Question over attack speed

[Professor_Voodoo]

I plan on creating a Samurai Shodown(fighting game franchise) page in the future.

My question is.....a lot of the characters have physical attacks that have either afterimages, trails, or they catch on fire/are enveloped in light when the attack is initialized.

Where would each of these specifics fall under?

Afterimages

Attack trails

Catching fire/light envelopment

You need to be moving faster than the human eye can track, which can vary on distance, but is somewhere in the single-digit Mach range.

No idea.

Catching fire requires you to be Mach 5.

According to what I know so far, afterimages at least require a 'faster than the eye can see' speed. If it's lower or higher than the speed of sound, it likely depends on few other things.

I dunno about attack trails, it's possibly like catching on fire, which requires a hypersonic velocity, meaning Mach 5 (5 times the speed of sound) or above.

Good luck on creating the new page !
