Prologue: Blast To The Past.

It was a beautiful day at the city of Amity Park, Minnesota in the year 2043. It's been twenty years since half of the population was brought back to life thanks to the efforts of the legendary superhero group known as the Avengers and the Battle of Earth, one of the largest extraterrestrial conflicts in Earth's history, which led to the defeat of 2014 Thanos after reversing the Decimation and the sacrifice of Tony Stark. It's also been twenty years since Team Phantom had retired from the Avengers after the Battle of Earth. In the past 20 years, the lives of the members of Team Phantom changed forever and still continue to protect Amity Park from world ending ghost threats. As for the legendary Danny and Dani Phantom, their lives change big time and continue to go on with their lives while continuing to lead Team Phantom. Danny eventually got married to his long time best friend and girlfriend Sam Manson. Dani also eventually got married to her long time best friend and boyfriend Jacob Collins, now becoming Danielle Collins. Both Danny and Dani's respective marriage lives is the best they can ask for. Anyway, at a nice blue-painted two-story house, Danny and Sam were starting their day. 49 year old Danny Fenton, who is better known as the famous ghost fighting hero and legendary Avenger Danny Phantom, has grown mature since then. He still maintains his physical built and his blue eyes, but he now has some gray in his black hair. He is wearing a black sweatshirt, a pair of blue jeans and red converse shoes. 49/44 year old Sam Manson, now Sam Fenton, has change in the past 20 years. Ever since becoming one of the victims to Thanos' Decimation and being brought back to life 5 years later, her life definitely change and sees life differently. She also went to love Danny even more, especially after they got married and she gave birth to two children. Sam will always be by Danny side as she promised to him back in 2013 and now will always support both Danny and the kids. Sam still has her figure that would make Danny swoon, purple eyes and long black hair. She is currently wearing a black shirt with the iconic white Team Phantom DP logo, blue jeans and black boots. And because she was one of Thanos' victims, she biologically look 44 years old when she's actually 49 years old chronologically.

"Morning, Sam." Danny greeted as he kissed his wife on the cheek.

"Morning, sweetie." Sam greeted back. "I already made your breakfast."

"Thanks." Danny said before eating his breakfast that Sam made for him. "Well, last day before the kids are on Thanksgiving break."

"That reminds me, I gotta go to the store and get the stuff for the annual Thanksgiving dinner." Sam said.

"As long as dad doesn't do anything to the turkey, it'll be good like last year's." Danny said.

"Definitely. Also might have to double the food due to Mr. Fenton, Dani, DJ and Diana's huge appetites." Sam said.

"Well, let's just hope there won't be any extraterrestrial or ghost threats." Danny said.

Suddenly, someone rang the doorbell. Sam went to open the door to see Dani on the other side of the door. 45 years old biologically but 33 years old chronologically, Danielle Fenton, now known as Danielle Collins and better known as the famous ghost fighting hero and legendary Avenger Dani Phantom, has also grown mature since then, although she maintains her cheerful, fun and tomboyish personality. She still has her figure that would make her husband Jacob swoon, long black hair that flows freely, blue eyes like her brother's, and she is currently wearing a gray sweater with purple trimmings, a black shirt with a blue trimming underneath her sweater, a pair of blue jeans and black boots.

"Oh, morning Dani." Sam greeted.

"Morning, Sam." Dani greeted.

"Come in." Sam said, letting Dani enter the house.

"Morning, big bro." Dani greeted.

"Morning, little sis." Danny greeted.

"Well, I'm gonna go to the store and get the stuff." Sam said as she kisses Danny on the cheek.

"All right, sweetheart." Danny said as Sam leaves to go to the store leaving him and Dani alone.

"So, last day before the kids are on Thanksgiving break." Dani said.

"Yep, then we can have a nice family time, especially on Thanksgiving." Danny said.

"Looking forward to it. Let's hope it's better than last year's since dad didn't do any cooking." Dani said.

"True, the only thing we have to worry about is the food." Danny said.

"Fenton DNA, someone will get a massive appetite, like dad, DJ, Diana and myself." Dani said with a grin.

"Yeah, well, as long as there isn't any extraterrestrial or ghost threats, we'll have a good family Thanksgiving dinner." Danny said.

At that moment, a holographic alarm goes off, indicating a message from the A.I. assistant ZOE. ZOE is a natural language user interface computer system and A.I. program created by the late Tony Stark as a gift for the Fentons right before his death. ZOE is tasked with running business for the Fentons, Collins and Westons, as well as running security for their respective homes and Amity Park. ZOE also helps Team Phantom with their combat operations and is tasked with monitoring the Ghost Zone and detecting potential extraterrestrial and ghost threats at or near Amity Park and in some cases the world itself, like right now as she is trying to contact Danny and Dani.

"And I think I jinxed it." Danny said before tapping on the holographic button. "What do we got, ZOE?"

"Detected large ecto-readings near City Hall. I believe a large natural ghost portal will be formed soon." ZOE replied in a feminine voice.

"Any ghost threats at the Ghost Zone?" Dani asked.

"Detecting something large in the Ghost Zone and believe to be at the point at which the portal will be formed." ZOE replied.

"That's not good." Dani said.

"Should I alert the rest of the team?" ZOE asked.

"Call only Sam and Jacob. Dani and I will investigate and see what we'll be dealing with. If it gets bad, I'll order you to call the rest." Danny said.

"Will do." ZOE said.

"Well, we better go investigate, big bro." Dani said.

"I'm going ghost!" Danny and Dani said, hollering their battle before the two familiar bright rings appear around their waists and traveled up and down, changing them into their ghost forms, with Danny still wearing his famous Fenton glove suit and his white hair now has a streak of black and Dani wearing her collared suit and her white hair becoming a white flame.

Danny and Dani then went intangible before they flew off to go investigate a potential natural ghost portal and threat.

Meanwhile, at the campus of Casper High School, the school day is about to get started for the faculty and students attending there, including two special teenagers. One of them is a teenage boy who had a striking resemblance to Danny. He had black messy hair and fair skin. However, he had purple eyes and he is currently wearing a blue shirt with white letters that spell 'NEW YORK' over a gray long sleeve sweatshirt, a pair of blue jeans and dark red converses. The other is a teenage girl who had a striking resemblance to Sam. She had blue eyes, wearing pink lipstick and starting to show the features of a young woman. She had long black hair that flows freely and the bottom half of her hair had dark purple hair dye. She is currently wearing a dark blue shirt, her midriff exposed, a purple bracelet on her right wrist, black jeans and black boots. The son and daughter of Danny and Sam, 17 year old Daniel James Fenton Junior, or DJ as he likes to be called, and 14 year old Lilith Fenton may consider themselves ordinary teenagers, despite being the son and daughter of Danny and Sam, but they are much more than that. The two has just entered the hallways of Casper High as they head for their lockers to get their belongings and start their last day of school before the Thanksgiving break.

"Well, Lilith, one more day of high school drama and then we're off for a week of relaxation." DJ said.

"And then we can have a nice Thanksgiving dinner. Just hope you, Diana, auntie Dani and grandpa Jack don't hog out all the food again." Lilith said.

"Hey." DJ said.

"Well, besides that, yeah, looking forward to the family dinner. Hope it will be better than last year." Lilith said.

"Same here, Lilith." DJ said.

"Hey, guys!" a girl's voice is heard.

DJ and Lilith turns to see a African-American girl who has long black hair, green eyes and is wearing a long sleeved purple shirt, a black tanktop underneath, blue jeans, black combat boots, two sets of red piercings on both her ears and a gold necklace. It's Lilith's childhood friend Candence Foley, who is the daughter and only child to Team Phantom members and former Avengers Tucker Foley and Valerie Foley, who is known as the Red Huntress and formerly known as Valerie Gray.

"Hey, Candence." Lilith greeted.

"Finally, after today, don't have to worry about school work and now I can focus on beating that new level on Doomed hopefully before Thanksgiving Day." Candence said.

"Oh yeah, we gotta find a way to get pass that." DJ said.

"So, I guess all your relatives will be visiting town?" Candence asked.

"You know how it is every year, Candence." Lilith said.

"Well, hope you all have a great time." Candence said.

"As long as there won't be any ghost threats." DJ said.

Suddenly, the doors open as a random teenage boy burst in the school.

"Hey, everyone! Something is happening outside!" the boy hollered.

At that moment, everyone at the hallway, except DJ, Lilith and Candence, started to head outside to see what the boy is talking about.

"What's going on?" Candence asked.

"Might as well check outside to see what's the commotion about." DJ said.

"I hope it's not bad." Lilith said.

DJ, Lilith and Candence join with the rest of their classmates and went outside to see what's happening. As soon as the three teens went outside, DJ and Lilith eyes went wide as they saw a massive natural ghost portal starting to form.

"Uh, do natural ghost portals form that big?" Candence asked, concerned about the size of the portal.

"No... well Mom and Dad said a portal did form that size, but it was back in 2013." Lilith replied.

"Doesn't matter, I don't like it and I'm pretty sure the team is heading there now." DJ said.

"You two better do your thing." Candence said.

"I'm going ghost!" DJ and Lilith hollered.

At that moment, two familiar bright rings formed around DJ and Lilith's waists before they traveled around their bodies, changing them to their ghost forms and becoming the next generation ghost fighting heroes DJ and Lilith Phantom. DJ skin was now tan and hair is now white but his eyes are blue instead of green like his father. DJ was wearing a green and black hazmat suit. The top part was neon green with a circular black collar and has the iconic white DP symbol at the chest. He was also wearing white gloves with some green detailing, green accents above them and has two vibranium-built Fenton Thermoses attached to them. He also wears a white utility belt, similar to Danny's, and white boots with green accents above them and black pants with green accents that run down to knee length. Lilith also has tan skin, wearing teal lipstick and white hair, but her once purple dye at the bottom half of her hair were now light teal, and her eyes were glowing neon green. Her outfit was a two piece suit, her midriff exposed. Her top was sleeveless and is black with teal trimmings at her collar and bottom of the top and has the iconic DP symbol on her chest. She was also wearing teal gloves with some dark teal detailings and has two vibranium-built Fenton thermoses attached to them. She was also wearing a teal utility belt, similar to Dani's, black pants with teal accents as well as teal detailings that are triangular form and teal shoes. With that, DJ and Lilith start to fly towards the direction of the portal.

Meanwhile, at the campus of Casper Middle School, the school day was also starting for the faculty and students attending there, including one special teen and pre-teen. One of them is a teenage boy who had a striking resemblance to Jacob Collins, but have some differences. He has short military cut black hair, blue eyes and wearing a purple shirt over his white long-sleeved shirt, black jeans and neon green converse shoes. The other is a pre-teen girl who had a striking resemblance to Dani, but also had some differences. She had long messy brown hair that flows freely down, wears pink lipstick, green eyes and wearing a light blue shirt, light purple jeans and light blue converse shoes. Oddly enough, despite being 12 years old, she is also already starting to show the features of a young woman. The son and daughter of Dani and Jacob, 13 year old Robert Collins and 12 year old Diana Collins may also consider themselves ordinary teens or pre-teens, despite being the son and daughter of Dani and Jacob, but they are also much more than that. Two are outside waiting for the first warning bell to ring when a sudden blue mist exit out their mouths as their ghost sense went off. Robert and Diana then noticed fellow students pointing and looking in one direction. Robert and Diana looks at the direction and saw the massive ghost portal forming.

"Oh, this is not gonna be good." Robert said.

"You said it, big bro. You think Mom and Uncle Danny knows about this?" Diana asked.

"Most likely, same for DJ and Lilith." Robert replied.

"We better get over there." Diana said.

"Definitely. They're gonna need our help." Robert said.

"I'm going ghost!" Robert and Diana hollered.

At that moment, two familiar bright rings formed around Robert and Diana's waists before they traveled around their bodies, changing them to their ghost forms and becoming the next generation ghost fighting heroes Robert and Diana Phantom. Robert's skin is now tan, his hair now white and his eyes were glowing neon green. Robert was wearing a dark blue and black hazmat suit. The top part is dark blue in the middle, has a black triangular collar and has the iconic white DP symbol at the chest. He was also wearing white gloves that has dark blue accents on the top and has two vibranium-built Fenton Thermoses attached to them. He also wears a white utility belt that is similar to his uncle's and white boots with dark blue accents above them and black pants. Diana, in ghost form, is the most unique of her family. She also has tan skin, wearing purple lipstick. However, unlike her brother, cousins, mother and uncle, she has blonde hair instead of white, and the only one in which her eyes are red. Her outfit was a two piece suit, her midriff exposed. Her top was sleeveless and is black with purple deltas and a purple triangular collar and has the iconic DP symbol on her chest. She was also wearing purple gloves and has two vibranium-built Fenton thermoses attached to them. She was also wearing a purple utility belt similar to her mother's, black pants with purple accents and becomes purple from above the knees to all the way down and purple shoes. With that, Robert and Diana starts flying towards the direction of the forming ghost portal.

Meanwhile, near City Hall and the forming ghost portal, Danny and Dani has arrived at the scene and the first thing they noticed is panic from the people fleeing.

"It's been 30 years since a portal formed that big." Dani said.

"Well, whatever it is, we're ready to face whatever is gonna come out on the other side of it." Danny said before he activates a device on his Fenton Glove to contact ZOE. "ZOE, contact the rest of the team."

"Will do." ZOE said.

"Let's hope they get here on time." Dani said.

Suddenly, Danny and Dani's ghost sense went off, knowing that a ghost is on the other side of the portal. Suddenly, multiple shadow-like ghosts came out through the portal and landed in front of the two Phantom siblings.

"What the heck are these ghosts?" Dani asked.

"I don't know and I don't care. All I know is that these ghosts have bad intentions." Danny said as he gets into fighting stance.

"Well, let's stop them, big bro." Dani said as she also gets into fighting stance.

The shadow-like ghost forces charge towards Danny and Dani. Danny and Dani immediately started firing ecto-blasts at them. It was a promising start for Danny and Dani as they are destroying the unknown ghosts until one ghost knocks Danny down.

"Danny!" Dani said before another ghost knocked her down.

One ghost was about to blast Danny and Dani until it was blasted back. Danny and Dani look to see Sam who has arrived, and Dani's husband Jacob. 45/40 year old Jacob Collins has also change in the past 20 years. Since becoming one of the victims to Thanos' Decimation and being brought back to life 5 years later, his life also definitely change and sees life differently. He also went to love Dani even more, especially after they got married and has two kids together, who happen to be Robert and Diana. Jacob will do anything to protect his family and will always support his wife and kids. Jacob still has his short military cut brown hair and green eyes. He still wears is Team Phantom attire, wearing a black T-shirt underneath a black vest with pockets, a black belt, black jeans, black gloves and black boots. His upper left pocket on his vest had a white DP logo on it. And because he was also one of Thanos' victims, he biologically look 40 years old when he's actually 45 years old chronologically. Danny and Dani immediately gets up to meet up with their respective spouses.

"You okay, honey?" Jacob asked.

"I'm okay, Jacob." Dani said.

"Thanks for the save, Sam." Danny said.

"Anytime, Danny." Sam said.

"Where's the others?" Danny asked.

"They're on there way still." Sam said.

"Looks like it's just the four of us then." Jacob said as he aims his Fenton railgun.

Danny, Dani, Sam and Jacob charge towards the shadowy ghosts. Sam fires her ecto-blasters at the ghosts as much as she can while Jacob carefully fire his Fenton Railgun at the ghosts, destroying them in a instant. He also fire on some ghosts that tried to get away from them to try and attack other parts of Amity Park. Danny and Dani once again work together as they have always done since they were teammates and Avengers. They gave everything they got, they use their original, Asgardian, ice and fire powers against these unknown ghosts. Danny then blast one ghost that was about to strike Sam while Dani blast another that was about to strike Danny himself. The favor was starting to turn in favor of Danny, Dani, Sam and Jacob until one of the ghosts sends a powerful blast to Danny, causing him to crash into the others. Four ghosts then were about to deal the finishing blow until they were suddenly blasted by four ecto-rays. Danny, Dani, Sam and Jacob look to see DJ, Lilith, Robert and Diana, ready to fight.

"Kids, what are you all doing here? You're suppose to be at school." Danny asked.

"Come on, Dad. You know that at a ghost threat like this, you're gonna need our help." Lilith said.

"Not to mention we're a team. We work together." DJ said.

"And family, Uncle Danny." Diana said.

"Okay, okay. But be careful. We don't know who these ghosts are." Danny said.

Danny, Dani, Sam, Jacob, DJ, Lilith, Robert and Diana then charge at the ghost again and started to go well. Robert and Diana fight with their mother while DJ and Lilith fight with their father. After several minutes, the shadowy ghosts were almost destroyed. Suddenly, Danny, Dani, DJ, Lilith, Robert and Diana's ghost sense went off.

"We got more company." Danny said.

Suddenly, Diana notice a ghost flying very close to the ground and approaching at high speed. The ghost had teal skin, a good muscle built, dark blue eyes, short black hair and a beard. The ghost was also wearing odd Asgardian-like protective armor including a red chestplate, black pants, red boots, and other armor plating around his arms. Diana immediately recognized him.

"It's Gandr! Heads up!" Diana warned.

Dani and Robert noticed Gandr. Dani and her kids then fire a combine ecto-blast together but it had no affect. The ghost known as Gandr was flying close to the ground and summoned his unique ecto-shield power before giving a powerful ecto-energy strike to Dani, Robert and Diana, which ended up knocking Dani unconscious and made Robert and Diana crash to the ground. Gandr then flew into the air, evading the multiple ecto-rays being fired towards him. Gandr then flew near the ground once again and started flying towards Danny, DJ and Lilith. Danny, DJ and Lilith worked together to fire a combined ecto-energy blast at Gandr. However, Gandr summoned his unique ecto-shield power again, protecting his whole body, and overwhelmed the combined ecto-beam. Danny, DJ and Lilith couldn't stop Gandr from giving them a powerful ecto-energy strike, also knocking Danny unconscious and made DJ and Lilith crash to the ground. Gandr then blast Sam and Jacob down to the ground before they can react. DJ, Lilith, Robert and Diana got back to see Gandr, who they have faced before.

"Gandr. What are you doing here?!" Robert asked.

"Yeah, didn't we beat you countless times? Thought you learn your lesson by now." Lilith said.

"Always arrogant, huh, little Phantoms. You little brats are just lucky and you'll eventually meet your fate someday." Gandr said.

"What do you want this time?" DJ asked.

"The same, destroy your world. I was hoping my shadow ghosts would take care of you all, but since you took them all and I'm getting tired of you kids getting in my way, I think it's time I take a drastic measure, one where your future, or should I say, your existence is now hanging in the balance." Gandr said.

Gandr immediately flew towards the portal.

"He's getting away!" Diana said.

"Get him!" Lilith said.

DJ, Lilith, Robert and Diana flew after Gandr, ending up following him through the portal and into the Ghost Zone, while also disregarding their parent's orders of not allowing to be in the Ghost Zone at all.

"What the heck is Gandr doing?!" Lilith asked.

"I don't know, but I also don't like what he said about our existence." DJ said.

"What did he mean by that?" Diana asked.

"Doesn't matter. I see Clockwork's Tower up ahead." Robert said as he sees Clockwork's lair.

"Don't lose him!" Diana said.

"Don't worry, cuz. We won't!" Lilith said.

The four kids continue to chase Gandr, but he is way to ahead of them.

"Gandr's too darn fast!" DJ said.

"You're telling us that?!" Lilith asked in annoyance.

"He's getting dangerously close!" Robert said.

Gandr then look to see the four teens. He then fired multiple and powerful Asgardian energy flash ecto-beams at them. DJ, Lilith, Robert and Diana managed to evade them all. However, this manage Gandr to fly further away from them. DJ, Lilith, Robert and Diana continue their pursuit, trying to get close to Gandr and stop him.

"We can't let him get away!" Lilith said.

"Why would he want to head towards Clockwork's lair?!" Robert asked.

"Don't know big bro, but we need to stop him!" Diana said.

"I think I know why and what Gandr meant. He's planning to travel back in time to kill our respective parents to ensure we don't exist!" DJ said.

"If that's the case, we gotta stop him and now!" Robert said.

Gandr eventually reached Clockwork's lair, followed by DJ, Lilith, Robert and Diana. Gandr then flew through a time monitor that sends him to the year 2023. DJ, Lilith, Robert and Diana, without any regard, then flew through the same time monitor, also sending them 20 years to the past.

And that's the end of this chapter. Well what do you think of DJ, Lilith, Robert and Diana? I hope you all enjoy this story as this one will be awesome. Well, unlike Endgame, this is indeed a original work, so you have to give me time on the next update, so please don't ask when's the next update because I don't have an answer to this question. Well, what has Dani and Danny been up to since retiring from the Avengers. Stay tune for the first chapter to find out. Please review. :)
