So this one is pretty much all /u/Warlach, because I get the feeling not many other people have this level of minutiae off hand.

When did Woodrue switch from Plant Master to “The Flouronic Man,” and when did Professor Zoom’s alias switch from Adrian Zoom to Eobard Thawne? I’m rereading an old “greatest stories ever told” trade and the naming threw me off.

Eobard Thawne and Floronic Man together!

Thanks, I think :P

What was actually changed from golden age to silver age? I know things like Kal-L to Kal-El happened, but what else was actually changed?

Hey hey, this seems like my kinda question. For these purposes, and because it’s this sub, I’ll stick to what happened with DC during this time ;)
