Speed

Speed
Speed is simply how fast a character can move in a given amount of time. There are five types of speed used for VS purposes: Attack Speed, Combat Speed, Reaction Speed, Travel Speed, and Flight Speed. The term "Speed" normally refers to Combat Speed.

Attack Speed
The speed at which an attack moves. For example, X character is hypersonic, but he can do an attack that is a natural beam of light, the speed for the attack is different from the speed of the user, hence the attack would be lightspeed even if its user isn't.

Combat Speed
The speed at which a character can fight.

Reaction Speed
Reaction speed is the speed at which a character can react to an event or action. This usually only grants a short movement upon reaction, whereas several movements at the same speed switch it to combat speed.

For example, let's say that character A shoots at character B with a gun and character B dodges. That is reaction speed. Keep in mind, sometimes a person aim dodges and it is not as good of a feat.

As another example, let's say that character A uses a minigun on character B, but the minigun takes a second or two to charge up and Character B sees this. If Character B dodges it is considered aim dodging since he/she knew that the attack was going to happen.

Reaction speed is reacting to an attack that you don't know is going to happen, or at a very close range. The reaction speed of a character also tends to be higher than its movement speed.

Travel Speed
The speed at which a character or object can move by running, or through similar means that do not involve flight or teleportation.

Flight Speed
The speed at which a character or object flies a certain distance, like going from the earth to the sun for example.

High flight speed logically requires similar reaction speed in order to manoeuvre when approaching different objects.

However, certain franchises, such as Marvel Comics (and DC Comics or Image Comics, which follow the same conventions), make a great distinction between regular movement speed and flight speed.

As such, we have generally assumed that the characters' regular reaction or combat speeds are roughly equivalent to their flight speeds unless this is clearly contradicted.

Conversion
You can use this calculator to convert from one speed unit to another.

Speed Levels
Infinite Speed (Able to travel anywhere instantly, or move an infinite distance within a finite amount of time. Teleportation does not count. For further information, see notes 4, 5 and 7 below.)

Immeasurable (Movement beyond linear time. This is why the speed cannot be measured. Given that S = D/T, if T is undefined the speed formula cannot be applied. This is the same reason why multiple temporal dimensions also grant immeasurable speed. For further information, see note 6 and 7 below.) Essentially feats this would account for is, existence in a place atemporal & Complete Trancendence Over Time

Irrelevant (Characters beyond, and qualitatively superior to, the concepts of dimensions of time and space themselves. Meaning: Tier 1-A and above.)

Other
Omnipresent (This is technically a state of being, rather than a speed, but has consequences for combat similar to that of a speed statistic. For practical comparisons, each case requires more detailed consideration.)
