Baron Death (World War II Nazi foreign agent)

First (and only?) appearance: Steel, the Indestructible Man #1
(cover-dated March 1978, but on-sale date of December 20, 1977 per the GCD)



There was one page(!) where we first saw Baron Death reaching the U.S. shores


Then there were several pages where Steel fought with agents working with Baron Death






but as far as I am aware, that was it for Baron Death.
(There were four additional issues of Steel, the Indestructible Man published before the title fell victim to the "DC Implosion", but it dos not seem Baron Death made any return appearance in those four issues.)
