At the end of each Kalpa, Alduin kills every deadra. Including Mehrunes. He kills every Aedra. He kills every mortal and every spirit. He restarts the universe.

In Skyrim, you fought Alduin in his weakest form, because he betrayed his prophecy by attempting a take over. He is not dead, however. Alduin will return in his Kalpa eating form and kill everything again, as he does countless times before.

Alduin is the strongest of all The Elder Scrolls entities. Alduin is not stronger than Akatosh or Lorkhan. They are Anudic and Pandomic incarnate. Alduin represents an aspect of Akatosh, the End and Beginning of Time, and may even consume his physical form, but if one trully tried to destroy the other, Akatosh(the true one anyway) would do so in an instance. Akatosh and Lorkhan are firmly the most powerful of the Tamerilic dieties as they are the only ones who have aspects that can control or use Elder Scrolls. The other gods fear them greatly.
