Third POV
As a rift appeared over the Earth as a hand punches through as it grabs the rift to bust open as a person walks through as a girl with blonde hair with a sinful goddess body that was busty, fit, and athletic appearance came out wearing a black suit with the Red S on her chest with a golden flame symbol on her forehead.
Kara POV
I see, I am back, my training was worth dealing with the Phantom Zone.
Kara: Time hasn't passed that long, maybe a month or two since I was sent to the Phantom Zone, good cause it's time to make my move.
I flew to the Earth as I reached the ground to land in the middle of the street as my red hooded cape covered my face.
Kara: Bring me the Justice League.
I sent out a telepathic message throughout the entire world as Martian Manhunter could hear it clearly.
As then they were teleported down in front of me as I look at them.
Kal-El's face I see as I'm not in the mood to see him.
Kal-El: Who are you and why do you have that symbol?
Kara: Wow Kal-El, you really don't remember me, and you took your time putting me in the Phantom Zone with the rest of you traitors.
Kal-El: K-Kara.
Kara: In the flesh, but I look different cause I have a need to punch you in the face.
Kal-El: Kara listen, we can't do this here.
Kara: Your afraid of collateral damage, didn't stop you for beating me into the ground in front of everyone.
Kal-El: Kara, stand down.
Kara: You failed Kal-El, you sacrificed the last of your family just to be the only Hero, well you failed along with these so called heroes.
Batman: Enough talking.
He threw a battarang at me as it's edges are Kryptonite as I caught it to move passed them at incredible speed that not even Barry Allen could see.
Kara: Cute Batman but I'm afraid Kryptonite isn't going to help you, I've built up an immunity to it.
They saw I was behind them, even Barty was shocked he couldn't track me. They saw I was holding Kryptonite no problem at all which one of there defenses to stop me is gone.
Flash: Great, Kryptonite doesn't work.
Green Lantern: Let's try this then.
He constructed something to hit me but as it made contact it shattered.
Kara: Was that post to hurt?
I juggled the battarang in my hand up and down.
Kara: Here, catch.
I threw the Battarang at Clark hitting him in the chest sending him flying through the building as I checked to see the building was empty before doing that.
Wonder Woman: Superman!
She looked at me to charged at me to throw a punch me in the face but it broke her hands upon impact as she crouched down holding it.
Kara: Sorry Diana, but that won't work and neither will your powers John, just stop cause can't beat me now for what I become plus I'm asking nicely.
Kal-El charged at me, I'm not angry with him anymore but disappointed plus he still has Lois and Jonathan so hurting him isn't in the cards as he punched me in the face to break his hand like Diana.
Kara: Like I said, you can't beat me, so now that I'm out I respect you plus any other of the traitors I called my friends to leave me alone or I won't ask nicely.
The public watched as the Justice League, the strongest heroes on earth got humbled as I flew off leaving them defeated.
