Buffy is Gabriel's daughter
Chuck watched as his granddaughter meet and hit the re-souled Angelus, a 256 year old demonic vampire and he was concerned with the First Evil rising. He frowned thinking of them, he knew he couldn't let it happen so Chuck closed his eyes and looked for his sons, he saw Gabriel with the Pagan gods with Lucifer heading that way, Michael was up in heaven with Raphael and he opened his eyes before sending up four force shields to hold his sons before he clicked his fingers turning invisible as they appeared.
"What? Where" Chuck smirked seeing that Michael was in John Winchester's younger self "Lucifer" Michael hissed spotting his next youngest brother, who had skin peeling on his face while wearing a simple cargo jacket, faded yellow shirt and jeans, his vessel had blonde hair and blue eyes.
"Michael, you did this you want to fight now" Lucifer asked with a smirk and cold eyes, taking in his older brother's white shirt and jeans.
"Enough!" Raphael was glaring at the barriers holding them in different places "Force Fields?" Raphael stated and the two older brothers looked to Raphael taking in jeans and a white jacket, his vessel was African American with dark brown hair and light hazel eyes.
"Ouch" the three eldest looked to see to their shock their youngest brother Gabriel holding his hand.
"Gabby?" they asked in shock at seeing the youngest Arch-Angel standing there wearing a cargo jacket, dark maroon shirt and black jeans, while his amber brown eyes were harder than ever while his vessel had dark blonde hair.
"Yeah, yeah" Gabriel glaring at the shield and clicking his fingers before frowning "Bugger, which of you did this?" he asked pointing at each of his brothers who were still in shock.
"I thought you were dead, no one knew where you were" Michael cried out and Chuck saw the others were worried and relieved at seeing the runaway Arch-Angel.
"Look, I hated seeing you all rip at each other throats and then father left and I had to go" Gabriel explained and Chuck sighed running his hand over his face.
"We looked for you Gabby everywhere and then Michael cast me into the cage and till today I feared you were dead" Lucifer said softly, Chuck smiled knowing that Lucifer and Gabriel had a good brother relationship and Gabriel sighed.
"Look, we are flawed, father's creations are as well, no one is perfect and if only you understood that Lucifer" Gabriel said and looked around the room so Chuck decided to reveal himself well only his voice.
"Well said my messenger" that cause Gabriel to smile as his sons looked around shocked "I am sorry you couldn't take the fighting, you were always peaceful and always wanting to play pranks or joke around yet you always had a serious side" Chuck smiled seeing his youngest Arch-angel smile.
"Father, where are you?" Raphael asked looking around the room.
"Here in the room, just out of sight for a bit till I know you all have settled down at seeing each other" Michael and Lucifer looked at each and their father continued "my healer like Gabriel you liked it when you all got along, till Michael and Lucifer fighting got worst and dragged you in, I saw it son and while I am disappointed in you all I am happy to see you here for there is something more important than Michael and Lucifer apocalypse to bring hell or paradise to my world" Chuck stated and his sons frowned.
"I thought you wanted Lucifer and I to battle, father" Michael said in uneasy tone of voice while Lucifer was looking at Michael.
"At first I wanted you both to resolve it and not drag your brothers into it" Lucifer and Michael blushed, while Raphael shook his head at his older brothers and Gabriel was looking for his father's voice "I left and hid here on Earth and for centuries watched over humans fight over small things or large, I was happy how my life was going... well as happy with one son in the cage, one son becoming cold and uncaring, one son had runaway and hiding on Earth as well" Chuck sighed "21 years ago I had a vision of two things coming to destroy Earth that would do greater damage to my creations than Lucifer and Michael's fight and well I have been watching and one entity has waited for 99 years and with only 31 days to go before the world is covered in darkness with the threat of unlocking your aunt" Chuck explained causing gasps and he saw Lucifer looking at Michael.
"Who could release the Darkness?" Raphael asked and Chuck turned visible again causing Michael and Raphael to be shocked.
"Father, you disguised yourself as a prophet" Chuck smirked and Gabriel laughed loving the fact their father was in plain sight and none of them sensed it "Never knew you could pull a prank over like that well done father" Gabriel said with a clap of his hands while Raphael and Michael glared at the youngest while Lucifer was laughing at seeing the joy in Gabriel's eyes and laugh.
"Thank you, Gabriel, now before anything the vision had a young girl destined to be the Slayer" Chuck clicked his fingers sensing Buffy fighting tied to a large stake and he clicked his fingers as a TV appeared.
The screen showed a blonde haired young woman tied to a large stake looking at a demon, but not from hell the Arch-angels knew before she bent over and the stake went through the neck of the creature.
"Did I get it? Did I get it?" she said looking around and then two young men fell from the ceiling and looking up in shock.
"We're here to save you" the ginger red said in a confused voice and Chuck clicked his fingers and the TV disappeared and Chuck looked at his eldest sons.
"The young woman is named Elizabeth 'Buffy' Anne Summers, well she is not the normal slayer or fully human" Chuck looked to Gabriel who was shocked causing his brothers to look at each other.
"Dad, I swear I thought she was dead" Gabriel stated shocked and scared while the eldest brothers looked at the youngest worried about seeing the distress look in Gabriel's amber brown eyes that was flashing gold.
"I know son, I am not angry for her existing, for she had always had destiny and still does" Chuck smiled softly at Gabriel who was in shocked before looking at his eldest sons "Michael, Lucifer, Raphael" the brothers had a feeling they knew what Gabriel had done "Gabriel fell in love with a mortal named Joyce Summers, Buffy is the result and before Gabriel left to give just deserts once again locked Buffy's grace away and once she was on the Mouth of Hell well one of them, your aunt Amara created those, anyway once Buffy arrived at the the Mouth of Hell" Chuck looked down before looking up to his sons "I decided to create a barrier to keep angels and other demons that did not belong out Sunnydale to protect Buffy till she was ready and trained to face the angels and the demons out here" Chuck smiled "she has a destiny there, but now that destiny is threaten by a sorcerer who will turn into a pure Earth based demon one not from hell but a different dimension" Gabriel fell to his knees and Chuck walked over and bent down to him releasing the force field containing Gabriel.
"I mourned her and Joyce, dad" Gabriel whispered and Chuck sighed running a hand through his youngest son's hair.
"I know" Chuck looked at the eldest three "I need you four to go and help, I will not go for if Chuck Shurley disappears from Castiel's sight then Heaven will be alerted and start looking for me rather intensely, you four need to work together and bring Richard Wilkins down before the eclipse starts and unlock Buffy's grace train her to use it and no fighting with each other" Chuck said and Raphael bowed his head.
"I promise father to keep Michael and Lucifer in line, however with Lucifer's vessel and Samuel Winchester saying no how is Lucifer to walk around with how he looks" Raphael asked and the two brothers in question sighed before nodding to each other.
"We agree not to fight" Lucifer stated calmly and Chuck smiled.
"How bad would this Wilkins be?" Michael asked and Chuck sighed shaking his head.
"He will bring pure breed demons straight from the Hell-Mouth before taking over the world, not even the demons that possess humans would live as well as unlock Amara's cage" Chuck sighed and walked over to his chair as his sons watched "Richard Wilkins will find out about me and kill me before destroying the angels in heaven, Lucifer and Michael would be trapped in the cage and Raphael and Gabriel are killed" Chuck said sadly and Gabriel looked up in shock "I will keep watch over you four, if it becomes to dangerous or your lives are in danger I will come but I trust you to train young Buffy" Chuck stated and they nodded "Also as for your vessel Lucifer" Chuck clicked his fingers and the wounds healed up "Nick has moved on".
"Father what is Buffy doing now?" Gabriel asked and Chuck laughed.
"She is currently sleeping, now I have purchased a house with four bedrooms, a basement for training and a few extra things" Chuck explained and the brothers smiled "I will take you to the barrier protecting Sunnydale to let you four in, call for me if you need anything" the brothers nodded and soon they appeared with the help Gabriel and Chuck hid them under a shield at the barrier will there was a layer of power and Chuck opened it.
"Dad, we will keep the world safe from his sorcerer, count on it" Gabriel said with a smirk and Chuck nodded and disappeared.
"Gabe, I am sorry I tried to drag on though the battle between Lucifer and I" Michael said softly as the four walked towards the town.
"It is fine, look I forgive you all, but I need to gather my thoughts" the brothers saw Gabriel looking towards the town "Joyce, father never said if she were alive or dead" Raphael rubbed Gabriel's left shoulder "Buffy is a Nephilim, along with being the Slayer and a school girl" Michael smirked.
"Who would be dating soon?" Gabriel jumped and turned to Michael.
"My daughter will not be dating" Gabriel stated with a cross of his arms making his brothers laughed and he frowned.
"You will be fine, Gabe" Lucifer said softly and soon they arrived at the house their father brought and entered.
"Nice" Gabriel said with a smirk seeing the giant TV and jumped over the couch turning on a film, his brothers shook their heads. Lucifer grabbed Gabriel who groaned and walked with them. They saw an small infirmary where Raphael smiled and whispered to his father thanks. They found a kitchen with a note saying it was time for them to learn to cook for Buffy and her friends.
"Bugger" Lucifer said and Gabriel smirked.
"I already can cook, well summon food and the Winchesters liked it fine" the three brothers glared before the decided to find their rooms.
They found each room had a large TV and bed, even though none of them slept but they were there for relaxing and each room had enough place to stretch their wings out without fear of showing their true form seeing as their father made the bodies theirs well in Gabriel's case he already had the soul of his vessel pass on.
As morning broke, Gabriel decided to find where his daughter's school was while his older brothers played around with the TV, as the three of them had not been around TVs before and Gabriel decided to leave a small prank in the kitchen and left the home.
