This article page is about Bryoscar in Sanctuary. For real-world folklore/mythology, see Wikipedia:Troll.
Bryoscar are a troll race of humanoid abnormals. They are large, muscular creatures, about two meters tall, with huge clawed hands and spikes growing out of their back. The skin is greyish, with some fur growing around the neck.
Episode 2x02 - "End of Nights, Part II": A troll defended the London Sanctuary against an attack by four of the Cabal's super abnormals. Although it proved to be a formidable warrior, it was quickly overwhelmed and killed by Ashley Magnus, who snapped its neck with her vampiric claws.
Episode 3x20 - "Into the Black": At least one troll was among the abnormals from Hollow Earth who started coming to the surface in late 2010; it was identified by Kate Freelander to the Lotus Defense Corps as a Bryoscar, to whom water is toxic.
Trivia: Although this species of abnormal was first seen in the second half of the season 2 premiere Episode 2x02 - "End of Nights, Part II", it remained unnamed until the finale episode of season 3 Episode 3x20 - "Into the Black".
