"Hordes Of The Immortal Emperor" is from Wonder Comics #16. I've posted stories from this issue before in Pappy's #158 and Pappy's #166.
Someone needs to collect all of the Wonderman stories. We're seeing part of a longer continuity, and what a continuity! A city, Pyropolis, on the sun! A villain named Dr. Voodoo! An "immortal emperor" (page 3) who looks like a smiley face caught in a vise! This is pretty crazy stuff, very entertaining.
The Grand Comics Database has mistakenly listed the contents of this issue, #16, under #15. It also lists the artist of Wonderman as Bob Oksner. See if you agree. Compare the story to this, also from 1948, from Sensation Comics, posted recently in Pappy's #254. Whether or not Oksner drew Wonderman--and I don't think he did--it doesn't detract from it being a screwball comic classic.
