Dolphin

A mysterious young woman with the ability to breathe underwater and survive the ocean depths, Dolphin's true origins and name remained largely unknown. She first surfaced during the multiverse-shaking Crisis on Infinite Earths, an enigmatic aquatic figure with an unclear past.

Dolphin made her debut in one of the most landmark events in DC history — Marv Wolfman and George Pérez's Crisis on Infinite Earths #4 in 1985, a Bronze Age entrance that couldn't have been more dramatic. Over the following three-plus decades she carved out a quiet but enduring niche in the DC Universe, appearing across Aquaman, The Titans, and even earning a place in Who's Who: The Definitive Directory of the DC Universe — the kind of recognition reserved for characters who genuinely matter to the mythology. Three of her appearances carry key-issue status, and the company she keeps — Donna Troy, Dick Grayson, Garth, and Nightwing among them — speaks to how deeply woven she is into the fabric of DC's aquatic and heroic corners. For collectors who love discovering figures with real history and genuine staying power, Dolphin is exactly the kind of gem worth tracking down.
