I used to be into comics in the late 80's early 90's. For some reason I got interested in them again a couple years ago. I was mostly into Batman,
X-Men and Spiderman.
I found some sites to download entire collections from and got hooked. I have over a terabyte of comics downloaded now. So many I didn't even know
where to start or how to organize them.
I figured Batman was probably my all time favorite so I would start there. I have learned a lot about the DC timeline because of this. I haven't
really even started messing with all my Marvel titles yet.
Anyway, I can tell you a basic timeline of the DC "resets". Basically comic writers originally had no agreed upon concept of continuity so different
titles featuring the same character could have conflicting scenarios.
They explained these away by having there be an infinite amount of other Earths that all were just slightly different. There might be an Earth that
Superman's rocket from Krypton landed in the USSR instead in the USA, or maybe one where Nelson Mandela died in prison in '93.
In 1985 they decided to rectify this by having a major crisis and destroy all other Earths except Earth Prime or Earth 1 or whatever they called the
main one. They called this major crossover event Crisis on Infinite Earths.
Some titles reset their count by changing volumes (Flash v2 #1), while others just had a soft reset by giving the character a new origin point (Batman
v1 #404 - Year One) to rewrite different aspects and maintain continuity.
Things were cool and all for awhile but you know, a lot of comics and a lot of writers so things were still not where they wanted them.
They had another crisis event in 1994 called Zero Hour: A Crisis in Time. This one had Green Lantern trying to destroy and remake the universe after
he became some really powerful bad guy (Parallax). Every monthly title skipped a month (Oct?) and had an issue #0 instead.
Life went on and everything was rainbows and unicorns until about 2005. They decided to have another major crisis called Infinite Crisis. This was a
sequel to the original, Crisis on Infinite Earths, and revisited alternate Earths.
Throughout the end of Infinite Crisis and the following year were more major story arcs and tie-ins leading up to Final Crisis in 2008.
Believe it or not, this would not be the DC Universe's final crisis. More catastrophes were averted and humanity was preserved until 2011 when
Flashpoint is a tale about the dos and don'ts of time travel and it messes things up pretty good in DC world. The fallout is that EVERY title is
canceled and they restart with 52 titles renamed as the New 52 (about half of them core titles and the other half kinda random stuff and remakes).
That takes you up to whatever is currently going on I guess. This post turned out to be a lot longer than I wanted it to haha!
I don't even really know if this is what you were asking for but I just had been reading about all this stuff and figured I would drop some comic
knowledge off on my way through
Have a great night, peace!
