Can someone point me where to start? Keep getting convulted answers in different sources.
In terms of early appearances, he had extended runs in All-American Comics and with the JSA in All-Star Comics. Unfortunately, digitization is really spotty for Golden Age books, so you might not be able to find those.
His subsequent appearances were in the JLA/JSA crossovers from Justice League of America (1960-). There were a ton of those, though as far as I know Doctor Mid-Nite himself didn’t do all that much in them.
Looking at a list of his appearances (which should be taken with a grain of salt; I suspect most of those are brief flashbacks), it seems like he appeared a lot in All-Star Squadron and apparently in Infinity Inc. (presumably in connection with Beth Chapel, since McNider wasn’t a member of II).
Not sure what he was doing in the early '90s, but he died in Zero Hour in '94 and has been dead since. A few stories in Starman and various JSA titles have referred back to him, but Pieter Cross has been the main Doctor Mid-Nite since 1999.
Anything good with cross?
Some of these are the Peter Cross version.
Well, yeah. My first post was about Charles McNider, and then he asked about Pieter Cross.
Cross is my favorite I was reading JSA when it first came out and I remember how cool it was when he showed up during the Obsidian 3-parter and joined the team.
I will check these all out, thanks everyone.
