Skrull Kill Krew (Earth-1600)

The Skrull Kill Krew are a group of super-soldiers enhanced by an unknown organization with Skrull DNA to develop special abilities to combat any threats posed by Skrulls.

Origin
The individuals who would become the Skrull Kill Krew were unwilling volunteers in a project to create brand new super-soldiers, similar to Project Rebirth, to combat the growing threat of Skrulls on Earth as a result of the Secret Invasion.

The volunteers were each injected with a serum made up of Skrull DNA, resulting in the amalgamation of the Skrull's adaptable DNA code into human cells, resulting in a condition called Skrullovoria Induced Skrullophobia.

Formation
The injected individuals gained the ability to shape-shift like a Skrull, but also developed an intense irrational fear and hatred of the Skrull. This was intended as a way to "fight fire with fire" against any Skrull threats.

Only a small number of people were injected, and many did not survive the initial stages of injection. There are several people who’s effects proved slower than others (but technically still dying) were recruited into a team by a man named Ryder.

Let loose
Eventually the organization let the newfound team loose, fueled by their fear and hatred of Skrulls to kill any Skrulls in their way. After the events of the Invasion, the media controversially considered the Krew's actions as acts of genocide, while xenophobic minorities praised them as heroes for taking action against them.

Spider-Man tried to defend a Skrull mother and her child from being hunted by the Krew, resulting in a fight that prevented them from killing the innocent Skrulls and scolding Spider-Man as a "Skrull lover" and a traitor to humanity, earning him their animosity.
