Lazy (original French name Schtroumpf Paresseux) is one of the main characters of the Smurfs comic books and the Smurfs cartoon show, who has appeared on the show throughout its entire run.
He is a Smurf who usually wants nothing more but to sleep, which at times causes problems with his fellow Smurfs, though sometimes his habits can prove to be a valuable asset, as in the case in the episode "The Smurfstone Quest", where his echoed snoring protected his fellow Smurfs from being eaten by some underground creatures.
In the Hanna-Barbera cartoon show, he's a relatively quiet Smurf with a very soft voice.
While known for being constantly sleepy, Lazy possesses other traits such as being understanding, friendly, loyal, and mostly mild-mannered.
He is prone to getting agitated when he lacks enough sleep or if he gets rudely awaken from a nap.
In "Never Smurf Off 'Til Tomorrow", after Lazy gets knocked out while attempting to secure the windmill during a hurricane, he and a group of Smurfs get stranded on a volcanic island when the windmill goes airborne. Handy and the others place the blame entirely on Lazy due to the fact they weren't present for his injury, assuming he carelessly fell asleep. When Handy builds a pedal-powered helicopter to escape the island, everyone pedals save for Lazy, who is given a passenger seat. However, when the aftershock of a volcanic eruption renders Handy unconscious, Lazy rushes to his seat in a feat of heroics and starts pedaling, flying the helicopter away from the volcano, only to crash-land in the middle of the ocean. Soon after, Smurfette notices Lazy's hat has an axle grease-covered bump on it along with Handy's, which proves that he hadn't fallen asleep on purpose and is indeed capable of working hard in the face of danger.
In "Paradise Smurfed", Lazy seems to imagine himself as more or so the leader of the trio present in his dream, trying to get Brainy to relax a little and accusing him and Greedy of goofing around and getting into trouble while he's trying to sleep. Similarly, in his dream in "Never Smurf Off 'Til Tomorrow", Lazy imagines himself as a known hero whose intelligence and quick-thinking saves the village from a monster. In the episode, "Lazy's Nightmare", Lazy is finally given the opportunity to be a real hero within the dream world, saving his fellow Smurfs from the evil Morphio.
Lazy is liked by most if not all the Smurfs, regardless of their gripes with his laziness. This is shown by episodes such as "Lazy's Slumber Party", when a bunch of Smurfs throw Lazy a slumber party and only wish for him to have fun, despite his frustration and continued struggle to sleep without one of them waking him up.
He is friends with Smurfs such as Smurfette and Clumsy, who is seen at his house getting ready before attempting to drag him to the Smurf Theatre in "The Golden Smurf Award".
In the movie series
Besides making cameo appearances in Sony Pictures Animation's The Smurfs film series, Lazy also has an appearance in The Smurfs: The Legend Of Smurfy Hollow as one of the contestants of the Smurfberry Harvest contest, although he admittedly collects only one smurfberry. By the end of the story, while Gutsy and Brainy argue over who should get the medal for winning the contest, the medal slips out of their hands and lands looped around Lazy's neck, and thus he was declared the official winner.
