The variants of Charlie Kirk range heavily in overall power (strength, speed, wit, etc..) so Kirkipedia has chosen to create tiers of power the variants fall into. These tiers are not final and are subject to change.
These tiers include:
Tier 0 - Unknown Power/Inconsistance Power (i.e a variant that's durable but passive)
Tier 0.5 Animalistic (i.e a non-human variant that's most similar to the average animal)
Tier 1 - Average Human
Tier 1.5 - Advanced Animalistic (i.e a non-human variant that's stronger than the average person)
Tier 2 - Legendary Human (i.e a variant that's mixed with a powerful historical figure)
Tier 3 - Above Human (i.e a human variant that has been upgraded with technology or something else)
Tier 3.5 - Legendary Above Human (mix of tier 3 and tier 2)
Tier 4 - Superpowered
Tier 5 - Divine (i.e a variant above superpowered or a demi-godlike variant)
Tier 6 - Omnipotent
