Smaug's dragon-fine would not have been hot enough to destroy the One Ring. The malevolence that Sauron put inside of the Ring could only be destroyed in the Cracks of Doom, so Frodo was compelled to make the journey to Mordor.
In the novel The Lord of the Rings: The Fellowship of the Ring, Gandalf says to Frodo, "It has been said that dragon-fire could melt and consume the Rings of Power, but there is not now any dragon left on earth in which the old fire is hot enough." That is unfortunately true, as, during the War of the Ring, it's ...
He decides to go back down to Smaug and see if he can find his weak spot. Bilbo is invisible because he is wearing his ring, but Smaug can smell him.
By the late Third Age, Gandalf mentioned Ancalagon, noting that not even his fire could harm the One Ring.
Yes, but dragons only seek treasure— not power. So as with the Dwarves, the Ring would have only make him more greedy.
Except for Tom Bombadil, nobody seemed to be immune to the corrupting effects of the One Ring, even powerful beings like Gandalf and Galadriel, who refused to wield it out of the knowledge that they would become like Sauron himself.
Tom Bombadil, the only person unaffected by the power of the One Ring, could both see its wearer and remained visible when he wore it.
Smaug was the last named dragon of Middle-earth. He was slain by Bard, a descendant of Girion, Lord of Dale.
Fingolfin smote the gates of Angband and challenged Morgoth to single combat. Though Morgoth feared Fingolfin (of all the Valar, Morgoth was the only one to know fear), he had to accept the challenge—or face shame in the eyes of his servants.
Isildur took up the hilt-shard of Narsil, Elendil's sword, and cut the One Ring from the hand of Sauron. Despite the urging of Elrond and Círdan, Gil-galad's lieutenants, Isildur did not throw the Ring into the fires of Mount Doom.
The thrush told Bard the Bowman of Smaug's one weak spot, a bare patch on the dragon's belly. With his last arrow, Bard killed Smaug by shooting into this place.
Smaug was considered to be the last "great" dragon of Middle-earth. Sauron allied with Smaug and intended to use the dragon's powers against the people of Middle-earth. But before that could happen, Smaug was slain by Bard the Bowman.
So, one glimpse into Smaug's eyes and the Balrog falls under the spell. Even if it's just for a second—a moment of hesitation or distraction, it'd be enough. Smaug would snatch up Durin's Bane and gobble him up with his sword-sharp teeth (and we know swords can kill Balrogs). There you have it.
Finally, the One Ring, forged by Sauron, allowed the wielder to control the minds of all other ring-bearers. Nearly indestructible, the Ring could only be unmade in the fires of Mount Doom. It virtually corrupted all those who wore it, extending their lifespans and turning them invisible, greedy, and aligned to evil.
Soon after, Aragorn looked into the Palantir and announced himself as the Heir of Elendil. This was a challenge to the Dark Lord, and when Aragorn dared to march on the Black Gate, Sauron was convinced that the Lord of Gondor was wielding the One Ring.
The One Ring is powerful because of its intimate connection to Sauron, the Dark Lord. “The Ring is the Dark Lord, and the Dark Lord is the Ring.” But mastering the Ring's power (and this is critical to the story) takes significant time.
Orome: After the elves awoke it's said that Morgoth “greatly hated and feared the riding of Orome”, but this was mostly because he didn't want the Valar to discover the elves (as evidenced by the fact that his reaction to this is to conspire to turn the elves against Orome.)
In the year I 466, the Iron Crown lost one of its three brilliant Jewels. Through the concealing magic of Lúthien, she and Beren were able to make their way into the throne chamber of Morgoth, and Lúthien placed the Dark Lord into a deep sleep.
Húrin is a fictional character in the Middle-earth legendarium of J. R. R. Tolkien. He is introduced in The Silmarillion as a hero of Men during the First Age, said to be the greatest warrior of both the Edain and all the other Men in Middle-earth.
Drogon Daenerys Targaryen's mount from Game of Thrones, ended up being 50 meters long, plus or minus 10. Smaug from The Hobbit is a staggering 140 meters long, give or take 15.
Smaug is still a huge and devastating beast, especially compared to little Bilbo Baggins, but Balerion's height comes out victorious. However, Smaug was far from the largest Dragon in Middle-earth, as some are said to be as big as a mountain.
Smaug the Magnificent is a dragon – a gigantic flying, fire-breathing reptile into whose lair Bilbo Baggins, the hobbit hero, must venture.
As for Sam, his resistance likely has to do with his innate goodness and loyalty. His love for Frodo helped him to overcome the pull of the Ring and his inner pureness was never fully pierced by the Ring.
The hobbits are perhaps the only creatures in The Lord Of The Rings that can stand against the power of the Ring because of their love of all things good and simple. Not even the elves or wizards are able to fully resist the draw of power or evil.
Though someone could start out with good intentions, the Ring would eventually corrupt them. And that is why Gandalf can't touch it. He is afraid that if he did, it would corrupt him and make him just as bad as Sauron since Sauron put so much of himself and his evil into the One Ring.
