You could go the fem way and call your beardie "Hercup" lol or i was reminded of the name of the princess in the movie The Princess Bride - "Buttercup"
Well if you like saphira (from the inheritance cycle) i think you may like Glaedr. I know that is still a boy dragons name but since your beardie is missing some toes thematically it fits just an idea otherwise i like saphira
