Scabior is a snatcher who appears in Harry Potter and the Deathly Hallows. (The book and its two movie adaptations.) He is portrayed in the movies by Nick Moran. He operates as a major antagonist in Deathly Hallows: Part 1.
Scabior became a snatcher during the height of the second wizarding war. He helped catching Muggle-born wizards and people who were against Lord Voldemort, in return for gold. Scabior also helped kidnapping Harry's friend Luna Lovegood from the Hogwarts Express, in that case, they could force Luna's father to hand them Harry Potter.
One day, the snatchers, led by Fenrir Greyback, stumbled upon a tent in which Harry, Ron & Hermione were hiding for the snatchers. Luckily, Hermione was able to change Harry's face so the snatchers won't recognize him.
Still, the snatchers had a feeling that this weird boy was Harry Potter. So, they brought Harry to the Malfoy Manor, home of Lucius Malfoy and his family. They asked for a prize, but were thrown out of the house by Bellatrix Lestrange.
Scabior also joined the Battle of Hogwarts, but died when Neville collapsed the bridge he and other Snatchers were dueling him on.
