In an alternate universe, Lois Lane was a reporter for the Daily Planet.
Lois was killed while investigating Intergang for a story. Superman arrived a few seconds too late to save her. It was this event that lead Superman to seek an alliance with Lex Luthor and take over Metropolis to eliminate crime. He didn't realize the mistake he'd made until a Lois Lane from another universe arrived and showed him what Luthor had done with his new position.
