Tullk was a minor character in the Marvel Studios film Guardians of the Galaxy Vol. 2. He was a high-ranking member of Yondu Udonta's Ravager clan and remained loyal to Yondu when the rest of the clan mutinied. He was portrayed by Tommy Flanagan.
Some time after Yondu and his crew had been banished from the Ravagers after breaking the Ravager Code, Ayesha, the High Priestess of Sovereign, arrived on Contraxia in order to hire Yondu's group to hunt down the Guardians of the Galaxy and turn them over to her. Yondu agreed, and so he and his group tracked the Guardians down to the planet Berhert.
When they arrived, the Ravagers found the Milano in a state of disrepair and most of the Guardians were missing, leaving only Rocket Raccoon, Groot and the captive Nebula. Rocket set up several traps for the Ravagers, but was ultimately cornered and captured. Rocket suggested giving the Anulax Batteries to them in exchange for his and Groot's safety, a deal that Yondu accepted. Tullk and several Ravagers agreed to Rocket's proposal, but Taserface instigated a mutiny, seizing the opportunity when Yondu was shot in the head by Nebula and taken prisoner.
All Ravagers loyal to Yondu were beaten and killed. Tullk was punched severely, and dragged to an airlock on the Eclector in front of Yondu, who was tied up. Struggling to stand, Tullk pounded on the windows in an attempt to break free, but was unable to do so. The remaining Ravagers under Taserface's rule opened the hatch, and Tullk was sent floating into space, where he suffocated, froze, and died a slow death. The other remaining Ravagers loyal to Taserface mocked and laughed at him in his final moments as his lifeless body floated toward the corpses of his allies.
