I think it's a bit of both. At the least, he rationalizes his hatred of Superman as mistrust of the alien's motives, and espouses this to those who'll listen--and in his internal monolgue, as in JLA #15 or somewhere around there, and (generally? often?) when he's written by Morrison. Also: "Obscene alien parasite!" But, sure, he's a total chode. I have been meaning to pick up the Lex-centric Action Comics issues of late. Thanks for the reminder.
No problem. It's going to be Lex centric for a long while...Supes will be showing up in the next arc. It's so weird that it's awesome.
Lex's robot companion makes the book worth the cash. Especially when "it" weapons up. And I have to agree with The Lensmen, a lot of the current LSH costumes--designed by Gary Frank, I believe--are pretty hideous. Timber Wolf and Shrinking Violet are particularly yucky.
I haven't paid much attention to the Legion costumes since I really don't have much reference for them. My understanding is that they were updated versions of the Silver Age Legion but I could be incorrect. As for Lex's robot companion that is partially what I was referring to as weird but awesome and totally in character for him.
Okay guys, we've still got 1000 years to change the future. Let's make the right choices. Start with fashion.
