After rescuing them, Tom gives each Hobbit a long dagger taken from the treasure in the barrow. He refuses to pass the borders of his own land, but he directs them to the Prancing Pony Inn at Bree.
The Barrow-blades were weapons that Tom Bombadil brought out of the mound in which Frodo Baggins and his friends had been imprisoned. Each Barrow-blade had a long, leaf-shaped blade, damasked with serpent-forms in red and gold.
It seems odd that he is supposedly such a powerful and ancient creature, but the only impact he has in the larger story is linking Merry up with the dagger from the Barrow Downs that he used to stab the witch king (which is obviously important, but could have happened without introducing Bombadil.
Perhaps the most far-fetched theory yet states that Tom is not really the jolly old being we see, but in fact, something eviler, and much more powerful, than Sauron and many other characters.
Understanding the mystery, however, does require at least comprehending what we can. As Johnston summarizes: What we know about Bombadil is that he is a powerful and ancient being, older than Gandalf and older than the elves, and he has no interest in “trinkets” that are used to dominate others.
Gandalf says, in response to Frodo's query of how well Bombadil is getting along, that Bombadil is "as well as ever", "quite untroubled" and "not much interested in anything that we have done and seen", save their visits to the Ents.
The most common theory is, therefore, that Bombadil is just a "rogue" Maia who perhaps stayed behind and did not follow the other Ainur at the Breaking of the World. In contrast to the seven Valar, the Maiar are an unknown number, so it's easy to associate Tom with them.
Some have theorized that Bombadil was a member of the Istari, powerful angelic beings, but his behavior and choices also make that idea unlikely. Other readers wonder if Bombadil might have been one of the Ainur. Ainur are best understood as descendants of the gods and consist of Valar and Maiar.
It is often thought that his mysterious origin may tie back to the Ainur, the angelic creatures who had a hand in creating Middle-earth itself. Using softer, gentler sources such as music and the surrounding forest, Bombadil could perform great magic to seemingly control the world, reality and nature around him.
It doesn't say anywhere that the Ring tried to possess Tom Bombadil and that he resisted. The Ring simply has no effect on Tom, and that's probably because Tom is a being out of space and time. He is a complete anomaly as well as an incongruity. The laws of Middle-earth almost don't apply to him.
But there's actually a long-standing fan theory of the original books, which, if true, quietly means Tom Bombadil was in the movies all along — in his true form as the Witch-king of the Nazgûl. The twist seems outlandish, especially considering Bombadil's overtly benevolent nature in Tolkien's work.
The Ring cannot effect Tom Bombadil because he is outside the whole issue of Power and Domination; Tolkien uses Tom as an allegory that even this intense struggle between "good and evil" is only part of the whole picture of existence. On this page you can find everything about the Rings of Power.
Peter Jackson did not include Tom Bombadil in his Lord of the Rings films because he felt that having a character who was so immune to the Ring's powers would cause the audience to not see the Ring as dangerous as it was.
For one thing, Gandalf tells us there are only five wizards in Middle Earth: the Brown Wizard, Radagast, who is definitely not Tom; Saruman the White who shows up elsewhere in Lord of the Rings; the two Blue Wizards, Alatar and Pallando, who went into the east and have not been heard from again; and, of course, Gandalf ...
Tom Bombadil's strength lies not in physical prowess but in his unwavering goodness and connection to nature. He is a creature of immense antiquity, predating even the likes of Sauron. His power is unobtrusive, but it distinguishes Tolkien's understanding of strength versus might.
As only The Hobbit, The Lord of the Rings, The Adventures of Tom Bombadil, and The Road Goes Ever On were published during Tolkien's lifetime, some argue only those works should be considered "true" canon with respect to Tolkien's publication history.
Proclaimed to be "the oldest in existence," Tom Bombadil was apparently immortal and possesses a range of enigmatic powers able to give full control over his domains, seen by Goldberry that described Tom as being "Master of wood, water and hill". He was also referenced as being impossible to capture or imprison.
Since Bombadil wears a blue coat and little is known about the movements of the blue wizards, some fans speculate that he could be one of these absent sorcerers in disguise, though this is highly unlikely due to Tom residing in Middle-earth long before the wizards arrived.
Tom Bombadil, Tom Bombadillo! By water, wood and hill, by the reed and willow, By fire, sun and moon, harken now and hear us! Come, Tom Bombadil, for our need is near us!
Perhaps Tom Bombadil was not really alive, but rather a spirit. Some Tolkien fans speculate that Tom Bombadil was in fact a Maia or even a Vala who had originated in the Far West. Tom was a being of intense age; he had been in Middle-Earth before the trees and the rivers.
Given these bits of information, it seems like within his realm, Bombadil would have been able to defeat the Nazgûl or at least banish them. Outside his realm, however, he wouldn't have been quite as effective in a fight against them.
She also resisted being offered the ring of power by Frodo following his vision in the mirror of Galadriel, an immense test given the ring's seductive powers. Yet Gandalf's power level exceeds even that of Galadriel, as shown by his rebirth in the Two Towers.
