From the Super Mario Wiki
State Troopas are members of King Koopa's Koopa Pack and are a sub-species of Koopa Troopas. They were featured in The Super Mario Bros. Super Show! episode "Toad Warriors", where they acted as King Koopa's corrupt police force and soldiers.
State Troopas have a somewhat odd, punk style appearance, having large, pointy and pink mohawks, dark sunglasses and shirts with ties. State Troopas also utilize various amounts of equipment, such as Bob-ombs, projectile spitting Cobrats and vehicles seemingly made of junk, such as barrels and toilets.
