Gon has a lot of experience fighting villains. Especially villains with powers that are potentially dangerous. Tower can turn big, but that won’t help him in the least. For all we know it might just end up hurting him. Gon wins.
Vindaloo is another guy with powers. He has flammable goo. Of course that won’t do much against Gon the mighty. Gon is now nearing 90 wins. He will have been the first to do so. Gon wins.
Mephiles has dark powers and was able to fight Shadow. Gon is one of the stronger Shounen Jump main characters, but Mephiles is possibly the strongest Sonic character. Mephiles also has a super form. Mephiles wins.
Shio and Gon are almost exactly the same. They have mostly the same powers and there super forms are very similar. I’d say Gon is slightly faster and stronger. Which gives him the obvious edge. Gon wins.
Gon has super speed and super strength. Static has a gun. That isn’t bad, but well guns don’t help much against Gon. Gon’s aura can stop it. Static goes to the lonely 0-1 section. Gon wins.
Static has some mild powers but not nearly enough to fight Gon. Gon’s strength and speed outmatch Static’s powers. Static is another villain to fall to 0-1. Gon keeps rising to glory. Gon wins.
Gon has super strength and speed and more (See any of his other fights) Spoor is okay but let’s face it. He couldn’t beat Gon at a 1/20th of his power. That means Spoor joins the 0-1 group. Gon wins.
Rem Ram is okay, but can’t use his dream powers to their full extent when the person’s awake. Gon will be awake in this match so Rem Ram can forget about winning. Now Gon has over 80 wins. Gon wins.
Projector can make barriers. Which is all well and good, except that Gon would probably be able to shatter them pretty easily. Gon would be even stronger if his series was not on hiatus. Gon wins.
Orator is a very unpopular character. He has empathic powers, but beyond that there isn’t much known about him. Gon has super speed and strength that could take most people out. Gon wins.
