I couldn't tell you exactly why Marx is so important to me. He's just always been here.

When I was young, I would create my own physical marx-es out of paper or with my poorly needle-felting skills. I wish it had been earlier, but you can imagine how excited I was when the first official marx plush released in 2017. Since then, I have collected many pieces of Marx merch, and run a website dedicated to archiving marx merchandise.

I am also fascinated by his relationship with Magolor, which is best summed up by Tumblr user dinoburger as "the most non-canon canon relationship in existence". Wikirby also describes them as "associated in various external media for the franchise". It's really funny how we're like "They probably know each other? Also they are for sure dating".

In-game major appearances:

• Kirby Super Star: Final boss of "Milkyway Wishes" mode
• Kirby Super Star Ultra: Same as above, as well as the final boss of The True Arena as Marx Soul
• Kirby Star Allies: Playable ally
• Super Smash Bros. Ultimate: Boss

In-game minor appearances:

• Kirby Squeak Squad: png
• Kirby Mass Attack: Final boss in the pinball mini-game!
• Kirby's Return to Dreamland: STONE. and cameo in the 100% cutscene :)
• Kirby Triple Deluxe: STONE. (Now with Magolor)
• Kirby Planet Robobot: STONE. And a sticker! Yay!
• Kirby Fighters Deluxe & Kirby Fighters 2: Magolor sells an outfit and weapon based on him. These are also in Super Kirby Clash.
• Kirby's Dream Buffet: Costume and color palette. Notably, the color is called "Marx Lilac", finally putting an end to the debate over wether he is purple or pink.
shit nevermind
• Kirby's Return to Dreamland DX: MASK. Creepy...

???:

• Kirby's Return to Dreamland:Magolor says this, which could be in refrence to Marx:

"I even know somebody who knows you quite well!" "Even on this world, you're incredibly popular!" "There may even be some folks here who have fought with you before."
