Polari

"Would you like to see the map? Here you go."

- Polari

Polari is an elderly blackish brown Luma who appears in Super Mario Galaxy. Said to be one of the oldest Lumas in existence, Polari serves as Rosalina's most trusted advisor. Having extensive knowledge of the Comet Observatory, Polari serves as a guide of sorts to Mario, showing him a map of all of the galaxies visible from that location.

While Polari's name is never mentioned in-game, and is instead mentioned only in the instruction manual, his name may be derived from "," also known as the North Star. Polaris was often used by sailors as a guide in navigation, not unlike how Polari advises Rosalina and guides Mario. Conversely, his appearance may be a reference to s, which are dead stars.

Super Mario Galaxy
Polari's first appearance is in Super Mario Galaxy when Mario retrieves the first Grand Star and lands on the Comet Observatory. Polari looks at the beacon with Rosalina and exclaims that "now the poor Lumas may survive". When the player first enters the Terrace they will meet Polari and a Blue Luma that soon transforms into a Pull Star to allow Mario to travel to galaxies. When Mario returns with one Power Star on his belt, Polari will teach him about Star Bits and how Lumas love eating them. Other than that, Polari's main importance within the game is to provide a map of all the galaxies that Mario can visit and their Power Stars and to inform Mario about when the enemy base has been located.

It is unknown what happens to Polari at the end of the game; he is not seen flying into the giant black hole, and in the secret ending, he does not appear alongside Rosalina or in the Comet Observatory at all.

Super Mario-kun
Polari also appears in the Super Mario-kun manga's Super Mario Galaxy arc (volumes 38–40). Compared to his appearance in Super Mario Galaxy, his age is much more apparent because of his wrinkles. In volume 40, he grows into the final Grand Star, in contrast to his navigator role in Super Mario Galaxy.

Mario Golf: World Tour
Polari makes a cameo appearance in Mario Golf: World Tour in Rosalina's best post-hole animations.

Super Smash Bros. series
In Super Smash Bros. for Nintendo 3DS, Super Smash Bros. for Wii U, and Super Smash Bros. Ultimate, when Rosalina re-spawns a Luma, there is a chance for Polari to appear. Although the tips in the latter two games confirm that it is Polari (referring to him by name in-game for the first time), he shares the same voice clips with the other playable Lumas instead of reusing his voice clips from Super Mario Galaxy.

Mario Sports Superstars
Polari appears in Mario Sports Superstars, where he fulfills the same role he has in Mario Golf: World Tour.

Physical appearance
Polari, unlike all other known Lumas, is a blackish brown color and has sky blue eyes. Aside from this unique coloration, he is relatively the same size as all other Lumas, excluding the larger ones like Hungry Lumas, Lumalee and Comet Tico.

Characteristics
Polari shows certain similarities to Toadsworth: both are older members of their respective species, they are highly protective of the person they advise, and they have a coloration that noticeably deviates from the typical color schemes of their respective species. Polari is also shown to be wise, with his knowledge proving useful to Mario on his adventure, such as telling Mario information about the galaxies in each of the domes.

Just like all other Lumas, Polari loves to consume Star Bits, and he may thank the player if they shoot a Star Bit at him. Compared to the Lumas and the joyful sound that they emit when happy or excited (such as when they consume Star Bits), Polari's voice is deeper and he emits a distinctly different sound upon consuming Star Bits.

Super Mario Galaxy

 * Bios
 * Instruction manual: This elderly Luma is Rosalina's most trusted advisor. He knows all about the observatory, and if you speak to him, he will show you a map.
 * Trading card: An elderly black Luma that is one of Rosalina's most trusted advisors. Polari serves as Mario's guide to the cosmos from the domes on the Comet Observatory. Polari will show Mario a map of the galaxy showing where he's collected so far.

Trivia

 * When Mario first lands on the Comet Observatory, Polari does not accept Star Bits, and any Star Bit flung at him by the cursor will simply bounce off Polari.
 * Polari accepts them once Mario enters the Terrace for the first time, but he stays silent and does not give one of his usual responses like, "Yummy!" Polari can be fed with Star Bits normally once Mario collects the Power Star from Dino Piranha.
