The Guardian

Few characters carry a name as iconic as The Guardian, and this DC hero's Bronze Age arrival in Superman's Pal, Jimmy Olsen #136 in 1971 dropped them straight into the deep end of the DC Universe. Over a remarkable span stretching nearly five decades to 2019, The Guardian carved out a presence across the Superman family of titles — Superman, Adventures of Superman, and the Jimmy Olsen series — rubbing shoulders with some of the most legendary figures in comics: Superman, Batman, Green Lantern, and The Flash. With 35 catalog appearances and two recognized key issues to their name, this is a character whose longevity speaks for itself, a durable piece of DC's tapestry well worth tracking down for any serious Bronze Age collector.
