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.
They seem to be rather old additions to the database, so maybe these characters had some changes in there aliases and therefore different entries by now.
However, there are some characters named Strike in comic books from other Publishers.
One would be from Malibu Comics. https://comicvine.gamespot.com/strike/4005-42642/
and another from Eclipse Comics. https://comicvine.gamespot.com/strike/4005-78538/
I don't know if these profiles should be deleted or changed to the characters from these other publishers?
