Alexandros Mograine is quite possibly the most badass, he was THE Ashbringer.

Tirion symbolizes Paladins the best, his character has no equal. Plus, he now wields the Ashbringer.

Turalyon is a great General and has even more lore potential if he makes his come back. Soon, I hope.

Uther, what else can you say about the man. Even in death he is still trying to fight evil.
