Action Comics #883

In "Divine Spark Part 1," Jax-Ur's sinister experiments unfold in the hidden land of Ur, where captured students become test subjects, while back on Earth, Nightwing and Flamebird race to contain the fractured Brimstone threat in Toronto. As Jimmy Olsen’s disappearance deepens, Perry White uncovers a hidden clue in his apartment, leading to a mysterious connection between Dr. Pillings’ lab, the split Brimstone, and the enigmatic Flamebird. With Chris struggling under a new wave of aging and Thara torn between loyalty and love, the truth behind the Kryptonian sleeper agents begins to surface—just as Dr. Pilling’s secret lab reveals a far deeper conspiracy.

In "Chapter Five" from Action Comics #883, Captain Atom faces off against Major Force on Mirabai’s world, their clash echoing past betrayals as Major Force mocks Atom’s history as Monarch—only for Atom to insist he’s no longer that man. While Jenny Blake slips away to maintain her cover, Major Force drags Atom to Metropolis, where a swarm of forces prepares to arrest him—until Mon-El arrives and turns the tide.
