The following characters are Superman canon, owned by DC Comics and/or Warner Brothers. Some are from the Reeve/Kidder Superman films, some are from Superman Returns, and some are from the monstrous collection of Superman comics that Lois owns.
Lex Luthor(and yes, I know these seven are a big fat DUH)
Jason (White in SR, but Lane for LS)
Police Commissioner Bill Henderson
Maggie Sawyer of the Metropolis SCU
Tobie Raines (and yes, I know now, having actually BOUGHT the miniseries comic, that I've been misspelling the character's name. Blame wikipedia. Oh, and while you're at it, if you've been wondering why a reporter like Tobie is living with Lt. Sawyer, go wikisearch Maggie Sawyer.)
Loueen (who's also misspelled; she's credited as Leueen, but I loathed that spelling and it wouldn't stick in my brain)
Gil and Judy
Steve "Grizzly" Lombard
I think that's all. One of our brilliant readers will surely inform us if we've screwed up.
Now, characters who are ours. This'll be a longer list, because we invented a lot of characters. Especially in about chapters 17 through 25, when we were handing out walk-on roles to all our pals. In those cases where the character is a clear tribute to one of our readers, reviewers, or friends, it should be obvious.
Kala Lane (OURS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Rhea (writer of the Eclectic Reader column)
Vanna of Vgerland Real Estate
Mel (the horse-fancying Texan who rescued Kitty. Hello, Mel!)
Dr. Shelby Patterson
Mankiewicz, Daily Star photographer
General Joffrey Unsworth
Officers Smith and Davis (not named for anyone, Smith was just a jerk and Smith's a common name. Sorry, Brian. Notice that Beateau above, if pronounced in French, sounds like Beeto.)
Babette from Accounting
Gwen (the obnoxious nurse)
Barbara Thomas and family
Vera (the obnoxious secretary)
Michelle Troupe, Ron & Lucy's fourth child (we also named Little Sam, Nora, and Joanna, but STM proved their existence)
Wade Carmichael and family (you will see his younger siblings later in LS and in Intimidation. Plus, Wade himself will be back very soon.)
The Smallville Geezers Convention (who are all, in some way, named after the quintessential old fart, my dad. Except Ellzey, who's named after my awesome boss, a self-described old guy)
GAZEERA!!!! (Yes, we know it's spelled Gojira, but Kala named the lizard)
Captain Jack the Ferret
Barkley the Beagle and his untold descendants, including Bagel
There's lots more we're forgetting, but it's 4:30 AM. And if any of our regulars have been left out, fear not, you shall appear. Particularly Kat (you got a restaurant named for you, but not a character yet), Lea (wanna be the hot blonde Richard dated in college? Hmm?), and 7crazyread, whose real name I don't know (that makes naming a character for you pretty hard). We also need to get laramary in there, too.
