Why does king d-d-d hate Kirby?

King Dedede dislikes Kirby primarily because Kirby constantly thwarts his plans and undermines his authority in Dream Land. Dedede's attempts to maintain control and power are repeatedly foiled by Kirby's heroic actions and abilities. Additionally, Kirby's cheerful nature and popularity among the inhabitants of Dream Land further exacerbate Dedede's jealousy and resentment. This rivalry is a central theme in their encounters throughout the franchise.
