Yes, I know. I've read the story. And a later comic, I do believe by the same writers(could be wrong), had Superman face them again but now that he knew how Psi-Phon worked he resisted the telepathy. You argued how Cap fared against Dreadnaught duplicating Superman, my point was because a later fight Superman was clearly superior to Dreadnaught duplicating his powers, I don't think Dreadnaught is actually equal to who he duplicates(skill and experience aside). And Superman was fairly casual in the beat down. It was ONLY Superman that Dreadnaught duplicated in the later comic, and Superman had no force field nor was in his Clark identity.
I know what issue you're referring to (Adventures of Superman #469), but there was no context that indicated Dreadnaught duplicated Superman's powers again.
I didn't see any mention of it.
