Steel

A stalwart presence in the Modern Age, Steel made their debut in 2001's JLA: Heaven's Ladder, brought to life by the formidable creative team of Mark Waid, Christian Heiss, and Bryan Hitch. Published under Panini Deutschland, this character has kept extraordinary company across their appearances — sharing pages with titans like Superman, Wonder Woman, Green Lantern, and John Henry Irons. With a footprint stretching across more than two decades and appearances in landmark publications including Superman Special: Action Comics 1000, Steel is a figure whose place in the Modern Age tapestry is well worth exploring for any dedicated collector.
