Alduin is back, but it’s time for him to go up against Bass! Bass has his Darkness Overload attack and Alduin simply won’t be able to stack up against him. Bass has speed that is simply unparalleled and Alduin would be defeated before the match ever got a chance to truly begin. That is the difference in their power! Bass wins.

Lololol. Bass has no Dragonrend so Alduin stomps him. Nice try but fail.
ALduin’s just a dragon…he gets massively speedblitzed all day. He wouldn’t land a single hit.
Unless Bass has Dragonrend, Bass can’t do anything to Alduin
Darkness Overload>>>Dragonrend so Bass has still got this round.
Prove it or else you’re just wanking Bass’ abilities. Dragonrend is one of the things that effectively removes Alduin’s invulnerability and immortality for a bit though Akatosh or one of the other divines or Anu the big god of Skyrim himself may override that invulnerability.
Oh, that’s easy my friend.
If you don’t want to see Bass cross doing it, then here’s normal Bass using the move.
