An ancient artifact in the [i][[Kirby (series)|]][/i] games, introduced in [i][[Kirby's Return to Dream Land]][/i]. It is said to give its wearer unlimited power.

[spoiler]The main story of [i]Kirby's Return to Dream Land[/i] is driven by [[Magolor]]'s efforts to steal the Crown from its current guardian, [[Landia]]. After enlisting the help of [[Kirby]] [[king_dedede|and]] [[meta_knight|his]] [[bandana_waddle_dee|friends]], he succeeds in doing so and attempts to conquer the universe, starting with [[Pop Star]]. The Crown's influence and evil sentience get the better of him and he transforms into a [[magolor_soul|monster]] that is swiftly defeated by Kirby and company.[/spoiler]

[spoiler][[Void Termina]] is able to summon the Crown (or at least a replica of it) during his boss battle in [i][[Kirby: Star Allies]][/i]. This along with the Jambastion sigil closely resembling the Crown suggests a strong connection with him, [[Dark Matter (kirby)|]], and the twisted treasure.[/spoiler]

[spoiler][i][[Kirby's Return to Dream Land Deluxe]][/i] confirms that the Master Crown is in fact, sentient, having brought the downfall of multiple civilizations in the past. In the [i][[Magolor Epilogue]][/i], it first enhances the [[Grand Doomer]] into the Crowned Doomer, then assimilates the [[Gem Apple]] to turn into [[master crown (tree)|a tree monster]] before being poetically struck down by Magolor’s [[Ultra Sword]].[/spoiler]
