Does Gilgamesh in FGO Remember Fate/strange Fake? The Truth Behind 'Sha Naqba Imuru'

It’s a question that plagues every Fate/Grand Order player who picks up the Fate/strange Fake light novels: "Why does this Gilgamesh feel different?"

In FGO, Archer Gilgamesh is often... difficult. Arrogant, dismissive, and prone to calling you a "mongrel." But in Strange Fake, he feels sharper, more serious, and strangely—more "human."

Is this a retcon? Or does the King of Heroes actually remember what happened in Snowfield?

The answer lies in his often-forgotten Noble Phantasm: Sha Naqba Imuru.

The "Omniscient Star" Paradox

Sha Naqba Imuru (The Omniscient Star) is Gilgamesh's innate ability to see the "truth" of the world. It’s essentially high-level clairvoyance that allows him to discern true names, Noble Phantasms, and even glimpses of parallel futures/pasts.

So, does he remember? Technically, yes.

The Throne of Heroes exists outside of time. While a standard Servant summons usually resets memories to prevent information overload, Gilgamesh is an exception. His clairvoyance allows him to peer into the records of his other summonings.

He knows about the events of Fate/strange Fake. He knows about the Fake Holy Grail War.

Why He Acts Differently

If he knows everything, why act like a jerk in FGO?

1. Enkidu Factor: In Strange Fake, Gilgamesh senses Enkidu's presence immediately. This shifts his mood from "Bored King" to "Rivals Reunited." In FGO (unless you have Enkidu), he reverts to his default state of boredom.
2. Self-Nerfing: Gilgamesh intentionally suppresses Sha Naqba Imuru most of the time. Why? Because knowing the ending of every story is boring. He prefers to be surprised. He only fully activates it when he gets serious (like in Babylonia or Strange Fake).

Conclusion: He Chooses to Forget

Distinguishing the "versions" of Gilgamesh is key to understanding the Nasuverse.

The Gilgamesh in your Chaldea isn't ignorant of Strange Fake; he just doesn't care—unless you give him a reason to. He is a King who has seen everything, done everything, and ruled everything.

The only thing that truly wakes him up is a challenge worthy of his oldest friend.
