Lucifer (Return of the Prince of Darkness)

Lucifer the most powerful Devil to exist and the husband of Lilith. He was once the first, and the strongest of all the Seraphim, before he turned from God. Along with the original Beelzebub, Leviathan and Asmodeus he ruled over the Underworld and led a war against God and the Angels. He is also known as: Morning Star, Prince of Darkness, Strongest Devil, The First Devil, The Devil and many more.

Appearance
He is a handsome teen, despite being one of the oldest beings. He has light silver hair, some might consider it as white and blue eyes.

His outfit varies, but he often wears a black leather jacket, white shirt, black trousers and a loose white belt. Either that or a suit.

Personality
Lucifer is very manipulative, which means that his true personality is somewhat of a mystery. He alters his actions when he needs to as long as it can gain what he wants, although he has shown to care for those that he considers as his, such as his peerage and when angered is brutal, with no consideration to what is around him or how it might look, as such his wrath is not something you'd wish to obtain.

He holds disgust for most Angels as he was once one of them and sees them as ineffective. He believes that they should be more forceful in solving the worlds problems, but after the death of God he thinks they have become somewhat redundant, or at least their time keeping things as they are is limited due to the lack of power they hold and the impossibility that one of them can fill Gods shoes.

Early Life
He was the first angel ever to be created by God and ever since God was never able to replicate him. Having been the first he enjoyed being the sole Seraph for a long time and relished in his duties, obtaining even more power as he worked toward his fathers goals. When Michael was born he gained a younger brother that he immediately took to loving, but, his father began doting on the new addition and Lucifer began to feel jealous.

Heaven VS Greek Gods
Lucifer was not the first evil like most believed, the first threats were another family of Gods. In the first battle Lucifer led his fellow Seraphs, Michael, Uriel and Raphael into battle with many lower-ranked angels against Ares, the God of War and his warriors. While the angels battled against the warriors Lucifer singled out Ares and their battle literally shook the world, Lucifer let loose all of his strength on the God and achieved victory, wiping out the warriors that were close to him as well from the waves of energy that were generated and the shock-waves that were created by the collisions of the two Godlike beings.

Lucifer continued to grow in strength as the battle continued, but he saw another side of the world during the war, he saw what humanity could become, their involvement in the war unleashed chaos, he witnessed humans killing one another and using the war as an excuse to commit atrocities that should never be permitted. The war didn't end for hundreds of years, Ares the main driving force for the limit number of Gods that fought as part of the Greek Pantheon, as many of the Greek Gods were yet to be born. God, the God of Heaven, was tied up with matching whatever move Zeus made and tried to limit the use of his own power through fear of what damage he might inflict upon the world and left the duty of protecting humanity and quelling the Greek Gods up to the Seraph.

As Michael gained confidence and the much needed loyalty of the other Angels he became the second general in the forces of Heaven. Eventually, Michael came to face Ares and the result of which was the first clear loss for Heaven, Michael being one among a dozen survivors for his army.

Lucifer's Betrayal
As the bloody battles continued Lucifer began to become more twisted and as his mind changed as did his wings. Eventually he took to hiding them so that no one would know and used the excuse that they would be vulnerable. However, Lucifer wasn't alone in his opinions, a Demon by the name of Beelzebub shared his views, and with one decision that would change the world he used his powers to enhance the Demon and created the first Devil.

Lucifer did not leave the armies of Heaven immediately, instead he returned while Beelzebub gathered others of like mind to create a new side.

Fighting a war on both sides the Greek Gods were forced to withdraw from thee conflict, but Lucifer saw the weakness in his father, he saw that his love for humanity was blinding him to the monsters that he had created and turned from his father, removing his own wings before the other Seraphs and replaced them with Devil ones before killing all of the Seraph but the first three (the first three if you exclude him) before facing his father. Lucifer was defeated, but he managed to injure his father, proving that even he could be killed if the person was strong enough.

At some point he and three others became rulers over the underworld and started a war to obtain the resources that they needed to live in their new home, which triggered the Great War.

Great War
Lucifer, Beelzebub, Leviathan and Asmodeus, the only Devils, lead the demons in the war against the angels in yet another fierce conflict, although their battles took place in the Underworld as opposed to Earth and no other mythologies took part. At some point during the war the 72 Pillars were made and the war became more balanced. Azazel and other angels split from Heaven, but in a more peaceful fashion than Lucifer had, becoming Fallen Angels as opposed to Devils and worked as the third of the Three Great Factions in the war. He also married Lilith at some point during this time, either prior or after Azazel became a Fallen Angel it is not known.

Plot
After being killed by Raynare as Issei Hyoudou he woke up, for some reason he had his teenage body back, but he knew he wasn't at full power.

Powers and Abilities
Immense Demonic Power: He has more power than any other Devil, he is regarded as the strongest of all Super Devils and even the new generation, which includes the two Super Devils Sirzechs Lucifer and Ajuka Beelzebub, are considerably weaker. Although the extent of his strength is unknown to all aside from the original Seraph and Beelzebub, which is why Sirzechs and Ajuka are mistakenly thought to be stronger than he and the other Four Great Satans. Bloodline Powers: He has all of them, but he cannot remember them all and would struggle to use them in combat as he has never used each one of them.
 * Power of Destruction: He has the original Power of Destruction, a mixture of blue and black energy that is stronger than the power the Bael family has.

Immense Light-Based Weapons: He retained all of his angelic abilities and among these was his ability to create weapons from light, although using the powers does cause him some discomfort due to him being a Devil.

Master Magician: He is very experienced with magic and was the origin of much of it, he and Beelzebub created Demonic magic and he even knows magic from other factions. He was taught well with angelic magic as well, having been taught by God himself.

Master hand-to-hand Combatant: He knows all old martial arts and his lives as humans has taught him more due to his leading of a normal life.

Weapons Mastery: He has mastered all weapons over his long life and reincarnations.

Flight: He can fly using his wings.

Weaknesses
Currently his largest weakness is the drained state of his powers, despite returning to his Devil form most of his powers have been completely sealed and it will take time to access them fully. He also can't take on his true forms for the same reason.
