Earth 4 Superman was beyond conflict all together. Not only was Ultraman being casually subdued by E4 Supes(with one hand), but his attacks were entirely ineffectual to boot: (please log in to view the image)
This is the same Ultraman who lifted infinity in the very same series.
Galan's probably right, but we run the risk of applying a no-limit fallacy.
I mean, GA Prime did some really stupid shit, like punching into the 5th dimension with enough precision to pull out Mxy. Ultraman's HV may not have hurt Allan, but HV is not really comparable to busting through two dimensions with a single punch.
