Metallo

Few villains in the DC Universe carry the kind of iconic weight that Metallo does, and this catalog entry — debuting in the landmark Who's Who: The Definitive Directory of the DC Universe #15 in 1986 — captures him at the dawn of the Copper Age, when DC was busily codifying its rich mythology for a new generation of readers. Across roughly three decades of appearances, he's kept dangerous company indeed, sharing pages with the likes of Superman, Batman, Bruce Wayne, and even Darkseid. Whether turning up in Adventures of Superman or the retro-flavored Wonder Woman '77, Metallo is a cornerstone DC figure well worth tracking down for any serious collector of the Man of Steel's rogues' gallery.
