(Rated I for Immature)

Supergirl walked around a dark cold misty cave seeing a number of historical artifacts from various time periods scattered about on the rocks. Using her X-ray vision, she spotted a large hall in front of her. Entering the hall, she saw several demonic-looking statues with their names carved in the rock below them. They were the seven deadly sins. In the back was a circular platform with seven thrones but only one of the thrones was occupied. An ancient wizard with black skin, white hair, and wearing red robes rested on his throne. At his side was a glowing staff.

"Kara Zor-El," he addressed her.

"That's my name, don't wear it out," Kara said walking closer to him.

"I am the last of the councilor wizards. Sworn to protect the realms from the seven deadly sins," he said looking over the statues.

"Well, you're doing a shitty job then, because I've had to save this planet countless times," Kara said snidely.

"But years have passed and I have grown weak. That's why I seek a champion to inherit my magic," Black Gandalf said to her.

"That's why I'm here," Kara smiled.

"With this staff, all my powers will become yours," Black Gandalf said to her.

"Alright, hand it over," Kara said reaching for it.

"But first, you must demonstrate that you are pure of heart," Black Gandalf told her. "And strong in spirit."

"Look, I'm the strongest being in the universe so just hand me the staff already," Kara said impatiently.

"He lies," one of the statues said to her.

"Oh really?" Kara said offended.

"Don't be his champion. We can give you power. Take the eye," the statues said referring to a glowing orb on the other side of the hall.

"Are these statues really talking to me or am I high as balls right now?" Kara asked.

"We are real. The seven great sins and we are deadly," they all said to her.

"Is there a reason why I can't have both powers?" Kara wondered.

"You are either with them or with me," Black Gandalf said.

"Ah, the jealous type," Kara realized.

Kara went over to the orb to touch it. "So shiny," she said mesmerized by it.

"No, don't touch that," Black Gandalf scolded her zapping her hand with his staff.

"Ow," Kara wrung her hand.

"Only the purest of hearts can resist their temptations but you will never be worthy," he said pissed-off.

"No possibility of redemption? I'm just fucked?" Kara asked not taking him seriously.

"You are unworthy of my power," Black Gandalf said sternly.

"Look, I don't have time for your bullshit. I have a Crisis to deal with, right now, and I need all the power I can get. As it happens, I have a weakness for magic. So, you're going to make me the badest witch that ever lived or I'm going to send you back to the Marvel dimension where you belong," Kara threatened.

"You threaten me in my house?" Black Gandalf glared.

"I think I just did," Kara smirked. "Your need to have pure heroes has made you waste away in here for who knows how long. As a result, catastrophes, plagues, wars, and so forth have happened under your watch. No hero is pure. Grow the fuck up," Kara said condescendingly.

"Begone, foul bitch," Black Gandalf sent her away with a flash of his staff.

Shazam!

A few days later, Supergirl was at the DEO to bother Alex with her problems. "Today, I wanted to throw my board members out the window," Kara said to her.

"You're not getting any sympathy from me," Alex said, envious of her success.

"I have discovered fifty-four cases of people suffering from the same delusion you experienced," Brainiac 5 said to Kara.

"It wasn't a delusion. I was fucking there. It's a real place," Kara insisted.

"This is interesting. We have a situation in Philidelphia," Brainiac 5 said, showing video footage of a man in a red suit, white cape, and yellow lightning bolt on his chest.

"That symbol. He's the champion?" Kara scoffed.

"He must be pure of heart," Brainiac 5 reasoned.

"This is bullshit. I mean, just look at that guy," Kara pointed out.

"Like you can talk with that silly outfit," Alex rolled her eyes.

The three of them watched as Shazam fired off lightning bolts for a crowd in an immature fashion. "You should get yourself over there before someone gets hurt," Alex said to Kara.

"Right," Kara agreed.

Shazam continued to fire off lightning bolts into the sky. One bolt inexplicably hit a bus tire causing it to go out of control on the highway. The bus driver tried to stay on course as the bus hit the concrete guardrail. The bus driver over-compensated blasting through the guardrail on the other side of the highway. The bus was now halfway suspended over the interchange by loose rebar. Shazam sped over to the site but was unsure what to do as the bus was on the verge of falling over. The bus finally dropped but was caught by Shazam at the last moment. With his super-strength, he placed the bus on the ground. The passengers inside received only light injuries from his negligence.

The oblivious passengers and news media thanked Shazam for his heroism. Supergirl landed on the pavement and immediately the crowd gave her space. She walked over to Shazam with killer intent. "So, you're the chosen one? The so-called perfect man? Pure of heart? Flawless in every way?" Kara mocked as she circled him.

"What made you so worthy?" Kara asked skeptically.

"I just want to say I'm a great fan. You look so hawt in person," Shazam said to her. "Can I have your autograph?"

"Give me your power," Kara ordered.

"I don't think so. I'm having too much fun," Shazam refused.

"You nearly caused car wrecks on the freeway and killed those on that bus. I've killed people for less. So, do what I ask or I'm going to kick your ass," Kara threatened.

"Oh snap! Alright, before this looks stupid for you, know that I'm basically invincible," Shazam said to her.

Kara punched him hard to the gut stunning him and then gave him an upper-cut into the air. Shazam came back down crashing onto the roof of a police car shattering the windshield. Shazam coughed as the wind was knocked out of him. The police kept their distance knowing what Supergirl was capable of.

"You may have magic but it's nothing against overwhelming force," Kara told him as he knelt before her."Time to transfer your power to me."

Shazam suddenly punched her to the gut hurting his hand. "Damn, girl, what are you made of?" he wondered.

"Try steel," Kara glared at him.

Shazam went for another punch. Kara caught his arm and then grabbed his throat taking him into the air. Kara took him above the clouds within an instant. "Okay, I'm sorry. I'm sorry," Shazam babbled. "I should never have punched you. My bad. Can we talk about this?"

"You grovel like a child," Kara insulted.

"That's because I am one. I'm a kid. You don't want to hurt a kid, do you?" Shazam asked her.

Kara punched him away where he quickly fell back down to Earth. Kara watched with some alarm that he didn't know how to fly. Shazam fell all the way down until he stopped himself an inch above the pavement on a highway interchange. It wasn't long before he was hit by a truck, some more cars, and then toppled over the interchange. As he was about to hit the ground below, he suddenly came back up.

"I can fly!" he said ecstatically.

Kara suddenly punched him into a building shattering the windows as he went through it. "Supergirl, try to keep the fight out of the city," Alex radioed her.

The DEO was on deck as Supergirl and Shazam continued their fight. "There are no facial matches in the database," Brainiac 5 reported as it searched for Shazam's face.

"How is that possible?" Alex wondered.

Kara punched a distracted Shazam through the pavement into the subway system. The two fought in the tunnels until Kara upper-cut him back to the surface where he landed in a mall. Kara rose from the hole she had made in the floor and looked around for her goofy target. She eventually found him hiding in a changing room.

"This is crazy. I don't have to fight this bitch. This isn't your job. You can run, right? Yes, you can run!" he said to himself in the mirror.

"But you can't hide, asshole," Kara said as she tore the door off.

Kara took hold of Shazam and slammed him through the mirror, the wall, and then into a toy store. "Get back! Get away!" Shazam said to her as he threw stuffed animals out her.

"Is this real? Is this happening right now?" Kara wondered as the stuffed animals bounced off her.

Shazam then threw a large Batman doll at her. Kara paused for a moment and then stepped over the doll. Shazam retreated farther into the store but his movements were betrayed by a piano floor that made a noise with every step. "Oh, shit," he realized as Kara ran at him.

Shazam was punched out of the store window shattering glass around him. Shazam then tried to fly awkwardly jumping at first and then flying low inside the mall. Kara shook her head dismayed and then fired heat vision at him dropping him to the floor. Kara sped over to him and then calmly walked over to the defeated Shazam. He attempted to crawl away from her on his back in a pathetic display.

"Shazam!" he shouted.

Kara looked up as lightning blasted out the mall glass ceiling showering everyone with glass. Kara quickly blew the glass back up out of the mall. She then looked back and found Shazam nowhere to be found. "Where the fuck did he go?" Kara asked herself.

"The target was seen with a boy wearing a blue jacket," Brainiac 5 radioed her.

Kara identified Freddy as he shouted for Billy as everyone else fled. "Billy, come on!" he shouted.

Kara grabbed the boy and slammed him up against a locker "Nice shirt," she said of his Superman crest t-shirt. "Where's Billy?"

"Please don't melt my brain," he pleaded.

"Well, that depends. Where is he?" Kara demanded.

Kara walked Freddy's ass over to his house making him walk on his injured leg the whole way. As they entered, Kara scanned the house for Billy. "How quaint," Kara said pushing Freddy away from her. "He's not here. Give me your phone," Kara said snatching it from Freddy.

She then dialed Billy. "Freddy, this isn't a good time, right now," Billy said to her.

"Oh, I think it is. Come home," Kara ordered and then hung up.

Kara then eyed the foster kids all gathered together on the couch in the living room. "What a diverse cast of characters you all are representing every race and age group. So, tell me, who bit the bullet and is the gay one?" Kara asked.

"What do you want?" Mary glared at her.

"Aren't you supposed to be good? You're Supergirl," Eugene said.

"Good is a point of view, young one. When you grow up, you'll understand that the world is shades of grey. Like how I have to hurt people and destroy property to acquire a power that will save the multiverse," Kara explained.

Shazam then landed in the backyard with a thud. "There's a...," Kara said and then wondered exactly what he was.

"Kick her ass, Billy!" Pedro said enthusiastically.

"Yes, Billy, try it by all means," Kara challenged.

"Let them go and I'll come inside," Shazam offered.

"You first come inside then maybe I let them go," Kara countered.

"Shit," Shazam realized and then slowly went inside.

"Good boy...because that's all you are, isn't it? How old are you?" Kara asked.

"Basically fifteen," Shazam replied.

Kara looked his face over, turning his head from side-to-side in a power-move against him. "I've killed kids around your age before back in my hometown. Kids that had already killed people or were going to. Don't think you can use your age to get sympathy out of me."

"The black wizard said I was unworthy of the power you possess. But here you are, a coward that runs from me. You're no hero, but I'm going to give you the opportunity to be one," Kara said.

"Oh yeah?" Shazam asked nervously.

"Give me the power of the champion," Kara ordered.

"Even if I wanted to, I don't know how," Shazam admitted.

"It's the staff that gave you your power, isn't it? Let's take a trip," Kara smiled.

"Don't go, Billy," Darla cried hugging his leg.

"I have to. It's what a big brother would do, right?" he said to all of them.

Kara fired her portal gun to the cave. "After you," she said to Shazam. The two then walked through the portal and entered the cave.

As soon as they arrived, Kara punched Shazam across the hall where he hit one of the thrones and fell to the stone floor. "That's for wasting my time, punk," Kara said angrily as she picked up the black wizard's staff. "I dedicated my life to truth, justice, and the American way. Unlike you, I had a real family. I had parents, a husband, a sister, friends, and children of my own. People I want desperately to protect. The fuck you got?" Kara antagonized

"You're already so powerful. Why do you need even more?" Shazam asked her.

"I need your power to stop an evil greater than you can imagine," Kara replied. "Now, touch this staff and say your champion's silly-ass name," Kara ordered.

"Maybe you should share your power. Sharing is caring, after all," Shazam said immaturely.

Kara gave him a blank look. "Say your name," she ordered impatiently.

A Batarang suddenly hit her her cheek causing her to bleed. "His name is Captain Sparkle Pants!" Darla shouted.

"What is this? The loser's club?" Kara asked as the cut on her face quickly healed. The losers were armed with a number of odd objects.

Kara advanced on the losers. "You see this crest? It means you don't fuck with the person wearing it," Kara lectured them.

Shazam quickly took the Batarang off the floor and slammed it into Kara's shoulder. Shazam then pushed Kara across the room where she slammed into the wall. "Glad I didn't sell that Batarang. Let's go. Come on," Shazam hurried the losers out of the cave.

Kara leaped back up and took the Batarang out of her shoulder. "Son-of-a-bitch," she said annoyed. Kara sped around the cave until she found Shazam and the losers. As she fired heat vision at Shazam, he and his losers disappeared.

"This is some bullshit," Kara glared and then tore out of the cave to the surface back towards Philidelphia.

Kara flew around Philidelphia for a sign. "There was a sudden energy discharge at the Booty Traps Gentlemen Club," Brainiac 5 radioed her.

"Copy," Kara said and then flew right to it slamming through the roof and entering the club. The men backed away as they saw her.

"I am tonight's entertainment. I just got one question: Have you seen this man?" Kara asked taking a picture of Shazam out of her bra.

The crowd defiantly said nothing to her. "No? I mean, I'll settle for his loved ones," Kara said.

"We're not intimidated by you," one patron said to her.

"Well, you should be," Kara glared at him. She then put her hands together and clapped knocking everyone to the floor. Kara exited the club and looked around.

"The target has entered the fairgrounds," Brainiac 5 informed her.

Kara sighed and then floated above the fair looking for Shazam. "Billy, come out. Stop using these good people as a shield. In the end, I'll find you," Kara said as she floated above the crowd searching for him.

Shazam then emerged from the crowd and flew over to her. "Now, let's try this again," Kara said impatiently with the staff in her hand.

Shazam tried to take her to the ground, but she wouldn't move a muscle. Kara then backhanded Shazam to the ground cracking the pavement. Kara slowly landed as civilians fled in terror. As Shazam recovered, Kara fired heat vision at him blasted him through several booths causing a string of fires. Shazam flew at Kara from the fire but missed her. Kara grabbed his white cape and slammed him repeatedly on the pavement. Shazam flew at her once more missing her completely. Kara took hold of his arms extending them out. Shazam struggled against her strength as she forced him to his knees.

"Shazam!" he shouted returning to his kid-form.

Billy went underneath Kara's skirt and ran off on the icerink. Kara slammed her foot down on an icerink sending Billy into the freezing water. Kara floated over the ice and then kept Billy's head down in the water. "Playtime is over, boy," Kara said coldly as she lifted him out of the water so he could breathe and then dunked him again.

Mary then fired a carnival BB gun at Kara. She instinctively let Billy go as she caught the BB. "Shazam!" Billy shouted exploding the ice rink with a lightning strike.

Kara sped all the losers into a tent and created shadow clones of herself to give the impression there was more than one of her. All the Karas' eyes glowed as if to incinerate the losers. "Stop!" Shazam shouted at her.

"Reach for it and say your name," Kara ordered him as she held the staff. "Don't make me have to be the bad guy."

Shazam knelt before her and grabbed the staff. He suddenly twirled the staff out of her hands and blasted her to the chest with it knocking her back. "All hands on deck!" he shouted to the other losers.

The losers all grabbed the staff. "Say my name," Shazam told them all.

"Shazam!" they all shouted.

Kara got back up and saw all the losers in different colored Shazam suits all grown up. "What is this? The Power Rangers convention?"

Shazam grinned at her as his fellow losers were now all super-powered. Pedro now had super-strength, Darla had super-speed, Eugene had the power of lightning, Freddy could now fly, and Mary was a jack-of-all-trades having the same powers as Shazam.

Kara looked over the group unimpressed and then swiped her staff back from Shazam. "I didn't want to hurt any of you but this idiot has forced my hands."

"Together, we will defeat you, Supergirl," Darla said boldly.

"You could multiply your power-levels by a thousand and you would still only scratch the surface of what I am capable of," Kara replied.

Kara then sped towards Darla faster than even she could react and punched her through a number of booths. Eugene fired lightning at Kara without effect. She fired heat vision back at him dropping him to the ground. Pedro leaped towards Kara and punched her hard to the gut. Kara cast him away with little effort. Freddy took to the air only for Kara to swat him back down.

"That hurt," he muttered as he came down.

Kara and Mary then went at it hand-to-hand for a brief moment until Kara punched her to the back of the head knocking her out. "You want me, come and get me," Shazam said flying off.

Kara ignored the other losers and grabbed her staff. "Enough games," Kara said to him as they entered the city.

"Can't hear you," Shazam mocked her.

"Sorry. WHAT ABOUT NOW!" Kara shouted blasting out the windows of the skyscrapers and dumbfounding him.

Kara sped towards Shazam and punched him hard to the ground. Shazam quickly got back up and the two fired at the same time. Electrical and heat energy hit at the same time in a powerful explosion. Shazam backed away hurt from the energy discharge. Kara caught Shazam's cape and rotated him around several times before throwing him into the roof of a building. Kara then landed on the roof and waited for Shazam to get back up.

"So, I don't know you but I know of you from TV and stuff. The seven deadly sins: you got them all. I've seen your pride, the way the people fear and love you at the same time. I know your wrath with all the bad guys you've killed without mercy. I've seen you beat everyone at eating contests, so there's gluttony. I know you sleep around, that's what TMZ says anyway, so there's lust. I know that when it came to orphans like me, you never gave a shit. Unless it was fun or exciting, you didn't care...so that's sloth," Shazam said bitterly.

"Keep going, I believe in you," Kara mocked.

"You want my powers even though you're the most powerful of all. You're greedy," Shazam accused. "And...," he forgot the last one.

"Envy," Kara finished for him. "Tell me, what could I possibly be envious of? You?"

"You're fucked up in the head, Supergirl. You can't form friendships and relationships as normal people can. You just abuse and discard them. What I have with my family is real," Shazam told her.

"You're right. Sometimes, I wish I was weak-as-fuck like you and have someone else save the world, the multiverse. But I don't live in a magical fantasy land. Only I can prevent the Crisis. Only I can save the multiverse. The burden falls on me because no one comes close to my power. You thought you got some good hits on me? I was merely playing nice," Kara said as she went Prime.

"Holy shit," Shazam realized as she glowed intensely.

Kara hit him several times to the torso before he could even react. Shazam fell to the ground devastated and coughing up blood. "I'll give you credit. You're nearly at the same level as my cousin. Imagine that. You were some punk-ass kid a day ago and now you instantly have the same power my cousin took decades to perfect. But now the fun is over, and I need you to touch my staff and say your lame-ass name."

"Okay," Shazam agreed finally giving up and touching the staff. "Shazam," he said softly.

Shazam suddenly lost all of his powers becoming Billy again. Kara felt a surge of power from the staff. Her uniform became black, a silver lightning bolt appeared on her chest, and her cape became white. Electricity sparked between her hands, back-and-forth. Billy eyed her with an awed expression.

"So, this is it?" Kara wondered as she felt the magical powers flowing through her. Kara then eyed Billy just sitting there.

"Now, you can save the multiverse like you said. You don't need me anymore," Billy said getting up to leave.

"Wait...this power...is weak as fuck," Kara said disappointedly.

"What?" Billy wondered.

Kara frowned and went over to him with her staff. "This amount isn't worth the trouble I put you and your family through. You can have it back and I'll write a check to your orphanage or some shit."

"Really?" Billy asked stunned.

"Yeah, what a big tease," Kara said annoyed. "This has been such a waste of time."

Billy cautiously went over to her and touched the staff. Kara rolled her eyes as she said it. "Shazam," she said without enthusiasm.

Billy got his powers back and returned to being Shazam. "Maybe, it was because you're not pure of heart," he smirked.

"I doubt that," Kara said as she punched him to the gut dropping him. "Don't use your powers for evil...because then I'd have to kill you," she said and then flew off.

A few days later, Supergirl invited Billy into the DEO. "So, I got two people that really want to adopt someone like you but here's the catch: they're two women," Kara said conversationally.

"Are they hawt?" Billy asked.

Kara frowned. "A little above average."

"I think I'll stick with the family I got," Billy smiled.

Alex eyed Kara and Billy, pissed-off. "This is a secure floor. What's the kid doing here?" Alex demanded.

"He is now officially a super-friend," Kara said brightly.

"He's the kid you beat up all over Philidelphia," she recognized.

"The very one," Kara confirmed. "Show her what you can do," she said to Billy.

"In here?" he questioned.

"Yep," Kara grinned.

"Don't you dare!" Alex rebuked.

"Shazam!" Billy shouted.

The lightning went through the whole building knocking out all the power. Immediately, the DEO was dark. "Oops," Shazam smiled awkwardly.

"My man," Kara smiled giving Shazam a high-five.

Author's Notes: Shazam occasionally gets mentioned here and there throughout Adventures. He will make another appearance in Adventures of Batwoman Season 1.5. When and if Shazam 2 comes out, there's a good chance Kara may be involved. My plan is to do Adventures of Supergirl Season 5.5, 6, and 7 next year. Seeing as how there is a good possibility SG will cameo here and there in the Arrowverse after Season 6, I may awake from my slumber to do those as well.

CW-wise, nothing past this point matters. It's all erased in favor of a new timeline where Lex was the big hero for the last 5 seasons. This is why I don't get caught up in the "what happens next?!" craze because you eventually do get to the end and there is no payoff. Imagine if, in Avengers Endgame, they went back in time to retcon the entire MCU as if it all never happened? Instead, they went back in time to an alternative universe to make their own universe better in the present by snapping everyone back. But the heroes, those left behind, and those snapped back all still have experienced the events of the entire MCU still.

Shucks, I got IT chapter 2 ready to go but it won't be uploaded until after Halloween. You know, it is a little difficult to do a horror story with characters trained in combative and stressful situations. I also boxed myself in by having Kara be completely OP. I will say this: Season 7 is going to be really scary and disturbing. I'd have to do more research on those games to figure out how it would work in a story. I did have an idea to do a parody of Bit staring Nicole Maines aka Dreamer. Apparently, the critics love it but got reviewed bombed by users.
