Earlier identity: Kyle Rayner's Ion stories
Separate entity revealed: Green Lantern: Sinestro Corps Special #1 (2007)
Spoiler boundary: this profile explains the Ion revelation and change of host in Sinestro Corps War.
Kyle's identity and the separate being
“Ion” first belongs to Kyle Rayner's story as a greatly empowered hero. His early-2000s transformation and the later Ion: Guardian of the Universe series should be distinguished from the revelation of a separate creature. An early Kyle-as-Ion issue is not the debut of the whale-like entity as readers now know it.
The 2006 series follows Kyle after Infinite Crisis and the Rann/Thanagar War Special. DC's issue #1 listing credits Ron Marz and Greg Tocchini and frames Kyle's transformed abilities as a mystery. The 2007 Sinestro Corps Special makes the host/entity distinction explicit as the crossover develops.
Where Ion fits in the spectrum
Ion is the living avatar of green willpower, paired with the green light just as Parallax embodies yellow fear. DC's official history timeline identifies both among the spectrum's avatars.
Keep three things separate: the entity, the Central Power Battery that supplies the Corps, and the individual ring that focuses a Lantern's power. An ordinary Green Lantern is not automatically an Ion host. Hosting the entity is a particular story development, not a rank every strong Lantern earns.
Spoilers — host changes in Sinestro Corps War and Emerald Eclipse
Sinestro Corps War turns Ion's host into a strategic question. With Kyle possessed by Parallax, another Lantern takes up the mantle: the Daxamite Sodam Yat. Tales of the Sinestro Corps Presents: Ion #1 explores that transition and Kyle's place afterward.
Sodam's later story brings the power back to a personal obligation. In Emerald Eclipse, Mongul has seized Daxam, the homeworld Sodam had vowed not to revisit. Being Ion does not remove that conflict; it raises the stakes of his decision to return.
