Kara (Earth-X)

"The world isn't made better by protecting the weak, it's made better by getting rid of them"

- Kara to her Earth-38 doppelganger.

Kara known as Overgirl, was a Kryptonian Nazi SS General from Earth-X and the leader of the New Reichsmen. She was also the wife of the late Führer Oliver and de facto co-leader of the New Reich. Together with her husband, Kara ruled over the Earth of Earth-X.

She was resurrected years later by Lex.

Early Life
Kara was adopted by a family who presumably indoctrinated her Nazism beliefs of being the ideal of Nordic perfection, She eventually killed her adopted sister, That, along with her status as an alien and having blonde hair and blue eyes, desirable Aryan traits in Nazism ideology, helped Kara move up through the ranks in the Schutzstaffel of the New Reich. Kara eventually became co-generals with Führer Oliver, whom she fell in love with and married.

Crisis on Earth-X
Overgirl and Dark Arrow, now in an alliance with Eobard Thawne of Earth-1, launched an attack on the wedding of Barry Allen and Iris West, which Kara Danvers and Oliver Queen, their respective doppelgängers, was attending. Overgirl used her heat vision to incinerate the minister and proclaimed "peace is overrated" as their forces stormed in behind her. After battling with her Earth-38 counterpart, Overgirl was subdued by a supersonic clap. Her husband took her and called off the attack. They returned to Earth-X, where Overgirl recovered from her fight with her Earth-38 counterpart and they met with Thawne, who scolded them for attacking too soon and costing Tommy Merlyn/Prometheus. As Thawne and her husband argued, Kara told them to save their anger for the heroes and reassured them that they would win.

Oliver took Kara on board the Wellenreiter (after it flew through the temporal gateway to Earth-1), where the A.I. stated she only had hours, at most, left to live. Angered by the heroes' refusal to hand over Supergirl, the New Reich launched an attack on Central City, which Kara watched from the Wellenreiter. However, the heroes were not willing to give up so easily and fought back against the Nazis. Supergirl flew into the path of their ship, taunting her. Enraged, Overgirl flew out of the window to battle her. The doppelgängers fought in the sky until the overload of solar energy became too much for Overgirl, beginning to kill her. Supergirl flew her into space, where Kara's body exploded. Kara's beloved husband quickly followed through in death when Green Arrow shot Oliver through the heart seconds later.

Final battle for the Allstone Totems
About three years later on Earth-Prime, during a fight with the Superfriends, Lex Luthor used the Fifth Dimensional magic of the AllStone to resurrect Overgirl as his ally. Overgirl helped Lex engage Supergirl in battle across National City. Their battle culminated in CatCo Worldwide Media where Mon-El arrived from the 31st century to help Supergirl in fighting Lex. Overgirl was thrown from CatCo by Supergirl and her body exploded against a nearby building, killing her once again.
