Awesome: The Adventures of Jimmy Neutron: Boy Genius
In the pilot movie, the entire sequence of the kids blasting off in amusement park rides modified to serve as interstellar spaceship, all to the tune of Kids in America. Made particularly awesome because the kids modified those rides by themselves with little more than some helpful direction from Jimmy. No one, and we mean no one, messes with their parents.
Cindy gets her moment in "The N Men" when she goes one-on-one with giant Hulk-Jimmy, only to realize that the only way to quell his anger is to get down on her hands and knees and apologize.
Hugh arguably also gets one of these in "Win, Lose and Kaboom", when he saves Team Earth by answering the alien pop culture question on a "Who Wants to Be a Millionaire" reminiscent game.
In the episode "Hall Monster", it was nice to see Jimmy assert his authority over his peers, for a whileat least.
Jimmy gets one in "Return of the Nanobots". In this episode, Jimmy frees the nanobots, only for them to go berserk trying to correct everybody. When his first attempt at creating a Logic Bomb results in them trying to erase humanity from existence, Jimmy's solution: trick them into calculating the exact value of pi. They promptly explode because of all the digits. It is cool seeing Jimmy defeat a villain as dangerous as them without his technology and only his brilliance.
