Polari is an elderly dark brown Luma who appears during the events of 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.
Polari shows certain similarities to Toadsworth. Both are probably the oldest of their respective species, both are highly protective of the person they advise, and both have a brownish color which is unusual if compared to others of their species. He is additionally shown to have wisdom that proves useful to Mario on his adventure such as telling Mario about the Trial Galaxies.
Like all Lumas, Polari loves Star Bits and may thank the player if they shoot a Star Bit at him.
 Super Mario Galaxy
Polari's only appearance was 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.
