Radagast appears in The Lord of the Rings: War in the North, where he flees from his home in Rhosgobel during the War of the Ring to one of his hideaways in Mirkwood. There Radagast is captured by the spider Saenathra, at the behest of Agandaûr. Radagast is later freed by Eradan, Farin and Andriel, who kill Saenathra.
It's there Saruman does him in. Gandalf describes Radagast as "a worthy wizard" and that "it would have been useless in any case to try and win over the honest Radagast to treachery." Therefore, Saruman removes Radagast as a possible adversary against him rather easily at Isengard, and he's never heard from again.
His fate is unknown. It's speculated that he failed in his mission, because he was more interested in tending to plants and animals than to opposing Sauron. The problem with this idea is that, as a maia of Yavanna, he would have been more inclined to protect Nature rather than be an active opponent of Sauron.
But Radagast was weaker and his role overshadowed by Gandalf's achievements. Therefore it is difficult to conclude whether or not Radagast failed. But it is clear that Tolkien had doubts following his criticism of him in the Istari essay and Radagast certainly did not fall into evil.
Radagast the Brown is a fictional character in J. R. R. Tolkien's legendarium. A wizard and associate of Gandalf, he appears briefly in The Hobbit, The Lord of the Rings, The Silmarillion, and Unfinished Tales.
Tom Bombadil is an incarnation of Arda, or perhaps a steward of Arda, or of Middle Earth. He's a "Mother Earth ... Did radagast become GREY? Tolkien initially called him "Radagast the Grey", but in pencil he changed this to "Brown" and subsequently Saruman refers to him as "Radagast the Brown".
As one of the most powerful beings in The Lord of the Rings, Radagast the Brown is one of the five wizards who came to Middle-earth on a mission to oppose Sauron and was a friend of Gandalf in the series.
It is unknown if Radagast left Middle-earth. J.R.R. Tolkien wrote that he forsook his mission as one of the Wizards by becoming too obsessed with animals and plants, so presumably failing, perhaps being disallowed to return to Valinor with honour.
The Blue Wizards Arrived First
The first Istari sent to Middle-earth to fight against Sauron are the two blue wizards named Alatar and Pallando. Alatar had been chosen by the Valar Orome, the hunter. Alatar didn't want to go alone, though, so he asked his friend Pallando to join him.
Meet Radagast! Although our Radagast can't turn into a bear but J.R.R Tolkien would still be proud of this big lug! Radagast would walk best on a harness and needs some training classes to show him the ropes of how to be the best boy!
Together, the two of them were known as the Blue Wizards. The one in brown was Radagast and the one in grey was Gandalf, seemingly the oldest and the least of the Order.
Originally a Maia of Yavanna, Radagast was mainly concerned with the well-being of the plant and animal worlds, and thus did not participate heavily in the War of the Ring. He is eighth most powerful of all the Maiar.
Radagast the Brown is one of five wizards that came from the Undying Lands to Middle Earth.
Saruman was less angry with Radagast and more contemptuous of him. In Saruman's view, Radagast was little more than some hedge witch; too concerned with feeding birds and living in some forest hovel, as opposed to a majestic, wise figure and master of magic like Saruman.
The difference is that Radagast was more concerned with the birds and beasts of Middle-Earth, while Gandalf focused on inspiring the people. There are no statements that say “Gandalf was more powerful than Radagast”, if that's what you're asking. Such statements are rare in Tolkien's works.
It is said they travelled into the East with Curunír but they did not return into the West. Their fate was unknown, but some held that they fell into evil and became servants of Sauron.
In the film adaptation, however, Gandalf mentions the Blue Wizards but claims he doesn't remember their names. This is actually due to a copyright issue because the names of the Blue Wizards don't appear in the trilogy. In hindsight, another good reason was that maybe adding Radagast into the story was enough.
Why didn't he? He had been through Moria (more than once), but if memory serves he had only gone East to West, never West to East. So when he came to this place before, he may not have realized it was a fork in the road as he was coming out if the fork, not into the fork.
While Gandalf does reference the Blue Wizards during his travel with Bilbo Baggins and Thorin's company of dwarves, the studio didn't actually have the rights to Tolkien's Unfinished Tales of Númenor and Middle-earth and The Peoples of Middle-earth, where the Blue Wizards are featured, resulting in their absence from ...
Radagast decides to use his magic on Sebastian, and when he finishes his incantation of the spell, the spiders return to the place from whence they came. Meanwhile, the spell has cured Sebastian, and he appears completely back to normal.
Despite Radagast finally getting involved in the fight against Sauron, it didn't last long, as by the time of The Lord of the Rings, he was nowhere to be found. After the formation of the Fellowship, Elrond sent out scouts to search for the Wizard, but he was never located.
He avoided returning to Valinor because he didn't want to have to face punishment. So, even after the Ring is destroyed he wanders around powerlessly because he doesn't feel the other ainur have the right to judge him.
Though Albus Dumbledore eventually defeated him, Grindelwald's legacy continues to live. Lord Voldemort is one of the most feared and powerful wizards. He is known for his cunning and ruthlessness.
