Not much is known about the S.T.E.P team, except for the fact it had been created at some point on the Skrull homeworld on Varisa's mother, Veranke. They were meant to serve as a secret police and guard to the queen, though they often worked behind the scene and had once only been comprised of Skrulls. These Skrulls were often mutants of some kind or Super-skrulls with various powers taken from other beings due to their unique shape-shifting they had. This earned them both fear and respect on top of being highly seen as a negative aspect of the Queen but no one ever was brave enough to question her motives.
