Aurora

Very beautiful, very dangerous. Her nuclear abilities make her a worthy foe, and if she gets pissed off her body glows with nuclear energy. Aurora was interested in Hawke for awhile, up until her tragic death. Her friends call her “Nuclear Bombshell”. As far as her death goes, she was fighting Sarah and Charlotte. Even though she put up a fight, she was close to death. As a last ditch effort, Aurora used all of her power to overload her core, causing an explosion strong enough to destroy the Hero School.

Powers: Nuclear manipulation

Weapons: “Who needs weapons when you’re a living atom bomb?”

Past
Although it is largely unknown, from what she has revealed to Hawke, she was taken by an alien race when she was 5. She already had the slightest hint of Nuclear powers, but they were very weak. After she had been the subject of traumatizing experiments, her abilities were magnified significantly. After she had achieved full power, the aliens had put her in a life pod shortly before the ship had crashed after the attack.

Relationship with Hawke
Shortly after they had met, they had discovered feelings for each other and Aurora made Hawke part of her recovery process from the trauma of her past. Before Aurora's death, she and Hawke had made love to each other, revealing her multiple scars to Hawke. One day later, she had said goodbye to Hawke one last time while fighting Sarah and Charlotte.

Aurora's sacrifice
Although Aurora had literally blown herself up, there were multiple factors leading to her decision. Aurora was fighting Sarah and Charlotte inside the school, where everyone except Hawke had been evacuated from. At first, it looked like she was going to be able to survive until Charlotte had set up an illusion for her to stop her from dodging a throwing knife from Sarah. After she realized she was hit, Sarah hit with a powerful blast of pure magic, severely hurting Aurora. Realizing her judgement day was upon her, she started to internally overload her core, causing her to glow a bright pinkish white. Seeing that Hawke was trying to get in, she had locked Hawke inside of an explosive hardened room. After she had done this, she detonated her core, which caused the near destruction of Sarah and Charlotte, the death of Aurora, and the destruction of the school itself. After Hawke had wandered to find his way, Austin and Sally had decided to make Aurora an honorary Suicide Squad member, honoring their friendship with Aurora and her sacrifice.
