Has Lois canonically liked anything in particular about Kryptonian culture? Like, has she engaged with it? I'm curious how much specifically Clark shares with her on that score.
I guess the closest answers are that the Earth-Two Lois had a second wedding ceremony with her Superman in the Kryptonian tradition after having had a human one with Clark, and this bit from PKJ and companies' Action Comics run:
Or, when the Rogues received their first and last names, in addition to the appearances of any aliases or writer mistakes.
Starting with the simplest:
Golden Glider:
She debuts as Lisa Snart in Flash vol. 1 #250 (1977), and keeps the name from then onwards. Despite probably being Cary Bates’ most-frequently-recurring original villain, he never forgot her name. Lisa Star was her stage name (as per Flash vol. 1 #151).
Abra Kadabra:
Abra Kadabra is actually, by all appearances, his real name, which means that he has had his full real name since his first appearance in Flash vol. 1 #128 (1962).
Dr. Alchemy II:
Alvin debuts in Flash vol. 1 #287-289. At the end of issue #287, he reveals himself to be Al Desmond, and in #288 he reveals that Al is short for Alvin.
Gorilla Grodd:
Grodd is named as such in his first appearance, Flash vol. 1 #106 (1959) and keeps the name from then on.
Rainbow Raider:
Rainbow Raider is named Roy G. Bivolo in his first appearance (Flash vol. 1 #286 from 1980) and keeps the name from then on. Cary Bates did not mess his name up at any point.
Weather Wizard:
Weather Wizard is named Mark Mardon in his first appearance, Flash vol. 1 #110 (1959).
This stays his name consistently until the New 52 in 2011, when his first name is changed to Marco to reflect his newly-added Guatemalan heritage.
Oddly, his last name is misspelled as Marden in Flash vol. 1 #145 (1964), but no one misremembers his name. Not even Cary Bates!
Captain Cold:
Captain Cold is named Len Snart in his very first appearance, Showcase #4 from 1957. Remarkably, Cary Bates never misremembered his name.
Leonard as the full first name seems to have been established in the 80-Page Flash Spectacular from 1978, and it does not seem to appear in the comic stories themselves until after Crisis.
Lisa nicknames him Lenny in Flash vol. 1 #314 (1982).
Trickster I:
Trickster is named James Jesse in his first appearance, Flash vol. 1 #113 (1960).
This name is revealed to be a stage name in Secret Files and Origins #41 from 1989; his true birth name is Giovanni Giuseppi (his family is, evidently, from Naples).
Curiously, James-Jesse-as-stage-name appears to have been retconned out in Rebirth, since when James returns in Flash #66 with a revised backstory, he and his family are treated as if Jesse is their real last name.
So James Jesse is sometimes an alias, and sometimes not.
Other notable aliases include Mr. Reynard (from Flash vol. 1 #152), Trixie (from Blue Devil #19), JJ from tax school (from Catwoman #69-71), Lechter Hannibal, and Father Gutierrez (bot from Impulse #14-15).
Heat Wave: Heat Wave debuted in Flash vol. 1 #140 (1963), but he had no name until Cary Bates finally named him Mick Rory in Flash vol. 1 #226 (1974). So Mick went almost 10 years with no name. Bates did, however, remember his name in every issue where he appeared.
Much later, in a Who's Who entry from the 1990s, Mark Waid inexplicably forgot his name and renamed him Rory Calhoun. This name appeared only once in Flash comics, in Flash vol. 2 #135 (which is a terrible Mick story all around anyway.) Then Johns took over the book and everyone remembered what his name actually was.
Mr. Element/Dr. Alchemy I:
Despite debuting in Showcase #13 (1958), Mr. Element/Dr. Alchemy wasn't named until Flash vol. 1 #147 (1964), when he was given the name Al Desmond.
Al was revealed to be short for Albert in Flash vol. 1 #287 (1980) by Cary Bates, who never misremembered his name.
The Top:
The Top was named Roscoe Dillon in his debut issue, Flash vol. 1 #122 (1961).
Cary Bates mistakenly renamed him Roscoe Neyle in Flash vol. 1 #219 (1973), but curiously always remembered the name correctly thereafter.
Neyle was retconned into his middle name in 1975, as evidenced by The Amazing World of DC Comics #8 referring to him with that full name, and by the More Secret Origins of Super-Villains Limited Collectors Edition book from 1976, which calls him Roscoe N. Dillon.
Captain Boomerang:
Captain Boomerang was introduced as Digger Harkness in his first appearance, Flash vol. 1 #117 (1960). In that same issue, he uses the name George Green as an alias.
Digger does not receive a proper first name until 1976, when the DC Calendar and the More Secret Origins of Super-Villains Limited Collectors Edition book revealed that his first name was indeed George. Curiously, no one uses this first name in the comics proper until Post-Crisis---the narration just calls him Digger.
In Flash vol. 1 #227 (1974), Bates may have misremembered Digger’s actual last name, because he called his father Aussie Green...even though Green was the alias Digger used rather than his actual last name (Harkness).
Pied Piper: Despite debuting in Flash vol. 1 #106, Pied Piper went over a decade with no real name.
In 1976, he finally is provided with the name Thomas Peterson...in the More Secret Origins of Super-Villains Limited Collectors Edition book. (Later this was revealed to be an alias.)
Cary Bates provided him with a second alias, Henry Darrow, and his true name, Hartley Rathaway, in Flash vol. 1 #307 (1982).
Then Cary Bates confused himself repeatedly in the Trial of the Flash storyline.
In Flash #337 (1984), Digger calls Piper Thomas Peterson, so either Piper told the Rogues fake names, or Bates messed up. Then in issue #338, Sam calls Piper Henry, and Digger is not confused. Later in the issue, Digger correctly calls him Rathaway. Finally, in Flash vol. 1 #346 (1985), Piper is incorrectly called Henry Rathaway.
Bates maybe should have reconsidered all those aliases, because it seems to have confused him.
Professor Zoom the Reverse-Flash:
Reverse-Flash is introduced as Eobard Thawne in his first appearance in Flash vol. 1 #139 (1963).
In Flash vol. 1 #225, Bates misspelled his last name as Thawnye.
Then in Flash vol. 1 #283 (1979), Bates seems to have forgotten that Reverse-Flash had a name, and calls him Professor Adrian Zoom (this error also appears in issue #300).
Flash vol. 1 #334 (1984) gives us Eobard Thwayne.
Flash vol. 1 #342 (1984) provides us with Eobard Thayne.
Flash vol. 1 #350 (1985) has Eobard Thine.
So Bates misremembered his name twice and misspelled his last name incorrectly four different times in four different ways.
Mirror Master i:
Mirror Master was introduced as Scudder in Flash vol. 1 #105 (1959), and then went over a decade without a first name.
In Flash vol. 1 #219 (1973), Cary Bates named him Joe Scudder.
Then, in 1975, The Amazing World of DC Comics #8 called him Sam Scudder.
In 1976, the DC calendar for that year called him Sam Scudder, as did the More Secret Origins of Super-Villains Limited Collectors Edition book. Bates also called him Sam in Flash #239 and #243 in that same year.
In Flash vol. 1 #255 (1977), Sam was called Samuel Joseph Scudder for the first time, and was also called Sam in Flash vol. 1 #256.
Justice League #158 (1978) and the 80-Page Flash Spectacular from 1978 call him Sam Scudder and Samuel Joseph Scudder, respectively.
Flash vol. 1 #277 (1979) calls him Sam Scudder. The Super Friends #24 from the same year calls him Samuel Joseph Scudder.
Then in Flash #292 (1980) Bates calls him Joe Scudder once more.
Flash #300 (1980) and #306 (1981) have him back as Sam.
Flash #320 (1982) sees Cary Bates call him Joe once more.
In issue #338 (1984), Bates calls him Joe yet again.
And from #347 onward (1985), Bates finally remembers that his name is supposed to be Sam.
But after the Flash run ended in Flash #350 (1985), Mirror Master made an appearance in Batman #368 and Detective Comics #555, where he was called Joe Scudder one last time before he died in Crisis on Infinite Earths.
Mirror Master II:
The second Mirror Master is introduced in Animal Man #8 (1989) as McCulloch, with no first name.
In 1998, Impulse #41 (1998) called him Angus McCulloch.
Flash Secret Files and Origins #3 (2001) gave him the name Evan McCulloch, which he has used ever since.
