Norm the Genie getting angry at Jorgen Von Strangle after Jorgen pulls Norm's wings off. The Designated Hero and his Fairy Companions are just all being Neutral Female and Norm so totally stands up to Jorgen. Also, considering that Jorgen scares the entire universe stiff (including Norm), that makes it more awesome.
Also Norm managed to someone unintentionally get Jorgen to run away from him in "Gimme the Wand" and when he comes in the room, Timmy tends to get scared or angry then recite Norm's species, deeds and believed alignment. You have to be pretty Badass to be able to get your enemies to say your Badass Boast for you.
The Shapeshifting in "GimmetheWand" was so fast that it has to be AWESOME!!!!!
Poof gets one when his fart restores the universe. That's the most Badass fart in the history of Western Animation!
On the most recent Fairly Odd Parents movie, Cosmo and Wanda's newborn son has been kidnapped by H.P. and Anti-Cosmo. Wanda tells them, "If you so much as lay a hand on our baby, I'll destroy both of you!" It did sound a bit forced, but was worth it to hear her threatening to single-handedly murder them.
Timmy gets one later when he reveals his initial plan not working was actually the first part of The Plan, and breaks the team out of their butterfly net. Jorgen compliments Timmy, and is interrupted by Timmy telling him to dance. He does. Keep in mind Jorgen was wearing a bunny suit.
In "Abracatasprophe", when Timmy tells his parents and Mr. Crocker about his fairies.
"The truth will set you free!"
And then, after they're taken away forever, due to him telling people about them (in order to free them from Crocker), he munches on what's left of the Rule-Free-Wish-Muffin and wishes them back. Awesome.
Another one for Timmy is the entire fight with Crocker in "Abracatastrophe". It's also one of those few times that shows just how clever Timmy is when plot necessitates it, using the previously selfish seeming magic items he'd wished for earlier in the movie to CONSTANTLY counter Crocker's moves.
Tootie gets her CMOA when she finds the Timmy doll in "You Doo!" Not realizing the doll controls what happens to Timmy, she starts playing with it, moving its head around as if it's saying what she'd like Timmy to say. At that very moment, Timmy is having lunch with Trixie (who he has put under his own control) and is about to say something sweet to her, but thanks to Tootie messing around with the Yoodoo doll of him, she gets him to instead say that Tootie is the one he loves and has him insult Trixie at the same time.
The Darkness in Wishology had one in Part Three:
Lead Eliminator: (pointing his weapon at the darkness) You cannot make me!
(fires laser into Darkness, Darkness cringes a bit before reverting to normal)
Darkness: But I can UNmake you. (does so)
In Wishology part two, Timmy's fairies and all of his friends and allies are captured. So what does he do? He gathers up his enemies to help him.
Timmy gets one in "Information Stupor Highway" after he avoids getting chewed out by Crocker's virus and THEN sends a viral picture of Crocker in a red rubber dress for everyone to laugh at!
Mr. Crocker himself gets one of these in No Subsitute For Crazy. Not only does he save Timmy in a brief Enemy Mine moment, but he also single-handedly defeats Miss Sunshine Ms. Doombringer by literally putting her on a bus...or rather, having the bus hit her.
"They always run..."
The Pixies free-styling against Timmy in "Where is the Fun?" in the School's Out musical, which convinces Flappy Bob to essentially sign the entire world over to them: "It's over, Turner! YOU LOSE!"
Timmy and Trixie's kiss near the end of the second part of Wishology.
Tootie, after being passed off as a psychotic stalker that Timmy would never ever like by some fans and writers for years, is revealed to grow up to be quite beautiful and smart in the future, and ironically Timmy becomes the one chasing her in the live action movie that takes place 13 years after FOP.
Timmy and Tootie's kiss at the end of the live-action movie qualifies, since it ends up saving lives of Timmy's fairies.
