Mare is seventy five years old which for an elf is quite young and he has dark skin and pointed ears, a signature trait of the dark elves. He has golden hair and heterochromia, his right eye blue and left eye green.
He wears a blue dragon scale leather full body suit, covered by a white and gold vest embroidered with the sigil of Ainz Ooal Gown and a forest green-leaf cloak. Below, he has a matching short white skirt exposing his thighs, and on his neck is an acorn necklace emitting silver light. His slender hands are donned with shiny white silk gloves and wields a twisted black wooden staff. People outside of Nazarick, always mistake him for a girl, due to how he looks appearance-wise and the clothing he mainly wears.
Mare has a shy and somewhat cowardly personality, the kind which is a polar opposite to his sister, Aura. He often stutters when speaking and maintains a subservient demeanor during conversations. This, however, is only an outward guise and does not affect his loyalty to Ainz or his ability to carry out his duties, no matter how cold-blooded they may be.
Mare likes to sleep all day and is fond of reading books from Nazarick's library, Ashurbanipal, instead of talking with others. Unlike his sister who has an interest in collecting beast species, Mare takes an interest in collecting plant species.
Mare was created to be the brother of Aura by Bukubukuchagama. As for the reason why Mare is so submissive to his sister, Aura stems from his creator Bukubukuchagama, who apparently believed that the younger brother should obey the elder sister. (This is a known gag between Peroroncino and Bukubukuchagama).

Can store experience points and use them for experience point consuming skills with Avarice and Generosity,
Self-Sustenance (Types 2 and 3),

Shadow of YGGDRASIL: Divine Item. Mare is holding a staff that he uses when casting magic or as a bludgeoning weapon. Combined with his extreme strength, his staff can crush a human skull with ease.
Avarice and Generosity: World Item. Ainz gave this item to him so he can be protected from the effects of other World Item users. It allows the user to store and redistribute experience points, allowing Mare to use experience-consuming skills without affecting his own exp pool.
Ring of Ainz Ooal Gown: It Allows the user to freely teleport between every room inside Nazarick. Ainz him gave this ring to him as a reward for concealing the walls of Nazarick, making him the first NPC to receive this ring from Ainz.
