Speed Tiering

This is a order of different speeds characters can attain. (Note: the Negative (-) sign means that a character is at the low end of a tier & the Positive (+) sign means that the character is at the high end.)

Tiers
F Class: This is the very low end speeds of weaker characters such as humans (However, there are some beings who have this class of combat speed and are well enough above humans). Peak Humans and slightly above are the high ends of this tier and some might even able to reach at least Subsonic speeds (Up to Mach 0.8).

D Class: Characters in this tier can reach the speed of sound. High ends can reach Supersonic speeds (Mach 1-5).

C Class: In this tier, characters at the low end can reach Hypersonic speeds (Mach 5-10) while those at the high end are able to move at High-hypersonic speeds (At least up to Mach 19).

B Class: In this tier, characters at the low end can reach Re-entry speeds (At least Mach 25) while thse at the high end are in triple digit Mach speeds.

A Class: In this tier, characters at the low end can reach even higher into the 1000+ Mach speeds. Those whom are at the high end are capable of moving at Mach 10,000+ and can be catalogued as "Sub-Relativistic".

S Class: In this tier, characters at the low end are able to move at Relativistic/Sublight speed. They are capable of moving at 10% lightspeed up to (but not including) lightspeed. Those at the high end are actually able to move at light speed.

Z Class: In this tier, characters at the low end are at able to achieve light speed to 100x the speed of light, while those whom are at the high end are capable of moving at speeds that are massively faster than light.

Infinity Class: In this final tier, characters at the low end are capable of being nearly omnipresent/Infinite in speed, while those whom are at the high end are actual omnipresents/Infinites in speed.
