Prince Caspian/Awesome

Trumpkin the dwarf, despite having no belief whatsoever in Aslan, High King Peter, or Susan's horn, declares that he will take on the errand of going to meet whatever help the horn calls up: "You are my King. I know the difference between giving advice and giving orders. You have my advice and now it's the time for orders."
Peter in Prince Caspian is essentially a series of CMoAs. Re-enter the High King of Narnia, who may be an English schoolboy but also happens to be a brilliant leader, seasoned warrior, excellent strategist and wise counsellor. Lewis gets extra points for showing exactly why Peter is the High King over all kings in Narnia without turning him into a Marty Stu.
Edmund gets some of this too. Read the chapter where he turns up to give the challenge to Miraz. Glozelle and Sopespian notice him going to Miraz's tent and have brief swooning session over his aura of badassitude.
- The White Which tempts Caspian and then Peter with the promise of power, but Edmund get a Moment of Awesome when he stabs her from behind and breaks her spell. Just the whole look on his face, coupled with how he succumbed to her temptations in the first movie but obviously learned something from the experience.
  - The entire White Witch encounter was only in The Film of the Book. The hag and the Werewolf book only got as far as suggesting raising her - though Peter's and Edmund's Big Damn Heroes moment where they burst in in time to stop the ritual from starting is still pretty Badass.
- These are some other CMOAs Edmund got in the Film of the Book:
  - Throughly smacking down a guard during the assault on the castle with a flashlight.
  - Falling backwards off the tower to be picked up by a griffin.
  - And a minor one when he says this to Miraz: "So you're bravely refusing to fight a man half your age?"
  - In the final battle he steals a crossbow from a Telmarine soldier and uses it to great effect, when his sibling give hime dirty looks he gives them one of his own that basically amounts to "Deal with it."
- Edmund siding with Lucy about changing their plans and going down the gorge where she saw Aslan, because even though he can't see anything, he owes her one from the first book. And later, Lucy pointing out that they're going to have to go down the gorge after all -- without, as Peter points out, saying "I told you so."
- When the Pevensies meet Trumpkin, and he is unconvinced that the Horn actually called them to Narnia, Edmund offers to fight him (in place of Peter) so that if he loses, it won't be such a loss for them, but if he wins, it will be in their favour. His fight is awesome, and so is Susan's archery competition, mainly due to Trumpkin's growing disbelief as he's bested by schoolchildren.
Aslan roars to awaken the dryads (tree nymphs). And not just any roar, one that echos and carries across a huge distance and rolls across the plains like thunder. Done epically well in the radio drama, not so much in the movie.
Everything Reepicheep does.
- His mice get one when he gets his tail cut off. Lucy heals him, but her cordial can't restore his severed tail. Whereupon the mice draw their swords to cut off their own tails, declaring that they will not retain an honor denied their leader. Which could also double as a Crowning Moment of Heartwarming. Either way, Aslan is so pleased by their devotion that he gives Reepicheep his tail back.
Aslan, the girls and the Old Narnians running around putting Narnia to rights while the battle is being won -- the nicest, gentlest Roaring Rampage of Revenge ever (although it works best if you don't apply Fridge Logic to questions such as whether it's really okay to turn small boys into pigs because they've been bratty to their teacher). (Actually, the book doesn't explicitly say that they got turned into pigs; it says that the boys were never seen again, but a bunch of pigs turned up; which could mean anything or nothing.)
