Shout out to Konan, greatest kunoichi in Naruto, who actually kills Obito with her Paper Person of God Technique-- which required 600 billion paper bombs, effectively deforesting the entire ninja world and leading to the ecological collapse we see in Boruto.
Too bad these Uchiha got h4x for no raisin. I feel like that's applicable to every part of Naruto at this point.
Exceed Obito's natural power usage of 5 minutes to counter Kamui, literally the most absurd mangekyo ability, fuck it-- Izanagi, don't even need a goddamn Mangekyo. Obito's probably got a dozen of the things in storage.
