The Fairly OddParents S02E15 - Mighty Mom and Dyno Dad

Timmy, tired of his parents rushing to work and coming home late and tired, thus never having any time for him, wishes his parents had superpowers, but they are too busy saving the world to even spend time with him. Timmy must now become the ultimate villain (a parody of Galactus) to get his parents to give up their superpowers (his wish made them powerful enough that not even magic would affect them, so they must willingly give up their powers).
