Danny pushes Vlad out of the park before he brought his fist down on the Teen's back. Danny crashes into the ground and looks up to see Vlad coming at him. Danny quickly jumps back as Vlad punches the ground. Danny flew up and threw a punch, only for Vlad to grab it and slams him on the ground. However, Danny quickly fires an ectoblast at Vlad's face, knocking him back. Danny stood ready before he was grab from behind. He turns to see another Vlad holding him. He was then shocked as another Vlad punches him in the stomach. Danny fell to his knees as two more Vlads steps up.

"Really, Daniel? We had this song and dance way too many times. When will you learn that you're outclassed?" He asked.

"I don't care what you say. I won't let you rule over the Earth, The Ghost Zone, Heaven, or Hell," Danny said, looking at him.

"Besides, you're way too much of a fruitloop to rule over anything." He smirks.

Vlad growls as he goes to punch Danny again. However, a red beam hit him, knocking him away from Danny.

"A Grown Man like you hitting a younger child? I normally wouldn't care, but that is my boyfriend you're hitting."

The other Vlads turns and saw Lucifer walking up, a red aura around her. One of the Vlads tries to rush at her, but she smacks it away, causing it to disappear. Another tries to attack from behind her, but she grabs him and threw him headfirst into the ground, also making him disappear. The last two Vlads try to team up on her, but Lucifer was ready. As soon as they were close, she grabs them by the necks and slams their heads together, causing them both to disappear. Danny was surprised, but Lucifer remains calm. She then turns and threw a punch. Hitting Vlad right in his cheek, knocking a few teeth out. Vlad was sent flying before crashing into the ground. He pushes himself up and spits up some ectoplasm before wiping his mouth.

"Well, she's not the queen of hell for nothing." Vlad groans before pulling out the red gem.

"I guess I might as well use this." He said, holding it close to his body.

Lucifer walks over to Danny and helps him to his feet.

"Thanks." He said.

"He's powerful, but no match for me." She said before kissing Danny.

Suddenly, a powerful energy was felt, and both Danny and Lucifer turn to it. They saw Vlad fly up to them and looks really different. His suit remains the same, but he now had horns and a demon tail. He had claws and shape teeth. His cape was replaced with wings, and his hair looked like black fire. Both of them looked shocked, but Lucifer senses the power he was using.

"A Demon Crystal?!" She shouted.

"A what?" Danny asked.

Vlad roars at them and charges at them. Danny pushes Lucifer away before Vlad punches him into the ground. Danny gasps as his eyes widen from the power Vlad was showing. Vlad grabs him by the head and picks him up. He then punches Danny's setting him fly through the town, shocking many people. Danny crashes into a building and lay there groaning. Vlad was way stronger than before. His body aches just from the punches alone. He was sure Vlad broke all his ribs. He pushes himself up and coughs up some ectoplasm. He pulls himself to his feet and steps outside. He saw Vlad landing on the ground and roars, making the people run.

Danny stood ready and flew at Vlad as fast as he could. However, Vlad took to the skies before appearing behind Danny. Danny had no time to move when Vlad grabs the back of his head and slams him into the ground. Vlad then puts his foot on Danny's head and tries to crush it. Danny could only scream as he felt his head get tighten. Vlad smirks before hearing a sonic boom. He looks up to see a fully red demon girl with long white hair flying towards him. Lucifer punches Vlad in the face, sending him flying once more. She then turns to Danny and rolls him over.

"Danny! Are you okay?" She said in a demonic voice.

"My head felt like it was getting crush." He said, trying to push through the pain.

"You have to get out of here. Vlad is using..."

She stops before she senses the demonic power heading for her. She picks up Danny, and flew into the air. Vlad just missing them. She holds onto Danny and grows. Knowing he was too injured to fight, Lucifer places him inside a demon barrier she summoned. She turns back to Vlad, and flew right at him. The two superpower demons fought through the town, many people running for their lives. Lucifer lands a punch on Vlad's cheek, who returns with an uppercut to her chin. Lucifer kicks him in the stomach, and Vlad headbutts her. Finally, they grab each other hands, and started to push each other.

Vlad then smirks, catching her off guard. Vlad knees her in the stomach before throwing her away. He flew after her, and lands a punch each time he got close. Vlad then grabs Lucifer's foot, and started to spin her around. He let go, and she was sent flying into the barrier that Danny was in. It was destroyed and both of them landed on the ground. Lucifer got up, and notices she was laying on top of Danny. She got off him and checks on him.

"Touching, isn't it?"

Lucifer turns and saw Vlad landing on the ground, smirking at her.

"To think that I could have sought out this power years ago. A chance to finally show everyone what could happen if they cross me. Not to mention, being on pair with the Devil herself." Vlad said.

"The Demon Crystal is not something to be mess with, Vlad. Give it to me, NOW!" Lucifer said, growling.

"My dear, you have no control over me. Say hello to the new ruler of Hell!" Vlad laughs before thinking.

"Hell, why not become the rulers of all the places! Like the Earth, Ghost Zone, and even Heaven!" He said.

"Not happening!" Lucifer growls, ready to fight him again.

"Oh, and why do you care so much about my actions? You're a demon! You're Lucifer! THE DEVIL! Why throw your life away for one mere mortal?" Vlad asked.

"There's nothing mere about this mortal!" Lucifer growls.

"He was sent to Hell against his will! He's not even signed to go there when his life comes to an end! But he has done want no one has ever done before! He won the heart of the Devil! And this Devil wants him to grow and live his life! I will always LOVE HIM!" She shouted her red aura appearing.

Danny felt the aura reach out to him and was soon cover in a white one. He found himself floating next to Lucifer, who was shocked to see him. But she reaches over and grabs his hand. Danny smiles at her before Lucifer pulls him into a kiss. Her wings cover them as a bright light covers them, forcing many people to cover their eyes. When it fades, everyone was looking at a new person.

It was clearly a girl, but she didn't look anything like a demon. She had long white hair with a black bang hanging in front of her face. Her clothes look like a suit that Lucifer wears, but white inside of black. She also had two different wings. Her right was a demon's wing, and her left was an angel's wing. Finally, two long Devil Horns came from her forehead and pointed up to the halo above her. When she opened her eyes, her right eye was blue, and her left eye was red.

She looks over her body and flexes her hands.

"Interesting." She said, looking at her wings.

Vlad was surprised. He had seen Daniel's and that Angel Girl fusion into another angel, and he heard that he had fusion into other demons with the rest of the girls. The new girl was too busy looking over her body, and Vlad decides to attack while he had the chance. He flew at her at top speed, but suddenly feel something behind him.

"It's rude to attack someone when they need a minute to understand something."

Vlad turns, but was punched in the cheek, sending him flying through the town. The girl looks at her fist, and started to flex her fingers

"Hmm, very interesting." She said before looking up.

She could see many people flinch and started to back away. She looks at the people and could tell they were scared of her. She opens her wings and took into the sky, leaving a creator in the ground. She flew until she was high above the town and saw someone else heading into the sky. She could spot Vlad, who was growling at her, with a huge cut on his cheek. She smirks, causing Vlad to growl even more. He flew at her and landed a punch in her stomach. He started to throw all his punches, leaving the girl no room to block or counter. Vlad threw one more punch and saw the girl back away.

"Heh, not so tough, are you?" Vlad smirks.

The girl kept her head down before she started to chuckle.

"Tough? Oh, Vladdie, you have no idea how strong I really am."

"WHAT?!" Vlad asked, shocked.

"Your punches? They tickle, like a tiny feather." She said, raising her head.

Vlad couldn't believe it. He gave her everything he had, but it didn't even phase her. He growls and shot his ecto beams at her. There was an explosion, and Vlad waited. He started to smirks, but it fades when he saw that she was completely unharmed.

"What?! What are you?!" He asked, his voice full of fear.

"Me? I'm your worst nightmare. I'm the fusion of Danny Phantom and Lucifer. Unlike the others, I'm not a summon. I'm born of two different being untied as one." She said before smirking.

"I'm neither Angel nor Demon! I'm a Nephilim! I am ANGEL DEMON!" She shouted, letting a bright aura surround her.

Vlad backs away in shock before growling. He threw another punch, but Angel Demon grabs it. She quickly threw another punch, knocking the breath out of Vlad. She then threw another one, causing Vlad to spit up some blood. She threw one more, and Vlad could feel something trying to come out of his body. Angel Demon then threw Vlad towards the ground, making a huge creator. She flew down, and slowly walks up to Vlad, who was climbing out of the creator.

'Impossible! How is she this strong?!' He thought.

Angel Demon kept walking up to him before Vlad turns around and fires at her. Seeing the smoke covering her, Vlad took off into the sky, trying to get away so he could come up with a plan. However, he was shocked to find Angel Demon in front of him and clothesline him. She then tosses Vlad towards the ground, making another creator. She lands on top of him, making him spit out the Demon Crystal, which she grabs. She looks down at the man, that turns back to normal. A black ring appears and turns him back into Vlad Masters. She heard a few gasps, and looks up to see the people looking down at them.

She grabs Vlad, and flew out of the creator. She tosses him to the police before pocketing the Crystal. She looks around and notices how much of a mess the town was. She raises her hand and snaps her fingers. Suddenly, everything started to repair itself. The creators were filled, and the buildings were fixed up. She gave one last look at the people before opening her wings and flew away.

One hour later...

Angel Demon landed at the apartment that the others were, and steps inside. She walks towards the living room, where she saw the girls and Danny's family looking at her in shock.

"No way..." Judgement said, shocked.

"A Nephilim...?" Azazel asked, her eyes completely widen.

Angel Demon smiles before she closes her eyes. She was surrounded in a bright light before it split into two. The two lights fade, showing Danny Fenton and Lucifer full healed. Danny steps back as Lucifer shook her head.

"Augh, that was not the kind of fusion I was excepting." She said, holding her head.

Danny said nothing, only looking at her with wide eyes.

"Danny? What's wrong?" Jazz asked, worried for him.

"Lucifer...please tell me I didn't read that thought right." He asked, his voice shaking.

"What thought?" Jack asked.

Danny just stared at Lucifer, still not believe what he picks up during their fusion.

"Danny?" Maddie asked, confused.

"Lucifer, why didn't you tell me?" He asked, confusing everyone.

"Tell you what?" Beelzebub asked.

Danny took a deep breath and said something that shocked everyone.

"YOU'RE PREGNANT?!"

And done! So I brought in Danny and Lucifer's fusion and they beat up Vlad, even with the Demon Crystal he was using. And you read right...Lucifer is pregnant! She has actually been pregnant for a long time. Due to being a demon, she is able to hide and delay her pregnancy. When did she? All the way back in Phantom in Hell, during their first meeting. So, how is everyone going to deal with the fact that Danny had a child with the Devil herself? And why did Lucifer keep it from him? All answers are in the next chapter.

Also, I rewrote (more like added) Danny's and Malina's Lemon in Demon Musume.
