Not too long ago, Death Battle did a match up of these two dark fantasy game protagonists. My knowledge of Chosen Undead is limited to what I've read in comics, and that he does die, but comes back to life. A lot. My knowledge on the Dragonborn is much more expansive. And fully realized Dragonborns in the past, did things like separate Solstheim from the mainland continent, as well as conquer said continent as well (though the ability to use Shouts for him is limited, from what I know). Thus the Dragonborn player gains some game breaking Shouts, to say nothing of the various factions and the skill sets he can spec into (which is all of them). Plus, the Shout cool down is not a lore acccurate thing, its just there to make the game more balanced.
Anyway; spoilers:end of spoilers
Death Battle had the Dragonborrn win, not only by outlasting the Chosen Undead, but with the numerous skill trees, and near countless ways the Dragonborn can end him, while being able to tank or counter almost everything the Chosen Undead can throw at him. Oddly enough, this is one of the few times I've seen almost no one triggered over the results. What do people on here think of this matchup?
