'''Marx''' ({{ja|マルク|Maruku}}, ''Mark'') is a character from the ''{{uv|Kirby}}'' series, and is the primary antagonist of the {{s|wikirby|Milky Way Wishes}} subgame in ''[[Kirby Super Star]]''. He appears as a [[boss]] in ''[[Super Smash Bros. Ultimate]]''.

Marx made his debut as a major character in the ''[[Kirby Super Star]]'' subgame {{s|wikirby|Milky Way Wishes}}. In the subgame, Marx asks [[Kirby]] to gather the power of surrounding stars to awaken the {{s|wikirby|Galactic Nova}} so the sun and moon can stop fighting. Once Kirby finds and awakes the Galactic Nova, Marx appears and asks it for the ability to rule {{s|wikirby|Popstar}}. The Galactic Nova grants Marx's wish, causing him to become larger and grow crystal wings. After Kirby defeats him, Marx is sent flying into the Galactic Nova, their impact causing them to explode.

In ''{{s|wikirby|Kirby Super Star Ultra}}'', it is revealed that, after Marx's defeat, his body began to absorb the remaining energy from the dead Galactic Nova, which transforms him into {{s|wikirby|Marx Soul}}.

Marx appears as the final boss in ''Super Star''{{'}}s subgame [[wikirby:The Arena#Kirby Super Star/Kirby Super Star Ultra|The Arena]]. In addition to these appearances, Marx appears as the final boss in the ''{{s|wikirby|Kirby Mass Attack}}'' subgame {{s|wikirby|Kirby Brawlball}}, and as a playable character in ''{{s|wikirby|Kirby Star Allies}}''.

In ''Ultimate'', Marx appears as a [[boss]] at the end of {{SSBU|Kirby}}, {{SSBU|Rosalina & Luma}}, and {{SSBU|Inkling}}'s {{SSBU|Classic Mode}} run, as well as in [[Adventure Mode: World of Light]].  His battle takes place in the Mysterious Dimension, which is in the Dark Realm.

Marx's boss fight starts off with him using the moves that he similarly used against Kirby in ''Kirby Super Star'':

* When the fighter gets close, he will teleport some distance away from them.  

* Marx performs the {{s|wikirby|Shooter Cutter}}, sending out four crescent blades from his body that all circle back to him. He may perform this move twice in a row, a reference to when Marx Soul does the attack. The blades can be reflected or eaten.

* Marx moves to the side of the screen to charge up and blast a large Marx Laser.

* Marx floats to the top of the screen and drops a large Ice Ball that explodes into two ice balls that spread out horizontally based on the player's position; they [[freeze]] the player on contact. It can be reflected or eaten. The ice balls can also be absorbed.

* Marx flies offscreen and does a Seed attack, dropping five small seeds that disappear into the ground. Large, thorny, plant-like growths will grow upward from where the seeds landed.  

* A shadow appears on the ground and follows the player. After a bit of time, the shadow doubles in size and Marx flies out of it with a Shadow Uppercut.

* Marx splits in two, opening a Black Hole that will attempt to absorb the player. If the player gets caught, they will take massive damage and get spiked into the ground. Marx often prefaces this attack with multiple teleports from side to side.

However, Marx has moves neither seen in his original game or from his Soul incarnation in ''Kirby Super Star Ultra'':

* Marx's eyes go completely black, then black balls come out of them and start bouncing around the stage, dealing [[darkness]] damage to the player if they hit.

* Marx moves to the middle of the screen and retracts his wings, where pink, branching appendages resembling blood vessels or bronchioles grow out instead, spreading across the screen and dealing [[Flame|fire]] damage to the player.

* Marx grows large compound eyes that send out multiple laser beams from the eyes.

Upon defeat, Marx screams and starts flying around the stage sporadically. His wings break off as he reverts to his smaller form and lands face first on the ground. His body also temporarily alights in a purple flame that simmers out just before the announcer calls game.

In addition to his boss appearance, Marx appears in the game as a [[spirits (characters)|spirit]] in both of his normal and true forms, while his boss theme from ''Brawl'' returns as a music track. His hat is available for the Mii Fighters in the shop.

*Marx is the only boss to be fought in Adventure Mode that does not have an area themed after his game of origin. His area appears to be a destroyed variant of various locales in the World of Light, as opposed to Pop Star's moon, on which he is fought in ''Kirby Super Star''.

*Marx is one of three bosses who hasn’t appeared in previous smash games. The other two are Dracula and Rathalos.

** Marx is the only one who is Nintendo, as the Dracula and Rathalos were made by Konami and Capcom respectively.
