So I have just read few things here and there. Flash at latest chapter, some Multiversity, Future's End at lastest chapter, Captain Atom, Superman almost at the latest chapter, Justice League at the latest chapter and some more.

I would like to know few things about how things are right now.

1. Why Superman hates Batman in Future's End, is there a comic that talks what happened between them?

2. What Darkseid War are people talking about in Future's End? 50% of the comic they spend talking about when Parademons attacked the world.

3. How does Future's End, Convergence and Multiversity go together? Should I read Multiversity or it has no place in the main story.

4. Is Future's End canon? Is Multiversity Canon?

I was away from the comics too long and it's really hard to understand what the hell is going on. Future's End has been good so far.

Multiversity is canon.

I'm not sure why Batman hates Superman in Futures end, and to my knowledge it has not been revealed in any comics

Futures end is a potential future of the dc universe

I'm not completely sure what's happening with convergence, but as far as I can tell it is the aftermath of Futures End and Earth 2 Worlds End, I'm not sure how or whether multiversity ties in as I'm not reading it

So does any of that tie into the DC 52 main universe or story or how ever you call it or is it just all a nice non canon storylines.

@sirneko: Umm I think they are part of the new 52 universe but not sure whether they are canon
