Teen Titans #18

The tagline says it all — "Robin Today, Batman Tomorrow" — and Mike McKone and Marlo Alquiza's cover delivers on that promise with a striking graveyard tableau: a battle-ready Batman crouches atop a stone cross above a tombstone reading "Here Lies Bruce Wayne, Beloved Husband," while Robin faces him from below, fists raised, with Alfred Pennyworth's grave visible nearby. It's a genuinely unsettling generational confrontation that sets the tone for part two of the "Titans Tomorrow" arc, written by Geoff Johns. This 2005 DC issue uses its cover real estate boldly, teasing a future both thrilling and deeply ominous.
