>>86229827You also have to keep in mind a few important factors about this Lex:
He never had a run in with Superboy so he never lost his hair (though I have no idea if this is the new52 origin since I haven't read much of that, just the older comics).
He has never lost and has always gotten everything he's ever wanted, except for his father's abuse which is his one canonical "loss" and is one of the main reasons why he's so triggered by it. This explains his supreme confidence and the fact that the entire US military is afraid of him. ALSO, and this is big, due to him never losing it causes him to talk with a much higher confidence level than his usual calmer counterparts (it has been said that he gets calmer in later movies). I do personally believe he would be of a much higher energy if he never experienced the loss or bullying that he does in certain iterations.
Anything/anyone which gives even the potential at removing him from the top causes him to lash out (perhaps due to remembering his father). This explains the courthouse explosion and his want to genocide all metahumans starting with Superman.
He is incredibly petty and prideful, thus leading to the jar of urine "joke" he does to the senator as well as the special bullets he uses in Africa. He LOVES knowing that people know he did it but can't do anything about it.
