Led by Sergent Cloud, Squad K is a high tech government team whose sole purpose is to take down Superman should he ever be a threat to the country.
Squad K made their first appearance in Superman during the Coming of Atlas story arch. Though Squad K's first confrontation with Superman was a misunderstanding, Col. Perseus Hazard made it clear that Squad K wasn't going anywhere.
Their second appearance was made during the New Krypton Story arch, where they appeared alongside General Lane
's own anti-Kryptonian outfit, though it was very clear that Hazard was still in charge of Squad K.
As a result of their "partnership" and Gen.Lane's extended emergency powers, Squad K was forced to take on Reactron
on a mission to bring in Nightwing and Flamebird
. Once Squad K got the two in custody, Reactron Killed Hazard and several members of Squad K, supposedly by Gen. Lane's orders.
The new Squad K is completly in General Lane's pocket, and is lead by a Sergent Cloud,of which little is know.
Squad K has many futuristic weapons at their disposal. They have so far displayed/mentioned the following as a part of their arsenal:
Skinjanglers= bursts of concentrated lightning.
Screamers= High-Intensity sonics.
Microcrocollider Grenades= ????
SubSonic Curtain= ???????
