Tbh I haven't kept up with John's story so I only took what I grasped from this issue fast reading it at work:could you explain the main bits to me from this Chapter
John straight up claims to have fused (either eaten by or ate, it seems to make no difference) with an Universal Entity (explictly stated to have destroyed the Universe if John didn't absorb it).
So John now has a Universal amp form like Hal and Kyle. Neat, now for Kilowog's
Another Guardian fuck up with an entity trying to fuck with John's new power, gets possessed and amped by it requiring Hal and the Justice League's intervention (and considering it looks like Hal brought Barry and John, Hal aint fucking around)
