So, in terms of the continuity thing, how strict do we have to be with it?
Let me explain: I hadn't, until just now, read the recent Dark Avengers or latter end of Thunderbolts, where Man-Thing is featured as part of the team. In it, they don't just alter some things about his powers or abilities, but in fact, radically redefine how the character works. Prior to this change, he was a mindless monster who could only react to the emotions of others, but now he has the mind of some ancient god or some such within him.
The big issue is, the story I want to write also includes the new Hobgoblin and recent historical events in Haiti. While the Hobgoblin thing would be possible to work around, the Haitian thing wouldn't, so I can't just set the story in the past.
In this case, if I want to use Man-Thing, do I have to use this new version, or can I use the version that existed for 30+ years? I totally understand if not, it really doesn't make sense to pull characters from different time streams for no reason, just a fairly major setback to what I thought was going to be a good story.
