- Godspeed (Kanmaru): With his hair, hands and feet changed into electric type aura, Killua's Kanmuru ability allows him to react and move his body at speeds that would normally be impossible (even in Hunter × Hunter universe). This ability changes Killua's aura into a field capable of transmitting all electrical impulses from his brain in a straight line directly to the part of the body he wants to use, completely bypassing his nervous system. It is made up of two parts: Speed of Lightning, the ability to move his body according to his own will, used to travel long distances at high speed, and Whirlwind, the ability to sense his opponents movements and have his body react automatically, which he uses to evade enemy attacks with flawless speed and timing. Kanmuru can only be used for a short amount of time before needing to be recharged.
Does it make sense to you now? This ability transmits electrical impulses directly to the parts of the body he wants to control. With what I said before,
that's why he bypasses sharingan's precog. Can you read it now? Am I the one who doesn't know what they're talking about? I don't think so.
We
do know where the battle is taking place. Am I the one who doesn't know what they're talking about
when you're debating without having read the Standard Battle Assumptions? I don't think so. It's the Central Park, a wide area which takes 8-A to Low 7-C AP to fully destroy, with trees, fields, etc (I've never been there, so I'm speaking from Google Images). There is a lot of room for being stealthy there. I promise you I know at least better than you what is being talked about here.
Sasuke has chakra control?
And so what? You gave absolutely zero evidence that he can copy a technique with the
properties of Kanmaru. Why? Because you have no evidence it is
possible to create such a technique that electrically controls one's body with chakra and even less that it can be copied. You're just extrapolating things from Sasuke being able to copy "a lot of stuff and learn a lot of stuff" in Naruto to him being able to copy
any skill you want him to, which is why I call it No Limits Fallacy. Don't make me have to ask if you know what
that means.
Killua
would be able to use his stealth because it is
possible to use his stealth in this place — am I really the one who doesn't know what they're talking about? — If he can, he will, and that gives him the first attack. Sasuke's precog doesn't do shit if he cannot see his opponent coming, so he
dies there.
Am I the one who doesn't know what they're talking about? If the battle does proceed, Killua has several small advantages that stack up on top of each other to allow him to win, in case you haven't noticed.
Sasuke may have stronger long range attack, but he cannot use them if Killua is not in range, and Killua's range is larger. meaning
his attacks are of little use despite their strength. Had you forgotten that, or were you ignorant of it?
Sasuke will
not see through Killua's Rhythm Echo, and that's because Killua has already fought people who were proficient at seeing aura (he had trained to use Gyo at pretty much all times and his opponents were at such a similar level) and yet they failed to guess the real Killua out of the clones. Overall, the Rhythm echo is a technique that can fool pretty much anyone who faces it, and the series is definitely not lacking in characters capable of no-selling abilities to hide stuff, confuse or outsmart people. Did you not know what you were talking about?
Am I the one who doesn't know what they're talking about? Really?
