Ruler (Fate/Crossover - Optimus Prime)

**Ruler** (ルーラー, *Rūrā*) is the servant of ??? in the ??? Holy Grail War.

"*Freedom is the right of all sentient beings*." - Optimus Prime's motto

## Profile

### Identity

Ruler's true identity is **Optimus Prime**, Leader of the Autobots, and descendant of the Primes.

Originally, he began life as Orion Pax, a humble data clerk under the mentorship of the ancient sage Alpha Trion. He became close friends, almost brothers, with the gladiator Megatron, as both of them sought to address the corruption and inequity that plagued Cybertron. However, their differing methods and ideologies on how to achieve those goals culminated when Orion's ideals of peaceful reform were accepted by the Cybertronian High Council over Megatron's aggressive, radicalistic ideals. Feeling spurned by the one he called his brother, Megatron severed all ties with Orion and rallied the Decepticons to forcibly seize power for himself, plunging Cybertron into The Great War. Orion was bestowed the Matrix of Leadership to become Optimus Prime, realizing his destiny as the last of the original Thirteen Primes. Optimus would lead the Autobots in eons of war against Megatron and the Decepticons, which eventually led them to Earth.

### Personality

Optimus Prime is a paragon who's most defining characteristics are his strong sense of honor, justice, bravery and morality. His charisma and wisdom are enough to rally groups of quarreling, disparate Autobots into cohesive, mutually respectful units.

Optimus most of the time is seen as a stern, serious leader, even having a bit of a ruthless streak on the battlefield, giving no quarter to those who threaten his allies or innocents lives. After fighting for millennia and always feeling the numerous losses of life, Cybertronian, human, or otherwise, weighing on his spark for as long as he has, Optimus is permanently conditioned to look at the big picture over the well-being of the individual. He feels immense pressure to lead and spends most of his time doing so, even when R&R would benefit him.

While the furthest thing from shy after becoming a Prime, Optimus is not particularly social, and does not always get to know those around him on a personal level. When he does socialize, he is straightforward to a point, and rarely taking jokes or engaging in any sort of lighthearted banter.

### Relationships

#### **Megatron**

Optimus once looked up to Megatron as a mentor, eventually becoming a brother figure, bonding over their shared dream of a better Cybertron. Unfortunately, Megatron let his ambitions of power corrupt him and the two found themselves on opposite sides. In spite of their never ending feud, both of them hold a deep respect and understanding as worthy opponents. Megatron even believed that if Optimus wasn't so caught up in such naïve idealism, they could've ruled together.

#### **Ultra Magnus**

In many ways, Ultra Magnus is a brother to Prime, similar to Megatron before his fall to evil. As one of his most trusted lieutenants, Prime will defer command to him whenever he is unable to lead anymore, even passing over the Matrix despite the latter's reluctance.

#### **Grimlock**

Optimus often finds himself at odds with the Dinobot leader, who barley tolerates his leadership due to his arrogant and impulsive attitude. At the same time, they both commit themselves to the Autobot cause of defending the defenseless.

## Abilities

Optimus Prime is invariably one of the strongest Autobots of all, especially with immense power granted to him by the Matrix of Leadership.

As a veteran soldier and warrior, Optimus is a formidable opponent in battle as he possesses great strength, endurance, and agility. In addition, he is a master of numerous forms of armed and unarmed combat, wielding veritable arsenals of weapons, from blasters, to axes, to hooks, to swords, all with extraordinary skill. All his combined abilities effectively make him a one man army, as proven by him easily defeating armies of Decepticons, and fighting on par with their heaviest hitters; from Megatron himself, to combiners like Devastator and Menasor.

As leader of the Autobots, he is a highly experienced strategist and tactician. Combined with the additional wisdom of the Primes from the Matrix, he has led multiple battle fronts and counter strategies against Megatron for millions of years.

### Skills

#### Class Skills

* Magic Resistance (A+ Rank): Due to carrying the Matrix of Leadership, and thus a fragment of the spark of Primus, Optimus boasts exceptional Magic Resistance. The only form of “Magecraft” or “Magic” that he appears susceptible to originates from the Primes or other ancient Cybertronian deities.
* Riding (C Rank): Optimus has been trained to pilot the starships and vehicles of his home planet with adequate, though not exceptional, skill. He is also capable of riding into battle certain massive creatures or allies such as Grimlock.

#### Personal Skills

* Divinity (A Rank): Optimus was one of the Thirteen Primes, the closest analogue that Cybertronians have to a pantheon of gods. He chose to be reborn in the Well of All Sparks as a normal Transformer, a descendant of the Primes, but his legacy lives on, as evidenced by the Matrix of Leadership deeming him worthy to possess it. This Divinity, along with the Matrix itself, grants Optimus his excellent Magic Resistance.
* Battle Continuation (A++ Rank): Possessing exceptional durability even among Transformers, Optimus has managed to win, or at least escape from, numerous battles in which he received ludicrous amounts of damage. As a general rule, compromising Optimus’ body will of course, hinder his combat abilities as his limbs and weapons are reduced, but he will continue to fight on unless his brain or spark are destroyed in a single, decisive attack.
* Military Tactics (B+ Rank): As the last Prime, Optimus has led the Autobot faction for at least hundreds of thousands, if not millions of years, experiencing countless clashes with Decepticons, aliens and (in recent times) even humans. A true veteran of war, he is able to devise excellent strategies with very little time and information, even when facing a superior hostile force.
* Charisma (B+ Rank): Going hand-in-hand with his Military Tactics Skill, Optimus has developed into a phenomenal leader. Once, the Autobot Crosshairs remarked that Optimus’ leadership was so inspiring, it made his followers want to die for him. Indeed, the last Prime's penchant for grand, soul-stirring speeches at crucial times is enough to inspire the vast majority of those around him into facing down insurmountable odds. The only thing preventing Optimus' Charisma from being an A-rank is his fixed leadership style: the only way he knows how to lead is as a stoic, well-spoken war hero. He is somewhat less adept at reaching out to more disparate personality types in ways that would suit them best.
* Bravery (A Rank): Millions of years of warfare have hardened Optimus into an exceptional soldier. At this point, he’s virtually seen it all, and his discipline is ironclad. Mental interference from anything other than a divine Cybertronian source is, for the most part, totally ineffective.
* Transformation (B Rank): Like all Cybertronians, Optimus has the ability to switch between robot and vehicle form at will. When he scans a vehicle, his body instantly reformats to adopt that vehicle’s characteristics, changing in shape, color and even repairing existing wounds. His preferred vehicle mode is a large semi truck cab.
* Eternal Arms Mastership (B+ Rank): Optimus retains the vast majority of his normal fighting skills no matter how extreme a situation he is in.

### Noble Phantasm

#### **Matrix of Leadership**  - "*Light in our Darkest Hour*"

One of the oldest artifacts in Cybertron’s history, the Matrix of Leadership contains a fragment of the spark of Primus, the multiversal creator-god of the Transformers. Occasionally Optimus can use it to commune with the souls of the original Thirteen Primes, seeking their counsel when the stakes are high or the future is uncertain. The Matrix has the ultimate emblem of Cybertronian authority since the beginning of time, like a royal seal of sorts: any Transformer it deems worthy is christened ‘Prime’ and named the leader of all of Cybertron.

Yet the Matrix is far, far more than a mere symbol. In truly dire circumstances, Optimus can call upon its power to vanquish his enemies in one of two ways. Drawing upon the power of Primus himself, the Matrix can generate an EX-level barrier of pure energy capable of withstanding any attack, even another EX-ranked Noble Phantasm. Once that attack finishes, though, Optimus has only a few seconds left, enough to attempt a single counterattack.

Should that counterattack fail to destroy or cripple his enemy for any reason, Optimus’ mana will drain completely, as using the Matrix’s power returns that power to Primus (along with Optimus’ own memories of being a Prime). As a result, Optimus temporarily regresses to his identity as Orion Pax, a docile data clerk with no wartime experience. Thus, his Luck, Mana, and Magic Resistance will drop to E-ranking, and all of his other parameters and Skills will drop to a D-ranking, making him easy prey for any Servant still alive.

If Optimus manages to escape the encounter, he will require several days to fully regain his power and memories, although a Master with high-quality Magic Circuits may accelerate the process. During this time, he experiences amnesia, remembering only parts of his life and lacking nearly all of the leadership and fighting instinct that Optimus Prime possesses. Needless to say, he is quite vulnerable during this period and needs his Master to keep him out of trouble until he recovers.

In the rare event that Optimus is assailed by an Anti-Divine Noble Phantasm, such as the Chains of Enkidu, the Matrix is able to counter that as well. By releasing some of the Matrix’s energy, Optimus temporarily forfeits his Divinity, reflecting the early days of the Great War when he was a great Autobot but had not yet ascended to the mantle of Prime.

This way, Optimus is able to render Anti-Divine Noble Phantasms ineffective for the duration of the battle, or for as long as he wants. However, by relinquishing the strength of a Prime, all of his Parameters and Skills are ranked down one level. Additionally, he is unable to wield any of his Noble Phantasms until he willfully regains his full power and Divinity.

The second way the Matrix can be called upon in battle is to unlock Optimus’ fourth and final Noble Phantasm, the Star Saber.

#### **Star Saber**  - "*Legacy of the Thirteen Primes*"

A weapon as old as the Matrix of Leadership, the Star Saber was forged by Solus Prime, one of the Thirteen Primes, and wielded by Prima, the first of the Cybertronians. In its original form, the Matrix itself formed the Star Saber’s hilt, and the exact details of its origin are known to none but the Thirteen. This sword of swords was said to be capable of crushing stars and reducing entire planets to fine dust, but much of it’s legend has been lost to the depths of history.

The Matrix’s fundamental connection to the Star Saber is what allows Optimus to summon the latter using the former. By the power of Primus, the Sword of Judgment is transformed into a weapon many times its superior. The Star Saber can rend almost any substance in the known universe, including A-ranked Magical Barriers, and unleash radiant cobalt shockwaves that cleave through skyscrapers.

A few vital implications surround the Star Saber’s use. First and foremost, Optimus can wield either it or the Matrix’s defensive force field, but *not both*. As soon as he commits to using one of these Noble Phantasms, he forfeits access to the other until the next time he is summoned as a Heroic Spirit. Optimus must choose between the all-out offence of the Star Saber and the invincible defence of the Matrix.

Secondly, the Star Saber’s ridiculous mana consumption means that Optimus cannot normally use it for more than a few minutes at a time. Prolonging the Saber’s active time (for another few minutes, that is) requires his Master to burn a Command Spell. Additionally, to reflect it’s eventual destruction, the Star Saber grows incrementally weaker each time it is summoned (i.e. the second time it is deployed, it downgrades to an A++ ranked Noble Phantasm, then an A+ rank the third time, and so on).
