Here is my two cents, I also think on affected areas when I try to measure characters
Human: Defined as a regular Human, just like US.
Low: Out of shape, or physically or mentally impaired
Middle: Normal People
High: Fit to Athlete level
Street level: defined as any human on costume with at least certain proficiency on a field be that fighting, camouflage, fire arms, armed combat very important, this is though TRAINING, NO META GENES, OR MUTANT GENES on action
low: Robin
middle: Nightwing
high: Batman
Meta human/mutant: any human with at least an extra gene that gives him an ability, be that bending spoons, shape shifting or an extraordinary ability, but this is due to some genetically difference from a human, it does not necessarily means that a low meta can defeat a high street level. The Level of area affected by power display also will raise the character on the tier.
Low: at least 1 ability capable to destroy/affect/cover a small area from a house to a building
Mid: at least 1 ability capable to destroy/affect/cover mid range area from building to several blocks
High: at least 1 ability capable to destroy/affect/cover a large area from several blocks to a city
Super Human/Herald. Majority of the genes differ from humans, be that due to gaining powers though freak accident or embed with them. The Level of area affected by power display also will raise the character on the tier.
Low: at least 1 ability capable to destroy/affect/cover a small area from a city to a country
Mid : at least 1 ability capable to destroy/affect/cover a mid range area from a country to a continent
High :at least 1 ability capable to destroy/affect/cover a large area from a continent to a planet
Super human/Herald Team Wrecker: an individual capable of fighting a team or a group of meta humans or super humans
Low : capable of fight a team composed of meta humans
Mid: capable of fight a team composed of meta humans and heralds
High :capable of fight a team composed of heralds/super humans
Trans the highest tier onto characters who still abide to SOME rules of logic.
Low: at least 1 ability capable to destroy/affect/cover more than one planet to 4 planets
Mid: at least 1 ability capable to destroy/affect/cover more than 4 planets
High: at least 1 ability capable to destroy/affect/cover a solar system
