Poison Ivy

Few characters announce themselves quite like Poison Ivy, who made her catalog debut in Mad Presents Batman #1 (2012) — a Modern Age entry brought to life by the legendary creative pairing of Stan Hart and Mort Drucker. Across a run stretching into 2025, she turns up in some genuinely prestigious company, sharing pages with Batman, Bruce Wayne, Bane, the Penguin, and Jervis Tetch in titles as celebrated as Tom King's acclaimed Batman run and its Rebirth Deluxe Edition collections. With only seven appearances in this catalog, she's a selective presence rather than a ubiquitous one — which, if anything, makes each of those issues feel like a find worth tracking down.
