In that case, still the Daedric Prince. Even the combined heroes can't bring down a prince. Of course, if we did include the Shivering Isles DLC, the trio would win.

The only team that could have a chance is every single hero (those three and the Ethernal Champion, Hero of Daggerfall, and Vestige), although even then they might still lose.
