Gabriel is a half-breed angel-turned human, with a disdain for humanity.
At her first, Gabriel's appearance looked more like a male than female. From the way she dressed (Wearing a manly suit) and from her actions, though at her second appearance she seemed to have changed clothing, wearing a white top and white trousers. Her top was sleeveless and she had several wristbands. She does not wear shoes anymore. Gabriel has blonde hair and green eyes. Her appearance changed slightly the second time she appeared, her hair became a lighter shade of blonde and more curly.
Even though she was portrayed by a woman (Tilda Swinton), she looked sexless, just as angels are described. She has long dark-coloured wings that appear and disappear whenever she wishes them to. A half-breed's eyes also, tend to change color depending on their mood.
Gabriel seems to have the personality of a rather cruel angel. She has a disdain for some of humanity but believes that some can be selfless and noble. Gabriel's plan to bring Hell to earth is so those who are selfless and noble can rise up and be worthy of God's love, dying in selfless ways and going to Heaven as just reward. Her plan was to get the Spear Of Destiny, kill Isabelle then take Angela's body as the host of Mammon, then with the Spear unleash Mammon on Earth. So that he could build his kingdom of fire and blood. Gabriel seems to also be afraid and worried when it comes to Lucifer, seeing as even before he lost his grace he was trembling before him, he was paralyzed and hardly talking. Only calling Lucifer by his other 'nicknames'.
Gabriel seems to dislike John more than the rest of the humans and gets annoyed by the way he thinks. As seen when he said that because he had saved many people from demons, God should take him to Heaven. Though unlike John, Gabriel reacts calmly without doing violent actions and expressing anger. His reactions though were rather sadistic since he mentioned John's cancer as the reason he was going to die and go to hell for the "life you took"; referencing John's successful albeit short suicide when he was a teenager.
She could also be called sadistic when he pinned John down, and held his foot onto John's neck. She was acting brutally towards John, and even though his voice was light, almost like whispering, the way she was hurting John showed very violent intentions. Also, a while before she did this to John, she broke a deal (As mentioned by Balthazar) she had made with Balthazar when, instead of resurrecting him, she simply killed him, deporting him back in Hell when she was finished with him. That showed that she did not show any care towards his comrades.
We could say that she cared about God a lot. Mentioning him a lot and never forgetting to comment about his kindness. That love she has about her Father is also one of the reasons to why he wishes to bring the reign of Hell on Earth. Because even though God cares about humans more than anything and loves them a lot they keep on doing bad things and they sin a lot. So she says that they should find their good side and start doing good things. But to do that they should learn what true pain. Because they only learn how to work together and care for each other at difficult situations.
She does however, feel shocked and even somewhat proud of John when he refuses to shoot him.
