{{quote|I did it! It all went according to plan! I got the sun and moon to fight. I got you to go into space... it was all according to my perfect little plan! Now I can cause all the mischief I want! Haha! See you later!|'''Marx''' in [[Milky Way Wishes]], ''[[Kirby Super Star Ultra]]''}}
<onlyinclude>{{#ifeq:{{{transcludesection|}}}|lead|
'''Marx''' is a mischievous, small, round, jester-like creature from [[Popstar]] who serves as the final [[boss]] and main antagonist of [[Milky Way Wishes]] from ''[[Kirby Super Star]]'' and its remake, ''[[Kirby Super Star Ultra]]''. In this role, he feigns to be [[Kirby]]'s ally and instructs him to summon [[Galactic Nova]] to stop the Sun and Moon from fighting, but then steals Kirby's wish at just the right moment to gain immense magical power. With this power, Marx intends to take over Popstar so that he can cause all the mischief he wants, so Kirby uses the [[Starship]] to chase him down and defeats both him and Galactic Nova, sending Marx careening into Nova to blow it to smithereens. In [[The True Arena]], Marx is subsequently reincarnated into [[Marx Soul]] by absorbing pieces of the destroyed Nova, forcing Kirby to battle him again, though whether or not this battle officially happens in the same [[continuity]] of Milky Way Wishes is not confirmed.

Since this initial set of appearances, Marx has frequently appeared in subsequent games, though usually as little more than a cameo or reference. He would become playable for the first time as a [[Dream Friend]] in ''[[Kirby Star Allies]]'', where his moveset mainly revolves around using his ball as a projectile and using his attacks as a boss in ''Kirby Super Star''. Many of those latter attacks would be referenced and reused by subsequent final bosses in the ''Kirby'' series, with the most commonly-referenced attacks including [[Black Hole]], "Marx Cannon", and [[Shooter Cutter]]. His character arc (and several of his attacks) would also be directly referenced by [[Magolor]], and the two would subsequently become associated in various external media for the franchise. Marx has also made appearances outside of the ''Kirby'' series, with the most notable being his inclusion as a boss in ''[[Super Smash Bros. Ultimate]]''. His name is likely based on the Marx Brothers, as they were famous comedians.
}}</onlyinclude>{{:{{ROOTPAGENAME}}|transcludesection=lead}}

==Characteristics==
In his default form, Marx is lavender and round with large purple eyes, no arms, a red bow tie, brown shoes, and a jester hat which has a style and color scheme similar to [[Mirror]] Kirby's hat in older games, being blue with wite circles of the left and red with white triangles on the right. His eyes are rather large and bulbous when compared to his body, and are very rounded. He typically has an open smile on his face, with two small fangs showing if he smiles wide enough. These fangs are more prominent when Marx shows his true form. Marx is often seen balancing and rolling around on an inflatable ball like a clown, and can punt this ball at his enemies to attack them in ''Kirby Star Allies''.

Marx's true form has a large pair of wings made of glowing floating hexagonal crystals which shift in color and are supported by two golden arm-like appendages with claws on them and red heart-shaped jewels embeded on the alulas. This form of Marx has a longer bow tie and much more menacing eyes. He also becomes somewhat larger in stature, at least when fought as a boss in ''Kirby Super Star''. In ''Kirby Star Allies'', Marx can assume this form at will in order to fly around and access his more potent moves.

[[File:KSS Cutscene Marx sprite.png|left]]
[[File:KSS Marxs wish.png|thumb|200px|Marx wishing to Nova for control over Popstar.]]
Marx makes his debut and most defining appearance in ''[[Kirby Super Star]]'' and its remake ''[[Kirby Super Star Ultra]]'' as a character in [[Milky Way Wishes]]. Here, he appears before Kirby to inform him that the only way to stop the Sun and Moon from fighting is to gather the stars from each planet surrounding Popstar and use their power to summon the great [[Galactic Nova|comet Nova]], who can grant the wishes of whoever summons it. While seeming innocent at first, when Kirby carries out this task and calls forth the Nova, Marx boots the pink puffball aside and steals his wish, making it known to Nova his desire to rule over Popstar. From here, Marx assumes his menacing true form and gloats to Kirby about having orchestrated the whole scenario to grab this opportunity at power, then leaves Kirby to float aimlessly in space. However, Kirby is able to rally the stars he collected and chase after Nova and Marx using the [[Starship]].

}}
After the Galactic Nova stage is cleared, Kirby is automatically thrown onto an unknown planet where he must do battle with Marx in his powered-up state.  In this fight, Marx uses a variety of outlandish attacks, including dropping seeds that rapidly sprout as spiky vines, shooting lasers from his mouth, and splitting himself in half to create a black hole. Despite these horrific powers, Kirby is able to overcome the traitorous jester and defeat him, sending him careening into the deactivated Nova to obliterate them both and restore peace to the Milky Way. Despite this seeming annihilation, Marx apparently survived and is now a friend of Kirby's (if his appearance as a [[Dream Friend]] in ''Kirby Star Allies'' is to be taken at face value).

In addition to his role in Milky Way Wishes, Marx is also fought as the last boss in [[The Arena]]. In ''Kirby Super Star Ultra'', Marx has a role at the end of [[The True Arena]] mode. Here, it is revealed that, after his defeat at the ending of Milky Way Wishes, Marx's inert body began to absorb errant pieces from Nova as flashes of energy. With this new power, Marx is reincarnated as [[Marx Soul]], the final boss of this mode. Marx also appears on a card in [[Kirby Card Swipe]].

====Battle====
Marx uses a variety of moves in battle. His main ability is teleporting, but he has many other attacks, as detailed below.

Marx has 350 HP.

In ''[[Kirby: Squeak Squad]]'', Marx (True Form) appears in a [[Graphic]] featuring various final bosses from the ''Kirby'' series.

===''Kirby Mass Attack''===
[[File:KMA Minimarx sprite.png|left]]
[[File:KMA Kirby Brawlball Marx.png|thumb|Marx's sprite from [[Kirby Brawlball]].]]
In ''[[Kirby Mass Attack]]'', Marx appears in the sub-game [[Kirby Brawlball]] as the fourth and final boss. He is much bigger than in his previous appearances. His Shooter Cutter and Arrow Arrow attacks serve as objects that can push Kirby down. His Marx Cannon can freeze Kirby for a few seconds if he's caught in it. With his Black Hole attack, he will suck up random enemies, then shoot them out of his mouth. These enemies can't touch Kirby, but he can be sucked by the attack as well, which may cause the player to lose sight of him. His Seed Attack vines appear as obstacles in the field. Copies of his original form, known as the '''Minimarx''',{{DataTitle|1}} also appear in the field. Kirby can defeat him for 100,000 points and two extra Kirby balls, though this can only be done up to five times.

=== ''Kirby's Return to Dream Land'' / ''Kirby's Return to Dream Land Deluxe'' ===
In ''[[Kirby's Return to Dream Land]]'', Marx makes two cameo appearances. One of [[Stone]] Kirby's transformations is of Marx on his ball. Marx proper can also be seen among the audience in the [[Kirby Master]] video.

In ''[[Kirby's Return to Dream Land Deluxe]]'', Marx has two dedicated [[Mask#Kirby's Return to Dream Land Deluxe|Dress-Up Mask]]s - his regular form and [[Marx Soul|Soul form]]. These masks replace the player character's voice with the corresponding laughs from either form. In [[Merry Magoland]], a gold statue of him appears after completing 50 [[Mission (Kirby's Return to Dream Land Deluxe)|missions]], based on his pose in his official artwork from ''[[Kirby Star Allies]]''.

===''Kirby: Triple Deluxe''===
In ''[[Kirby: Triple Deluxe]]'', Marx again appears as a [[Stone]] sculpture, again riding his ball, but this time paired up with [[Magolor]]. He also appears among the audience in the [[Kirby Master]] video. Both Marx and [[Marx Soul]] appear as [[Keychain]]s.

===''Kirby Fighters Deluxe'' & ''Kirby Fighters 2''===
[[File:KF2 Marxs Hat.jpg|thumb|125px|The "Marx's Hat" costume for [[Beam]] Kirby from ''[[Kirby Fighters 2]]'']]
In ''[[Kirby Fighters Deluxe]]'', the [[Beam]] [[Copy Ability|Ability's]] [[Costumes|Rare Outfit]] is made in Marx's likeness. When being worn, Kirby will wear Marx's Hat and a staff with a purple orb. This outfit returns in ''[[Kirby Fighters 2]]''.

===''Kirby: Planet Robobot''===
In ''[[Kirby: Planet Robobot]]'', Marx appears as a [[Sticker (Kirby: Planet Robobot)|sticker]]. The [[Stone]] sculpture featuring him and Magolor together also returns from ''Kirby: Triple Deluxe'', although it is now gray instead of gold.

===''Kirby Star Allies''===

Marx appears as a [[Dream Friend]] in ''[[Kirby Star Allies]]'', added with Version 2.0.0 of the game on March 28th, 2018. His appearance here marks the first time he is playable in the [[Kirby (series)|''Kirby'' series]].

Marx's attack style revolves around his ability to kick jester balls at his opponents and, while flying, use several attacks from his [[boss]] form. He is able to receive [[Power Effect|elemental powers]] from other allies which can further boost his arsenal.

When given a certain element, many of Marx's attacks take on additional effects which are reminiscent of some of his [[boss]] moves in ''Kirby Super Star'' and its remake:
*Using Jester Ball Spit-Drop with Blizzard causes ice shockwaves to spread out after the ball is dropped, resembling 'Ice Ball'.
*Using Jester Ball Spit-Drop with Bluster causes him to shoot out 4 cutters all around himself, resembling '[[Shooter Cutter]]'.
*Using Jester Ball Spit-Drop with Splash causes spiky vines to shoot out of the ground, resembling 'Seed Attack'.
*Using Rush with Zap causes him to shoot numerous lightning arrows forward, resembling 'Arrow Arrow'.

In addition, when Marx performs the [[Team Attack]] with his allies, he has a unique firing pose which resembles the strange expression with which he fires 'Marx Cannon', complete with a unique sound effect.

[[File:KSA HiAD Marx Battle.jpg|thumb|250px|Kirby being attacked by Marx during the surprise boss battle in the credits for [[Heroes in Another Dimension]].]]
Marx also appears as a surprise bonus boss in the Happy Ending credits of [[Heroes in Another Dimension]], where he utilizes all of his moves from the original boss fight. He uses his laugh from ''Kirby Super Star Ultra'', despite the playable Marx using his ''Kirby Super Star'' laugh. If he is not defeated by the time the credits come to a close, he flees. He attacks in a fixed order on loop as follows:
#Shooter Cutter
#Seed Attack
#Shadow Uppercut
#Arrow Arrow
#Ice Ball
#Marx Cannon
#Black Hole

The teleports between each attack are random.

====Cameos====
*Since Version 2.0.0, the [[Stone]] ability can transform into Marx's true form splitting in half.
*Since Version 2.0.0, a hidden stone plate of Marx's true form can be found after activating the Pull [[Switch]] at the end of [[Extra Planet β]].
*Marx appears in three [[Celebration Picture]]s: "Super Ultra Battle", "Crazy Mischief in the Stars", and "Bad Boss Brothers".

===''Super Kirby Clash''===
In ''[[Super Kirby Clash]]'', Marx has two [[Magolor's Shoppe Inventory (Super Kirby Clash)#Gear|gear]] in his likeness. These items are a weapon named "Marx's Staff" and an armor called "Marx's Hat". When paired together, these items are an almost exact match for the Marx's Hat costume from the ''Kirby Fighters'' games. 

Marx also has two [[Sticker (Super Kirby Clash)|stickers]], one on his regular form with the caption "Hey heyyy!", and another on his [[Marx Soul|soul form]] with the caption "Ha-HAAA!".

===''Kirby's Dream Buffet''===
In ''[[Kirby's Dream Buffet]]'', a Marx costume and color palette can be chosen for Kirby once they are unlocked. Additionally, Marx appears as a [[Character Treat]], depicting his artwork from ''Kirby Super Star''.

===''Super Smash Bros. Ultimate''===
{{smashWiki|Marx}}
[[File:SSBU True Form Marx Artwork.png|thumb|225px|Artwork of Marx from ''[[Super Smash Bros. Ultimate]]''.]]
In ''[[Super Smash Bros. Ultimate]]'', Marx retains his role as a boss and his moveset from ''Kirby Super Star'' (except the arrow attack), with three new attacks which can greatly weaken the fighter's [[smashwiki:shield|shield]].

After beating Marx, he bounces on the stage sporadically while screaming before he lands on the floor with his wings separated.

In [[smashwiki:Classic Mode (SSBU)|Classic Mode]], the only characters to fight Marx are [[smashwiki:Kirby (SSBU)|Kirby]], [[smashwiki:Rosalina & Luma (SSBU)|Rosalina & Luma]], [[smashwiki:Inkling (SSBU)|Inkling]], and [[smashwiki:Sephiroth (SSBU)|Sephiroth]].

In [[smashwiki: Adventure Mode: World of Light|Adventure Mode: World of Light]], Marx is one of the three bosses of [[smashwiki:Dharkon|Dharkon]]'s army in [[smashwiki:The Dark Realm|The Dark Realm]], first fought at the end of the [[smashwiki: Mysterious Dimension|Mysterious Dimension]]. Defeating him in the Mysterious Dimension rewards the [[smashwiki:Spirit|Primary Spirit]] of '''Marx''' in his small form (★★ Advanced, Grab-type, 3 slots; Skill: none, attack: 1,001 base, 4,004 max, defense: 587 base, 2,351 max), which can be enhanced into '''Marx (True Form)''' (★★★★ Legend, Grab-type, 3 slots; Skill: Magic Attack ↑, attack: 2,533 base, 6,333 max, defense: 1,654 base, 4,153 max). Later, Marx and the other five bosses of [[smashwiki:Galeem|Galeem]]'s and Dharkon's armies are fought again in a boss rush during the final battle.

Additionally, a hat based on the one Marx wears can be worn by [[smashwiki:Mii Fighter (SSBU)|Mii Fighters]].

According to [[Masahiro Sakurai]] during his "[[smashwiki:Mr. Sakurai Presents|Mr. Sakurai Presents 'Sephiroth']]" video for ''Super Smash Bros. Ultimate'', Marx was initially much creepier than in his final appearance, to the point where he "wasn't suitable for all audiences", so changes had to be made to tone him down.<ref>{{Cite|OK.

==Music==
{{main|Vs. Marx}}
Marx's theme song is his boss battle theme of ''[[Kirby Super Star]]'' and [[Kirby Super Star Ultra|its remake]], '''"Vs. Marx"''' (also titled '''"Meddlesome Marx"'''), and is known for its frequently changing odd time signatures. It has been referenced and remixed many times in ''Kirby'' media, as well as in the ''Super Smash Bros.'' series.

==Trivia==
*The Japanese manual of ''[[Kirby Super Star]]'' describes Marx as a magician (魔法使い).<ref>{{Cite manual|quote=魔法使いのマルクは、ポップスターのそばにある星々をつなげることで大彗星を呼べば解決することを教えてくれました。|language=Japanese|game=Kirby Super Star|page=26}}</ref> In ''[[Super Smash Bros. Ultimate]]'', the [[smashwiki:Spirits (characters)|Spirit]] of Marx (True Form) has the Magic Attack ↑ skill, which possibly references him being a magician.
*The planet Marx is fought on is referred to as [[???]], which is the same name as that of the secret planet (which is where [[Kirby]] gets the [[Copy Essence Deluxe]] of [[Copy]]).
*Marx has no hands, so he uses his hat to grab things like Pull [[Switch]]es in ''[[Kirby Star Allies]]''. However, he does have hands in the ''[[Kirby of the Stars! Moretsu Pupupu Hour!]]'' manga series.
*Some unused data in Marx's boss battle in The Happiest Curtain Call in ''Kirby Star Allies'' includes a health bar and unique music (which is the same music that plays when fighting [[Morpho Knight]] as Marx). This may indicate that Marx was planned as a boss elsewhere in the game at one point.<ref>[https://youtube.com/watch?v=9y-i-TIEKH8 YouTube]</ref>
