No real reason to do that. Things are going his way perfectly well enough as they are. The heroines aren't strong enough to 100% guarantee a win and it could just as well end up going sideways since the heroes could end fighting them off and finding out what Lex is doing or even destroy the devices somehow.I was just thinking, Lex talks about the Justice League finding out what he's doing. So I thought, wouldn't it be cool if at somepoint in the game Lex attacks the watchtower and turns all the girl's he captured against the hero's.
Wouldn't be very smart of him.
