Superman: The Animated Series – Heroes Lois

She does not blunder stupidly into dangerous situations, she’s well aware of the hazards before she goes in. Owing to his super powers,
Clark will often spot danger that no one else can see and caution her to watch herself. She takes his warnings as his attempt to sabotage her and get the story for himself. She has a like/hate relationship with Clark, always referring to him as "Kent", unless she wants something out of him and only then does she call him "Clark". Deep inside she does have a bit of affection for him, but their rivalry has her keeping him at arm’s length, And even if they weren’t rivals, she’d still find him a stiff, by-the-books kinda guy.
Lois has sources all over Metropolis, from high society industrialists to the lovable Hobb’s Bay fisherman Bibbo. Opinionated and quick with a quip among the mostly male members of the Planet reporting staff, Lois can talk rings around most men, her boss Perry White included. There’s only one man who leaves her at a loss for words: Superman and she could kick herself for it. A million available men in Metropolis and she falls for an alien.

But then, Lois has always had an attraction for danger. She always takes the toughest assignment and would gladly infiltrate an arch-villain’s lair if it meant getting a scoop. Her affinity for danger extends into her personal life as well. Lois has always liked edgy, mysterious men who played by their own rules. She even dated Lex Luthor for a while.
But as soon as she learned Lex wanted her to write some pro-Lex Corp pieces for the Planet, she dropped him faster than Superman would drop a hunk of Kryptonite.

Being a reporter, Lois can’t but help be a little suspicious of
Superman. Is he for real? Where did he come from? Is he really as good as he seems? What does he really want here on Earth? There are a thousand questions she wants to ask him and if she ever got that interview, her Pulitzer prize would be assured. Although Lois will initially take a skeptical, even cynical attitude toward Superman, the more she’ll see him risking his life to help others the more she’ll be convinced that he is "for real". She can’t help but feel attracted to him.

She’s always believed that no one ever gives anything away for free, but
Superman’s selflessness is gradually changing her mind.

Bio (Cartoon Network): Lois Lane is the Daily Planet’s top reporter. She and Clark are always trying to scoop each other for the best stories. The very stubborn and crafty Lois regards Clark as a somewhat rigid goody-two-shoes. Yet she must admit that Clark is a darn good journalist. For this reason, she also treats him with the respect that any worthy rival is due. Lois employs equal combinations of daring and cunning to get her stories, stopping at almost nothing to get exactly what she wants. She is tough and opinionated and generally regarded as one of the best in the biz. Lois is especially attracted to
Superman. The mysterious alien outsider gets this reporter’s blood racing. What’s his story? What does he want? And who is the man behind the cape? Lois is determined to find out. Of course, there may be a more, shall we say, primal source of Lois’ fixation with Superman.
