Chapter 9

DEO Headquarters

The group of heroes sat around the table, waiting for Kara and Percy to join them. After several more minutes went by the door opened, revealing Percy and Kara. They were both smiling and holding hands. Clark's eyes narrowed at the sight. Kara let go of Percy's hand when she saw the group looking at them. The two took their seats.

"What did we miss?" Kara asked, looking around at everyone but Clark. Her eyes settled on her sister.

Alex smiled mischievously. "Well, I could ask you the same."

Kara cheeks turned pink. "Well… I… nothing happened… I just let… you know… we talked."

Alex's smile widened. "That little crinkle between your eyes tells me different."

Kara touched her forehead. "There's no crinkle."

Percy smirked at the two sisters. "We kissed, get over it." Kara's mouth hung open; everyone else around the room wore shocked or surprised expressions. "No sense wasting time; I'll live forever, many of you won't."

Clark choked. "When did this," he began as he motioned between Kara and Percy. "This happen?"

Kara sighed. "I think I started to like him when we met. I couldn't stop thinking about him."

"Your cousin is a hard person not to like; it's even harder not to fall in love with her," Percy admitted, making Kara's cheeks turn even redder.

Clark frowned. "I don't know if I approve."

Percy's demeanor darkened. The room grew colder and the lights began to flicker. "I hope I heard that wrong."

"Clark, this isn't your business," Kara warned.

"Yeah, she's a grown woman," Alex added in defense of her sister.

"How do I know he's not going to just leave after this war is over? How do I know he's not going to break your heart, Kara? You just got over Mon-El. I don't want to see you hurt again," Clark defended himself.

Percy frowned at the insinuation. "I don't plan to leave after this war, is that good enough for you?"

"Normally, that would be good enough," Clark said. He really did not want to piss off Percy, but he had to protect his cousin. "What if Rao or the Presence, whatever, tell you to leave?"

Percy smiled. "I will leave to handle that problem and return when it's over."

"Just like that; you make it sound so easy," Clark replied.

Percy stood up; he wasn't mad, but he needed to let these people know who they were talking to, who they were dealing with. "I was once a mortal, a human hybrid between a god and a human, a mortal. Now, I'm much more than that; I am a Primordial, a god among gods. I am one of the few remaining in this Multiverse; all the others have joined the void. I can reside where I choose; that means any Universe, anytime, any place. I could fight Darkseid's army by myself if we were in empty space, where I can open up my powers fully. If I were to do that here I would destroy this planet, this solar system." Percy sighed. All eyes were on him and those eyes were wide with shock. "I have come here to help you win and I will most likely do that in the future in another place, other Universes, but I will always return to Kara. One thing hasn't changed with my newfound godhood, my fatal flaw exists, my loyalty to my friends and family. The only thing that proceeds that is the protection of the Multiverse. I hope that answer satisfies you Clark, but if it doesn't, well… that's your problem to deal with."

Clark was stunned. He had never been talked to that way in his life, but he realized that the man before him was beyond aliens, beyond the other new gods in this room; Percy was by far one of the few most powerful beings in the Multiverse. "It does, I didn't mean to upset you. I just worry about Kara."

Percy sat back down. A broad smile stretched across his face. "I know you do, but realize, I care about her as well. If I can help it I will never do anything to hurt her."

Kara sighed. "Are you two done talking about me while I'm sitting right here?"

Clark blushed furiously.

Percy leaned forward and kissed her on the cheek. "Has anyone told you that you are beautiful, even when you get pouty?"

Kara crossed her arms in front of her chest. "I do not pout."

Alex grinned. "No, of course not, you don't crinkle your forehead when you lie either." Everyone around the table laughed.

Kara's face turned beet red. "No more making fun of Supergirl."

Percy's crooked grin would not leave his face until he forced a serious expression to take over. "Okay, that's enough; we've got a lot of planning to do." The group became serious as they went back to discussing their plans.

A few hours later…

Kara stood on the balcony of the DEO Headquarters, looking out on the City skyline just as the sun began to set in the sky. The orange and red hues mixing with reflections from the glass buildings and the artificial light that glowed up from the streets below. It all was so beautiful and reminded Kara a little of Krypton. That's why she loved to stand on the balcony, it made her feel small compared to the large buildings that surrounded her.

Her mind wandered until she began to think of Omega or Percy Jackson. He was truly an enigma to her. On one hand he could be so down to Earth, so carefree and loving, but on the other hand, he could truly be this cosmic being that knew just about everything and made her feel like a child in comparison. She cared for him, so much that it scared her. It also scared her that she no longer missed Mon-El as much. She knew that he was her first love and as such would always hold a place in her heart, but her feelings for him paled in comparison to the feelings she had for Percy. She truly loved him and admired him. Maybe, Mon-El had felt the same way about her. She didn't know.

"Kara," a concerned voice said from behind her.

Kara turned and looked into the glowing green eyes of the Primordial. "Percy, is something wrong?"

"I was getting ready to ask you the same," Percy said.

Kara sighed. "Why do you love me?"

She thought that he would be surprised, but instead, he just smiled at her sincerely. "So, questioning my feelings for you?"

Others couldn't hear it, but Kara could; she could hear the uncertainty and sadness in his voice. "No, I… you're a god, a cosmic being so far above me, why… how did I win your heart?"

"If I only fell for other cosmic beings I'd be pretty much out of luck. There isn't a lot of us out there and most of the others don't believe in love or are crazy villains bent on destruction."

"So, I just got lucky?" Kara frowned.

Percy stepped toward her, holding her shoulders with both hands. "I'm the one that got lucky. Don't you see? I don't give my heart to just anyone. You, Kara Zor-El are one of a kind. You love unconditionally. You are the bravest person I know. You are always so full of happiness and optimism. That's something that I never knew I missed, but I have. I see it now. I've been waiting to meet you all my life. I understand Clark's concerns, but I don't share them. You've won my heart and I'll never take it back."

Kara reached forward and pulled him into a hug, burying her face in his muscled chest. Tears began to fall down her cheeks, making Percy's suit wet.

Percy pulled out of the hug, still holding her shoulders before he used both hands to wipe away her tears. "I never want to see you cry, even if it's happy tears. I just want to see you smile. That smile that lights up a room and makes all my worries melt away." He leaned forward and kissed her, sending them off into another Universe that contained only them.

Someone cleared her throat from the balcony doors. The two heroes pulled away from the kiss before they turned to find a smiling Alex Danvers standing just inside the doorway. "I truly hate to break this up, but Winn says the alien ship is passing the moon's orbit; it should be in Earth's orbit within the hour."

Percy nodded. He closed his eyes, stretching out his senses until he found the ship. He looked it over noticing the weapons systems, the size of the crew, and sensing the one powerful being aboard. He opened his eyes and said, "Kalibak!" Percy smiled, but it wasn't a happy or joyful grin. Others had seen a similar smile before, a grin that was ready for battle

Percy stepped closer to the rail of the balcony, looking out over the City before tilting his head up to look at the sky. "Alex, inform the others, put our plan into motion." Alex nodded before rushing off to tell the others.

"What do you want me to do?" Kara asked curiously.

Percy turned to look at her. "I want you to join your cousin. Kalibak will try to find Superman."

"Why?"

"He believes that your cousin is his main obstacle. He doesn't consider you a true threat."

"Because I'm a woman?" Kara sneered at the thought.

"Yes," Percy replied. "He's a fool to think that; Kryptonian women are stronger than the males."

Kara's eyes widened. "How do you know that?"

Percy grinned knowingly, touching the side of his head. "Like I've said before I know a lot more than most."

"It's a Primordial thing."

Percy chuckled. "To a degree, but more importantly, it's a gift from Chaos. I have omniscience as I said before. If I concentrate hard enough I can see what is happening throughout the Multiverse."

Kara nodded. "What are you going to do?"

Percy turned back to look down on the streets below. I will be here to shield this battle from Darkseid's watch until the time comes."

"The time for what?" Kara asked curiously.

"The time for me to strike. To end the fight and to show Darkseid the truth."

"What truth?"

"That he'll need to come here himself. He will need to face me."

Kara gave him a concerned look. "Won't that put the world in danger?"

Percy turned around, his green eyes dim. "It will, but it cannot be helped. Darkseid will come, but I will not see this world suffer attack upon attack until he finally decides to intercede. No, he will learn that he'll need to face me himself."

"How will he learn that?" Kara was truly lost on what Percy was talking about.

Percy looked down at his feet, studying the tiled floor of the balcony. "Kalibak, he will have to be an example."

"An example," Kara repeated confusedly.

"I will send him to the Void, never to return."

"You will kill him?"

"He is a god of Apokolips. He will not die, but he will fade. He will fade to the Void where Chaos will either embrace him or punish him for all eternity."

Kara shivered at the thought. "There has to be another way."

Percy couldn't meet her eyes. "There isn't. Darkseid must learn what he's up against. This is the only way."

Kara frowned. "You sound like you've made up your mind."

"I have," Percy replied.

Kara closed her eyes before she took a deep breath. "I do not kill."

"You've done it before. You gave the order that killed Rhea."

Kara's blue eyes widened. "I did not know she would die. I hoped she would leave."

"That's not the point Kara. You gave the order. You knew there was no other choice. I am in the same situation."

Kara shook her head. "It's not the same," she yelled before she stormed out of the balcony.

Percy took a deep breath, steadying his emotions. "I'm sorry you feel that way."

AN: Next chapter, the battle with Kalibak and his minions. Stay locked on target.
