What if the Fourth Holy Grail War had an additional Servant? What if this extra Servant was the single most overpowered jerk summonable? No, not THAT overpowered golden jerk. This one makes him look like a saint with the sheer abundance of his ego.
...
As he finished his prayers, the Assyrian queen manifested behind the young priest with her usual haughty demeanor.
Semiramis: Lancer was intercepted by the Saber of Black just before he could eliminate Ruler. They're currently fighting one another.
Shirou: Then the Great Holy Grail War has officially started. Are they there?
Semiramis: If by they, you mean the independent Servants, then yes. They have simply adopted the role of spectators for the moment.
Shirou: So they have.
Semiramis: But, are you certain of their identities? Not that I should be so surprised, but even that has limits. Divine Spirits, much less primordial gods, cannot be summoned as normal Servants. Though, I suppose their Independent Manifestation is at fault.
Shirou: That's right. Though, I am not worried about Tiamat. She will have a passive role.
Semiramis: *sarcastically* Ah, yes. She doesn't want to harm her children, does she? How very thoughtful of her.
Shirou: I find it to be rather admirable. Regardless, I suspect the primary threat is the Foreigner.
Semiramis: What was his name, again? I don't recall a hero of his name.
Shirou: Correct, since he's not a Heroic Spirit. He's a genuine living being that decided to manifest as a Servant.
Semiramis: And you see someone like that as a threat? Is there such a thing as too paranoid?
Shirou: I wouldn't be so sure. Every single one of his skills is at EX-Rank, save for A-Rank Divinity. It's best if we stay our hands from now since he could sense any attack before it even starts.
Semiramis: Hmph. In that case, then perhaps I should hasten the creation of the gardens.
Shirou: I would appreciate that. The ritual should be complete in a few days, no?
Semiramis: Yes. There are no issues-
???: I HAVE ARRIVED! I say, you both seem to be in a good mood!
The entrance doors were suddenly open with a bang as another Servant of Red made his arrival with extreme charisma and hamminess.

CASTER OF RED: WILLIAM "MAGNIFICENT BASTARD" SHAKESPEARE
Shakespeare: I have come to report!
Semiramis: Well? Out with it already.
Shakespeare: Berserker has begun marching towards Trifas!
This brought a mild surprise to both Shirou and Semiramis. The Caster continued with his theatrical mannerisms.
Shakespeare: Archer is in pursuit, yet I suspect her attempts will end in failure!
Shirou: ...You're the one who incited him, aren't you?
