An organization of modern day pirates led by "Slaughter" Shaw. They use rocket-powered battlesuits and rayguns instead of boats and gunpowder.
The Skullcrusher committed a string of acts of piracy on the Carribean. One of these coincided with Honor Guard's fight with Kroseth the Invader, but the superheroes were nevertheless able to spare Samaritan for a few minutes. He repelled the pirates' attempt on the luxury cruiser Sea Princess. ("Welcome to HumanoGlobal")
One member of the Skullcrushers, Padraig Rourke, entered into a relationship with Maria Navarro, a local woman who lived near their hidden base in Ecuador. When he turned physically abusive, Maria's daughter called Honor Guard's Emergency Contact Center. Not understanding just what Padraig was, the Center operator sent social workers instead of superheroes. Padraig murdered them, and from there it all escalated into out all-out battle between the Skullcrushers, E.A.G.L.E., and Honor Guard. After a period of siege, Honor Guard managed to invade the base. The Skullcrushers were shut down. ("Mistakes")
