Bruce Wayne sitting in the dark at the beginning (the junior novelization reveals it was one of the many times he was thinking about his parents) and then the bat signal shines in the room. he stands up, gets dressed and kicks ass.
Catwoman's spree in the mall and her greeting to Batman and Penguin as it blows up.
Especially since MP took out the manequins in only one take.
Catwoman's "debut" rescuing a woman from a rapist in a back alley- then turning on and scaring the crap out of the woman in disgust at her for being so weak. "You make it so easy, don't you? Always waiting for some Batman to save you? I am Catwoman. Hear me roar."
More than one film critic has argued that Michelle Pfeiffer's Catwoman in Batman Returns was the female performance of 1992. Perhaps her Crowning Moment comes when she interrupts a confrontation between Batman and the Penguin, who are outside Shreck's Department Store. She has been in there setting it up to explode (its owner, Max Shreck, tried to kill her and triggered her Start of Darkness) and with a series of acrobatic flips she emerges to the surprise of the men. She has one word for them: "Meow." As if on cue, the building explodes.
But in a close second? "You know, it's... a blur. I-I mean, not complete amnesia. I-I-I - I remember Sister Mary Margaret puking in church and Betsy Riley saying it was morning sickness and I remember the time I forgot to wear my underpants to school and the name of the boy who noticed was Ricky Friedberg." (smile vanishes) "He's dead now. But last night: complete blur. Couldn't you just die?"
Another Catwoman Moment of Awesome: As near the end, Shreck tries to shoot her, and she counts off each life she "lost" with every shot in a sing-song voice. "Seven! All Good Girls Go To Heaven!" but still kept on going, until she used a taser and a cut electrical chord to give him a literal Kiss of Death.
Shreck himself got one immediately before that, during his confrontation with Catwoman:
Catwoman: You killed me. The Penguin killed me. Batman killed me. That's three lives down, you got enough in there to finish me off? Shreck: One way to find out. Boom.
Shreck attempting to kill Kyle was pretty good; first he's all intimidating, pretends like he's not gonna do it, then does it.
The Penguin: After Batman completely ruins his kid-killing plan, he determines the logical step is to destroy the entire city. Using penguins armed with rocket launchers. His insanely hammy yet awesome "motivational" speech he gives to his penguin army has to be seen to be believed.
Penguin: My dear penguins, we stand on a great threshold. It's okay to be scared - many of you won't be coming back. Thanks to Batman, the time has come to punish ALL of God's children! First, second, third AND fourth born - why be biased?! Male and female! Hell, the sexes are equal with their erogenous zones......BLOWN SKY HIGH! FORWAAAARRDDD MARCH! THE LIBERATION OF GOTHAM HAS BEGUN!!
When he mocked Batman on their first meeting, then instantly turned serious and said "You don't really think you'll win, do you?"
Batman himself gets one immediately after that, turning Penguin's words back on him.
As if that wasn't enough, even Alfred knows that Bats' got this one in the bag, sharing a smug little smirk with him as Bruce coyly scratches the records as though he were a radio DJ broadcasting Gotham's newest #1 single.
His cracking into the Batmobile in order to cause carnage and make Batman look like a Card-Carrying Villain gets points for sheer audacity.
Batman saving the children at the beginning of the third act. Lightning flashes, his silhouette with cape spread like wings appears in front of the circus train. The driver is so distracted and petrified by fear that he doesn't notice Batman breaking into the cabin until it's too late. Textbook Batman.
Even the monkey is so terrified, that Batman made him go back to the lair and deliver a note to Penguin personally that states he failed epically. This became the first step in Penguin's Villainous Breakdown
