The Good Prince is a Crowning Story of Awesome for Flycatcher
Homelands is a Crowning Story of Awesome for Boy Blue.
I don't care if she didn't kill him dead. The fight between Totenkinder and Dark is just pure awesome, especially when she reveals her preference for using candy... which rots your teeth. Even the ones you stole. That's right: Totenkinder/Bellflower weaponized Candyland.
It gets even more awesome when we find out that all the way up to just before the last fight with the North Wind, Mr. Dark is still feeling the after effects of that fight, and still weakened because of it. And then when you consider that this weakness dooms him in the fight with the North Wind, which would otherwise have been a battle of equals with an uncertain outcome AND the fight with the North Wind was deliberately set up by Totenkinder when she revealed Ghosts' existence to him, it means that in the final analysis, she won. Though in the process she essentially assassinated the North Wind.
In issue #8, Shere Khan, after stalking Snow White through the wilderness for over thirty miles, finally corners her and pounces. And then she empties a revolver into him.
In issue #9, Snow puts down the revolt at the farm by walking out, alone and unarmed, into the village square and ordering the rebels to throw down their guns and disperse, to which Papa Bear replies "But we've got you outgunned!" Snow comes back with an immortal retort: "You dumb bastards! I'm Snow White! I run Fabletown and I'm never outgunned!" Then she calls in an airstrike. From a dragon.
Of course, things kind of go sideways for Snow when Goldilocks shoots her in the head with a sniper rifle. Snow White survives, though, and that just means that she gets another crowning moment of awesome when Goldilocks tries to kill her and the Big Bad Wolf in issue #17: Snow sneaks up behind her, buries an axe in Goldilocks' head, and then beats her with her cane until Goldilocks falls down a cliff into the path of an oncoming semi.
Oh, and it's a bad idea to ask about the Seven Dwarfs. Yeah, Snow White is pretty badass.
Of course, the Big Bad "Bigby" Wolf is no slouch either. In "March of the Wooden Soldiers," just as the eponymous invaders are about to overrun Fabletown's defenses, Bigby shows up in the nick of time and literally blows them away with the ol' huff and puff. It then turns into a Crowning Moment of Heartwarming when Snow, by this point massively pregnant with Bigby's cubs, rushes out into the pouring rain to embrace him.
Frau Totenkinder's defeat of Baba Yaga during that same battle was pretty kickass too. Made especially awesome by the fact that Baba Yaga was totally assured of her victory when she flew up to fight Totenkinder, since the Fables are at least partially fueled by Popularity Power... only to have Totenkinder reveal that most of the nameless witches in European folklore are actually her. The battle that follows isn't shown on panel, except for a brief moment where King Cole views it and it's reflected on his glasses that two awful looking creatures are going at it (whether these are summons or shapeshifted witches is hard to say). The sight terrifies Cole so much that he bars anyone from going up to the scene of the fight until they're sure it's over. At the end of the fight, Frau is drenched, but otherwise whole, and has calmly resumed her knitting, while Baba Yaga lies barely alive and struggling to remain conscious on the ground before her.
A subtle moment of awesome for the illustrators. A reflection of the battle can be seen on the panel, in which we see monstrous serpentine dragons doing battle. It is the same dragon Totenkinder transforms into when she fights Mr. Dark.
Boy Blue gets one when he fights off wooden soldiers with the Vorpal sword, which has been duct-taped to his hands because they were too injured (after several days of torture) to hold it any other way.
King Cole's reappearance in the Arabian Days and Nights arc. Having spent a few months, if not years, off-page feeling rejected and depressed for having been voted out of office as Mayor of Fabletown, he sweeps back onto the page smoothly defusing an already-in-progress diplomatic explosion. In perfect Arabic.
Rose Red's recovery from her Heroic BSOD over Boy Blue's death is one giant CMOA. She instantly shuts down Geppetto's bid for leadership of the Farm, tells Beast and Beauty and all the rest who worked in the Fabletown mayor's office, who were used to being in charge that SHE(Rose Red) was the one in charge of the Farm and if they don't like it, they can take a hike. She also got Brock Blueheart and his flock on her side and convinced them to work together rather than just sit around waiting for Boy Blue to return to fix everything.
Pinnochio gets his revenge for centuries of being eternally a child on the Blue Fairy and easily beats her down.
The first arc in Fairest has both the now good Snow Queen and Briar Rose going up against Hadeon the Destroyer, the evil fairy who put the death curse on Briar when she was a baby. Lumi holds her own for a while, until finally Briar steps in, royally pissed off that Hadeon tried to kill her simply because she wasn't invited to her christening. And none of Hadeon's spells have any effect on Briar. The reason is because, technically, Hadeon's original death curse did work even if it was changed slightly. Hadeon's powers are aware that curse was fulfilled, so they perceive Briar to be dead and won't exceed themselves on a target they've already felled. Seems Hadeon set a type of Department of Redundancy Department filter on her magic to conserve her resources, which in hindsight is not a good idea when you're engaging in combat with beings that can come back from the dead.
Bigby: Let me in or I'll rip your fucking throat out.
In the Rose Red edition, when the titular character reclaims her leadership after coming out of her Heroic BSOD, the tree dryads that Geppetto had created as bodyguards at one point tells her to watch her tongue around him, or they'll make sure to punish her should she repeat herself. To this, Rose Red casually orders Clara (her dragon sidekick in a raven's body) to burn "Grandfather Oak" that the dryads were made from to the ground "the next time any of these three bozos threatens me, verbally or physically." And likewise, this exchange later:
Female dryad: We'll need to find a way to work with each other, miss Red. My brother and I have an obligation to protect Geppetto. We can't do that while under a constant threat to have our sacred patriarch burned.
Rose Red: No, princess Alder. We don't need to find a way to work with each other, because you two won't be here much longer. Your job is over. By nightfall, if you two dryads are still lurking around the farm, you'll be arrested, or worse.
Female dryad: But..?!
Rose Red: No one gets special treatment on my farm. No one gets bodyguards. I don't abide hired thugs. Now, move along and send the next fable in.
