The ultimate antagonist in Naruto is Madara Uchiha. Among the high level slayer creatures, abyssal demons are up there with the requirement of 85 slayer. Why would they take the same skill level to kill? Because they use the same tactics in battle! For the longest time, Madara was believed to be dead. Now that he is back at the forefront of peoples minds, though, more and more is revealed about his abilities. His most powerful ability, though, is the ability to bend time and space to be able to teleport at will. He uses this ability to dodge almost all attacks and counterattack in ways that most opponents cannot even harm him. He can also use this ability to teleport other people into his own realm, adding to the difficulty of fighting him. Abyssal demons have the ability to teleport as well. They can also teleport you around as you are fighting them, adding to the confusion. Both of these abilities in unison make it so that most players cannot deal damage to them. It takes the skill and speed of someone with 85 slayer to even start to damage an abyssal demon. Once you obtain that level of knowledge, you learn techniques that allow you to time your hits with the demon's teleportation, allowing you to kill them. With that theory about why 85 slayer is required to kill abyssal demons in mind, one could link that ability to time your hits with teleportation to Madara's ability to teleport. So, the end result is that Madara requires 85 slayer to kill. Just don't forget, this just allows you to get past his teleport ability, you still have to deal with one hell of a fighter in combat. So the question here is, what would his other abilities mount to in rs terms? With our skills and combat abilities, do you think we would be able to take on Madara? What about other antagonists and protagonists from books, movies, or shows? Note: I was not sure if this belonged in general or off topic, so I put it here. Please move it if this is the wrong spot.
