Who is Cortez, the Pirate King?
Cortez is an undead: the ghost of a pirate captain whose spirit refuses to leave this world, back as a spectral skeleton. In life as in death, he is said to have terrorized every sea in the game.
That bloody past earned him the nickname Pirate King. Legend has it that he haunts his old lair and curses anyone who dares come near his gold, which eventually drove nearly every sailor away from the region.
You meet him in Chapter 5, on Keelhaul Key (Île Tropatroce in French), a remote tropical island with a reputation for being cursed. That is where Mario lands to get his hands on the fifth Crystal Star.
Because Cortez holds the Sapphire Star, one of the seven Crystal Stars (Gemmes Étoile in French) that the plumber has to gather. The irony: he picked it up without knowing it while plundering a treasure, never once realizing the value of the gem he was guarding.

The hidden treasure of Pirate's Grotto
Cortez's loot lies at the very bottom of Pirate's Grotto, an underground maze carved out beneath Keelhaul Key and riddled with traps, black water and hidden passages.
To carve a path through it, Mario first has to get hold of the Skull Gem (Joyau crâne in French), a relic that works both as a key to open the grotto and as a way to bring the pirate's ship to life.
That gem belongs to Flavio (Marco in the French version), the boastful merchant from Rogueport whose boat carries Mario all the way to the island. His old pirate song even hides the clues needed to solve the grotto's riddle.
At the end of the journey, Mario finally discovers the ghost ship of Cortez and his mound of riches. The pirate appears at once to defend his treasure, triggering one of the longest and most memorable battles of the adventure.

A ghostly battle in three forms
The showdown with Cortez plays out over three successive forms, each with 20 HP: you have to deal 60 HP of damage in total before he finally collapses.
- First form: a giant four-armed skeleton, a weapon in every hand and its torso rooted to the ground, the most visually impressive phase.
- Second form: a serpentine silhouette, a kind of snake-skeleton whose ribcage shelters a vulnerable green gem; paradoxically, this is his weakest form.
- Third form: reduced to a floating head, he animates his weapons as independent enemies and can drain HP from the audience to heal himself, his most dangerous form.
A cruel detail: as long as Mario fails to break his will, the fight ends in a draw, because the pirate's immortal spirit can never be entirely destroyed. Only his surrender puts an end to the battle.

The arsenal: sword, scimitar, rapier and hook
What makes Cortez so distinctive is his four-weapon arsenal, one for each of his skeletal hands: a sword, a cutlass, a rapier and a rusty hook.
His sword combos are multi-hit and form the heart of his offense, quickly eating away at Mario's HP, while his hook has the nasty habit of poisoning its target.
In his third form, those four blades literally break away from him and attack on their own, forcing the player to juggle several threats at once. A true pirate down to the bone.
From dreaded boss to ferrying ally
Once beaten, Cortez realizes that Mario was never after his gold, only the Sapphire Star. A good sport, he hands it over willingly, even admitting he never really liked it.
Thanks to the Skull Gem, Flavio then strikes a deal with the pirate: Cortez agrees to lend Mario a hand and to fight at his side against the X-Nauts landing on the island.
After the chapter, his ship, the Black Skull (Black Scar in France), becomes permanent transport. It shuttles between Rogueport and Keelhaul Key, letting Mario return to the island whenever he likes to dig up treasure and secrets.
A Spanish-flavored name, played up on Switch
Cortez peppers his lines with Spanish expressions, a delicious verbal tic that underlines his theatrical buccaneer identity and gives him an accent all his own.
In the Nintendo Switch remake from 2024, those Hispanic turns of phrase were played up even further than in the original, making the pirate's dialogue more colorful still than in 2004.
His name is no accident: it evokes both the conquistador Hernán Cortés and the Spanish verb "cortar" (to cut), a perfect double nod for a swordsman wielding four blades.
On the release front, the original came out on GameCube on July 22, 2004 (Japan), then on November 12, 2004 in Europe, while the remake landed worldwide on May 23, 2024.
