mainverse: green of all hues.
this is the default mainverse of this blog, where kyle has given away the power of the life equation to make the white lantern corps, but hasn't lost the white ring. instead, since the white lanterns are meant to be active only in case of emergencies, he returns to his origins and wields the green ring once more.
it's his "current" timeline.
unless otherwise tagged, you can assume this is where interactions are happening.
self-explanatory! that is when he has both the life equation embedded in his soul and the mastery over the seven passions. can also go with omega lantern continuity. timeline-wise, it goes from new guardians to midway into hal jordan and the green lantern corps (a bit after godhead).
this is basically any verse that has to do with the version of ion he becomes in ion: the guardian of the universe. less powerful as a god but perhaps the most frightening version of a green lantern, given how he is host to the willpower entity itself.
verse: last green on earth.
events between emerald twilight and the reinstating of the green lantern corps go here. basically, this goes for anything that has kyle be a fresh-faced rookie and the "only" ringbearer on earth.
ion the first was his closest iteration to being a proper deity; omnipotent and omniscient, his status as such was brief but given he could manipulate time, it's possible to use him at any given point since time was not a constraint that applies to him.
verse: a self fulfilling prophecy.
this isn't exactly a verse as much as it is oblivion's tag. for those unfamiliar, oblivion is a construct entity made out of kyle's worst feelings and traumas that he subconsciously tried to expunge from himself while under duress on his early days as green lantern. he feeds on kyle's life force and is as strong as he is, as well as not exactly a "living" creature, therefore remaining mostly unkillable. during his brief tenure in circle of fire, oblivion singlehandedly defeated the justice league given his nature as an entity rather than a person, so caution is always advised when facing him.
the only known way to defeat him is to either absorb all of his energy (which may prove taxing, given how negative his energy is) or have kyle reabsorb the creature himself.
