Who is faster, Flashy Flash or Speed-o'-Sound Sonic?


At some point in the webcomic, the speed of Flashy Flash's attack is given: it
takes a centisecond to perform each attack. I suppose his speed can be
calculated if you know the distance of his attacks. I don't know if
Speed-o'-Sound Sonic's speed is given or it can be calculated, though it
probably has to be over the speed of sound, right?

Who is faster, Flashy Flash or Speed of Speed-o'-Sound Sonic?




From [here](https://onepunchman.fandom.com/wiki/Speed-o%27-Sound_Sonic), which
is also from the _One-Punch Man Encyclopedia_ , it says that Speed-o'-Sound
Sonic can enter _massively hypersonic speeds_. [Hypersonic
speed](https://en.wikipedia.org/wiki/Hypersonic_speed) has a minimum of Mach 5
(1,715m/s). Meanwhile, Flashy Flash can perform 1 attack per 0.01s.

Not sure about my math but if we assume that each attack's distance is a meter
long for Flashy Flash to achieve 0.01s, then Speed-o'-Sound Sonic can perform
an attack at that same distance for approximately 0.00058309037s, given his
speed is in Mach 5, which is the minimum for hypersonic speed.

This means that, based on approximation, **Speed-o'-Sound Sonic is much faster
than Flashy Flash since it takes him less time to perform an attack**.




While I do like Sonic much better, it's pretty obvious from what we've seen so
far: (Manga Spoiler Alert)

1.Flashy and Sonic were from the same ninja village, same ninja class (44th
"End Class" or whatever), same generation. Flashy was number 1 from this
class.

2.The two ninja dudes (upper classmen from the same ninja school and village),
that ate the monsterfication cells, were much faster than Sonic, while Flashy
beat them pretty easy 1vs2.

Although Sonic is currently slower, I think that he will catch up at some
point and maybe even surpass Flashy.
