Gabriel is a half-breed angel with a disdain for humanity.
At his first, Gabriel's appearance looked more like a male than female. From the way he dressed (Wearing a manly suit) and from his actions, though at his second appearance he seemed to have changed clothing, wearing a white top and white trousers. His top was sleeveless and he had several wristbands. He does not wear shoes anymore. Gabriel has blonde hair and green eyes. His appearance changed slightly the second time he appeared, his hair became a lighter shade of blonde and more curly.
Even though he was portrayed by a woman, he looked sexless, just as angel's are described. He has long dark-coloured wings that appear and disappear whenever he 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. He has a disdain for humanity and believes that the only way they can be saved is through a reign of hell upon them. So that they can unite and defend with their will. He thinks that the humans who survive will be worthy enough to go to Heaven. His 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, seing 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 and, even though John wanted to stop smoking, he couldn't, Gabriel brought that up and said that because of smoking he could never go to Heaven. Because smoking can be considered as a slow suicide and suicide is denial of the gift of God (meaning life) So he would go to Hell weather he liked it or not.
He could also be called sadistic when he pinned John down, and helt his foot onto John's neck. He was acting brutally towards John, and even though his voice was light, almost like whispering, the way he was hurting John showed very violent intentions. Also, a while before he did this to John, he broke a deal (As mentioned by Balthazar) he had made with Balthazar when, instead of resurrecting him, he simply killed him, deporting him back in Hell when he was finished with him. That showed that he did not show any care towards his comrades.
We could say that he cared about God a lot. Mentioning him a lot and never forgetting to comment about his kindness. That love he has about his 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 he 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.
