Marsboy - "The Boy from Mars!" SUPERBOY #14 (May-Jun 1951)

    Sutri of Mars, a lad who has powers similar to Superboy's, gained his abilities by witnessing a strange metoer fall from the sky (his x-ray vision cannot penetrate copper instead of lead). Lana Lang blackmails him into pretending to be her boyfriend in order to make Superboy jealous. A martian girl named Cyntherea helps turn the tables on Lana and they leave Marsboy to resume his heroic deeds. He also appeared in SUPERBOY #16 (Sep-Oct 1951) & ADVENTURE COMICS #195 (Dec 1953).
