How did Lex Luthor and Superman fight an became the biggest Enemies?

SupermanHow did Lex Luthor and Superman fight an became the biggest Enemies?it all depends on which 'Origin story' you embrace



in the early days when Lex was a mad scientist, it was simple, Superman Stopped Lex, the bulk of all of Lex's future plans had step 1 being to remove Superman



-- much the same for 'Criminal mastermind' Lex after that



-- in the 1980's Reboot Man of Steel, which ret-conned Lex into the Billionaire Businessman, Lex tried to Hire Superman, Superman said 'No' which few if any people ever did, and there was a matter of Lex setting up a Possibly fatal situation to get Superman's attention, for which Superman was deputized by the Mayor and Lex was arrested -- this was pretty much canon from the 1986 Crisis arc through 2000 at least



the 04 Birthright and now the newer Secret Origin ret-conned the situation yet again... as far as I know the current point of friction is equal parts 'can't be bought' and that Lex Likely tried to Kill Lional and Superboy saved him anonymously, and Lex did the math that the mysterious savoir and the new Hero in town were the sameHow did Lex Luthor and Superman fight an became the biggest Enemies?depends;



in the comics, superman stood in the way of luthor's designs to rule the world. and so luthor vowed to destroy him. and i believe luthor was the first to figure out supe's weakness to green k. thus giving the mortal man a means to that end.



in other media, say smallville, lex and supes becme enemies because of a break in trust, and percieved betrayal.
