Who is Booster?
Booster is an eccentric, immature character who rules from the top of Booster Tower, a building he had fitted out like a huge playground, complete with childish rides and a little miniature train to ride around on.
He is never alone: three Snifsters — those black-hooded Snifits — are at his side at all times. They are the ones who explain the world to him, handle the chores and act as his everyday playmates.
Booster behaves like a big spoiled child: he owns a doll collection that he uses to act out and rehearse his whims, and he proves utterly incapable of grasping the simplest emotions of those around him.

A boss who bursts in mid-adventure
When a gigantic sword crashes down on the castle of Bowser, Princess Peach is flung into the air and lands... right on top of Booster Tower.
Convinced that he must marry this stranger fallen from the sky, Booster shuts the princess away on his balcony and stays completely deaf to her cries for help.
Mario and his allies — including Bowser himself — then climb the tower to free her, through traps, a hide-and-seek minigame behind the curtains and one fight after another.
In battle, Booster stays invulnerable as long as his three Snifsters surround him: you have to take them out before you can even lay a finger on him.
He hits back with bombs, one of which deals double damage, and follows up with a signature attack capable of dealing quadruple damage. In the Nintendo Switch remake, he even gains a beefed-up form as a genuine living locomotive, with a colossal total of 3 800 hit points.

The disastrous wedding in Marrymore
With his “fiancée” tucked under his arm, Booster flees his tower and heads straight for Wedding City (Marrymore), the seaside resort devoted to weddings, to make his union official.
Once there, he does not hesitate to throw out the couple who were due to get married there, seizing the chapel and forcing Peach to say yes.
The scene descends into complete nonsense: while Mario struggles to recover the princess's jewels, Booster gets everything mixed up, and a misunderstanding that has become legendary sees Booster and Bowser kiss by mistake in place of the bride and groom.
The comedy comes above all from his total cluelessness: faced with Peach's tears, he does not react to her distress but simply concludes that “it tastes salty”.
The grand finale? His servants bring in a giant living wedding cake — a boss in its own right — which Booster, once the fight is over, calmly devours before heading off, convinced that his wedding has well and truly taken place.
A personality as absurd as it is endearing
Booster is never really looking for love: he treats marriage like a game and a ritual to tick off, without the slightest genuine romantic interest in Peach.
His naivety borders on the absurd: at first he mistakes the princess's cries of distress for joy, and he needs his Snifsters to translate what is going on around him.
The remake adds a delicious touch to his portrait: Booster is apparently permanently in debt because of the outrageous costs of maintaining his tower turned amusement park.
This innocent selfishness, which puts his own pleasure before everything else, makes him less a true villain than a chaotic overgrown child — which explains why he remains one of the game's best-loved characters.
Booster from 1996 to today
Booster makes his debut in Super Mario RPG: Legend of the Seven Stars, released in 1996 (Japan: 9 March 1996; North America: 13 May 1996).
The game was only really (re)discovered in Europe with the Super Mario RPG remake, released on Nintendo Switch on 17 November 2023, which put the character back in the spotlight.
Something notable for a character of Japanese origin: his name stays “Booster” in French as well as in English, whereas other languages renamed him (Borsto in German, Costarugo in Spanish).
One last wink awaits him after the adventure: a suitor named Valentina appears on his balcony, and the ending parade shows him... fleeing his own wedding in a blind panic, true to himself right to the very end.
