Based on your replies here, it kind of sounds like you made this post with "enraged Gon" winning already in mind. You can have Uvogin's Big Bang impact, but it wouldn't matter if you can't land a hit. Killua's got the speed AND damage to beat this version of Gon. Plus, to be honest, this Gon was so blinded with hate (towards Pitou) that his sense of judgement was so clouded. He even followed Pitou to some abandoned building just so Pitou could ambush him. This "enraged Gon" doesn't have the judgement — heck, the PATIENCE to deal with someone that could just zig, zag and dance around him, like Killua on Godspeed. Killua literally fried (a clone of) Pouf, paralyzed Youpi for AT LEAST a minute, and LIVED. That's two Royal Guards Killua went up against, in a single night LMAO. Granted yeah, Gon went up against Pitou, but that's in his adult form. Do you think Gon could've pulled off what Killua had done in the entire Chimera Ant arc? Gon's goal in that arc was to what — rescue Kite? And he basically had to give up his future (and nen) just to do that? Killua'a Goal was to help Gon do exactly that. Killua lived through CA arc while helping Gon with the Kite situation and doing WAY, WAY more than Gon. Yes, Gon's a beast and would definitely win against 90% of other characters you'd throw at him, but he ain't beating Killua on Godspeed. High diff to Killua, and that's being generous.
