Miraak was the biggest wimp in all off skyrim, he got his ass kicked by a follow dragon priest who then took his mask his knife and his staff and locked him up in his own temple. And the only way he could kill dragons was to use the bend will shout on them so they wouldn't fight back.
And all his powers he got given to him by Hermaeus Mora ,who also had to give him armour and a sword as well because he was not man enough to get his own. he mite have been the first dragonborn but that does not make him a Darth vader badass type.
I beat him like a drum, i pounder on him hard and I made him scream like a little girl.
