If you are a fan of the Super Mario series, you probably know Bowser, the King of the Koopas and Mario’s arch-nemesis.

But did you know that Bowser has a brother? Yes, you read that right.

Bowser’s brother is a real character who appeared in one of the Mario games but was never seen or mentioned again.

Who is he? Where did he come from? And why did Nintendo forget about him?

This article explores the mystery of Bowser’s brother, the blue-coloured version of Bowser that Nintendo left behind.

Bowser Brother Appearance

Bowser’s brother looks almost identical to Bowser, except for his colour scheme.

He has brown skin, a deep cyan shell, and magenta hair.

He also wears a spiked collar and bracelets, like his brother.

Bowser’s brother is slightly smaller than Bowser, but still larger than Mario and Luigi.

He can throw hammers and breathe fire, just like Bowser.

However, unlike Bowser, he is not revealed to be a disguised minion when defeated by fireballs.

This implies that he is a genuine Koopa, and possibly a member of Bowser’s family.


Bowser’s brother made his first and only appearance in Super Mario Bros.: The Lost Levels, the sequel to the original Super Mario Bros. that was released in Japan in 1986.

The game was considered too difficult for Western audiences, so it was not released outside Japan until 1993 when it was included in the Super Mario All-Stars compilation for the SNES.

In the game, Bowser’s brother appears as a recurring boss in several worlds, trying to stop Mario or Luigi from reaching the real Bowser.

He is also the final boss of World 9, a secret world that can only be accessed by completing the game without using warp zones.

In World D-4, a fake version of him appears that is revealed to be a Spiny when hit by fireballs.

Physical Description

Bowser’s brother is a large, bipedal turtle-like creature with a spiked shell, horns, fangs, and claws.

He has a muscular build and a long tail.

His eyes are red and his eyebrows are black.

He has a snout with nostrils and a mouth that can spit fireballs.

He has four fingers on each hand and three toes on each foot.

Bowser’s brother wears a black spiked collar and bracelets that match his shell colour.

He has a tuft of hair on his head that is magenta.

He also has a pair of ears that are hidden by his hair.


Bowser’s brother is a loyal and obedient servant of Bowser, who follows his orders without question.

He is aggressive and hostile towards Mario and Luigi, whom he sees as intruders and enemies.

He is also arrogant and confident in his abilities, as he taunts and challenges the heroes before each battle.

Bowser’s brother is not very smart, however, as he often falls for the same tricks and traps that Mario and Luigi use to defeat him.

He is also easily fooled by disguises, as he mistakes a Spiny for himself in World D-4.

He does not seem to have a name, as he is only referred to as Bowser’s brother or a Bowser impostor.

Bowser’s brother In Super Mario Bros.

Bowser’s brother is not the only blue-coloured version of Bowser that exists in the Super Mario series.

The original Super Mario Bros. had a similar-looking Bowser that appeared in the castle sections before the final boss battle.

However, this was not intentional, but rather a result of the palette used for the castle graphics, which caused Bowser to have a blue colouration.

This was fixed in later versions of the game, where Bowser had his normal colours.

Therefore, this Bowser is not considered to be Bowser’s brother, but rather a graphical glitch.


Bowser’s brother is a mysterious and forgotten character who appeared only once in the Super Mario series.

He is a blue-coloured clone of Bowser that serves as a boss and a decoy for the real Bowser.

He is possibly related to Bowser, but his exact origin and identity are unknown.

Bowser’s brother has not been seen or mentioned since his debut in Super Mario Bros.: The Lost Levels and it is unlikely that he will ever return.

He is one of the many characters that Nintendo created and abandoned, leaving fans to wonder about his fate and significance.
