User blog comment:FairyTailFan7/Sting's Attacks Are Light Speed?/@comment-26715029-20150820131706

I've been talking to a guy who is very knowledgeable in Fairy Tail. In fact, I believe the work and research he put into this is accurate if I do say so myself.

None of this below is my work or words for that matter. This information is from this guy. [] How fast is Natsu Dragneel? Now I'm going to use Natsu as of the tower of heaven arc, I will use links, logic, feats, and calculations to prove my claim.

First off we need to know how tall the tower of heaven is, some great pictures I found help this out a lot

This is he tower before absorbing the etherion blast http://m.mangatown.com/manga/fairy_tail/v10/c077/13.html

And this is the tower after absorbing the etherion blast http://m.mangatown.com/manga/fairy_tail/v12/c094/11.html

In both pictures we can clearly see that the tower is around the same height as the clouds, now these are specifically cirus clouds which are between an altitude of 16,500 feet to 20,000 feet. Just to be safe I will be using the absolute minimum which is 16,500 feet high

http://m.mangatown.com/manga/fairy_tail/v12/c098/9.html http://m.mangatown.com/manga/fairy_tail/v12/c098/10.html Now these links show pages where Natsu has jumped the full height of the tower of heaven by pushing a single foot against air in roughly the duration of 1/500 of a second or less

Now this time frame is justified considering this

http://www.100fps.com/how_many_frames_can_humans_see.htm

It basically says that 1/500 of a second is enough to escape peak human level comprehension

Jellal is obviously far above peak human level and could easily comprehend much more, so let's place him at 1/1500 comprehension for now for the high ball part of the calc

Now here comes the math, in order to figure out what Mach that would equate to we have to see how far Natsu could travel in an entire second as opposed to 1/1500 of a second, so I multiply 16,500x500=8,250,000 feet per second.

8,250,000/116.43701=70,853.7603

For comparison Mach 1 is equal to 116.43701 feet per second which is commonly known as the speed of sound

Now granted Natsu did gain a boost from dragon force and we can't ignore that, in the oracion seis arc Natsu obtained dragon force again for his fight with zero

http://m.mangatown.com/manga/fairy_tail/v19/c160/3.html

As you can see here Natsu said his power tripled aka times 3, he also has considerably more scales in this version of dragon force so let's set his etherion dragon force at an X2 boost rather than X3.

Etherion dragon force http://vignette4.wikia.nocookie.net/fairytail/images/a/a8/Dragon_Force_Anime.jpg/revision/latest?cb=20100802140153

Flame of rebuke dragon force http://vignette4.wikia.nocookie.net/fairytail/images/2/23/Natsu_Dragon_Force.jpg/revision/latest?cb=20140630210432&path-prefix=it

So we divide 70,853.7603 by 2, and get a result of Mach 35,426.8802

Now for the high end

20,000x1,500=30,000,000

30,000,000/116.43701=257,650.038

257,650.038/2=128,825.019

Final result-Natsu as of the tower of heaven arc is 35,426.8802-128,825.019 times faster than the speed of sound which places Natsu at the top of the Mach tier aka reentry>high hypersonic>hypersonic>supersonic>transonic>subsonic. Reentry speeds start at Mach 25 which Natsu completely dwarfs.

Low balled Natsu is a little over 4% light speed which is sub reletavistic

High end Natsu is a little over 14% light speed which is reletavistic

Remember this is all as of the tower of heaven arc

All the arguments provided are wrong, not to mention common

Things like kid Goku did it but he's not light speed so Natsu isn't light speed, well that just doesn't make any sense. Like I already said there's a line between something that looks like a laser and is a laser

For example when gray saved juvia's Life against the mini dragon things in the dragon invasion, it looked like he pushed her out of the way of a laser, however there's not any proof that it's a laser except for it looks like one

Asking if there's proof of magic light being as fast as actual light, is probably the worst argument of all. As light the burden of proof would be on the person claiming it's not light speed...since it's already light it's safe to assume that it's light speed (duh lol)

Not to mention I have several other feats where he moves at such speeds

L-Light A-Amplification by S-Stimulated E-Emission of R-Radiation

-Mach 1=340.29 meters p/s -1mile p/s=1609.334 Meyers p/s -Light speed=shadow speed (since shadows are literally a lack of mass, the have no mass at all)=186,282 miles p/s -1609.334x186,282=299,789,956.188 or simply E -299,789,966.188/340.29=880,983.7379529225 -880,983.7379529225 rounded up is 880,984

That does include the sting's roar feat. But it also has rogue's roar and future rogue using several light and shadow Attacks...none of which hit Natsu in that panal
