On the eight character-specific Legend of the Guardians: The Owls of Ga'Hoole posters, each character has a different title. Here they are: 

Soren: 'The Leader' 

Eglantine: 'The Dreamer'

Nyra: 'The Evil Queen' (even though she was never a queen in the books)

Kludd: 'The Rival Brother'

Metal Beak: 'The Destroyer'

Gylfie: 'The Navigator'

Twilight: 'The Warrior'

Digger: 'The Tracker'

I have an image of every character poster here. What's your favourite? Mine are Gylfie and Nyra. :) I think having posters for Otulissa and Ezylryb would have been pretty cool as well.
