Comparing Protagonist-class Beings (and Defining Tiers of Reality?)

[SimonMoon6]

how about a different kind of logic for discussing this:
your level of power is inversely proportional to the amount of logic you are bound to. the more power, the less external logic your bound by. thats why someone who can use both ice and fire is better than someone who can just use fire for thematic fire reasons, because there is less logic limiting the former person and thus more versatility given to him, and thus the more logic you hold something to, the less powerful it gets.

I'm not sure about that.

Consider Green Fury, the character that was later turned into Green Flame who turned into Fire.

Green Fury (who was a businesswoman) had fire powers. She could breathe fire. That's it. Except... she could breathe out cold fire because that's a thing, right? And she could snort fire out her nose to allow her to fly. And she once breathed her fire at someone's head... but she didn't kill him or anything; she caused the fire to use up all the oxygen around his head so that he would pass out. And she also had hypnotic fire powers too because why not.

Fire aka Green Flame (who was never a businesswoman but was instead an ex-spy) had fire powers. She could breathe out 6 inches worth of fire and that was it. Then the gene-bomb (from Invasion!) happened and she gained different fire powers. She could basically turn into fire and fly around. Plus she could hurl flame (and more than six inches away). And since she was now made of fire, solid objects would pass through her. (But how can a person be made of flames? That doesn't make any sense or have any logic to it.)

I'm not sure that either of these are more logical and sensible than, say, Equinox the Thermodynamic Man (with fire and ice powers) or Celsius of the Doom Patrol (heat and cold powers). They really don't have special gimmicks other than fire and ice or heat and cold. (Well, Equinox has a few weird gimmicks but none of them make him powerful; his appearance is constantly changing and his icy areas are actually hot while his fiery areas are actually cold.)
