|Appeared in||Justice League: Starcrossed|
Lt. Kragger was a Thanagarian who was the right hand man to Hro Talak and a rival of Shayera's.
Once he arrived on Earth, Kragger immediately notice that there might have been something between Hawkgirl and John Stewart. He was also concerned that Hawkgirl living amongst Earthlings for so long might have compromised her, which could constitute a problem for their plans. Kragger addressed his concerns to Hro Talak, and suggested that Hawkgirl should be psychologically assessed. In respond to such concerns, Talak dismissed and admonished Kragger. However, Kragger kept a suspicious eye on Hawkgirl. He attempted to test her allegiance by trying to get her to kill an unarmed John Stewart, but she graciously refused, confirming his suspicions of her. When the Justice League escaped, Kragger hinted that Hawkgirl might have known where they were, and when she subsequently evaded the implication, Kragger used her avoidance to induce suspicion in Hro Talak. Afterwards, Kragger used the tracking device he planted on Hawkgirl to find the whereabouts of the League. He took Hawkgirl into custody for high treason, espionage and consorting with the enemy, after revealing to Hro Talak that she aided the heroes. Talak punched him in the face in frustration, yet Kragger remained proud of himself.
Kragger led an assault team to raid the Batcave, but his forces were quickly overwhelmed. J'onn scanned Kragger's mind to find out how to operate his ship. Like all Thanagarians, Kragger had strong mind barriers, but J'onn eventually managed to break through. However, such violent approach left Kragger mentally impaired.
