Brainy Smurf

Brainy Smurf (original French name Schtroumpf à Lunettes) is one of the four main characters of the The Smurfs franchise.

Official Website description
Brainy Smurf thinks he’s smarter than he really is, and he is certain that he’s smarter than everyone else. This is a Smurf who does not suffer from self-doubt. Brainy considers himself the most responsible member of the band and has proclaimed himself the right-hand man to Papa Smurf. He loves to talk, and he is often repeating phrases such as, Like Papa Smurf always says… or Papa Smurf is always right, and when he says that… The other Smurfs just roll their eyes and find inventive ways to shut him up.

Character
Brainy Smurf is the village intellectual who's not afraid of claiming that he knows everything and everyone, as well as his "knowledge" related to Papa Smurf, even though it results in almost all of the Smurfs getting annoyed with him and is ignored and/or silenced in more ways than one - such as being clobbered in the head with a blunt object (usually a mallet) or being booted out of the village (occasionally towards a further distance from the other Smurfs).

Exclusively, in the 1981 television series, Brainy Smurf is often the root cause of chaos within the village. While he is knowledgeable when it comes to magic and potion-making, Brainy often over-estimates himself, or doesn't clearly follow directions, which can cause problems for both himself and other Smurfs.

Due to being a major nuisance towards the other Smurfs, Brainy appears to have no known "Best Smurf Friend" in the comics and 2021 television series. Though exclusively in the 1981 television series, his best friend, and the only Smurf who enjoyed Brainy's company, was Clumsy Smurf. Upon first glance, his friendship is one-sided, as Brainy generally sees Clumsy as an annoyance. While he sees Clumsy as a frustration, there are some episodes where he gets along with him perfectly fine such as "The Gingerbread Smurfs" and "Dreamy's Pen Pals", and has expressed deep concern about Clumsy getting hurt in "The Chief Record Smurf" or missing in "The Pussywillow Pixies".

Motive
In the 1981 television series and 2021 television series, Brainy serves as Papa Smurf's apprentice or assistant in his laboratory, and once referred to be Papa Smurf's "self-appointed" right-hand man in "Born Rotten". He will often police other Smurfs doing their jobs or chores as if he is their guide, though it is incredibly rare it actually helps.

Physical appearance
He is easily identified with is identified by his ordinary white Smurf hat, pants, his glasses and his encyclopedia books.

Between the release of "Little Comics Collection" version of "The Hundredth Smurf" and before the album release of "The Black Smurfs", the only thing that visually separates Brainy from the other Smurfs is his tendency to use his declarative finger when he makes speeches.
