Ron...Camp Wannaweep! (both in the first time and The Return to Camp Wannaweep episodes) where he faces off against Gill. Talk about Taking A Level in Badass. The side kick REALLY knows how to step up when the occasion calls for him to do so.
Kim fighting Duff for the first time in "Number One"... was awesome. Admit it, you too wished you could twirl around golf clubs like they were bow staffs-in some martial arts movie, looking so badass!
Ron when he first gets mystical monkey powers in "Monkey Fist Strikes", and he and Rufus kick Monkey Fist's butt big time! And Kim wasn't even around to help him at all! He defeated the villain all on his sidekicky own self! (ok, Rufus helped) But that seriously was one of Ron's most epic moments!
In "October 31st" Kim gets bonded to the Centurion project and manages take down Shego, Drakken and Duff Killigan effortlessly, just by using her thoughts.
Way back in "All The News", Kim gets her moment to shine as The Hero for once in a Sadistic Choice scenario when Adrena Lynn traps Ron and Brick on different rollercoaster Death Traps in an amusement park. Kim saves them both, without panicking or losing her cool even for a second!
The only time Ron matched his performance as good as when he was evil was probably in "The Twin Factor". Kim and Shego are both under Drakenīs control, and Ron has his hands tied (he allowed himself to be captured). Ron ran away, and Draken orders both to catch him, which they fail; I repeat: Ron, with his hands tied behind his back, single handily evaded Kim and Shego working together in close quarters.
Kim's speech to her dad and the rest of the NASA people about why she's not afraid to go into space. It's basically a long list of all the awesome thing's she's ever done, recounted in the most mundane manner possible.
A pre K Kim throwing down Drakken, Killigan and Fist. Then her present\future self shows up. After what they did, it was so satisfying. Followed by a Crowning Moment of Heartwarming when present!Kim watches her young self meet Ron.
Kim using her cheer leading gymnastic skills to jump through the laser beams that were accidentally activated at the vault to save the billionaire is also awesome.
Monique's entrance in Sitch in Time. 20 years of a workout INDEED!!! Double points for the awesome bazooka she got!
"Girlfriend, there was no way I was styling that *pointing to Shego* look!"-more double points for that she insulted Shego...and Shego didn't even come up with a comeback for that comment...she just sicked mooks on them instead of trying to deny it, or fire her own insult like she normally does when she and Kim would insult each others' fashion style. GO MONIQUE!!!
The appearance of Wade, Jim, and Tim's Future selves in Sitch in Time...full stop!
Ron in the end of A Sitch in Time, after Shego did the mistake about gloating about sending his mother to Norway, when he grabbed Drakken's arm and threw in into the wall, the same Drakken that had just beaten and captured Kim and Future Badass Monique working together. Seriously, Ron gets truly CMOA in both the movie, The Movie and the Grand Finale, while Kim hardly gets any of that...
Ron:You're the reason I'VE BEEN EATING MEATCAKES?! Drakken: Sit back! * Ron grabs his arm and throws him across the room*
Here's one for Kim. In "Hidden Talent" it is revealed that she's really bad at singing high notes, but Ron entered her into the talent show anyway. Drakken then decides to put her into particularly elaborate trap that makes even Shego wonders if they're overdoing it: still, Kim escapes from being chained up in a solid steel box filling up with water and sinking into a bottomless pit, beats a shark and giant squid, uses that terrible high note to break the six feet of solid ice covering the pit, beats up Shego, Drakken, and all their henchmen, teleports back to her high school and rushes onstage just in time to put on a good performance, without breaking at the high notes.
"Triple S" was A Day in the Limelight episode of awesome for both Senior Senior Senior and Junior. For Senior? After losing his fortune to a swindler named Vinnie, he takes it upon himself to steal back what is his, using nothing but his long-dormant X-Games skills and actually out-maneuvered Kim in a sweet skydiving battle. For Junior? Pulling off an excellent last-minute Batman Gambit by pretending to pull a Heel-Face Turn and turn in his father, only to reveal to Senior that he did so he could collect on Vinnie's recently posted $2 Billion reward and use it to break out Senior later, effectively retrieving their fortune from Vinnie with Kim Possible being none the wiser.
In "Bad Boy" there was an accident with the Attitudinator where Drakken & Ron switched alignments. Ron proceeded to turn his tricycle into a death cannon so he could blow up his evil cousin at his better cousin's wedding. Shego was so impressed, she ditched Drakken and recruited Ron, but then he started to push her around. Shego didn't like that, so she fired a plasma bolt at him. He casually activates a shield and remarks that he found it in Drakken's stuff and doubted he knew how to use it. He presses a button that opens the floor into a crocodile tank and remarks that henchpersons should know their place. SHEGO STUTTERS, SHOCKED, AND BACKS OFF!! So, yeah. Ron is the best Disney villain ever.
Evil Ron: BOOOOO YAH HA HA HA!!!
You do NOT mess with Zorpox the Conqueror.
In "Overdue", Ron has to Run the Gauntlet while searching for Kim's missing library book. In less time than it takes Kim to do one mission, he ended several villain plots. With just the Wadebot to stand in for Kim.
And who could forget Wade in the episode where Team Impossible tries to take over the saving-the-world business. Wade tries to hack their systems, but they spike him. After crying and collapsing into a bubbling heap of worthlessness, he realizes that NOBODY SPIKES HIS SYSTEMS!!!
Ron: Dude, you are so over. Dash Daman: I can take her [Kim]. Ron: Nope. Rufus: Sorry. Dash: Do you know what I'm capable of? Ron: I've got a general idea. Dash: And? Ron: Dude, you are so over. Dash: Let's just see about that. (An explosion rocks the base, and Wade slowly walks out of the smoke.) Wade: Nobody, NOBODY SPIKES MY SYSTEM!!! Kim: Wade? Ron: Wade?In person? (to Dash) Dude, now you are so over, I don't even want to stand near you! (backs to Wade) Wow. you have really perfected the Holo-Wade. Wade: It's really me, Ron. Ron: Yeah right. If it were really you, I couldn't do this. (reaches out to touch Wade, who smacks his hand back, then walks forward, leaving Ron stuttering) Dash: Team Impossible is the world's greatest team of high danger operatives. We will NOT be intimidated by children.
What Ron's really talking about (before Wade appears) is Kim: she's pissed that they're disrupting her hero work because it cuts into their profit margins. Ron just steps back as if the fight between a pro team of "heroes" and Ms. I-Can-Do-Anything is a Foregone Conclusion. He's right.
And Wade defeats them with the laser system introduced in "A Sitch In Time", which Team Impossible had implemented in their base. When they end up unable to get themselves out of the situation after Wade tosses the remote across the room, Kim gets through with ease just like in her first case.
The first seconds of the season four opener. When demand for a Post Script Season brought it on the writers responded with this.
Wade coming over personally with Kim and Ron in "The Cupid Effect" (with Monique along for the ride) to stop the Seniors' plan.
Warmonga's first appearance. She defeats Shego and Kim consecutively and Kim's wearing the battlesuit.
In the episode where the attitudinator ends up in the hands of a Team Go villain, she turns Shego good and the rest of Team Go evil. That's not the crowning moment of awesome; the crowning moment of awesome is all Ron's when he gets turned evil.
Kim: Not again... Hego: What's wrong with him? Shego: I think he's evil now. Hego: Oh. How bad could that be? Shego: You'd be surprised.
He then proceeds to single-handedly pummel Team Go (all of whom have superpowers), proceeds to take the attitudinator from the villain, beat her up too, and notes offhandedly that she's a lousy villain and she should have turned Kim evil first. He almost does it too.
He doesn't just take on the Wego clones with ease. He becomes a complete third party in the entire fight. Attacking both good and bad sides in an epic ballet of masterful monkey kung-fu.
Same episode, we get a glimpse of how good Team Go is when Shego gets her brothers in their act. For most of the episode, Electronique was rather sure of her victory, even when after a round with Zorpox. The moment she realizes the entire Team Go is good again, she is in Oh, Crap mode. Three seconds later, a villain who could hold her own against Evil!Ron had completely ceased resisting or escaping. Three.Seconds.Flat.
Mr. Barkin: Interesting report you handed in there, Stoppable... Your dad, A.K.A. "hero", is a member of the Middleton Search and Rescue? Ron: Yep. Mr. Barkin: Also volunteers at the local fire department? Ron: Affirmative. Mr. Barkin: And while in the confines of a certain Infinity Dome, he can convert pure mathematical thought into blasts of energy that fires out of his skull?! Ron: Yeah, it's an actuary thing. Mr. Barkin: I see... (Beat) YOUR DAD ROCKS!! A+!!
Speaking of which, when Mr. Stoppable steps up to fight the Mathter:
Mr Stoppable: I'm no hero. I'm Actuary of the Year. cue epic battle.
A rather minor one, but in one episode where Bonnie's cruelty towards Kim really goes too far (she tries to drive a wedge between her and Ron), Kim very nearly loses it and Bonnie backs down instantly. The fact that just the prospect of a real fight with Kim causes Bonnie to break down in tears is a CMOA for Kim in my book.
Drakken's crowning moment. The flower vines ROCK.
Ron's CMOA was in the last episode when Ron Went mystical monkey style, and threw two villains into a crashing spaceship. It was so CMOA that Kim (and Shego) were speechless.
In the crossover episode of Kim Possible and Lilo & Stitch. it is revealed that Rufus is an experiment that is so dangerous that Jumba spends most of the episode trying to catch it so it wouldn't destroy the Earth. Turns out he got the wrong Rufus, but wouldn't it have been awesome if that were canon?
The opening theme. The entire intro to the both the first three seasons and season 4! They are awesome! The song is awesome, the clips moved with it are awesome! It's flat out awesome!!!
Any time Kim and Shego go one on one...it's awesome! Sometimes has shades of CMOF with their hilarious back and forth witty banter.
