Silent Sven, later known as Not So Silent Sven, is an aparantly mute Viking sheperd on Berk.
Not much is known about this viking, but he seems serious and grumpy and dislikes it when people mess with his sheep and think he's deaf. And he also seems to have no tolerance for disobedience from his sheep and cared deeply for his prized black sheep.
In Defenders of Berk
Silent Sven's chest hairs were then burned during a Screaming Death practice drill. Silent Sven fought off the Frozen Skrill when he tried to eat his sheep herd with his head. Sven then broke his silence to complain to Stoick the Vast about something in berk.
After he broke his silence, Sven's new voice scared the sheep out of the pen.
- Despite appearing in Viking for Hire, he was left unnamed until A View to a Skrill Part I.
- His nickname might be a reference to the fact he is usually just a background character with no lines.
- He shares the same name as another resident of Berk, who is voiced by Brook Chamlers.
