Horuz was a member of Yondu's Ravager Clan.
While on Morag, Yondu's adopted son, Peter Quill abandoned the Ravagers and betrayed his adoptive father and former mentor. Horuz is outraged that Yondu wanted Peter back alive and pointed out they should have delivered Peter like they were hired to do. He also pointed out that he had gone soft on the boy.
He was later killed on the Battle of Xandar.
