A couple of Magneto's goons had just torched a center for the homeless, fleeing the scene before the cops arrive. They were laughing as they believed they had escaped down an alley with many turns, but fortune had not favored them today. "What have you done?!" Storm demanded as she flew down towards them.

"Oh, shit it's Storm! Kill her!" The male said, breathing fire at her as the female rushed in, spikes coming out of her body. Using wind, Storm redirected the flames at the female, who screamed as she was quickly roasted. Storm then turned her attention to the male and brought lightning down from the sky, electrocuting him and killing him on the spot.

"You two were beyond help. You enjoyed killing the people you did." She said, about to fly away until she sensed a powerful electrical source coming her way, jumping out of danger as a man in a red suit and a weird half-cape (please tell me I'm not the only one that thinks that cape is stupid) with a lightning bolt on his chest rushed past her, his fist out, obviously meant to hit her, with electricity surrounding it. "Impressive. But tell me, who are you?" Storm asked, prepared for a fight.

"I'm Captain Marvel. And you are coming with me for killing those two." He said, pointing to the two corpses of Storm's enemies.

"They destroyed a homeless shelter along with everyone in it and tried to kill me. They deserved what they got." She explained.

"Maybe, but that's not what we do. You can come quietly, or I'll take you in by force." He said, cracking his knuckles.

"I'm sorry, but I can't allow you to bring me in. I have important duties I have to uphold." She said.

"Then it looks like we'll have to do it the hard way." The man said, rushing in.

Storm could easily tell that the man was far stronger than her and would be able to put her out of the fight with very few hits, so she knew she had to keep at a distance. As he got close, she forced him back with a powerful gust of wind, causing him to fall back and skid a few feet across the ground. He quickly got back to his feet, but then Storm sent a barrage of ice shards at him. He managed to dodge most of them, but a few of them managed to hit him, causing him minor amounts of pain, but he was still more than capable of going. He formed a lightning bolt in his hand and threw it at her, but she countered with her a bolt of lightning from the sky, canceling each other out. Storm then took a risk and flew at Captain Marvel, spinning and making herself a small cyclone, lightning shooting out of it as well. Captain Marvel became slightly nervous at this, knowing that lightning would be able to revert him back to Billy Batson, so while he was so nervous and preoccupied focusing on avoiding the lighting, Storm got within range and delivered a powerful spinning punch that staggered Captain Marvel before Storm pushed him into a building with another gust of strong wind. "You are quite strong. But you seem to be lacking in experience and focusing on your target." Storm instructed.

"I've had my fair share of fights. I gotta say, you're not bad, but you're no match for Earth's Mightiest Mortal!" He said, rushing at her again.

Storm had noticed that he was hellbent on avoiding the lightning, deducing that was his weakness. As he rushed in, she unleashed a powerful burst of lightning from her body at him, catching him off-guard, as he had not seen anyone shoot lightning directly from their body before, hitting him and turning him back into his true form: an 8 year old boy, give or take. "A child? Quite an impressive one, too. You would be more than welcome at our academy. You could learn how to fight better as well." She offered.

"Shazam!" Billy shouted, lightning coming down from the sky. However, this was stopped when Storm hit the lightning with her own burst of it from her own body, preventing it from striking him.

"So that's how you turn into the man you were before. I think it's time for you to be silent for now." She said, quickly approaching him and freezing his mouth. "I'm sorry to do that to you, but I'm no longer in the mood to fight. You may find me at Charles Xavier's school for gifted youngsters. We'd be happy to take you in. You'd be quite a valuable student there." She said, flying off, the ice around Billy's mouth thawing shortly after she was gone.

"What... Was that about?" He asked, confused.

Reasons for the outcome:

1: Storm has been shown to be quite tactical, so she could probably break down Captain Marvel's powers and weaknesses very quickly and come up with a way to defeat him. Also, she has been shown to be able to hold her own against Thor, so it's likely she could take on Captain Marvel.

2: Storm has also been shown to be both experienced and a capable fighter, whereas Captain Marvel (and most DC characters) really rely on their strength as opposed to any incredible skill. He has the wisdom of Solomon, but is still a child underneath it all, not particularly skilled or experienced.

3: While Storm would likely stand no chance physically, she has a wider array of powers than Captain Marvel, having wind, ice and lightning whereas he only has lightning and his strength. Also, regular lightning has been shown to revert Captain Marvel back into Billy Batson, so Storm's lightning should have the same effect. And after she finds out how he turns into Captain Marvel, she has several ways of stopping him from turning back into Earth's mightiest Mortal and leaving him as a child.

Next fight...

"You end now!"
