Question about Comicbook Crossovers

[LordGriffin1000]

So I just started reading comics (Marvel and DC) and I know we don't use feats from crossovers between the two but what about crossovers with characters from the same franchise like if Batman crossed with Superman, can feats from that be taken?.

If events from canon story lines are mentioned does that allow feats to be used even if it's from a crossover involving DC or Marvel even if they have characters from different franchises.

Example: I just recently read a crossover between Green Lantern and the Aliens from Aliens. In the crossover it said Hal confronted the Aliens in one of his flights and he moved them to Mogo the Living Planet. Now a decade later Kyle Rayner deals with them and it's mentioned he's the last green lantern after the rest got killed by Hal/Parallax (which is an actual story line in DC)

Would this be counted as Canon or more like a spin-off or a What if type deal?.

I think that we have to consider the Aliens example as a non-canon "What If?" scenario.

However, if Batman meets with Superman, we can obviously use that, unless it is an Elseworlds book.

Alright thanks for the info but what's an Elseworlds Book if I may ask?.

 

[Antvasima]

It is what DC Comics call an out of continuity story.
