You are able to switch from a dragonborn to a straight dragon  (medium sized ) 

(2 times per long rest)
Natural ac 13
medium size

Breath attack (damage equal to your current breath attack)

Bite attack 1d6 (2d6 at level 3)

Claw attack 1d4 at level 1 (2d4 at level 5)

 You can hold this for for 2 turns per short rest.

You also get resistance to fire too like ancestral resistance 

You breathe pure magical energy into destructive, damaging energy
