Mighty Metal Men - Silver and Tin

On the trail of invading Metal Men from Jupiter, or at least a planet thought to be Jupiter (we last saw that world in Starman's hyperspace voyage yesterday) by a concerned scientist, Earth-Two's Hawkman is the first to encounter his prey, Silver!

Each of these metal men consume various metals and adopt the attributes of said metal. Using pennys to fuse their atomic structure, this regimen of robots was knocked out.

Tin of Earth-One's Metal Men had always been a good natured teammate if a bit beholden to a massive inferiority complex given that he was a lesser renowned element. On one occasion, he exhibited tyranical disposition when an alien race made him their king and fed him a diet that turned him massive and evil. He soon recovered and rejoined his mates.

And over time, when each Tin was destroyed a replica was constructed in his place. Feeling the need for companionship, he eventually constructed a "girlfriend" known only as Nameless who had a tragic end despite their mutual feelings for one another.
