Friendless Sven the Destroyer is a minor character of Bunnicula.
In his human life, he was a large man with a bushy beard.
Until he met Harold, he was only bent on revenge before the latter showed him kindness.
- He is the only ghost in Bunnicula whose current form is unknown, as he only appears embodied in objects (A rubber chicken and an old doll).
- It's unknown if he knows the Ghost Viking Woman and if there is any connection between the two.
