The Savager is an extremely aggressive and dangerous dragon species. It was one of the many species that had joined the Dragon Rebellion. Savagers are first mentioned in How to Betray a Dragon's Hero where some were sleeping along a river bank in the Muderous Mountains along with other dragons of the Rebellion.
- "There were Razorwings and Tongue-twisters, Brainpickers and Savagers, some of the scariest dragon species of the dragon rebellion. ... One Savager was gnawing at the ragged remains of a gigantic tree in his sleep, a tree torn violently and entirely out of the ground, its poor tender roots spilled out like a desecration."
- ―How to Betray a Dragon's Hero
- "Even might Rageblasts, or Savagers, or Brainpickers, when hit with those cannonballs, fell shrieking from the sky."
- ―How to Fight a Dragon's Fury
There is no pictorial reference or description of Savagers in the Book Series, but they are mentioned in the Dragon Key in The Complete Book of Dragons. They are classified as Sea Dragons, have "extra-scary teeth", and fought against humans.
