The Superhero Database Classification number, or SHDB Class, is a number that represents the overall 'power' of a character. All traits of a character are used for calculating the Classification.
What it DOESN'T mean
This doesn't mean that a higher class would always beat a lower class character. But the bigger the difference in Class is, the more obvious it is who'll win in a fight.
How is this calculated
( INT^1.3 + (STR*0.5 )^2 + (SPE*0.5)^2 + DUR^1.6 + (POW + (SPS*SPL))^2 + COM^1.8 ) ^ TIER
Super Power Score and Level
Every Super Power has a score (SPS) that is used to calculate the Class. Each Super Power also has 3 levels (SPL). The level is set when connecting that Super Power to a character. The level determines the final score, of the Super Power, being used in the calculation.
I Vote for Captain America because He is Legendary Marvel Superheroes as well!
In Addition as He also Beat Colonel Miles Quaritch at Very Easily with Shield, Especially when They also Take Place in Earth. But However When If Battle that Take Place in Pandora, 2154 that mean Captain America will be Forced to Wear Exopack due to Pandora's Toxic Atmosphere that which Makes it Extremely Poisonous to Humans, Rendering Them Unconscious in about 20 Seconds and Causing Death in about 4 Minutes when They Venture Out Unprotected by Specialized Breathing Masks. as Quaritch also able to Survive Himself by Wearing Exopack that Enabled Him to Survive Pandora's Toxic Atmosphere, But Despite These Extreme Hazards of Pandora's Atmosphere. Captain America (while Wearing Exopack If Pandora was Chosen) will Still Win the Fight against Quaritch as well, even with Facing These Pandora's Toxic Atmosphere that which is Unbreathable by Humans due to the Presence of High Concentrations of Carbon Dioxide (>18%) and Hydrogen Sulfide (<1%).
