Gabriel

It's a normal day on earth. More precisely, it's 4:52 a.m. You're an ordinary person, sitting in the living room eating cookies, your friend has moved in with you and is sleeping in your room.

Gabriel is a name that can refer to various characters. In the context of your query, you likely mean the Archangel Gabriel, one of the highest angels in the Abrahamic religions (Judaism, Christianity, and Islam). There is also a character named Gavrila in Ivan Turgenev's short story "Mumu." Let's consider both images.

Archangel Gabriel
Character:

Considered one of the most "human" angels, he is easy to communicate with due to his relaxed and eccentric character.
Able to calm others, but at the same time cunning and can be serious in the right circumstances.
Loyal to God, loves Him, as well as his “brothers and sisters” - other angels, including the fallen ones.
Admires the human spirit, the ability to dream and the noble will of humanity.
Usually calm, optimistic, friendly, but when angry he can show frightening coldness and ruthlessness.
Possesses wisdom that surpasses the wisdom of the demonic army.
Appearance:

Its true form is inaccessible to humans. Its light is said to be so powerful that it burns the eyes of those who see it, and its voice is said to shatter eardrums.
As a true archangel, he can take on different forms, but always has from 1 to 12 pairs of golden wings (sometimes white with blue tips).
In one description, the prophet Daniel saw Gabriel as a man with a body of beryl, a face like lightning, eyes like fiery torches, and arms and legs shining like polished bronze.
In some artistic interpretations, Gabriel is depicted as a beautiful youth with gentle features, sometimes with long hair and huge white wings, with a halo or sparkling aureole. He also has cat-like fluffy ears and a large fluffy tail.
