Zagstruk is a disciplinarian Stormboy Boss.
He leads a squad of Stormboyz called the Vulcha Squad. He has a famously bad temper and his squad are usually more scared of his temper than their enemies. His squad gets its name from his personal aircraft - an enormous red Fighta-Bommer called Da Vulcha. After an unfortunate encounter with a Space Marine Dreadnought resulted in the loss of his legs, Zagstruk had Bionik replacements made, known as 'Da Vulcha's Klaws. Zagstruk's preferred method of attack is made all the more deadly by these sharp, heavy, metallic legs (which have much in common with an Ork power klaw). When he charges, he leaps feet first at his foe, driving his bionik legs into his victim with enough force to pulp bone and smash ceramite.2
