all the hot nurses with his own hands. At the same time.
Now that's multitasking!
I like to think that Leorio will play a major part in whatever the final arc may be. I imagine some moment in which he saves Gon or maybe Kurapika with his medical expertise he has learned. I would prefer Kurapika though.
There will have to be a time skip though for Leorio to be a doctor.
:p you trollin'? If we don't get more Leorio being awesome, I'll honestly rage. Note I thought Leorio driving the car down stairs in the 1999 anime "awesome" or Leorio tricking the Spiders into thinking he's yelling over the phone awesome.
Leorio should be in the next arc, would be a shame for him to go off to "study"(Like he really is doing any of that) once again. Sure he can become a doctor in the end, it doesn't mean he can't go off adventuring every now and again. It also seems that he regrets not helping Gon, so there is a perfect excuse for him to join up again.
Gon and Leorio! journey to the Dark Continent... make it happen Togashi. :3c
Leorio for Chairman! Oh wait...
