Assuming we're ignoring battle powers, we'd have to go via-scaling from the energy of their destructive capability. 10% Daimao is still going to end up at Town level via-scaling from his Old full power still being at least Small City level via-scaling from Manly GAINZ Roshi in the first arc, so he still oneshots Taopaipai along with all of the 22nd TB while he's at it.
