This is the problem with that "everything is canon" thing. Continuity does actually matter, and Vril being on Colu in that story simply doesn't jive with, well, fuckin' anything.
The only way he could be considered such a dangerous avatar of entropy is if he already had a large influence and reputation, which means L.E.G.I.O.N would have to exist. Except in No Justice, he had been lock up on Colu all his life, and at the end, he fucks off to go form L.E.G.I.O.N. Furthermore, in that one GL issue(?) cameo, the gang's all there, but since Invasion! maybe kinda sorta didn't happen in Nu52/Rebirth, how did he meet all his commanders?
It's just such a blatant copout of any responsibility for editorial to do an important part of their jobs. It cannot be SO hard to have some meetings to decide a timeline of events. What happened and when. Useless bastards.
