Character Type: Canon
Name: Greta Hayes
Alter Ego: Secret
Age: 15/16
Hair Color: Blonde
Eye Color: Blue
Moral Compass: Good but with a tendency to slip into evil.
Affiliation: X Young Justice, X Titan Now a New YJer
Known Relatives: Mother: Insane due to loss of family.
Father: Committed suicide on Apokilips whilst being possessed by Harm .
Step Brother: Harm. Her murderer. Currently a titan.

Known Powers: Her constant form is now solid, she can change into smoke at will.
She still has the ability to change shape, fly, etc but a new power is to create things with her mists and make them solid. (Like she can create the shape of a hammer in her hand, become solid and the hammer is now made of wood and metal.) She can only create items of a certain mass, her limit is yet unfound..

Original Powers: Manifest herself in a smoke-like gaseous form. Can in a sense, slip though the smallest cracks and use her vapours to obscure vision.
She has not demonstrated the ability to change her form into toxic fumes as the D.E.O. claimed. She is a Warder, a gateway to the Abyss. She is able to send people to or through the Abyss. (IE, she sent Despero TO the abyss but she transported YJ team THROUGH it, thus saving them from the explosion that destroyed Happy Harbour. They weren't to happy.)
It is theorized that Secret's gaseous form has a violent, explosive reaction to potassium chloride. Pure oxygen will render her unconscious. Young Justice's interference prevented the D.E.O. from ever testing these particular theories.

Original Weaknesses: Her gaseous form is unaffected by most attacks - only elemental attacks like ice and especially electricity seem to hurt her. (Note. The ice was from when hell froze over; her link to the abyss caused her smoke to freeze. She was killed by electricity so she is weak to it.)

Known Weaknesses: She is now vulnerable in her human form, she can be knocked out, gassed and even killed!
If she uses her creating power too much it drains her and she cannot switch forms.

Most recently: Greta was returned to the Abyss due to an accident involving her Step-brother and was remade into her ethereal form.
The difference was that the first time this happened she was deceased, the second time she was actually alive so her link to the abyss was reconnected differently. She is no longer a pawn for the powers-that-be, choosing who she ferries through her link.
After she got her ‘powers’ back, Greta returned to her new school, Elias High, along with Wonder Girl, Cissie and Shinigami.
She blocked out having returned to the abyss but after she began to visit her mom in the psychiatric ward, she would slip into her old self at various points.
It turned out Darkseid had brainwashed Greta’s mom to influence the evil in her daughter.

History: Greta was a fun, loving child who lived as an only child with her parents till she was 6. The Hayes then adopted the 8 year-old William. Something about him scared the young Greta completely.
Her next memory is of Billy, when he murdered her. He pushed her stereo into the bath and electrocuted her.

Billy had decided his ambition in life was to become the greatest super villain there is - and he gained his super powers by sacrificing Greta to a demon. On the threshold of Death, the Lords of Light decided to balance her step brother's new evil power by changing her into what is known as a warder. A warder is a spirit guide who is responsible for guiding the dead to their resting place, and dragging the unquiet dead to the Abyss.

Secret's next memories are of the D.E.O. orphanage facility; she had apparently returned from the Abyss as a ghost. She was studied here until they decided she was too physically dangerous - and more importantly that she knew too much. Secret escaped on the way to the Wabe facility, a location designed to "dispose" of problem children. Robin, Impulse, and Superboy managed to capture her, but the boys sympathized with her plight and instead decided to help her, Robin arranged circumstances so that it appeared she was killed by accident when she was returned to the D.E.O. All three boys lied to their mentors to protect her.
Not knowing what to do or where to go, Secret decided to join Young Justice becoming the added girl power it was missing along with Wonder Girl and Arrowette, who gave Secret her new name "Suzie". She found happiness being a part of Young Justice and has proved herself to be a loyal teammate.
Secret has since learned more about her origins through Darkseid and the Spectre - including her real name, Greta. Secret has also learned there is a darkness in her soul.... a darkness which especially intrigued the demonic Darkseid.

When none of her Young Justice teammates helped her save her father from death row (Aside from Slo-bo but he doesn’t count right now because he just did it for the kicks.), Greta felt hurt and betrayed. Darkseid took advantage of Greta's vulnerable state and turned Secret to the dark side. She began to enact revenge on all those who have wronged her throughout her young life including her Young Justice teammates (MWAHAHAHAHAA And Spoiler.). Robin eventually reminded Secret of her humanity and she broke free of Darkseid's control. Darkseid punished Secret with the worse thing he could imagine: restoring her humanity so she was forced to live the life of a normal girl. Which was actually quite good because this was Greta's fondest wish. So sometimes its nice how things work out huh?

Recently Greta now attends St. Elias' School for Girls along with Cissie Jones-King, Cassie Sandsmark and the fallen angel Shinigami.

Most recently she has been dating the Boy wonder, Robin. Also known as Tim Drake
