Laplace

Laplace (ラプラス) is known as the Demon God, a title given the strongest Demon, who waged war against humanity 500 years ago before being sealed by the Seven Great Heroes. In reality, there are actually two Laplaces: Demon God Laplace and Technique God Laplace. Both were originally one entity but ended up splitting into two while fighting the Fighting God.

While the Demon God never actually appeared in the main story of Mushoku Tensei, he will likely finally debut in the planned sequel series, during which he is set to finally reincarnate.

Background
""Alright. If the Demon God neglected you for so long, he wouldn't mind if I just take you away, even though there are so many uses, what a waste...""

- First Dragon God

Even Laplace himself does not know where he was born. Ever since becoming aware as a child, Laplace found himself in a cave at the corner of the Demon World, a land of death, full of miasma and roaming demonic beasts where he goes hunting monsters for food and sleeping on a regular basis. Laplace soon felt lonely after witnessing some demonic beasts huddling and playing with each other and decides to wander and finds a demon town but its inhabitants viewed him as a monster and the Demon King of the town fought and injured him but he manages to escape. Laplace would eventually encounter a hydra that spits fire and poison mist where his injuries from it would not heal like it normally does after eating and sleeping.

On the brink of death, Laplace is saved by the First Dragon God and brings him to the Dragon World, an inverted land where the mountains grew from above while a clear blue endless sky and white clouds is seen below. Upon arriving at the First Dragon God's home in Kayos, Lunaria greets them and the First Dragon God tells her that he plans to raise the child with her and gives him the name Laplace.

Laplace is then trained by Dora at the command of the First Dragon God to become a Dragon Warrior and for the next decades, Laplace is trained on how to speak the Dragon God Language along with different subjects about the Dragon World, how to use Dragon Battle Aura and how to fly. After completing his Dragon Warrior training, Laplace become Dora's subordinate and his first task is to train dragons that are the mounts used by the Dragon Tribe. This is where he first meets a red dragon who was initially hostile towards him but eventually is able to tame him names him Saleyakt and afterwards he would rose into prominence because of his ability to train dragons that are considered untrainable by traditional methods.

Demon/Magic Dragon King Laplace was the sole survivor left of the Five Dragon Generals after the incident which caused the inhabitant of the four destroyed Worlds to escape into the Human World and the collapse of the Dragon World. He was the second generation Dragon God after the first passed away.

Laplace escaped the collapsing Dragon World and drifted to Human world. He became the second generation Dragon God. He researched about methods and techniques to overthrow Human God. He taught to those who called themselves `Dragon God` the techniques he had developed over a long time. All for the sake of passing down the power to Orsted who came to the future, and said to possessed the greatest strength among the dragon-tribe.

He went to human-demon race world war where he fought against Fighting God who was Human God`s apostle and his soul was split into two halves. Laplace, who was split in two, lost his memory and became two, the human-hating [Demon/Magic God] and [Technique God], whose aim was to overthrow god.

[Demon/Magic God] Laplace lost the power of dragons. He only remembered the enormous amount of magic knowledge and that he must definitely kill 'human' forgetting the God part. For that purpose, he rallied the demon race to exterminate the 'human race'. He was cursed the same way Orsted was, however he was able to transfer the curse to the Superd race.

[Technique God] Laplace who lost the power of magic, only remembered the enormous amount of techniques and that he must definitely teach and pass them down to someone. Thus Technique God created the Seven Great Powers ranking and devoted himself in studying those techniques.

Mushoku Tensei Sequel
Since the planned sequel series seems to be taking place around the time which the Demon God Laplace would finally reincarnate, it is very likely that he will finally make his debut here. Particularly, he is set to play a vital role in several major storylines. Most obvious is Perugius' quest to finally kill him for good and avenge the members of the Seven Great Heroes who died whilst sealing him 500 years ago. However, he is also set to be deeply involved with Orsted's quest to kill Hitogami, since he holds the final key the former needs to enter the latter's realm. If the events play out like in Orsted's previous loops, then Ruijerd and Norn's daugther, Luicelia, will play a major role in his eventual defeat.

Dragon Battle Aura

 * Trained by Dora to be a Dragon Warrior, Laplace's Fang Technique has enough destructive power to be considered "deadly" and is among the few Dragon Warriors who can match Dora in combat.

Although he admitted he did not know how to activate this ability.

Demon Dragon God

 * Before he was split into two beings, Laplace was considered the most powerful entity in the world. as one of the Five Dragon Generals he had enormous physical strength, night vision and a demon eye that allowed him to track and sense enemies. Laplace could also fly.

Technique God

 * Technique God Laplace has the Dragon Power and knows many techniques in the world to overthrow 'God'. He created the Seven Major World Power system and ranked himself 1st. But, he loses some part of his memories, leading him to only remember his objective is to overthrow 'God' by teaching those who call themselves Dragon God all of his technique and lost all of his Magic Power, making him unable to use magic.

Demon/Magic God

 * Demon/Magic God Laplace has the enormous Magic Power and a master of all magic. He lead the demon race to exterminate 'Human' 400 years ago and ranked 4th in the Seven Major World Power system.
