Daggerfangs

The Daggerfangs are a Chaos Warband comprised of Chaos Space Marines from the Alpha Legion Traitor Legion. Led by Chaos Lord Vykus Skayle, the Daggerfangs are unlike other Alpha Legion warbands, as they are faithful devotees of the Ruinous Powers.

Warband Colours
Like the rest of their parent Traitor Legion, Daggerfangs still maintain the basic Alpha Legion colour scheme for their Power Armour -- blue, silver and green.

Warband Badge
The Daggerfangs uses the same Legion badge and iconography as the rest of the Alpha Legion, namely a green hydra, the mythological multi-headed serpent that has the ability to grow back two heads for every one that was cut off.
