The Black Smurfs (original French title Les Schtroumpfs Noirs) is the first album of the original French-language Smurfs comic series created by Belgian artist Peyo, first published in 1963.
Apart from the titular one (which became the basis for the cartoon show episode “The Purple Smurfs”), it contains two other stories: The Flying Smurf (Le Schtroumpf Volant) and The Smurfnapper (Le Voleur de Schtroumpfs).
As most of the Smurfs gather to work on the bridge crossing the river in the forest, Papa Smurf spots one of them dozing off and sends him into the forest to cut some logs. As he works on chopping down his first tree, that Smurf gets stung by a fly known as the Bzz Fly that turns his skin jet black, drives him insane and reduces his vocabulary to the single word “gnap!”
Papa Smurf becomes concerned when that Smurf fails to return and sends another Smurf, Brainy, to go find him. No sooner does Brainy find him, though, that he quickly returns to Papa Smurf, telling him that that Smurf has turned black. Papa Smurf becomes fearful, realizing that that Smurf has been infected by the Bzz fly. Brainy spots the transformed Smurf hopping his way to the village. They chase after him and capture him, binding him in rope. After Papa Smurf tells some of his little Smurfs to take the captured black Smurf to his house, he tells the others that the last known case of this disease was when he was 108 years old, but now he can’t remember what the cure was.
However, the captured black Smurf doesn’t stay bound for long. After breaking his bonds, he spots a normal Smurf outside his house and bites his tail, turning that Smurf black as well. As he watches the two black Smurfs hop into the forest, Papa Smurf sees that he needs to find the antidote. He tells his little Smurfs not to disturb him as he spends the night working on a possible cure for the black Smurfs.
By morning, Papa Smurf send some Smurfs to capture one, though in the process another Smurf gets bitten while trying to capture one, getting caught in his own lasso. This results in some Smurfs capturing the new changed one. Papa Smurf tries his cures on the captive though it fails as it only causes him to faint. It was a mistake, however, to release him, as Papa Smurf sends a Smurf to carry him back to his house, but the Black Smurf wakes up and escapes by biting the Smurf’s tail who in turns infects a bystander.
