Since I'm finally almost done with the Musashi Thread, I'll start on the Dioscuri Preamble and basically remove this when I work on it in earnest:
The Brotherly-Sister Duo that only has a bit of incest teasing? The hell have I heard that from...
Either way it's Dioscuri(Yeah, I was supposed to do them before Musashi but... you saw that humongous wait for Musashi...)
If you are wondering if I will add their Lostbelt Selves? No, I won't, it's basically pointless to even do so. Outside of Pollux being an enabler and Castor being even more bloodthirsty than he was before, there's no virtual difference. Also FYI, all of their feats are obviously considering the both of them together because while going by legend, Pollux would be a better boxer than Castor and so on, ingame they don't appear to be THAT vastly different so while I will be clarifying who does what, they both share one Saint Graph and Divine Core so it doesn't matter.

Figure within FGO
Gleaming twin gods who stand back to back.
At their core, they are ancient Divine Spirits who manifested with unique properties when they were summoned.
Although they are the same entity, they have two bodies, and each body holds their own differently-Classed nature.
In other words———
There is the elder brother, Castor, who received the legend of being a “child of man” without the blood of Zeus from later generations, and having turned the humiliation of falling from god to human into hatred, appears as an Avenger.
Then, there is the younger sister, Pollux, who received the legend of being “immortal” and carrying the blood of Zeus from later generations, and now continues to fight with her vicious swordsmanship and her body that knows no wound, appears as a Saber.
Their registered Spirit Origin is a Saber, but more accurately, they are a kind of Double-Class Servant.
Their special characteristics are likely exceptions due to them being Divine Spirit Servants.
◇
The Dioscuri are always cuddled close together[1], and so are never separated. One could also phrase that as them ‘never being apart from one another’. They are two people as a single Heroic Spirit.
(Actually, as Servants they are basically never more than a few metres away from one another)
◇
When the Fifth Lostbelt was first generated, they materialised as living gods.
The twin gods were defeated by Kirschtaria Wodime, and having lost their lives once already, formed a contract with him as Lostbelt Servants.
Through that contract, Castor learned of the legends of “their Proper Human History selves”, and despite those being Proper Human History’s affairs, began to harbour an immense loathing for humanity, which had so denigrated him.
Pollux too began to hold a deep grudge against humanity for looking down on her brother.
Consequently, both siblings were filled with the flames of a deep-seated hatred, and began to behave in a consistently cruel, violent manner towards both Chaldea and the citizens of Olympus.
In contrast, the twin gods summoned to Chaldea as Proper Human History Servants do not have the same fiercely violent nature as their Lostbelt Servant version.
While Castor has a nature and history sufficient to manifest with an Avenger Spirit Origin, his sister Pollux has a much gentler personality compared to her Lostbelt self. Because his sister is present to chide him, it is alright, to some extent, to let him loose.
Class Skills
Mad Enhancement: B- A skill possessed by the sister, Pollux.
Mutual communication is possible, but the parameter-increasing effect has been limited.
However, if her brother is severely wounded, she will fly into a frenzy and be almost impossible to communicate with, becoming the very incarnation of aggression.
Surprisingly, it pops up in her NP lines and here and there so no need to actually bring in examples.
Magic Resistance: A As a Saber, it’s natural that Pollux has a high Magic Resistance rank.
Not really shown anywhere.
Riding: B Pollux has talents in the Riding skill, due to being a Saber.
Again not really shown anywhere
Avenger: B As Castor, the brother, is an Avenger, he has this Avenger skill naturally.
It is a skill that symbolises his vengeful desires against humans.
Again, basically stated in their ingame profile and Castor states it all the time so it's meaningless to bring it here.
Oblivion Correction: C Brother Castor has the Oblivion Correction skill due to being an Avenger.
He will never forget that he is, himself, a fallen god.
Self-Recovery (Magical Energy): D As an Avenger, it’s natural that Castor holds the skill of Self-Recovery.
Divine Core of the Twin Gods: B A skill possessed by both twins.
Ordinarily, due to being ancient twin gods, the rank should be A, or even non-standard, but due to the influence of the twin’s legend within the Grecian mythology that took form in later years, it stops at B-rank.
In particular, it is likely because later versions of the legends considered the fact that “Castor has no divine blood” in their tellings.
I would bring it up but again, it's effectively told in Olympus and the foundation of their legend so pointless to bring up.
Personal Skills
Star of the King of the Gods: A A skill that symbolises the way of being of the twin gods, who have become a single entity as a constellation.
They possess the legend that they were ancient gods of the stars, who were turned into a constellation by Zeus. It demonstrates the way of being they both possess, not just that of one or the other.
Never popped up in the story(seriously sorry, despite my long ass absence on these due to alot of deals, they don't give anything on what these Skills
do for most of them outside of the obvious)
Guardians of Sea Voyages: B They bring protection to those who travel by boat.
The existence of the twin gods fills the people in the area around them with hope, invigorating them to surpass any obstacle.
It is a skill that resembles the Voyager of the Storm skill, and is intrinsically a composite skill that contains Charisma and Tactics.
Not used in the story.
Mana Burst (Light/Ancient): A These twin gods are, themselves, the light of St. Elmo’s Fire, which flickers on the sea.
It is similar only in appearance to the subspecies Mana Burst that some Saint-type Servants use.
They can release magical energy in the form of light to power themselves up.
While not stated exactly, it is all but implied it is basically where the bulk of their strength and speed manifests from(Which I will catalogue it all later)
Noble Phantasms
『Praiseful Song of the Twin Gods』
Rank: B
Type: Anti-Unit Noble Phantasm
Range: 0~3
Maximum Targets: 1 person
Dioscures Tyndaridae.
The talent of Pollux, who is said to be a swordmaster, and the might of Castor, who resents his fall from his place among the gods. It is a perfect and complete combination attack, unleashed by the twins who continue to snuggle[1] together in the heavens.
The coordination of their special move is born from their tremendous trust in one another, and now sublimates to the realm of a Noble Phantasm.
Furthermore, if only when they release its True Name, the two are able to almost completely recover the Divinity they held as ancient gods, and their Divine Cores will temporarily be of the greatest rank. As they attack after exercising near-absolute Divine Spirit-scale magical energy, they ignore all physical and magical obstacles and defences, and pulverise the target into nothing.
Surprisingly not used in the Story, believe it or not(You think Lostbelt Castor would be all over using a True Name Release to puff himself up moreso).
『Starlight Shield, Starlight Sword』
Rank: B
Type: Anti-Unit Noble Phantasm
Range: 0~3
Maximum Targets: 1 person
Alpha Castor, Beta Pollux.
Their armaments are Noble Phantasms in and of themselves, radiant starlight being turned into a shield and sword respectively.
The shield has a Conceptual Defence effect when its True Name is released, but that is fundamentally not used in “FGO”.
While the story never shows the Conceptual Defense being used, the weapon and shield themselves are stated to be created from Adamant(the same as Achilles Shield and Armor and Odysseus' Aegis) in their Bond Craft Essence.
Feats(Strength, Speed, Durability, etc.) To basically get into the entire meat and potatoes, Dioscuri is consistently described(as well as they themselves state) to be able to move as fast as light on multiple occasions:
I'm bringing these in here just to ultimately get it out of the way along with the proof I have in a certain Threadmark(which I swear I will change around due to even easier info and ways I can point out the flaws) because otherwise, I would be here all day stating the obvious.
Also, a few of their feats will also come from the Musashi Thread so here you go:
Here, Mash simply speaking about Castor causes him to lash out in murderous rage and anger and aims an immediate killing blow that Musashi blocks.
Here, while Musashi talks shit about Castor's attack, in her head she's utterly freaking out over how strong and fast it was even comparing it to light itself to the point no Sword Saint could match the attack Castor pulled off.
Here, Musashi states she's glad Holmes prepared a support spell in advance or Mash's head would be long on the ground otherwise.
Here, upon Castor attacking Musashi, Musashi states if she planned on sacrificing herself, she could atleast take down either Castor or Pollux with her but not with the risk that the other would still be alive or both at the same time(This fits Nasu's statement that Kojirou going all in against Heracles can take off a life but die doing so)
Now to get to their actual exclusive feats for themselves past the most obvious:
Here, Meuniere states that behind Kirschtaria is 2 Servants that are registered as one but are ultimately recognized as Divine Spirits onpar, if not stronger, than Caenis.
Here, when Dioscuri takes Caenis away on Kirschtaria's orders, Jason states they didn't kill Caenis yet into goading Dioscuri into a fight but Orion in his mind all but implies with his words that despite the Servants on their side(Mandricardo, Jason, Chiyome, Mash and Orion himself), Dioscuri would have trounced them.
Here, Musashi states the group of enemies have such intense magical energy, it surpasses Talos(
Whose already on the level of Divine Spirits as is). To be fair, you could say it's the combination of beings that surpasses Talos but it's obvious from Musashi's statements that even one of them surpasses Talos.
Here(Surprisingly using an Event of all things... really should do that more often), it's stated that while all of the Mallet's wishes work on Servant Spirit Origins instantly, for Dioscuri it took awhile to actually work.
Here, the Mallet's wish finally works and they immediately ascend to their Third Ascension and Mash states their powers have increased tenfold and can't be stated to be Heroic Spirits anymore but Divine Spirits.
Here, Musashi states despite Mash doing better in blocking their attacks, Caenis and her spearplay and Caligula still going strong despite his injuries and Musashi herself, they are still too equal and it's ultimately a battle of attrition.
Here, Holmes shoots a Beam of Light at Dioscuri who treats it as nothing but Holmes states that while they are Divine Spirits of Light capable of near-lightspeed, they can't nullify all forms of light.
Here, Holmes believes that if this means they can exploit openings due to that while Caenis pretty much tells him he can't do shit against them regardless.
While I took a pic of this, I wanted to get it in particular here:
Here Castor, completely frustrated by the God Slayer Alliance gaining the advantage, zeroes in on Ritsuka and uses his Authority of FTL to ambush Ritsuka and chokes the life out of them.
Here, Pollux realizes Castor is bleeding from his mouth from doing it and states basically the above can ultimately destroy their Spirit Core as they are only Divine Spirits now while Castor brushes it off(It's ultimately hard to state if Dioscuri did take real damage from this or it's a slow degradation to death. Meltryllis went a much further distance up and despite basically being a Divine Spirit herself, took awhile to break apart and an actual 2nd use to truly die completely meanwhile Castor is just damaged but Pollux's concern does bring still bring up the potential possibility).
Here, upon Castor getting spooked and throwing Ritsuka after finding out they are the ammo to the Black Barrel's Lifescale, Caenis goes for a double attack upon him and Pollux.
Here, Marcarios and Adele use a joint AoG Magecraft from Hades and Athena to take down Dioscuri.
Here, the aftermath where Castor and Pollux are basically utterly wrecked and basically vanished after getting some questions asked, answered and going down spiteful.
Okay, now I SERIOUSLY apologize for this one, considering this was me just being lazy as hell for months and seriously taking way too much time off.
