Just had a little theory what is the first Dragonborn will be different depending on race? Paralleled to our character like a Dark Link of a sorts for you Zelda fans whatever we are ranked in say one handed and archery he will be good with so it's like you fight yourself? Food for thought.

Considering you had to fight yourself in Shivering Isles and that he used to be a Dragon Priest who were all Nords last I checked I don't think that will be the case.

Sounds a lot like the original Knights of the Old Republic shocker. Only you didn't fight yourself, you just found out that you yourself were the enemy.

Anyway, I doubt it for reasons WC stated. Besides I don't think Bethesda can be that creative anymore.
