Glaugan is a genetically engineered black lion that serves as a Zero's pet. It is trained to fight and assist Zero in battles as one of his Strikers. It was defeated by Maxima and likely perished alongside Zero after the battle when the ship they were fighting on burned up on reentry into the Earth's atmosphere.
