Hackus

As a Naughty, he is rather dimwitted, speaking only in simple sentences which sometimes include his name. When he is transformed into a Smurf, he becomes much more loving and caring to his new friends and family.

He is a Naughty created by Gargamel in order to trick Wonder Smurfette into being naughty, claiming that being naughty was fun. He, along with his partner Vexy show Wonder that being naughty is fun when they cause all sorts of trouble in nearby villages and annoying the townspeople. They eventually cause Wonder to act just like them. However, when he and Vexy became Smurfs, Gargamel immediately placed them, along with Wonder into his Smurfalator, located under his hovel, in order to extract their essence (When actually he is only doing it as a distraction). Eventually, they were rescued by Johan, Peewit, Princess Savina and the Smurfs before any major damage could be done to them, and they teamed up with the Smurfs against their former master.

He has grey colored skin, a grey Smurf hat and pants, he has orange hair on the sides of his face which resemble dreadlocks, and he also has an orange goatee. When he becomes a Smurf, his attire stays the same, but his skin becomes blue.
