In Mulan, the Emperor bows to the heroine. The crowd hastily bows with him, and so does the slimy Obstructive Bureaucrat. Again, the music swells. Must feel pretty good for someone who has gone through the whole movie fearing and feeling she's not good enough. Doubles as both a heartwarming and awesome moment, as, just before that, Shan Yu had commanded the Emperor to Bow Before Zod, and the Emperor had calmly replied "No matter how the wind howls, the mountain cannot bow to it." That's right, folks, "the mountain" can not bow to the "howling wind", but it does bow to Fa Mulan.
Happens in Kung Fu Panda twice. Once in a dream sequence at the beginning of the movie in which Po dreams he's such a legendary warrior that the greatest warriors in China, the Furious Five, bow in respect to him. Also happens in the endgame, when Po defeats the Big Bad and the Furious Five actually do bow to him and call him a Master.
In Disney's The Sword in the Stone, Wart doesn't know what to make of the fact that everyone, including his belligerent foster father and stepbrother, are now kneeling to him.
Wreck-It Ralph: The racers of "Sugar Rush" who were mean to Vanellope (not of their own doing) now go to their knees begging forgiveness when the game resets puts Vanellope as the game's ruling princess, much to her own surprise.
Loki demands this of a crowd in Stuttgart, Germany in The Avengers (2012), and the scared crowd obliges, except for one elderly man who tells Loki that "there will always be men like you", and he would rather hold his head high and remain Defiant to the End than kneel before one. Loki moves to kill him before the heroes swoop in the nick of time and saves him and the crowd.
It also turns out that it was a bit of reasonable Genre Savvyness on Loki's part, as having the heroes defeat him and take him captive is part of his plan. This was given a musical treatment by Tumblr member MeganPhntmGrl.
During the subsequent fight in Stuttgart, he even attempts to forcefully make Captain America bow before him, but to no avail.
