Chapter 10

DEO Headquarters

Percy stood out on the balcony, everyone was in position; he waited for the signal from Clark to come to his aid. To fight the son of Darkseid, to fight Kalibak. However, the last daughter of Krypton preoccupied his thoughts. He didn't like to fight or argue with her, but he was right, wasn't he? He shook his head before the sound of the sliding glass doors behind him made him aware of a new presence on the balcony, a certain second in command of the DEO.

"You seem a little impatient," Alex observed.

Percy frowned. "I was a demigod; I guess the ADHD that goes with it can still surface its ugly head sometimes."

Alex nodded, her brown eyes focusing on Percy's furrowed brow. "The wait isn't the only thing bothering you, is it?"

"You a mind reader now, I thought that was J'onn?"

Alex laughed. "Yeah, that's him, but I'm good at reading people, even gods."

"So, what do you think is bothering me?"

"Well, the way Kara stormed out of the DEO, I'd say you two had a fight." Alex's eyes narrowed at the thought.

"Come to lecture me on arguing with your sister?"

Alex walked to the balcony, placing her hands on the railing. "I don't like to see my sister upset, but she only gets this upset when she is worried about someone or when she really disagrees with something important. So, which is it?"

Percy smirked. "Why not both?"

Alex frowned. "You don't get to make jokes about my sister."

Percy turned toward her. "I wasn't making a joke, Alex."

Alex shivered at the way he said her name. She needed to be careful. She knew Percy was a good person, but he was also a nearly all-powerful entity. "Then what happened? I want to know."

Percy turned back to look down at the city streets below them. His dark hair was swept to one side, but his glowing sea green eyes were filled with power, but with sadness as well. "She does not agree with my plan."

"To lure Darkseid to Earth. To bring the battle to a head quickly, so that the planet isn't in a constant state of war."

"She doesn't disagree with the overall plan, just the lure."

Alex's brown eyes widened in realization. "She doesn't think you need to destroy Kalibak?"

"Yes," Percy agreed. He rubbed the back of his neck. "Kalibak is a god himself; he cannot die permanently, not like a mortal, but she still thinks it is wrong."

Alex nodded. "Kara has strong convictions; it's one of the things that makes her a great hero."

"It's one of the things that attracted me to her, in addition to her loyalty," Percy admitted.

"So, what are you going to do?"

Percy chuckled, but it wasn't a happy laugh, it sounded strained and much darker than Alex liked to hear. "That's the million dollar question, isn't it?"

"We all have faith in you, even Kara. You'll do what's right."

Percy turned to look at Alex. "I appreciate the support and the faith that all of you show. In the past, I would save my enemies. I never wanted to take a life, except for monsters; for the most part, they never gave me a chance to save them. I'm afraid Kalibak will do the same. I don't want Kara to hate me for it."

Alex placed her hand on his shoulder. "She won't, if it's what you have to do, she will understand, eventually."

Percy frowned. "That's the thing, eventually is a long time for her."

"Don't worry over it, do what needs to be done. Kara does forgive those that she loves. She forgave me for killing her Aunt to save J'onn. She will forgive you." Alex let go of his shoulder before she walked back toward the door.

"Alex," Percy said. She stopped in the doorway, turning around to look at the god of stars. "Thank you for listening. Sometimes, in this godly form, I forget how good it is to just talk to someone."

Alex smiled. "No problem, just promise me one thing."

"What's that?" Percy looked at her curiously.

"Just love Kara the way she deserves to be loved."

Percy smiled warmly. "I love unconditionally, Alex, so that's the only way I know how."

Alex nodded before walking back into the headquarters, closing the doors behind her.

Metropolis – Millennial Park

"Clark, you sure you don't want me to stand with you?" Kara asked worriedly.

Clark smiled at his cousin's concern. "No, I trust Percy. I need to do this alone; besides, you might scare off Kalibak."

"Yeah, you're probably right; I don't want to steal your thunder," Kara said sarcastically.

Clark rolled his eyes. "Go find the others. I'll be fine."

Kara nodded before she flew off, back to one of the buildings that overlooked the park.

Clark walked over to a nearby stone bench, sitting down to wait for the son of Darkseid to arrive.

Suddenly, a white circle of light followed by other light circles that flowed through and around the other circles, forming a strange tube of light and energy. When the light faded, a large man with gray skin and long black hair walked out of the portal. He was holding a four-foot long, metal mace with a glowing light on the end of it. The portal closed behind him before he spotted the Man of Steel sitting on the bench.

Kalibak frowned at the sight of the Kryptonian. "Kryptonian, I have come to end you."

Superman stood up before he walked toward the son of Darkseid. "You can try, Kalibak."

Kalibak's eyes widened. "How?"

Superman smiled. "I have a friend; he knows a lot of things."

"No matter, your death will pave the way for Darkseid's reign."

Superman's blue eyes narrowed before he flew forward to strike Kalibak, but he was met by the working end of Kalibak's mace. The weapon struck Superman in the chest, lighting up Superman's body with electricity. Superman's blue eyes lit up before Kalibak spun around striking the Kryptonian again, sending Superman's body flying back into a stone wall, crushing the stone into rubble.

The corner of Kalibak's mouth turned up into a strange smirk. "Yes, Kryptonian, put up a fight."

Superman knocked the broken stone off his body. He turned quickly, unleashing a blast of heat vision, striking Kalibak in the chest, knocking him back, but he was still on his feet. Kalibak raised his hands in front of his chest, blocking the heat vision with his armored forearms. He began to walk forward, pushing Superman back as he moved. He nodded his head before three flying insect-like creatures flew forward, sending three blasts of fire from their mouths toward the last son of Krypton, engulfing the Kryptonian, distracting him long enough for his heat vision to shut down.

Superman raised his head and fired his heat vision again, striking each creature, sending them tumbling through the air before crashing into the concrete plaza below. Superman turned back to Kalibak, but it was too late, the son of Darkseid was already moving forward, swinging his mace, striking Kal-el in the face, the electric shock from the mace, making Kal-el's skeleton light up from beneath his skin. Kalibak swung again, striking Kal-el across the other side of the face. Superman was sent careening across the lawn of the park, striking the ground in several places before his body dug into the turf, creating a long and deep gouge in the soil.

Kalibak smiled, holding his mace with both hands in front of his chest, looking up into the sky to see who else would challenge him.

"Nice show, Gruesome," a voice mocked from behind him.

Kalibak turned around to see a strange glowing man behind him. "Who are you?"

Omega smiled that crooked smile that women found attractive and enemies found mocking. "The name is Omega."

"Omega, huh! You come here to take a beating, like that Kryptonian?"

"Something like that," Omega said.

Kalibak swung back his mace in a ready position, like a baseball player holding his bat. "Bring it."

Omega smiled before moving forward at the speed of light. Kalibak's eyes widened, but it was over before the son of Darkseid could react. Omega struck the general of Apokolips head on, his shoulder striking Kalibak in the chest. The hit was so fast and powerful that Kalibak dropped his mace on the ground. Kalibak's body was sent flying backward before he too struck the ground creating a deep gouge in the turf.

Kalibak sat up, groaning as he rubbed his head. He was dazed for a moment before he shook himself and stood up quickly, jumping up and out of the hole in the ground, stopping in his tracks when he spotted Omega, leaning against a tree with his arms crossed in front of his chest. Kalibak's eyes narrowed. "What are you?"

Omega smiled. "Well, what's the fun in telling? Why don't you guess?"

Kalibak growled. He touched a button on his belt; a light began to flash. "This world will be Darkseid's." Over one hundred of the insect-like creatures appeared from multiple portals that opened up in the park. Omega closed his eyes, telepathically broadcasting a message to the newly formed Justice League, a name which was coined by Clark and Barry. The team appeared, hitting the creatures head on. Kalibak's dark eyes glowed as anger flooded his body. "You cannot win."

Omega chuckled. "We'll see about that," he walked forward Kalibak swung a fist at the primordial of the stars; Omega dodged the strike as well as the ones that followed before he sent a punch toward the son of Darkseid, striking the General in the face, knocking him off his feet. Kalibak spits out a glob of dark blood. "Why don't you call your Daddy?"

Kalibak frowned. "You wish to fight Darkseid, himself?"

"I wish to kick Darkseid's ass."

"You are not worth his time."

"So, he's a coward then?"

"You dare call the Lord of the Universe a coward."

"Yes, I do."

Kalibak pulled a small weapon from the back his belt; it was a silver cylinder with a red glowing orb on the end. He pushed the button on the weapon, pointing it at the Primordial. "You will die," he said as a red beam struck Omega; a loud explosion echoed throughout the park. A shockwave moved out from the blast, leveling every structure and tree within the park. The red light and the dust cleared to reveal Omega, standing unscathed, except that his eyes glowed a dangerous red color. Kalibak's eyes widened. "That's not possible."

"Damn straight it's possible," Omega said as he unleashed a blast of energy that struck the son of Darkseid, holding the god of Apokolips in place within a ball of energy. The ball of energy imploded on itself sending another shockwave out. When the dust settled, Kalibak laid flat on the ground, his body steaming from the heat of the blast.

Superman and Supergirl landed on either side of Omega. "Is he dead?" Kara asked worried that Omega had gone too far.

Omega shook his head. "He lives," Omega said as he walked toward the fallen god. He grabbed Kalibak by the front of his armor, lifting the large being in the air easily. He looked over the god's armor until he found what he was looking for. A round, orb-like device, it was also silver in color. Omega grabbed it with his left hand, concentrating on the device.

"What is that?" Clark asked.

"It is a Boom Tube activator," Percy replied, his eyes closed as he thought of the destination that he wanted. A circular orb of light and energy appeared in front of them. "Darkseid!"

A few moments went by. "Who dares call Darkseid?" a deep and gravelly voice said from the portal.

"I, Omega, son of Chaos, son of Rao, son of the Presence, son of the Source calls you out dark god. Face me for the fate of Earth."

"You have courage, child of the Source."

"I have much more than that."

A loud chuckled came from the portal before a shadow appeared, a moment later, a man about eight feet in height exited the portal. He was well built; his skin the color of basalt and coarse like sandpaper. He was bald and had a strong jaw with eyes that glowed red with immense power. He wore blue armor with a glowing omega symbol on his chest. He frowned down at the Primordial of Stars. "You have summoned your own death."

Omega dropped Kalibak on the ground like a rag doll. "Kal and Kara, go help the others."

"What about you?" Kara asked worriedly.

"This is why I was created. The reason I was sent to this Earth. Go, let my battle begin." Kara and Kal flew off, leaving Omega to stand before the Apokolips.
