I call him ultimate Shirou because he's several versions of Shirou sort of smushed together, not because of any power reason.
Chimera Shirou.
By the way, I think I have mentioned it before, but on the thread premise I have a bit of rogue head canon
i have a pet theory that when saber’s age was frozen, she was just hitting a growth spurt. This is the primary reason for a couple of saber’s more notable traits. See if I’m right her metabolism is super charged to prepare for growing up a bit more, lending itself well for saber’s rocket propelled high energy fighting methods using Prana burst
...however, you ever met a kid in a growth spurt? They are always hungry.
I figure she just likes eating because Shirou's cooking is so good, not just in general (Grand Order jokes notwithstanding). Does Zero have any reference to her appetite?
The most canon of all TM works, Carnival Phantasm, has her as a glutton even if it isn't Shirou's food
you must accept this hard truth
Oh she definitely is, there is no doubt about that. She is a reasonably intelligent 35 year old woman who spent 20 years in the body of a hyperactive teenager. Learning to enjoy food that satisfies both a high calorie need as well as stimulates the senses would make sense as a hobby
Hungry Hungry Heroic Spirits game when
Maybe twenty years of being forced to be an adult also a king, make her wants to be a teenager again when she had a second chance at life.
Well the Fate route is all about getting her to chill out and actually be human for once in her life instead of y’know.
Probably. But not without enough prodding and interactions with Shirou.
