Cobra

Cobra is a female SandWing and the mother of Qibli, Sirocco, and Rattlesnake. She, along with Sirocco and Rattlesnake, bullied and abused Qibli. She was a top assassin who many respected, but she hated dragonets. Some were confused why she had dragonets instead of getting rid of them. Qibli tried to garner her attention a lot of times, but she didn't care for him or his siblings. She showed no love to her dragonets and even sold Qibli away. She is shown to be very dedicated to her job, as that she killed members of her own organization to trick Qibli (unsuccessfully).

Darkness of Dragons
After Qibli left, Vulture, Cobra's father, imprisoned her to get his hands on her dragonets, to make them join his Talons of Power Organization. He trapped her in an oubliette until Qibli came to Vulture's fortress to look for Ostrich. When Cobra was freed by Qibli, she told him to escape that night with her. Cobra stopped herself from calling Qibli "lizard", and even tried to kill her other two dragonets for trying to stop her escape. It was later revealed/deducted by Qibli that Cobra and Vulture were plotting against Qibli, by making it seem as if Cobra had been trapped in the oubliette for years, although it was only been less than a day. Vulture and Cobra had set a trap for Qibli, trying to make him lead his mother to Thorn's stronghold. Cobra was arrested by Thorn and Qibli.
