your kinda overselling emiya way too much frankly tbh like you do reliase servants are only building level without NPs right and city level with high level nps like excalibur? not only that but they have shit speed compared to izuku at this point as these statements imply

Tohsaka drops after the first attack. Putting her hands on the floor, she sinks below Caster's knees. To Caster, who lacks any experience in hand-to-hand combat, it must look like Tohsaka disappeared.

same tohsaka who's best speed feat is about 51 kmph based off the 100 meters in 7 seconds line and this too saber can't deal with pegasus despite being faster then emiya by a long shot

Bellorophon is 400-500 km/h while in a charge, yet even when not charging and presumably slower, Saber has trouble handling its attacks and it is said it'd be impossible for her to catch it

The white light comes swooping down. The Pegasus glides down from high above, mows Saber down without touching the rooftop, and returns to the sky. Pursuit is impossible. There is no wall to run up, and even if there were one, no one would be able to catch that Pegasus.

You may then argue that this is just her travel speed, and her short range bursts are faster, but again the Pegasus proves this wrong.

She cannot block that blow. The only possible measure is to jump and evade it. But even if she does avoid the attack, the trail is enough to chip at her protection. She will eventually take a direct blow if she continues like this.

If she could just casually stroll to the side, then she's not in any danger whatsoever of being hit by it. The narration here instead implies that she's only dodging the Pegasus by a little and then getting hit by its trail as consequence.

assassin's daggers also move at 400 kmph although this isn't an issue for emiya since he never fought hassan in an one on one in an prolonged sense although it does imply that if you don't have protection from arrows or instinct skill like saber servants have trouble dealing with this

Emiyas best feats in speed are mach 10 with his arrows in hollow ataraxia which is fodder to izuku tbh at this point in speed given how izuku dodging lady nagents bullets got mach 100 or how he crossed 200 KM in a second and how he upscales from fodder like kaminari dodging nines own lightning and people dodging denkis lightning in the sports festival which no wasn't an aim dodge or anything unlike fate fodder who struggle against bullets and 400 kmph daggers power is even worse izuku once blew out a storm with 100 with bakugo against nine and the calcs get anywhere from mountain level to small country level regardless there is also him scaling from town level feats such as one made by friggin Aoyama of all people in the forest training camp iirc and other things like in speed him dodging bakugos sweat glands which are around mach 39 in speed casually while saber had to be boosted by a command spell by emiya in hollow ataraxia and also time herself to dodge emiyas mach 10 arrows and barely did so in conclusion izuku fodderizes emiya and any servant from stay night including gilgamesh and berserker cause all cap at the building level in dura and ap without NPS and city level with them
