|The Drunken Dragon|
Oh, these are fun...until they get out of hand. But, whatever. From my extremely limited knowledge of the source material...
Superman-The guy is a walking advertisement of the LG alignment. They call him the Big Blue Boyscout for a reason.
Batman-Dude I have no idea. Every different version of Batman gets such inconsistent depictions that the whole "he is every alignment" spreadsheet begin to sound more reasonable every year.
Joker-CE. "Some men just want to watch the world burn" or whatever.
Lex Luthor-Dunno. From what I remember as a kid from the old JLA cartoons, he always seemed NE. A villain willing to double-cross people but also holding to a certain standard. Maybe.
Spiderman-LG. Great power comes with yadda yadda yadda.
Captain America-So LG it's almost painful. "i don't want to kill people, i just don't like bullies." That's put him in the NG camp, but the fact that he sticks rigidly to what he believes is right no matter what, and has a strict code of...well, essentially honor that he adheres to sorta puts the Lawful in there.
The Punisher-Also no clue
Iron Man-All i know of Iron Man is from the movies, and there he seems like a mix between CN and CG. See, he seems initially selfish, but over time I sort of think he's generally a good guy who has MASSIVE authority and teamwork issues. So, CG. Mostly.
Thor-Again, all i know is the movies. Marvel comics were never something I got into. In those he seems...a vague mix between LG (at least in the later films) or something similar. he wants to do right by his dad and the honor his position demands. In the first film he was more CN.
Captain Kirk-NG? Hard to explain but that's the vibe I get.
Picard-Dunno. Never got to Next Gen
The Doctor-That's worse than the Batman one. Unlike Batman, who gets re-interpreted by different writers every few years but is still the same dude, the Doctor literally changes run to run. Like, not just in appearance, but in temperament as well. I'd say the Good part is in there, but whether he's L/N/C is impossible to pin down. Though I'd say the only truly full LG Doctor was probably John Hurt, and he's not technically "the Doctor" as he was a soldier at the time...soooooo...meh
Han Solo-I dunno, CG? CN initially, maybe?
