I’ve been debating this question with a friend of mine for quite a while now. I of course think it’s me, Fingolfin. My friend thinks it’s Hurin. What about you guys?
Here are some worthy candidates:
Fingolfin- Knocked on Morgoths door and challenged him to a duel, mano-on-mano. Crossing the Heleraxe.
Hurin- Valiant stand at the fens of Serech. Killed 70 + Trolls. Survived years of captivity in Angband.
Turin- Slew Glaurung. Probably killed more Orcs than any other man. Walked away from more battles than many long-lived Elven lords had.
Beren- Snuck into Angband and stole a Simiril from Morgoth. Countless other acts of bravery.
Luthien- Defeated Sauron and rescued Beren from Tol-in-Gaurhoth. Helped Beren steal the Simirl from Morgoth. Successfully laid a spell on Morgoth!
Huan- Slew Draugluin (Lord and sire of the werewolves). Defeated Thu(Wolf-Sauron, Sauron in werewolf form). Slew Carcharoth – The Red Maw(Raised by Morgoth himself).
Earendil- Defeated Ancalagon (not to mention his years of voyaging to find Valinor).
Turgon- Founded the city of Gondolin. Led ten thousand warriors to the Nirnaeth. Bravery in the Fall of Gondolin.
Maedros- Endured years of suffering hanging from the peaks of Thangorodrim. [his actions later probably cancel him out there; namely leading to the destruction of Doriath].
Finrod- Founded Minas Tirith. Assisted Beren is stealing the Simiril.
Ecthelion- Single handedly slayed Gothmog, lord of the Balrogs. Kicked everyones ass in combat.
Isildur- Broke into the well-guarded royal palace of Numenor to steal a sapling of the White Tree. The little thing at The Battle of the Last Alliance.
Elendil- He alone withstood the madness of Ar-Pharazon.
Gil-Galad- The only Elven king ever to defeat a Dark Lord.
Aragorn- Actions in before, during, and after The War of the Ring.
Eomer- Greatest Rohirrim ever.
Elrond- Founded Rivendell. Last Alliance. White Council member. Presence in Middle-Earth for over 6500 years.
Gandalf- Too many to name.
Frodo- Destroyed The One Ring.
Sam- See above.
Legolas- Countless acts of bravery.
Gimli- See above.
There are obviously many more worthy candidates. I just don’t have time to name them all.
