I'm no authority on Kyle Rayner. The stuff I read about him mostly include some larger DC crossovers, some early GL stuff and the stuff from rebirth - today. And from what I've managed to gather, without much help from you guys (uhuh) is that when Kyle has the fancy chest symbol, he is Ion. I know, it's awfully simple, and could be wrong, but hear me out.

That chest thing is where Ion lives! After Rann Thanagar War, Kyle was definitely Ion. And that happened around what time period? Same time as Green Lantern v3 150? Could someone please clarify which of the Kyle Rayners possess the Ion power, and those who do not? I've scoured through Id's respect thread and some of "current green lantern kyle" feats seem to be the same guy as Ion.
