When the girls made it downstairs, everyone was shocked to see Jazz in a demon form. Jazz quickly explained that she became a demon of her own choice and Lucifer told them that she made sure that was what Jazz wanted. Jazz now carried a piece of her power, meaning Lucifer lost some of her return power.

"Wow, Aunt Jazz, you look nice," Lilith said, looking at her adopted aunt.

"Thanks, Lilith. I don't know how much power I truly have, but I will do my best to help you find Lucifer's power and stop any demon from escaping Hell." Jazz said.

"Well, I know one thing. We need to train your demon form." Danny said, sighing.

"And before anyone asks, I'm not giving up any more of my power. I need what I have left to find the others and get Sam's piece." Lucifer said, wanting to make one thing clear.

Jack and Maddie sighed. To think their kids had become demons. Though, not in the way most people would think.

"Jazz, why did you want to turn into a demon?" Maddie asked her demon daughter.

"I was envious of Danny and Lilith. Seeing them in their demon forms made me wonder what it would be like if I were also a demon. The reason I didn't confront them about it was because I didn't want to come off as a bother to everyone. Lucifer surprised me by offering a piece of her power because I returned her name." Jazz said.

"I even warned her that it would hurt. Jazz received her piece differently from everyone else. Most of them agreed to a deal. Danny was already dead when I gave him one of my leftover pieces." Lucifer explains.

"Well, I guess we might as well head down to the lab and start training," Danny said, making everyone nod.

Lab,

Danny and Lilith stood in their demon forms, facing Jazz.

"Are you sure about this, Jazz? Lilith and I had our powers longer than you, you know." Danny asked her.

"I know. But it might give me a good idea of how I can stand between the two of you." Jazz said, pushing her glasses up.

"Quick question, why are you wearing glasses when you don't wear any in your human form?" Lilith asked.

"No idea, yet. For now, I'm keeping them." Jazz said, shrugging.

Danny nods, ready himself as Lilith does the same. Jazz felt herself read the two before a plan formed in her mind. Danny rushed forward, getting ready to throw a punch. However, he sidesteps to show Lilith coming at her with an axe kick. However, Jazz blocked it before she pushed Lilith off and threw up her leg to block Danny's. The siblings face each other before trading blows. Punch meets punch. Kick meets kick. They even headbutted each other, causing them to both jump back as they grabbed it.

"Okay, that was a bad idea," Danny said, holding his forehead.

"Tell me about it. I'm glad our horns didn't get caught up." Jazz agreed, rubbing hers.

"Shouldn't our horns have some other use, besides telling how old we are?" Lilith asked, turning to Lucifer.

"There are some demons that have tried to use their horns much like a bull, but most don't even bother, myself being one of them," Lucifer said, shrugging.

Lilith sighs before facing her aunt again. Jazz notices and quickly reads Lilith. Lilith ran forward, jumping up like she trying to axe kick her again, only to instead dive at her with both feet. Jazz crosses her arms in front of her and blocks the double kick. Before Lilith could move, Jazz grabbed her niece's feet and threw her into Danny.

Lucifer starts to think to herself, getting a read on Jazz's demon power. It was small but she could see enough of what was going on.

'Interesting, it looks as if Jazz knows what they are about to do before they even do it. And she even plans ahead to block and counter Danny and Lilith. Danny is the power, Lilith is the speed, and Jazz must be the defense.' Lucifer thought, seeing how all three of them fought.

Suddenly the alarm went off, and the Fenton portal started glowing.

"DAD! I THOUGHT WE TOLD YOU TO UPGRADE THE PORTAL!?" Danny shouted.

"I was going to!" Jack started before the portal was ripped open.

"LUCIFER!"

"FUCK!" She screams, knowing that voice.

A huge demon started to push itself through the portal somehow only getting its right arm out.

"What is that?!" Maddie shouted.

"Someone that you two DON'T want to be around!" Lucifer shouted, standing with the others.

"LUCIFER!"

"Danny, Lilith, Jazz, don't hold back! We can't let that thing through!" Lucifer told them.

"There's a story behind this, isn't there?" Danny asked.

"Later!" Lucifer said, standing ready.

The Huge demon roars, still trying to get out of the portal. It then tried to smash the four with its free arm. Luckily, the floors held up pretty well.

"I told you refining the floors of the lab was a good idea!" Jack brags, smiling.

"MOM! DAD! GET OUT OF HERE!" Danny and Jazz shouted.

The two older Fentons did what their kids asked them to, knowing they might have a lot to fix when this was over. The Morningstar family faces down the huge demon, Jazz quickly reading it.

"Okay, this thing is huge, but it doesn't look that fast. Still, not all demons as they appear." She said, looking at Lucifer.

"True. I imprisoned this demon centuries ago. Unlike the other demon that betrayed me, this was because it was too dangerous, even for me! How in the Hell's name did it get free?!" Lucifer shouted.

The demon roars trying to smash them again.

"The lab might not be able to take much more. Dad's idea of refining the floor is working, even if this wasn't what he was planning for, but I don't know if would hold up." Danny said.

"And it could end up destroying our home if we don't stop it!" Lilith said, not wanting to go back to the orphanage.

That made Lucifer think. If there were so many demons running free, then she needed to go home at some point to ensure that no other demon was trying to take over her throne. Plus, if Fenton Works ended up getting destroyed...

'I'll make plans for that later. Right now, we need to stop this thing!' She thought.

"Jasmine! I know about your ability to read a person's movements. Study this thing as much as you can!" Lucifer shouted.

"Danny, Lilith, the three of us will take this thing head-on. Just don't let it build up fire in its mouth!" She added.

Everyone nodded as Jazz took a step back, trying to read as much as the demon as she could. Danny, Lucifer, and Lilith all jump towards the giant demon. landing powerful blows on its face.

It roars, trying to grab the three. Luckily they all jumped out of the way, causing it to miss. Danny stood next to Lucifer, placing a hand on her shoulder. Lilith ran up and did the same. Lucifer felt herself grow strong and formed a fireball. She fired and it exploded on the demon.

"Wait!" Jazz shouted, recalling where they were.

"How is the lab not getting destroyed?!" She asked, making everyone, even the giant demon, look at her.

"Before I have you my piece, I place a barrier around your parent's lab. So even if the lab gets destroyed, it would be fixed before they even know what happened. Can't say too much about their notes." Lucifer said before facing the giant demon again.

It roars before trying to smash them again. With one arm sticking, and the three keeping it from forming fire in its mouth, it was losing battle for it. Suddenly, Jazz picked up on what it was about to do and ran towards it. She jumped to the ceiling, kicked off it, before bringing her foot down on top of its head. An explosion appeared in its mouth, causing the demon's head to flinch back.

"Son of a bitch! It was building up its fire during the fight!" Lucifer shouted.

"Lucifer, we can keep fighting in here. We need to force it back into hell!" Jazz said, making her nod in agreement.

"Agreed! I need all three of you to touch me." Lucifer said, making them nod.

Danny and Lilith touched each of her shoulders as Jazz touched her back. Lucifer felt the powers from them add to her own remaining powers and felt another power she was missing. Roaring, she threw up her hands and shot a huge fireball at the demon. It roars as the fireball starts to force it back through the portal. Lucifer fired another one, forcing it farther and farther into the portal.

Finally, the last one forced the demon back inside the portal, making Lucifer sigh in relief.

"Well, that takes care of that..." Lilith started before the demon hand reached back through the portal and snatched all four of them, pulling them inside the portal as well.

And stopping here. So, I covered a bit of Jazz's time as a Demon and also made Lucifer tell everyone that she's not giving up any more of her powers, so that means Jack and Maddie will not become demons. So, don't ask.

A bit of training, explain a bit what Jazz can do as a demon. She's more of a planner and defense player, but she's no slouch when it comes to fighting. And it seems that another demon from Lucifer's past is after all. And just to make this clear, NO, Beelzebub is not going to appear in this story! Just because I mention different demons from the portal, doesn't mean Beelzebub will appear. Beelzebub is already imprisoned in the Abyss, and there's no way out once you're in.

However, it seems that the next chapter will cover Lucifer returning to her home, along with her new family. Though, they still have to deal with the Giant Demon first.

And before I forget, Lilith's new form isn't going to be called "The Mommy Demon". That was the name used on the image. I don't have a title for Lilith's demon form, but that image is what she's going to look like later.

I'm giving the same treatment to Danny, and later, Jazz. Danny will remove his black jacket, wearing only the red shirt underneath. His arms will have demonic language on them, each one translating to "Lucifer's King", "King of Hell", and "Daniel, the Hell King."

Jazz will remove her glasses, and let her hair out. She would also trade her long skirt and stockings for a pair of jeans and short heels shoes.
