A few days ago, i came across a thread that discussed about the protagonist of TES 3,4 and 5 that which is the strongest. (Link) There's probably a thread like this exist somewhere on nexus. But I think it's interesting to discuss this in a different way. I'm talking about the canon, post-main quest & official DLCs of the protagonist. That means YOUR character is irrelevant. And so is 100% chameleon exploit(exploits, game bugs in general), titles(Arch-Mage, Gray Fox, etc) , mods and the sort. So here's what I think: (And I'll refer the protagonist as "he" for the sake of simplicity) Nerevarine - First thing first, I have never played Morrowind before so I don't know the details about him. All I know that he is the Reincarnation of Indoril Nerevar(hence his name) and have some sort relationship with Azura, immune to diseases, fought some sort of Daedric prince and possibly became a Werewolf in Bloodmoon DLC. 7th Champion of Cyrodiil - Also known as the 2nd Divine Crusader(Knights of the Nine DLC) and Sheogorath, the Daedric Prince of Madness(Shivering Isles DLC). Being a Divine Crusader easily make him one of the strongest person in Tamriel. And at the same time, he also became a Daedric Prince. Which potentially makes him stronger than Nerevarine(reincarnation of a legend) and/or Dragonborn(body of a mortal, soul of an immortal). Dragonborn - Having a body of a mortal and a soul of a dragon. The ultimate dragon slayer capable of using Dragon Shouts to annihilate his enemies and to slay dragons that were immortal. Slayed lots of dragons and defeated(not slain) Alduin, the Nordic God of Destruction to delay the Elder Scroll's prophecy. He also potentially became a Vampire Lord in the Dawnguard DLC. So yeah, I think the Champion of Cyrodiil is the strongest of the three main characters. Not that I mean that he could easily defeat them. Both Nerevarine and Dragonborn is a demigod in a way. But the Champion is a Daedric Prince! That means something, right? And those are my opinion, now let's hear yours. :P
