Radagast

"I think he’s a very great wizard, in his own way. He’s a gentle soul who prefers the company of animals to others. He keeps a watchful eye over the vast forest lands to the East, and a good thing too, for always Evil will look to find a foothold in this world.”"

- Gandalf on account of Radagast

Radagast the Brown is a Tolkien character who is a mentioned character in The Hobbit and The Silmarillion, a minor character in The Fellowship of the Ring, a character in Unfinished Tales, and one of the supporting characters of Peter Jackson's The Hobbit film trilogy.

Background
Created with the original name, Aiwendil, meaning “bird friend," Radagast was one of the Istari to go to Middle-earth by the Valar in order to help in the struggle against the Dark Lord, Sauron. He was an associate of Gandalf (then known as Olorin) and when coming to Middle-earth, became friends with Beorn.

Appearance
Radagast is an Istari who is over one-thousand years old. He has pale skin, blue eyes, long brown beard and hair. Radagast wears brown robes and carries around a Wizarding staff

Personality
Most people believed that Radagast was one of the oddest characters in all of Middle-earth. However, he is quite decent, according to Gandalf, he is a very great wizard (albeit in his own way). Saruman once openly mocked Radagast, stating that Radagast's consumption of mushrooms has addled his brain and yellowed his teeth. Gandalf says that Radagast is quite odd but a great wizard nonetheless. However, when Bilbo first saw him, he looked absolutely disturbed when Gandalf pulled a stick insect out of Radagast's mouth.

Radagast was very loyal to the cause in Middle-earth and became a friend of animals, even letting a family of birds live on top of his head. He also is very brave, as Radagast had went out to distract the Wargs and Orcs as Thorin and Company make their escape. He came in Middle-earth’s time of need during the Battle of the Five Armies and even went back to Dol Guldur despite Gandalf telling him to not come back for him.

Possessions

 * His staff: He first takes it when going to investigate why the spiders of Ungoliant invaded Rhosgobel. Radagast uses it to defeat the bats coming after him and to stop the Witch-king of Angmar kills him when in Dol Guldur. It is hardly ever out of Radagast's possession. However, seeing that Gandalf's staff was ruined, Radagast gives him his staff before the grey wizard departs. He told Gandalf that it can be terrible at times.
 * Sled: His preferred form of transportation is a sled made of sticks and pulled by "Rhosgobel Rabbits". The sled is fast enough to outrun a pack of Gundabad Wargs, which were ridden by Orcs under command of Yazneg in the first Hobbit film.

Trivia

 * Along with Azog, Girion, Thrór, and Thráin, Radagast was one of the Five character who was mentioned in the original book to appear in the The Hobbit film trilogy.
 * Galadriel and Saruman and the original characters do not count because they weren't even mentioned in the 1937 novel.
 * Radagast was entirely omitted in the live-action adaptation. Without Radagast's involvement, Gandalfgoes to Isengard of his own accord (because he wanted counsel from Saruman) and is able to escape from the pinnacle of Orthanc by speaking to a moth who sends for the help of the Eagles. thanks
