Suggested by Destroyer Kazuki is a pretty talented kid, but I don’t think he really has much of a chance against Obito. Perhaps if he was fighting Obito without any powers, but once the Uchiha got his Tailed Beast form it was all over. Even Kazuki’s pseudo Super Saiyan technique wouldn’t be enough to turn the tables from that. Kazuki is simply outmatched here but I do think the fight would probably be a fun one to watch. Kazuki has enough durability to drag the match out a bit before he goes down. Obito wins.
