Amity Park, Future,

A ghost looks over his portal and smirks. It looks very much like a Fenton Portal but much different. The Ghost walks up and turns on a screen, showing a woman dressed in all black and keeping her face hidden.

"Misstress, the portal is ready." He said.

"Good. Remember, you are to stop my love from marrying the devil. Do what you want to her, but leave Danny alone. Understand?" The Woman said.

"Of course, Mistress." The Ghost bows as the screen turn off.

He stood and growls. It's always about the ghost boy. Well, soon it wouldn't matter anymore.

"Startup the portal. It's time to pay a visit to the past." He said.

One of the ghosts nodded, and they started the portal. However, they didn't know someone was watching them. Someone with white hair and glowing green eyes. The portal soon opens, and the Ghost smirks.

"Set the portal to the wedding date. It's time to break up a family." He said, seeing the date set to the wedding day of Danny Fenton and Lucifer Devil.

The Ghost smirks again and goes to step into it. However, one of the ghosts was blasted away from the controls, making the others turn to the noise.

"Sorry, but I want that day to stay the same."

Everyone turns and saw a teenage girl land on the ground, wearing a red shirt with no sleeves, a pair of long black gloves, and shorts. She had heels on her feet, and her hair floated around her.

"Lilith Phantom." The ghost growls.

A 14-year-old Lilith stood in front of the ghost, her eyes glowing red for a second before fading back to green.

"Shuk. Trying to break up my family again?" She said, readying herself.

"Get her!" He ordered, causing a few ghosts to charge at her.

Lilith smirks as she easily dodges the ghosts and fought back. She knew these guys were weak. She was able to take them down in no time. She looks at Shuk and smirks.

"I'm not the daughter of Danny Phantom and Lucifer Devil for nothing, you know." She said, making him growl.

'Darn that bitch! How did she even know about my mistress plan? We even made sure that Clockwork wouldn't know about it!' Shuk thought.

However, he notices that the portal was set to a different time. A time that made him smirk.

"Well, I may not stop the wedding, but I now have a way to ensure your parents will never marry!" He laughs as the portal opens again.

Lilith saw the portal opening to her parents getting ready to take her out on a walk. But that was no normal walk.

"DON'T YOU DARE!" She shouted, angrily.

Shuk laughs and jumps into the portal. Lilith knew it was wrong to mess with the past, but she couldn't let Shuk do anything to her parents.

"Sorry, Clockwork, but I need to keep my parents safe!" Lilith said, jumping in as well.

Amity Park, Present Day,

Danny was trying to catch his daughter, who was floating around, turning invisible, and laughing. At only three months old, Lilith was really letting her powers out. To think a hybrid would cause so much trouble.

"Did you get her?"

Danny turns and saw Cerberus running up to him. It was a few days after Mince tried to take Cerberus against her will, but Lucifer made short work of him. She not only freed all the demons that he had 'working' under him, but she strips him of his power. Meaning he was no longer a Dealing Demon. Danny heard his daughter laugh and look for her.

"Come on, Lilith. Well, going on a walk today remember?" Danny called out.

"She is hiding again?"

Danny turns and saw Lucifer walk up, wearing normal clothes and carrying a bag over her shoulder.

"Yeah. She's having lots of fun with her newfound ghost powers." Danny sighs.

Lucifer sighs as well. She looks around and then reaches up. She grabs something and pulls it down. Lilith reappears and hugs her mother, giggling.

Danny sighs and steps up.

"Well, I guess it's time," Danny said.

"Indeed. I've asked your mother for a few tips about being a mother, and this walk sounds like a good idea." Lucifer said.

"I guess so," Danny said, tickling his daughter.

"We're so jealous of you, Danny!" Cerberus said, whining.

"And I told you, no one else is having kids until Danny is of age!" Lucifer said, rubbing the bridge of her nose.

"Justice is in charge until we get back. And stay out of Danny's room!" She added.

With that, Danny, Lucifer, and Lilith headed out. Unknowing that a strange portal opens in the sky and Shuk flew out. He spotted them and smirks. He started to follow them, waiting for the moment to strike.

The Park,

Lots of people stared at the 'family' that enter the park as Danny sighs. He was aware everyone in town knew about his relationship with Lucifer and who the baby was. Even a few of his enemies know of them. Lucifer could tell this was getting to Danny, and she was trying her best to be a good girlfriend and mother to her family. She was still used to being the Queen and CEO of Hell. But now she was more than that.

They continue to walk through the park before Lucifer grabs Danny's hand, confusing him.

"Just act normal." She told him.

Danny sighs and nods. They kept walking until they reach the pond. Lilith started to reach out, seeing the ducks in them. Danny smiles and carefully rubs her head.

"Sorry, Lilith. But those aren't rubber duckies." He said, seeing her look at him confused.

Danny then reached behind him and pulls out the toy bear, which Lilith smiles at.

"Grrr! I'm much better than those duckies! I'm going to eat you up!" Danny playfully growls and started 'attacking' Lilith with the bear.

Lucifer smiles as she saw how much of a father Danny was being. To think all this started when Danny was sent to hell against his well. Sure, she had sex with him when they first meet, but she now comes to understand him much better. Suddenly, Danny's ghost senses appear out of his mouth and spotted a red whisp from Lilith's mouth.

Danny stood up and started to look around. He then spotted an ectoblast heading for Lucifer and Lilith and quickly acted.

"LOOK OUT!" He shouted, pushing them out of the way.

Lucifer quickly wraps her arms around Lilith to protect her as her back hits the ground as Danny places his body over both of them. Danny looks up and notices how close he was to Lucifer's face. Both of them blushed before hearing Lilith growling. Danny quickly got off them and looks up to see a ghost he has never seen before.

"Well, well, Danny Fenton and Lucifer Devil. And little baby Lilith. How nice to meet you. Fourteen years into the past." Shuk smirks.

"What?" Danny asked, confused.

"My name is Shuk, and I here on a mission from my Mistress." He said

"What mission?" Lucifer asked, standing up.

Shuk smirks before blasting Danny into the pond, making the ducks fly away. Lucifer growls and raised one of her hands.

"Uh, uh, uh, I wouldn't do that if I were you," Shuk said, holding up Lilith.

"HOW DID YOU?!" Lucifer asked, looking to see if Lilith was still in her arms. She wasn't.

"Call it a little trick of my own, Lucifer," Shuk said, looking at Lilith.

The baby growls and shot a little fireball from her mouth that hits his face. Shuk smirks and laughs.

"Nice try, Lilith. But that fireball doesn't work on me when you're a baby. Speaking of which," He said before seeing Danny float out of the pond in his ghost form.

Danny flew closer and stood ready. He knew this ghost has his daughter, and both he and Lucifer didn't want to risk hurting her.

"What's the matter? I thought the Ghost Boy and the Queen of Hell were better than this?" Shuk laughs.

Both of them didn't move. They were trying to figure out a way to get Lilith away from him in order to take him down. Shuk smirks before feeling someone tapping his shoulder. He turns to see no one there before looking back, only to see that Lilith wasn't in his hand anymore.

"WHAT?!" He shouted.

"How did you do that?" Lucifer asked.

"Huh? I thought that was you." Danny said.

"Unbelieve! I can't believe you!"

Everyone turns and saw a teenage ghost girl holding on to Lilith before floating down.

"YOU!" Shuk said.

"Here's a tip, the next time you decide to jump to the past, make sure to close the door!" She said before punching him away.

Danny and Lucifer stared at the girl, finding her very familiar. Even Lilith looks at her with confusion. The girl turns and walks up to Lucifer. She hands over Lilith, which Lucifer took, and looks over her.

"Who are you?" Danny asked, never seeing a ghost like her.

"That's might be a bit hard to explain." She said before turning to see Shuk standing up.

'Damn it! She had to follow me! Her parents are strong even in this time but with their daughter backing them up. I need to fall back and come up with a new plan.' He thought.

"You got lucky this time! But the Black Misstress will have you, Danny Phantom!" He said, throwing something to the ground.

Smoke cover him and Danny was about to fly into it, only for the girl to stop him.

"Don't! That cloud is full of Blood Blossoms! You won't survive without a cure!" She said.

Danny blinks in surprise and saw the cloud disappear, and the ghost was nowhere in sight. Danny looks around but didn't see him anywhere.

"Who was that guy? And who's the Black Misstress?" Danny asked.

The Girl looks away and rubs her arm. Lucifer could sense something about this girl and stepped up.

"You save our daughter. And you know that ghost. I demand you answer us." She said.

The Girl sighs and saw no one was around. She took a breath and face them.

"My name is Lilith Devil-Fenton. And I'm from the future. I'm your little girl, all grown up." She said, shocking the two.

"WHAT?!" They shouted.

Later, at the apartment,

Danny and Lucifer look at the girl that calms to be their future daughter as the other girls looked at her in shock. Cerberus walks over to her and sniffs her.

"She smells like Danny." The first one said.

"And like Lucifer," The Second added.

"And our noses don't lie." The Third said.

"Amazing!" Azazel said, writing this down in her notepad.

"Are you really Lilith grown-up?" Justice asked, rubbing her chin.

"I know it's strange to believe, but it's the truth. This isn't the first time dad had dealt with time-traveling before." She said.

"Huh?" Danny asked.

"Remember? You first discover about one of your futures where you became evil and destroy the world? Or about the time you went back to the past to stop Vlad from getting his powers, only to make Grandma and Grandpa live different lives?" She said.

"How do you know about that?" Danny asked.

"You told me. When I turn ten. I was interested in your's and mom's past and you told me about time travel and the dangers of missing with past. I know I'm doing lots of things just by being here, but I did it to save you two." Lilith said.

Danny raised an eyebrow as Lucifer set baby Lilith in her playpen. Both of them still had a bit of trouble believing her, but they knew she wasn't lying.

"And who was that ghost?" Danny asked.

"His name is Shuk. There isn't much about him that we know. It was said he was created by someone that wanted to win your heart." Lilith said.

"And who's that?" Lucifer asked.

"I can't tell you who she really is, but she goes by Black Mistress. She use to be human before getting some mysterious powers that gave her the power to control darkness. She has been trying for years to destroy all of my aunts and you, mom." Lilith said.

"Why?" Lucifer asked.

"I'm sorry, but I can't say. The only reason I can tell you what I know is because Clockwork is letting me." Lilith said.

Danny nodded at that. If this girl was indeed his future daughter, then Clockwork had to be involved in this.

"So, what was this Shuk doing here?" Azazel asked.

"He was sent back in time to prevent my parents from meeting. Clockwork told me about the plan, and I rush to stop him. But he was able to set the time to where you two took me to the park for the first time." Lilith said.

Danny and Lucifer looked at each other. An enemy from the future was trying to break them up? Lucifer had already decided she wanted to be with Danny. Danny couldn't believe he was dealing with another future problem.

"Then we need to catch him," Danny said, making everyone look at him.

"I already dealt with the future enough times." He said.

"I know everything about his powers. You'll need my help!" Lilith said, jumping up.

Danny knew she had a point. He knew nothing about this ghost. It was a smart idea to learn all about him from his future daughter.

"Alright. Tell us everything you know, Lilith." Danny said.

Later,

Danny and Lucifer floated in the air. Danny was holding Lucifer in a bride-style and Lucifer was trying very not hard not to blush.

"Do you really believe her?" She asked Danny.

"I know it's hard to believe, but as I said before, I dealt with the future trying to mess with my life enough times. If this Black Mistress is trying to break us up, then she doesn't understand that I've grown to like you and the others for who you are. I'm still trying to get over I won your heart, but I really don't see you as the devil." Danny said.

Lucifer had to smile. He was clearly different than the first time she met him. She reaches up and kisses him. Danny was surprised for a second before returning the kiss.

"You treated me like a normal person. That's what I love about you. And having a daughter together was something not on my list. I mean, I was trying to claim you as mine back when we first met." She said.

"You raped me." Danny deadpanned.

"I did not rape you!" Lucifer groans.

Not far from them, Lilith rolled her eyes at her parents. Even as young adults, they still love each other. She only hope they would go through with their wedding. As much as she wish she could tell them who the Black Mistress was, Clockwork made it clear it wasn't the time to do so. Right now, she needs to catch Shuk and get back to her time.

"Mom, Dad? Are you ready?" She asked.

They both turned, still not used to hearing that.

"Yeah. You got the Fenton Thermos?" Danny asked, seeing his future daughter pull one out.

"You had some made for me and sisters. Well, they're my half-sisters. The point is, you made sure we never live home without them." Lilith said, wanting to keep the rest of her sisters a secret for now.

They chose not to question her and nodded.

"Okay, let's spit-up. Lucifer and I will check downtown. Lilith, you got uptown. If you find anything, use the Fenton Earphones to contact us." Danny said, making his girlfriend and future daughter nod.

Lilith then flew off as Danny turns to Lilith.

"You know. If Lilith grows up to be like her, then I think we did a good job." Danny said.

"She takes after you a lot," Lucifer said, rolling her eyes but smiling.

"That means we avoid that fate we're worried about," Danny said, smiling.

Lucifer smiles as well. Then Danny's ghost sense went off. He turns around and saw Shuk.

"Well, well, looks like I have you two now." He said, smirking.

'So far, so good. Just got to keep this up a little longer.' Danny thought.

"We know why you're here. And we know why the Black Mistress wants us to break up. Our daughter told us everything." Lucifer said.

"Did she? Want to know something that not even she knows?" Shuk smirks, confusing the two.

"While it's true that the Black Mistress told me to deal with you, Lucifer, I have plans of my own. Most of the plans are to get rid of both of you!" He said, firing an ectoblast at them.

Danny quickly dodges the blast and started to fly around, trying to keep Shuk busy. Down below, Lilith watches as her father dodges Shuk's blasts while carrying her mother. She readies herself and pulls out the Fenton Thermos. She knew she had to save her parents, her future was at stake here. She didn't want to grow up parentless. She flew up behind Shuk and ready a first. She turn visible and flew at him.

"Hey! Shuk!" She said, making the ghost turn around.

She punched him in the punch, breaking his nose as well as giving me a black eye.

"Yep, she's my daughter alright," Lucifer said, proudly.

Danny rolled his eyes before using his finger to blast Shuk in the butt.

"OW!"

Lucifer looks at him and Danny just smirks.

"What? I was getting him back for putting our daughter in danger." Danny said, making Lucifer roll her eyes.

Lilith smirks and grabs Shuk.

"You never think your plans through. No wonder you're the dumb muscle!" She said, punching him with the thermos.

Danny was glad his parents updated the thermos to handle all kinds of damage.

"Okay, Lilith, that's enough. He said, making her stop.

"Ah, just one more punch?" Lilith whined.

Danny looks at Lucifer and she smiles at him. Danny smiles back and looks up.

"One more." He said.

Lilith grins and punched him, right in his balls! Danny flinches at that as Shuk's eyes almost bug out of his face. Lilith then opens the thermos, knowing he couldn't get away.

"Give the Black Mistress a message for me. STAY AWAY FROM MY PARENTS!" She said and sucked him in.

Lilith placed the lid on and looks at her parents.

"That's my girl." Danny smiles.

The Ghost Zone,

As much as Lilith wanted to meet her grandparents in this time, she figured she spend enough time in the past. Both of her parents went with her into the Ghost Zone, with Lucifer shocked at how it looked.

But a tour would have to be done later, they soon found Clockwork's Lair and flew in, knowing he was waiting for them. They landed on the floor and Danny set Lucifer down.

"Ah, Daniel! I was expecting you. As well as you, Queen Lucifer." He said, not turning.

Danny and Lilith both rolled their eyes while Lucifer looked confused.

"Mom, meet Clockwork," Lilith said.

"He's the master of time. He knows everyone even if you never met him." Danny added.

"Then you know what I'm here. I hope I didn't do too much damage?" Lilith said.

"Not at all. You save yourself and caught the ghost that was sent back in time. I know the Black Mistress will not be happy that her plan fail. Even if he went to the wrong time." Clockwork said.

Lilith smiles before facing her parents.

"Well, it was great seeing you, Mom and Dad." She said, rubbing her arm.

Danny smiles and pulls his future daughter into a hug. Lucifer smiles and joins in. Lilith hugs both of her parents and had some tears coming from her eyes. They broke, and she wipes them away.

"Hey, keep up the good work," Danny said.

"It doesn't matter if you're a hero. I couldn't be more proud of you." Lucifer said.

"That doesn't explain why you like dad," Lilith said.

"Your father is different," Lucifer said, blushing a bit.

"It's time," Clockwork said, opening a time portal.

Lilith nods and looks at her parents one more time.

"Mom, Dad? And you make sure I grow up as your child?" She asked.

"That's the plan." Danny smiles.

"Just behave and listen to what we say, young lady," Lucifer smirks.

Lilith sticks her tongue out before giggling. She turns and jumps into the portal, heading back to her own time.

Danny placed a hand on Lucifer's shoulder.

"I know we didn't get a chance to spend time with her, but she's already waiting for us back home," Danny said.

Lucifer sighs. She knew he was right.

"If you wish, I can show you your daughter's future." Clockwork said.

Lucifer looks down before shaking her head.

"No, I like to find out myself." She said.

Clockwork nodded. The future was safe.

And done. Yeah, Lilith from the future went back to the past to save her parents. Sorry I didn't give more time with the Fenton-Devil Family. Lilith didn't want to stay in the past for too long and I was getting a little tired of writing this chapter. But at least I covered one of my ideas. So the next chapter will be about Azazel's new friend, and I'll wrap it up with a Halloween chapter. And I wouldn't mind some help! Remember, you guys help me out a lot during this story. And won't mind some help for Azazel's friend.
