Armaros has black hair and violet eyes, and has a muscular physique like that of Azazel's or Baraqiel's, with a wildish beard. He wears armor, a helm, an eye-patch and a cape, wielding a shield in his left hand and an axe in his right, with his helm and shield both having a motif of an eagle or a hawk. As a Cadre, he possesses 10 black wings.
Armaros is fascinated with the villains from Japanese tokusatsu hero programs, which explains is his weird cosplay-like appearance. He even acts like one as shown when he swung his axe at Issei Hyoudou and proclaimed he had come to destroy Grigori and that he would settle their 'score', not allowing Issei to supposedly destroy Grigori.
Armaros originally lived in the Fifth Heaven, before he was cast out by God for having sex with a human woman.
Armaros first appeared in Volume 15. He was briefly mentioned by Penemue as one of the Fallen Angel leaders who survived, before appearing in front of Issei and Baraqiel. Armaros "attacked" Issei as he was acting as a villain from a Japanese tokusatsu hero program, to which Baraqiel had to apologize for.

Armaros reappears in Volume 22 as a participant in the Azazel Cup in Baraqiel's peerage as his Queen.
