Lachlan Haines
Lachlan came from a messed-up beaver family that had no idea what they were doing. He had a weird mix of DNA and thought his teeth could fight fire. He carved a mountain with his mouth, but he still managed to be the most idiotic person who ever lived. He saved the world, but only because he was too dumb to die.
He bit a mountain so hard he got a toothache and a headache.
He tried to take down the fire nation with a stick and a dream.
He saved the world, but then forgot what he did.
