About the Character
Cocky and charmingly cavalier, Eret has the showmanship of a cowboy and the shady ethics of an arms dealer. His rugged good looks and brawny physique appeals to Ruffnut's inner-most desires--which turn out to be quite shallow. But despite his boastful, brash charisma, Eret lives in endless dread of Drago's merciless wrath, and will do anything to save his own skin.
- Eret is similar in personality to Han Solo, according to Matt Paulson, the modelling supervisor of How To Train Your Dragon 2.
