Lucifer Thornton

Lucifer Thornton (born Zukoni) is a half blood Saiyan, born on Earth-579V, who was raised on Planet Vegeta until the age of 1, when he was sent back to his Earth in an attack ball. He was raised on this Earth, as a human, assuming his tail was normal. When Lucifer was 4, his mum died, due to a mysterious creature in the woods. At age 6, Lucifer's step-dad was killed in the Human-Covenant war, by a Zealot Class Elite. Out of curiosity, and secretly to try and beat his girlfriend, Nobara Kugisaki, Lucifer got his midichlorians tested and came out with 3978. 
=== Childhood ===
Lucifer was born on Earth-579V, May 29th, 2002 (Earth-579V Calendar), in England. Two weeks after he was born, his father, Garl, decided he needed to go back to Planet Vegeta, and would be taking Lucifer with him. Realizing there was nothing she could do, Lucifer's mum, Lara Thornton, let her son be taken away. At the age of 1, Thornton's father knew Frieza, the tyrannical ruler, was up to something, and thought it would be best to leave Planet Vegeta. Garl got into his ship and flew away, but realized he was low on fuel. After days of pondering, he decided it would be best to give Lucifer a chance, and sent him away in an Attack Ball with a course set for Earth. More specifically, England. Upon landing in England, a old man named William found him, and decided to take him in. He took the then named Zukoni to his family home, where his daughter awaited. As he walked through the door, his daughter, Lara, noticed this wasn't a random child. This was her son. She then renamed him, giving him the name she always wanted to call him. Lucifer. 
At the age of 4, Lara was murdered by something in the woods. This infuriated Lucifer, and from that day on, he swore to find who killed her, and destroy them. He began to learn martial arts, and his grandfather taught him Hamon. William had learnt hamon from his best friend, Jonathan Joestar. Lucifer wanted to find his mother's body, and went into the forest to look for it. Dragging a tent behind him, he snuck out into the forest. He didn't need the days he anticipated. 5 minutes into the walk, Lucifer found his mum's body, with burn marks all over her, and two burning holes through her chest. He screamed, but decided he was brave, and tried to drag Lara's body back to the house. Luckily, his grandad heard the screams and ran out to help him. William, looking at his daughters burnt corpse, knew exactly what had killed her. It was a covenant energy sword. He decided it would be best for Lucifer not to know this, and so didnt inform him.
At the age of 6, Lucifer's step-dad, David Thornton, a Gunnery Sergeant in the UNSC Marine Corps, was killed my a Jackal's Beam Rifle to his skull. This not only infuriated Lucifer again, it reminded him of the death of his mother. The moment he found out about his step-father's death, he was set on being the best ODST to ever live. He began physical training, as well as his continuing martial arts. He became stronger than all of his class mates, and became considerably fast. By the age of 10, he could do the 100m sprint in 8 seconds. He was ready to be an Orbital Drop Shock Trooper.
Sadly for him, he couldn't join the UNSC until he finished primary school, and so began to train harder and harder to be at an advantage when he joined their ranks. On the last day of primary school, he was walking home with his friend, who was a girl, when a man started to touch her. Knowing this wasn't acceptable, he tried to stop the man, but nothing would work. Using a last resort, he punched the man in the face, sending him flying across the street. The man's jaw was broken, but he got up and ran at Thornton like it was nothing. Running at him, the man jumped and scratched the left side of Lucifer's face, causing him to bleed immensely. Lucifer realized this wasn't a normal human, and decided it was time to put William's training to use. He channelled all his Hamon energy to his right hand, and punched the man in the jaw. His head immediately popped off and his body flew across the street. He then began to disintegrate. This wasn't a human. This was a vampire
=== United Nations Space Command ===
After his fight with the vampire, Lucifer went home. The morning after he went straight to the enlistment centre and signed up to be an ODST. The examiner noticed his physical, mental and strategic potential, and told him he was in. Lucifer was now an Orbital Drop Shock Trooper. He had a week to prepare. Lucifer ran home to his granddad to tell him the good news, but as Thornton told him, he only looked disappointed. Thinking this was the right time, William explained to Lucifer that Lara's death was the result of The Covenant. He then explained that he'd known since the second he'd saw her body, and explained everyone else he had loved had died because of The Covenant and he didn't want to lose the last thing he had. Lucifer apologized thoroughly, but explained his mind was set, and he would be leaving. Knowing how stubborn Lucifer was, his granddad congratulated him and told him to grab his things.
The week passed unbelievably fast for Lucifer. He and his granddad walked up the stairs to the UNSC facility where Lucifer assumed he would be training. His granddad was not permitted to enter, and so gave Lucifer one last hug, and watched as Lucifer walked to his inevitable death. On the other side of things, Lucifer walked through the facility with a childish grin on his face, two blank-faced marines following closely behind. He had been waiting for this day for 6 years. This was the happiest and proudest moment of his life. As he looked around the facility at the countless marines and ODST's, they all stared back at him, giving him welcoming smiles and nods. There was even a spartan, and he too nodded. Lucifer had heard tales of the spartan's, but had never actually seen one. He was a 7'2 giant of a man. He walked over to them, and the marines saluted. Lucifer explained he was new and the spartan stuck out his hand and welcomed him. Lucifer shook the hand the size of a dinner plate, and thanked the spartan who identified himself as Cash-304. He explained he would be with him from here and walked him to the hangar. When 304 got onto a pelican, Lucifer looked at him confused. Lucifer explained he thought we would be training here. Cash answered explaining he would actually be training on the spartan's home planet. Reach.
Lucifer had never been to space, but had heard the legends about Reach. Ready and raring to go, he strapped into the co-pilot seat and urged 304 to take a seat next to him. The spartan declined, telling him that they could not leave yet as they needed to wait for more new recruits, and that even if they could leave, Lucifer would not be flying. Lucifer sat down in the back, still excited, and asked the spartan to take a seat next to him. Cash explained he would have to greet them, but if Lucifer could save a spot, he would love to take it. Lucifer had only ever seen people describe spartan's as inhuman, acting more like robots designed to kill that actual flesh and bone, with no feelings and no mercy. That was all well and good for a fight, but they must have been insufferable to be around. This one was different. Even if he didn't, he acted like he cared. He was kind. He was funny. He was a spartan. That was all Lucifer needed to hear. After about 10 minutes, 7 more candidates had shown up, and Lucifer still had the seat saved. 304 sat down and they began to chat, and another one of the rookies joined in. This rookie explained he had gained the nickname Phantom. He didn't remember why. Phantom was used so much that he actually forgot his real name. This group of 8 would all pass training, and form together to become Bravo-4 ODST Squad. Lucifer passed with flying colours, outdoing the rest, and so was designated the commander of the squad.
Bravo-4 were deployed on many crucial missions during the Human-Covenant War, such as the Battle for New Mombasa, as seen in Halo 3: ODST, just from a different perspective, and having no interaction with the Superintendent, The Battle on Alpha Halo, or Installation 04, as seen in Halo: Combat Evolved, and sometimes working with The Master Chief, and the Battle on The Ark, as seen in Halo 3, again, sometimes working with The Master Chief. Whereabouts of 304 are unknown for this time period. These events all took place in a time span of about 3 months. Bravo-4 would go on countless missions, over Thornton's 4 years as an ODST, proving to be very efficient, very deadly, and a very valuable asset to the UNSC. All of this would change after Bravo-4 returned from being on a patrol. They had done their duty. They could go home for a while. Lucifer chose to go back home to his granddad. A choice that would change everything.
=== Jujutsu Tech ===
On Lucifer's journey home, he would walk past a hospital where countless had died. In this vicinity, was a grade 2 curse. This curse ran out in front of Lucifer, thinking he couldn't see it. However, Thornton could and hit the curse with Soul Piercing Cacophony, the cursed technique he would eventually master. This exercised the curse immediately. The two sorcerers sent to deal with this curse noted his immense power, and reported back to their higher ups, one being from Kyoto and one being from Tokyo commenting that "An Englishman with no prior knowledge of curses, or cursed techniques, exercised a Grade 2 curse using a cursed technique, with power that with correct training, could match that of Yuta Okkotsu". This caused the higher ups to discuss that matter, and come to a conclusion. Thornton was too dangerous to be left alive, and his execution was ordered immediately. 
They decided to send Gojo after him, and after knocking Lucifer unconscious, brought him back to Tokyo, where he explains what has happened, and why he should be getting killed, and also why he isn't. The higher ups decided Lucifer was too strong for never being taught about curses, and would become a threat. Gojo, however, saw this as a massive waste of potential, and enrolled him into the College. Lucifer had no objections to this, and at the age of 15 and 8 months, he was now a first year at the Tokyo Metropolitan Curse Technical College. He would be joined by Megumi Fushiguro, Yuji Itadori and Nobara Kugisaki. 4 months of training and missions pass, and Lucifer can hold his own against Grade 1 curses, having learnt 2 cursed techniques, and already possessing immense speed. After these 4 months, there is an incident in Shibuya, but the first years took less part in this as they were relatively new, patrolling the border of the veil. Most of the events play out the same as in Jujutsu Kaisen Season 2.
2 months have passed since the Shibuya Incident, and the UNSC and Jujutsu Society have joined forces, realizing bullets don't kill curses, and cursed energy is too short range to kill covenant soldiers, most of the time. As a result of the fusion, a new fireteam is born, Fireteam Zero. In response to this fusion, The Covenant accept curses into their ranks.
=== Fireteam Zero ===
Fireteam Zero was originally made up of Megumi Fushiguro, 0-01, Yuji Itadori, 0-02, Nobara Kugisaki, 0-03, Lucifer Thornton, 0-04 and their mentor who travelled with them, acting as a commander, being Satoru Gojo. They would carry out many missions, being very efficient at exercising curses, and Lucifer's ODST skillset coming in handy many times, to kill Covenant forces. On the way to distress call on the outskirts of Reach, their pelican needed to refuel, and so made a stop on Earth-089A. They encounter a curse like creature, and after many attempts to exercise it, almost leading to Gojo coming and helping, they came to the conclusion, that this was no curse. Lucifer notices a figure moving in the tree line, darting around from bush to bush, tree to tree. Then, suddenly, almost like a flash, a silhouette came flying out, the curses head flying off. The Fireteam were ready to kill the figure, but as he turned around, he sheathed his sword, and so the fireteam calmed down. As he turned around, a tiny girl showed her head from behind his back; After walking over to the pelican, and inspecting it, Lucifer walked over and greeted the mysterious people. The boy turned around and informed them of who they were. Leo and Nezuko Teich. After asking Leo how he managed to exercise the curse, Leo explains that it wasnt actually a curse. It was a demon. Lucifer, noticing both of their skill, immediately went and spoke to Gojo, and they decided to "convince" the higher ups to let them come back with the Fireteam. They were successful, and after explaining to Leo and Nezuko,
=== Relationships ===
==== Leo Teich ====
Lucifer had a very close bond with Leo. After meeting Leo on Planet-089A, Lucifer took a liking to him, and after consulting Gojo, managed to convince the higher-ups to let Teich join Fireteam Zero. Although they are polar opposites, Lucifer being loud, energetic, hyper and kind, with a hidden mean and angry side, and Leo being quiet, calm, relaxed, and usually brutally honest, with a hidden caring side, they get a long very well, growing to be extremely close in the 6 months they know each other. After this, Leo was taken by Muzan. When they meet again, under different circumstances, they are against each other. A mix of the struggle of fighting his former best friend, desperation to beat him and protect the others, and rage after Leo hurt Nobara, is what eventually pushed Lucifer to discover his Super Saiyan form. Outside of combat, Leo and Lucifer tended to speak in person, as Lucifer had given up trying to message Leo. This was because Leo responded to nearly everything with "damn, fair enough", and engaging in no further conversation, where as in person, he actually spoke to Lucifer, although Lucifer is began to fear that would end soon too. Whether Leo spoke in person because he couldn't get away from him, or whether he actually liked him, no one knows
