Completely false. Do you have any idea how fast mach speed is?
- Deva not only stabbed two clones but leisurely dodged at the same time. Deva path has never been portrayed as having an extremely high speed. Even then, if you didn't notice, he was literally stationary when he stabbed the clones. They hit the ground and disappeared. After that he jumped a little into the air - it was such a small leap - and FRS was shown to cut through all the debris. It bamboozles me how you even imagined that FRS has such a high speed. Heck, Kakashi, Chouji, and his father had no trouble keeping up with Deva. He only bested them with Shinra Tensai, which obviously has little or nothing to do with Bodily Speed.
- Third Raikage only has V1 . He was shown to dodge FRS effortlessly, twice. He lacks V2 and you know how he compares to V1 Ae? He's considerably slow and even that would be an understatement. Juugo never kept up with Ae, who blitzed him twice in such a painful manner. He was mostly keeping up with Bee just fine. In fact, Lava Balloon and Doton Walls were used to counter all moves from Third with ease. Lava Balloon was used to save Naruto when Third was literally just a few feet away. All relevant ninjas anticipated and built defenses for his speed and hell stab. Where does that put FRS?
There is not way in hell FRS is that quick. Not even close. This thread has blown things out of proportion.
