Batman: Fortress #6

In "Fortress [Part 6]," Batman dives deep beneath the ocean’s surface to reach the long-lost Fortress of Solitude, leading a tense alliance of Aqualad, Red Arrow, D'ayl, and Lex Luthor in a high-stakes mission to unlock its secrets. With the fate of Earth hanging in the balance, the team must navigate the submerged ruins of Superman’s sanctuary to find a weapon capable of facing an overwhelming alien threat. Written by Gary Whitta and brought to life with bold, dynamic art by Darick Robertson—both interior and cover—this issue pushes Batman’s resolve to the limit in a story that’s as relentless as it is mysterious.
