User blog comment:Bennlimos/Netero (Prime) vs Adult Gon?/@comment-5780397-20150826091509

Oh, how I love this question. Hypothizing that Gon sees Netero as a threat (let's say he murdered Kite), he probably wouldn't get the same amount of power he got when fighting Neferpitou, because Neferpitou should be stronger; however, let's imagine he receives the same boost he obtained against Neferpitou.

Adult Gon vs Prime Netero

Prime Netero wins easily, perhaps even without using Hyakushiki Kannon. When spying the Chimeras with Knov and Morel, Netero claimed that his power had halved since his youth. While it is likely that this is an overstatement (which is pretty typical of him), this speaks for a great amount of power. I don't see how Gon could win: even if his Vow allowed him to get stronger over the course of the fight, I don't think he could get much faster or stronger than a battle genius Netero capable of moving faster than the speed of sound.

Adult Gon vs Old Netero

Even in this case, I'd go with Old Netero, simply because Gon would be unable to land a hit on him. Hyakushiki Kannon would massacre him before he could get close, though he might be physically stronger in close quarter combat. Isaac should have been easily crushed by Neferpitou, yet he sent the poor ant flying without effort. Indeed, Pitou took no damage, but Adult Gon does not seem to possess that degree of durability.
