@Damage3245: Endeavor is weaker than Shigaraki, and was bleeding from the head with one punch. He should probably downscale to Baseline High 7-A.
Crust's AP would be baseline too, since he didn't cause major damage. And was only able to cut off a limb when the Nomu was already decaying.
USJ Nomu, USJ All Might, Shigaraki, High-Ends, Star and Stripe's Enhanced Strength, and Mirko's AP/Dura with Rabbit, are all scaling to 2.65 Gigatons.
Kamino All Might is stronger than Endeavor so he upscales from him, but is weaker than Shigaraki, who is equal to USJ All Might. BoS 100% Deku and Muscular are around the same level as Kamino All Might, maybe slightly stronger but not by any noticeable amount.
Nejire gets a possibly baseline High 7-A rating for maybe injuring a Near High-End.
45% Izuku is baseline High 7-A or 1 GT as well, since he was able to take a hit from Shigaraki but he was coughing up blood.
Nagant scales to 45% Izuku, she can injure him with her bullets and by jabbing her rifle into his stomach.
Um... I'm having a hard time with this. I think my brain isn't in this today, I'm getting a headache. I'll check back tomorrow, I don't think I'm well right now.
