Just discovered your page, and love your work. As far as Lex Luthor's family goes, I've always imagined a legacy (that ironically they are mostly unaware of), with 'Golden Age' Luthor (Blofeld before there was a Blofeld) as the grandfather (with Lilian as his daughter) trying to start a world war to profit, followed by Lionel (sleazy businessman Luthor), and Lex getting to be the modern version (who encompasses scientist, arms-dealer and businessman - and even politician).
I love your take on the Luthor fam, honestly!
I gotta admit I take a lot of inspiration from the Smallville TV show for most of Luthor’s backstory. In my AU, Lionel’s dad was a drunk crook who beat the crap out of his wife and kid. Lillian came from a rich family and Lionel basically married her for the money.
I wanted to keep that 'poor guy who clawed his way up' kind of Lionel because I’ve known people like that, born poor ended up rich, and honestly, they were some of the most toxic and manipulative people I’ve ever met. Weirdly enough, the ones born rich were usually more chill. Not saying it's a universal thing (my own grandpa was a born poor ended up rich guy... before he lost everything because he was too nice) but I like slipping little bits of my own experience into what I write.
