DC/Marvel merged timeline


This is an unfinished timeline I developed for my combined Marvel-DC campaign. Since my players are mostly “beer and pretzels” types who don’t really care about such trivia, I never got around to finishing it.

Besides the “amalgam”  aspect, the main conceit is that all the heroes aged in real time from the date of their first appearance. Which means most of them are conveniently dead or retired by the time the PCs come along. Feel free to suggest additions or alternatives…

This article is one of the various campaign timelines on writeups.org.
