Controlled by the Yeerks, these aliens are actually peaceful and eventually ally with the heroes in the series, but only after they’re freed. As Yeerk hosts, they should regard themselves as walking weapons and see themselves as superior to others. Later on in the series, they should be able to sound sweet and gentle.

Hork-Bajir have beaks and are six to seven feet tall, but can still talk in a mix of English and alien speech. Feel free to be creative with how you imagine they sound.
