Glaxe's complete appearance is unknown. Thus far, he appears a huge, white-furred Devil with blue eyes similar to that of a wolf.
According to Roen, Glax is a vulgar and vile Devil.
Glaxe's first priority is obtaining the Grimoire, tasking his son with its retrieval. By the day, he grows more impatient with Rem's lack of progress, and questions the influence the human world has on Rem. Towards Rem, he seems to bear no love, threatening to kill him if he betrays the Arlond family. Soon after this, Glax lashes out at Rem, grabbing him by his neck and face and proceeding to beat him violently, leaving Rem both exhausted and in severe pain. With Rem as his chosen heir, Glax is extremely strict and severe, forbidding a young Rem from playing as freely as Urie Sogami did. When Rem questions why he doesn't feel jealous of Urie's freedom, Glax states that it is because the heir of the Arlond family has no need for questions.
Glax is the Devil that sealed the Devil King Maksis away, taking over his position as King. Although powerful, the Devils' powers are weakening, implying that Glaxe's urgency to get the Grimoire for himself is to restore his powers, and subsequently the Devils' power as a whole.
- Given that the ram represents Rem, it's possible that Glaxe's form resembles a ram's.
- His name is revealed in Roen's monologue from the CD Single 6, ROEN.
