Prologue
A pair of doors opened, stepping in two Onyx Guardsmen with huge rifles with bayonets, the Onyx Guardsman escorting a woman in blue and red clothing with the cape and blond hair. Out of the shadows revealed Kara Danvers, AKA Supergirl.
The soldier pushed Kara to stand into the middle of the ornate courtroom. The Onyx Guardsman unlocked the handcuffs off, letting them fall into the floor. A grimed Kara shifted her stare at the surrounding environment of the courtroom's interior and studied the people in the courtroom.
She admits these people had a severe taste for culture art and design but in an aggressive depth. Pillars decorated with unique symbols show statues of historical figures around her and paintings of a hybrid like modern neoclassical cities to politicians neither in uniform like suits on the walls.
The upper levels contained black armoured soldiers standing behind the sidelines with guns levelling down at the sizeable rounded floor. In front of the judge's flag was a trio of blue banners with the COG insignia with wings.
"Stay there." Warned the soldier before backing off. There was a sizeable crowd of military officers and scientists present and seated in the juror's room, and all eyes were on Supergirl.
Kara turned on her left to see a muscular man in full battle armour in blue linings and grey all dress down to the feet with officer insignia of Major on the armour neck with the tag name Hoffman plus a cap.
Major Hoffman crossed his arms, standing next to the rows of seats, narrowing his eyes on Kara with disdain.
The giant oak doors opened, and stepped out of the shadows were three officials in military uniforms; of an older man in his mid-50s and a young man last was an older man with a moustache wearing a black armoured chest plate.
"Chairman Tomas Dalyell," the Onyx Guard immediately saluted at their presence.
"Deputy Chairman Richard Prescott, and Colonel Loomis." As he greets the three officials in blue uniforms plus medals just already been seated in front of the judge's desk.
"As you were," the Colonel addresses. "At ease." As the rest of the Onyx guard lowered their lancer assault rifles back and returned to their post.
Chairman Dalyell stares directly at Kara while he places both hands on the table without a word as he studies her with the tense silence in the room. Colonel Loomis rises from his seat and breaks the silence.
"This tribunate is now in session. You may be many things, but I never took you as some Indie superweapon. The last thing we would use is the term alien due to your unexpected arrival from space," Loomis states.
"The accused will be denied the right to an attorney and may not question this tribute depending on your testimony," Loomis continues, keeping his eyes on Kara.
"For this special trial: You're here because you attempt to stage an act of aggression on COG soil, or you're just another hypnotical lunatic fit for the firing squad."
Shock and disgusted by that spoken statement, Kara steps in.
"What!" an outraged Kara shouts and points defiantly at Loomis. "That ridiculous! Unbelievable! That never happens, mister." The Onyx Guards raised their rifles with fingers on their trigger.
Reaching for his sidearm. "It's Colonel Loomis, woman," Colonel Loomis snaps. "Watch your tongue, and show some respect! Now stand back down."
Biting her lips, "Everyone calms down, please I can explain what happens-" Kara states as she maintains her composure.
"Do you really think that you have every right to endanger the people of Tyrus when you came down from the skies if you are some god," the Chairman hushes as he maintains his own calm tone. Kara turns still as the Chairman continues. "Destroying the legacies of our ancestors and the Allfathers's tireless commitment upon building the foundations that held the Coalition of Ordered Governments."
Pointing the finger at Kara, "Our civilization is at risk since you arrived. You put me in an uneasy situation if you have any idea this position you put me in."
"No, Mr. Chairman-."
"Chairman Dalyell," Dalyell corrects.
"Mr. Dalyell, I would never want to take your home away and all your people," as Kara takes a step forward, "But what's the point of not hearing me out for a minute. If I tell you, none of you will believe me. Only, I can explain what really happens that doesn't involve destroying everything you love."
A murmuring is heard around the courtroom except for the officials who study her. The officers twitch for their sidearms, and the scientists ready begin to record notes.
"Then enlighten me, Kara Zor-El. Shed some light on the circumstances," the Dalyell lends forward. Kara swallows unobtrusively then wonders what and how on Earth she got into this royal mess.
Flashback
Week earlier
Fort Rozz,
Planet Earth
"I'm going to fly Fort Rozz into space myself. It is the only way," Kara is standing in front of the console inside the bridge of Fort Rozz. The intercom was connected to a secured channel to the DEO's headquarters. "To get Myriad right off the planet."
"That is not an option, Kara," Alex objected. "Once you are in space, there is no atmosphere; there is no gravity. You wouldn't be able to generate thrust. You wouldn't be able to breathe. You would be able to get back." Back at the headquarters, Alex remained uncertain about her sister's own life and the rest of the planet. Desperate to find a way. "Kara, listen to me, and I can have Max."
"There is no other way," Alex protested as she realized Kara would do the unthinkable. Sacrificing herself.
"Kara, listen to me."
"I was sent to protect Earth," Kara said in a bittersweet tone. The realization of the unthinkable settling in "And that what I am going to do."
Filling with emotions, Alex shook her head as Kara continued with chokes of feelings, "I need you to promise me something. I need you to tell Jeremiah that I never stop wearing your glasses. He needs to know that you and Eliza gave me a great life."
Kara took a moment to consider her life growing up in the Danvers family, the moments that brought her adopted family together. Kara never imagined the pouring love given to her since her childhood. Her mother, her sister and her adopted father, even all the people that became part of her life.
"I never thought I would be able to find it outside of Krypton," the two sisters shed tears. "He needs to know but everything I did. It did come from you being my sister."
"You taught me, Kara," Alex remarked. Alex couldn't lose her, and the DEO agent thought there was another way when time is running out.
Kara sighed profoundly, knowing there was no coming back. The myriad signal was almost up to the critical stage and growing until everyone's skulls across Earth would burst.
"I want you to have a good life. I want you to be happy." Kara reaffirmed as she filled her words with a sense of bittersweet, "I want you to find love. I want you to do the things that being my sister kept you from doing."
"Promise me." Kara pleaded as she let the tears flow down her cheeks. "I need you to promise me, Alex," Kara begged softly again. "There isn't much time."
Alex sniffed and squeezed her fist, ignoring the pain in her head, "I promise," she choked out.
"Good," Kara nodded as the last tear poured down her cheeks. "I have to go now."
"Listen," Alex glazed at the Starfighter pod in the command centre before turning to the console. She wouldn't let her sister die like this in this most desperate hour to save Earth. Alex was her adopted sister and the last member of Superman's people as well as his family. Nothing can break that bond between the Danvers sisters like this.
"I love you, Kara," Alex whispered
"I love you too," Kara replied.
"Kara? Kara?" Alex repeated as the intercom between the two sisters was shut off.
A Sphere like coiled space station slowly lifted off from the ground, Supergirl pushing the massive station with all of her might. As she was in midair with the station above her head while she struggled, she reflected on her own life with the Danvers family, who took her in as a child. As a hero, she endured her ground and overcome the trials throw at her.
Plus, the people that became part of each other lives, such as Winn, Alex, James, Cat and J'onn (Hank). She made the ultimate difference across National City and the people, too, stopping criminals to aliens who attempt to harm innocent people, saving lives and halting disasters in a blink of an eye. Then she couldn't stop thinking about her only family Clark Kent but along with the few who escape Krypton's destruction. Clark was all she had, and she realized she never imaged if Clark would be so proud of her for becoming the hero she meant to be.
As the last of the tears shed down while she and the station were exiting the atmosphere of Earth. Once she pushed the station away, moreover, it would block broadcast the endless wave for good. But this time at the cost of her own life.
J'onn, in his manhunter alien form, watched as Fort Rozz dissented from the skies behind him on the ground was half torn Imago and a defeated Non on the ground.
Non groaned as he leaned back up from the ground, ignoring the pain from his blind eyes after the battle with Supergirl.
"Crave fool," Non sneered before he passed out. J'onn looked at Non for a moment and stare at the skies, then realized something was wrong.
"Kara!" J'onn shouted.
Back at the DEO headquarter, every agent, soldier and personal gripping their heads in agony as the myriad wave reached the critical points even Lucy Lane and General Sam Lane lending against the console. Lucy prayed that a miracle could happen as she squeezed her father's hand tight.
Inside the fort main control centre, a console terminal was beeping rapidly, and its coding set for self-destruct. An unaware Kara didn't know that Fort Rozz would become a trap for her. While in the atmosphere away from the Earth's surface, Kara pushed what is left of her strength and breath to shove away the massive space station before her body lost oxygen and her eyes fading into darkness.
Her only thoughts were that her Fort Rozz would be out of reach from Earth.
As she floated away from the station towards the planet. Half of the Station exploded in a fiery bang. The blast engulfed together with the young Heroine.
A starship sped towards the station in the atmosphere, Alex inside the cockpit pressing against the controls, desperately trying to reach her sister.
"I am coming to get you, Kara," Alex muttered in her breath, drastic to bring her sister home. As her pod came close from reach the station, but suddenly, she witnessed the entire station igniting into a ball of an inferno. The shockwave knocked the pod off courses, and the last thing that happened was her pod went spinning down back the Earth's atmosphere.
Alex's eyes blinked and flickered while her head was ringing, staring up into the sky. "Kara?"
It was J'onn. He pulled the hatch screen off the pod and helping Alex out of the pod. "J'onn, Kara is still out there," Alex cried, but then she saw the distant burst of light flicking in the atmosphere.
"No! Kara, oh god..." Alex choked as she wrapped her arms around J'onn as she broke into heartbroken sobs.
"KARA ! OH NO! NO!"
Dropping down to her knees, Alex cried the loss of her sister while J'onn smoothes her on the shoulders. As his heart sink, J'onn looks up at the skies with sadness and mutters Jeremiah's prayer for forgiveness.
Later, National city was never the same when the entire world learns about the sacrifice of Supergirl. Those who knew Kara were never the same.
Later National city was never the same as the entire world learns about Supergirl's sacrifice erupted with grief and mourning for Supergirl who gave her life to save Earth.
However, Supergirl did not go out quietly in the night.
