Suggested by iKnowledge Leorio has his nen abilities now so he can put a much better fight than back in the day but he still hasn’t shown enough to be able to stop Rock yet. Rock has aura abilities of his own and much better close quarter combat skills so it’s hard to see him going down. He’ll be able to react to Leorio’s attacks well enough and counter appropriately. Leorio won’t be able to keep up. Rock Howard wins.
Killua has some pretty impressive speed on his side. Leorio may have gone up against Hisoka in the past, but he definitely doesn’t stand a chance against Killua. One good blast of electricity and Leorio should be down for the count. Killua definitely had a field day with wins today. Killua wins.
