Lex Luthor is one of the single most recognizable villains in comics. So much so that he's actually become a bit of a cliche; even people that aren't fans of superheros (they exist, I've met them) will immediately recognize him. Most bad guys will have their stories change wildly over the years as they are redesigned to serve the characters they battle, Lex has been around and been at the forefront of the story for SO long he actually has more than one fully-formed comic identity.
Lex's Comic History
Lex was originally depicted as a classic evil scientist. They were popular characters in early serials which were very much the birthing ground of the concepts in early super-hero comics, and Lex is easily the ultimate expression of that whole concept. He continued in that vein for decades, his overall effectiveness waxing and waning with the prevailing notion of just how dangerous comic villains should be. This was the version of the character that Gene Hackman played in the Richard Donner Superman movies, and also the version of the character that started wearing green power-armor in the Challenge of the Super-Friends. He underwent a massive change in 1986 when John Byrne started the entire Superman story from scratch, and created a completely new story for Lex. Now, he was a intensely evil, corrupt businessman. This new story gave him, arguably, a far greater capacity for evil, and also explained the fact that he was constantly able to avoid the repercussions of his actions. This change had it's detractors, but it also gave us amazing stories, like Brian Azzarrellos's Lex Luthor: Man of Steel miniseries, Jeph Loeb's introduction of him running for (and winning!) the presidency, and of course the ground breaking Superman Animated Series. Writers like Loeb and Geoff Johns had done a lot of work to try to merge the two versions, and in many cases doing so actually makes the entire arc of Superman make a lot more sense.
Our Lex Luthor Story
As awesome as characters like Lex are, the important thing to remember is that they exist to serve a larger story. Lex is Superman's archnemesis, but he's much more than that. He's a cornerstone of that character's world. He's responsible for the existance of several of Superman's best villains like Parasite and Bizarro, and he has also come to his aide more than once when the city they both love is in danger. He's of course such a huge character that he's effected the rest of the DC universe at large as well; the earthquake that decimated Gotham was entirely his doing, and of course he made himself one of the greatest enemies of the Justice League when he assembled the Injustice Gang.
Of course, there are quite a few stories we've left out of our version. Most of them aren't even worth mentioning, but Perhaps the biggest change was the removal of his childhood friendship with Clark Kent in Smallville. This is a holdover from the old Superboy Comics, most of which we cut out.
Lex Luthor's Costume
The eventual innovation of giving Lex his own battle armor is almost inevitable, but the finale of the animated series probably did it best when he appeared in the final moments back in his classic Armani and quipped 'I had to get my power suit.' Lex is ultimately at his absolute best as a man who thinks he has ultimate power and who is then confronted with just how very powerless he really is.
The entire point of Superman is to present us with a unflappably good person using his unlimited power to always do the right thing. It's meant to inspire. When he was first created, his enemies were corrupt landlords and evil businessmen. The character concept NEEDS that counterpoint representing the worst of humanity. Lex has become the ultimate expression of that, but there's a strong element of human falibility in him, and ultimately of tragedy. If the future of Superman's story is to be a father, to bask in the experience of being human... It might make sense for Luthor to somehow distance himself from his humanity. We're not sure what form this might take.
