The Best of DC #64

Dynamo Boy finds himself cast out into the future by the Legion of Super-Villains—Lightning Lord, Cosmic King, and Saturn Queen—only to awaken in a time where the heroes he once stood with have grown distant. The Legion of Super-Heroes, now scattered across time and space, takes notice and answers the LSV’s challenge with a final showdown that could change everything.

In the vast silence of space, the Legion of Super-Heroes faces a terrifying anomaly: the Super-Moby Dick of Space, a colossal creature that leaves destruction in its wake. When Lightning Lad loses an arm to the beast and Ultra Boy’s efforts falter, the team must rally under his leadership to confront the unknown threat — with Dr. Lanphier’s insights and the full might of the Legion’s combined strength.

In "Part I: The War between Krypton and Earth!", the Legion of Super-Heroes splits to investigate an ancient artifact tied to a forgotten conflict. While one group follows Kryptonians fleeing their rigid, anti-scientific world to settle on Earth, another discovers alien colonists in ancient Atlantis—unearthing a mystery that spans two worlds and two timelines.

In the aftermath of a fractured alliance, the Legion of Super-Heroes grapples with the growing rift between Atlanteans and Kryptonians, as tensions boil over in a civil war that threatens their shared future. With Brainiac 5 uncovering the truth behind Earth’s air and its effects on Atlanteans, the team races to find a way to bridge the divide—while Superboy uncovers new clues about the fate of the Kryptonians, deepening the mystery.

In the aftermath of a high-stakes case, Superboy uncovers a startling truth: the mysterious Unknown Boy is actually Supergirl in disguise. As the Legion grapples with the revelation, Supergirl begins to piece together fragmented memories of a red kryptonite storm that erased her past—yet she still remembers the need to hide, and the reason she created the Unknown Boy persona.
