These Servants are those who were hailed as a hero despite their wishes, sacrificed for a greater purpose, were betrayed or had betrayed someone in some manner or form, or were killed wrongly. For example: Ariadne, Medea, and Polyphemus (Cyclops) would qualify as an Avenger Servant. All those summoned into this class have the Class Skill “Vindication” that greatly enhances the stat of one of the Avenger’s choosing if they are facing a foe that is stronger than them. For the way this works, is by adding up their numerical stat values; allow me to explain with this example here:

Cu Chulainn’s numerical stats are as follow: 40+30+50+30+10 which adds up to a total of 160.
Iskander’s Numerical stats are as follow: 40+50+20+30+50 which adds up to a total of 190

So, if Cu was an Avenger he’d get the difference, which in this case is 30, in one of his stats of his choosing, which is a mighty fine boost. While the math is tad annoying, the reward, as you can see, is well worth it and can level the playing field quite quickly.
As a final added bonus for the Avengers, Spirits summoned into this class also get the skill “Battle Continuation” for another one of their class skills as well. Those who already have the skill get theirs increased a rank higher at my discretion.

Now we come to the Servants who have been summoned into the Beast Class. These Servants are the great beasts of legends whose death would make their slayer a famous hero. Basically, spirits summoned into this class are the ‘great beasts’ or ‘creatures’ of legends that were slain and used to make their hero more famous. Examples of Beast class Servants are: The Nemean Lion, Fafnir, Fenrir, The Minotaur, The Hydra, Scylla, Wendigo, and other famous creatures. Those who are summoned into this class have the Class Skills “Transformation” and “Monstrous Strength”.

Transformation is theoretically Shapeshifting, however, this is a more advanced version that allows its user to alternate between their humanoid form and their ‘true’ form, along with anything in-between in mere seconds. Naturally, those summoned within the Beast class already have their basic abilities; such as a signature ability that was theirs in life. This ability would be at their disposal no matter what form, but the closer they are to their true form, the stronger the ability is. Upon taking one's true form, they gain resistances and numerous skills reflecting those that they might have had in life. But as a result of transforming to their truest form, their identities are automatically revealed to all.

Class: Avenger

Master: -If applicable-

True Name: Perikles, Founder of the Athenian Empire, Chosen of Athena & Zeus, Predecessor to the King of Conquerors

Gender: Male

Height/ Weight: 6'1, light

Alignment: Lawful Neutral

True Appearance: As pictured, Perikles wears the blues and silvers associated with the Athenians of his time. He has an iconic silver Corinthian design helmet of Athenian make, standard issue for the Greek Hoplites, with a blue plume atop it in a parody of Spartan officers. He is summoned with a xiphos, bow and a hoplon all of high quality, as befitting a hero such as himself, but they are not notable weapons in and of themselves, merely tools of combat he was well acquainted with in life.

Outfits:

Personality: Tsundere idealist. Perikles longs for the world to be better than it is, believing that a united world would ultimately be a beautiful one, but hides this under the cover of 'necessity' to people. It is not about what he wants, Perikles would claim, but about what the people need. He could be viewed as quite the morbid individual, but this was not always the case. After the death of his two legitimate heirs due to his own failure as a general, grief overtook him, and he too suffered the same fate not too long after his legitimate children. Now summoned, the memory of his slowly dying children weighs on his mind.

When love strikes Perikles, it does so very hard for both the platonic and romantic. Perikles' relationship with Aspasia of Miletus, his mistress, was as public as his official marriage, unashamed and intense. Even in the face of slander, he stood strong beside Aspasia and even showed tears for her sake before his fellow Athenians. For his friends and lovers, his is unyielding to an unearthly extent.

As a Servant, he is unusually aware of his own weaknesses, going out of his way to avoid a direct confrontation with another Servant with the knowledge of his comparative physical weakness to many other heroes, especially the Knight classes. If he does face a foe, he would rather it be on his terms where he has the advantage, through a proxy servant, or simply not at all. This does not mean he simply would not fight someone if faced with that dilemma - he is, after all, supposed to be summoned under the Lancer class.

As far as Masters go, he is likely to best operate with a summoner who understands that in life he was a General and a tyrant, and as such would much prefer to take the lead in terms of strategy and direction. But, again, Perikles understands the significance of the War to both himself and his master, and so if he believes it best he will take a back seat. Better a team following a bad idea together than a team trying to follow several different good ones, after all.

Stats:

Strength: E

Endurance: D

Agility: C

Magical Energy: B

Luck: C

Class Abilities:
Vindication: Stat discrepancy between Avenger and a servant of a higher number is calculated and then added to one of Avenger's stats, increasing its rank.

Battle Continuation: B - For an amount of time Perikles can remain standing after taking a grievous wounds, but not to the extent of taking a lethal blow and continuing to fight.

Personal Skills:
Charisma: B

Disengage: B

Strategist: B - Through out the course of the war, Perikles can easily discern the 'best course of action'. However, this is only the theoretical best course, and can still go poorly for him and his master. In his legend, this can be seen in the implementation of the Walls of Athens.

Olympian ~ The Weapon of Zeus
Rank: B
Type: Anti-Unit
Range: 1-500
Maximum targets: 5

Socrates, Plato, Aristotle, Quintillian - classical writers of Perikles' era and beyond exulted his talents. To them, he was "thundering and lightening" who "excited Greece". According to Arsitophanes and Diodorus, he carried the "Weapons of Zeus" with him. This Noble Phantasm is not a singular weapon, but a state. Perikles pulls down his helmet, eyes igniting with blue energy, spilling out from the visor. Storm clouds rapidly form above the battlefield and rain begins to patter, steadily increading in volume to the sound of gathering thunder. Lights streak horizontally through the clouds. At this point, battling Perikles becomes a risk for any foe.

His body acts as a beacon, and his weapon a targeting point for divine lightning. Any strike, block or parry risks calling down the wrath of Zeus so long as Perikles is as an "Olympian" with the "weapon of Zeus" at his side. This Noble Phantasm also allows for his summoning as Lancer, as it can be used for less mana to increase his agility to A+ rank, however that capability is lost with the Avenger class.

Treasury of Delos ~ Tribute to Athens
Rank: C
Type: Anti-Betrayal
Range: 3
Maximum Targerts: 1

In the days of the Delian League, the city states that once paid tribute to Persia instead did so to Athens in order to have them 'handle' the Persians. In the end this came back to bite the city states, so to speak, and allowed Perikles to solidify the Athenian Empire.

Perikles grants 1 rank up to all stats of 1 servant other than himself, and increases their own mana reserves in exchange for an alliance. This alliance operates under a pseudo-geas; the moment it is broken, the boost is transferred to Perikles, and the impacted servant suffers a rank down to their original stats.

PARTHENON ~ Guidance of the Heroes Companion
Rank: C
Type: ??
Range: 30
Maximum Targets: 30

One of Perikles' most notable feats, and one that is still with us today, is the construction of the New Parthenon which was done under his order. With Guidance of the Heroes Companion, Perikles recreates this feat to a lesser extent.

He claims a building in the name of Athena, turning its interior into that of a temple of the aforementioned god. The inside of this building usually becomes larger than what was once there in an odd shift of reality. When inside the PARTHENON, Perikles and his master recover mana at an increased rate, as well as the servant and master under the Delos geas. On top of this, Perikles may use Olympian free of mana cost while inside PARTHENON. It is the ultimate war room for Perikles and his allies.

This structure is difficult to detect, hidden behind a complex and powerful bounded field which creates a sort of bystander effect when it is looked for. Athena is, after all, a god of wisdom and warfare, and sometimes warfare must be subtle.

(Like Rank C- or D, whichever one works)

Throne of Solomon: Allow him to mark a building as his throne. This building is then guarded against attack by several golden statues that come to life whenever someone with hostile intent is near.

Gender: Male

Height/ Weight: Unknown

Alignment: Unknown

Personality: The Overseer’s personality is odd, one that he doesn’t show with his never changing face.

For that is his duty in the end as the Servant Ruler.

Saint (-): This particular ability grants him an increase in recovering from his wounds.

Personal Skills:

Mystic Eyes of &@#$% (EX): An unknown pair of eyes that Ruler possesses that are unlike any other, surpassing the Mystic Eyes that are on the current spectrum that they are unrecorded. The only details of what kind of eyes he possesses, or what powers they hold, are the glittering diamond infinity shaped eyes he has in both eyes, and the dual pupils and irises he has.

Noble Phantasms:

??? (???): A strange old fashioned telephone that you have to turn the numbers to dial. A mystical telephone you say? Nope. An average normal telephone? Who knows! It’s a telephone! All that one can say is that it is ringing constantly… but it isn’t? It’s ringing in the back of the head of every Master and Servant, catching their attention, but at the same time they can’t notice it. It’s there, but it is not. It’s just a telephone after all. A simple… simple, telephone belonging to Ruler. He plays with it, dials it, and just stares at it all day long… perhaps he’s just wondering if he should just get a better one. No one knows… except Ruler. No one other than Ruler himself can touch this phone; or attempt to do anything to get ahold it. It is simply an impossible odd.

Rulers other Noble Phantasms haven’t been revealed yet.
