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.
1 Mid-Tier / Low Herald
1 Mid-Tier
1 Street-Tier
Thanos might struggle with the speed of Flash, Superman, and Wonder Woman, but he resists their best hax (even the stuff Flash can do). He has better telepathy than Aquaman, and just statstomps Arthur. Even Superman or Wonder Woman aren't going to be able to match Thanos' sheer strength. They'll eventually be overwhelmed. Cyborg and Batman get stomped. Tbh, the last one standing is going to be Superman and it might become hard after he truly decides to stop holding back, but if you want to take Thanos out, you'll need to add a competent Green Lantern or two, and perhaps someone like Martian Manhunter or Orion.
