That doesn't work such way.
As I said character claims mean little if it contradicts with the feats. I can say that I run at FTL speeds, no one would believe me. Same way, there's no proof of Kizaru moving at speed even approaching the light. He's very fast indeed but we have a number of counterproof to make his statement of lightspeed false. You are gasping to the straws here
Sure it does in One Piece, you are once again comparing your real life scenario with that of fiction, of course no one would believe you, you are a normal human with no powers or anything, however if you absolutly controled light and all it's properties and then proceeded to run so fast no one could even see you even without blinking then sure, that is what Kizaru did, he kicked Hawkins throughthe building, his men who were watching did not even notice until a few moments after. No one is grasping at straws it is simple knowledge, he controls the element, it's like trying to say Madara Uchiha can't absorb giants because he never has done it, despite being able to warp anything. You are the one grasping at a counter claim here.
Also speaking about lightspeed both Crimson King and Ban has so-called "lightspeed feats" where characters claimed to move at the speed of light. In SDK we have Hishigi's slash that even the narrator says to be lightspeed. Yet even mid-high tiers like the Yuan dodged that while being exhausted. FCK is top tier in terms of speed and everything at the SDK-verse. Is he casually FTL then even in base? That makes him 10 times faster than that with Sekireigan. With such speed he can effortlessly blitz Kizaru even as a mass of light or see lasers in slow motion. We can even go on this route.
I said before that they could take out Kizaru, but the thing is while Kizaru can also travel light speeds he has shown to be able to teleport shown when he first arrived and teleported onto a canon ball, I beleive teleporting is faster than any kind of movement. Not to mention Kizaru's attacks (Raining light, firing lasers, flight ect) how will he see or hit light anyway? At any rate I need not make an argument for Kizaru wining a battle seeing as how it is 6 against 2, the other 4 can win this as it is, since we already decidedBan would go after Kizaru and FCK will go after Akainu, I still don't see why a simple gear third axe wont take them out regardless of how fast, how will they dodge if they have no place to go? Not to mention the freeze and die when touching aokiji or he can freeze the floor.
Whichever, he so much over in terms of speed that it doesn't matter what the opposition can do. They are getting hit with pseudo blackholes, taken their shadows and frozzen to absolute zero before they even think. What more they get harassed with whole armies of FTL instantly reforming Mibu Blood Soldiers. Sounds ridiculous already, isn't it?:p
Not at all, you are trying to make them sound really powerful when they aren't, every speed feet for Getbackers has been done on one guy, not 6, you have opponent in the air, long rang and such, Luffy and Zoro have been shown to hit shadows such as with moria, Blackholes? The one that only sucked one guy in? From that scan that is no more powerful than the black hole Blackbeard used. Aslo I never saw these attacks activate at FTL speeds, mind showing me? So far only one person has attacked at light speed, every other person has only had claims of dodging fast. Attacked by reforming soldiers? Again Luffy and crew, while weakened fought soldiers (Reforming shadow bats, soldeirs, zombies. Mainford Soldiers, some that were CP9 level ect) not to mention Aokiji can easily freez them all the moment the attack him or freez the field. Sounds riduculous already doesn't it?
I generously and out of reason dissuaded the whole FTL legend on SDK. I made the compromise to keep the discussion on more sane levels. Yet you still come with Kizaru's lightspeed hyperbole...
Yes, hyperbole since it contradicts with about every single feat of his. Is he holding back majorly then?(like about showing 0.0001% of his true strength)
Maybe yes but Occam's Razor always point to the simpler solution which is more grounded in reason. Kizaru can't move that fast. He was simply lying. No one in One Piece, including him had ever explicitly shown speeds ever approaching lightspeed. Point.
So basicly your argument is Ichiro Oda is lying to us, the author, because it does not fit your real world logic, or that of other anime with different aspects to what FTL is? Great, moving on
Back to topic, Chinmei had shown to repeatedly react to cloud-to-earth lightning. In short he reacted to real lightning, not some made-up magic electricity like most electric attacks. He even moved away in time when Sasuke already released it at him. The lightning true to its name is extremely fast. 150 kilometers per second at the very least. It can even go up to approach relativistic levels. Dodging lightnings after they were released is considered to be just a step under reacting to lasers. And Chinmei is still slower than the FCK. To translate to Mach values the lightning moves with at least Mach 437 but usually well into the thousands of Machs. Hypersonic speed is Mach 5. The speed of sound is obviously Mach 1. One piece characters are at best into the double digits in speed. And again it's Chinmei. FCK is faster AND has the Sekireigan to manipulate time thus move 10 times faster than normal.
That's great, but Aokiji jumped above the clouds in a second, not including running speed, maybe not faster than lightning however it is fast enough, not sure what your point in this part of the argument was.
And it doesn't matter if the opposition is 5 people or 10. Being massively( roughly x10-100) faster means the Crimson King can pass 100 meters while the rest just one. He can do hundred actions while the OP characters can only one each. And it isn't a turn-based game. It means the FCK had already moved before the rest just thought about fighting. Plus even if they do react their attacks have velocity and speed. Even blasts take time to reach a certain point. With his superior speed he can literally outrun those with complete ease. That's a true and utter speedblitz where the opposition just stands like sitting ducks and hopelessly watching as they die.Even if he has inferior power(which he isn't really), he can just repeatedly hit the same spot until it breaks. Durability means little here. Plus FCK has the hax to take them down without caring about how tough they are. That's the Former Crimson King, one of the most badass fighters ever made in fiction.
Has he fought this fast against multiple people? If so show me him casting these spells and such at FTL speeds, Aokiji would kill him the moment he touched him, Luffy crushes him ect. No saying he wont kill any of em, but every moves he has done, he stops and uses it one one person, I have never seen him attack multiple, if so please show me.
