Ents are arguably the strongest race in terms of physical power. They are said to be able to bend steel and stone as if it is paper, and their attack on Isengard in The Two Towers shows them to be an unstoppable force.
Hobbits are one of the weakest races in the LOTR universe. Most could be defeated by simply ruining their lunch. Hobbits are charming and valuable people but they aren't a very strong race.
God is the most powerful entity in Tolkien's Lord of the Rings universe. The Elvish name for him is actually Eru Ilúvatar, meaning “the one, father of all.” So the question becomes: Who is the second-most powerful being? Originally, it was Melkor, “he who arises in might,” the most powerful of the Ainur (or angels).
The longest living Dwarf was Dwalin who lived to become 340 years old, 80 years older than the second oldest Dwarf. Hobbits lived a very quiet and uneventful life compared to other races and since they had the habit of drawing their family tree their age distribution is fairly narrow.
Tom Bombadil is the oldest, as are other Maiar and Varda listed above. The Ents came from the thoughts of Yvanna (a Varda), who is the same age as Tom Bombadil. Also, the Ents were not resistant to Saruman's evil, but Tom Bombadil was unaffected by Sauron's evil ring.
In J. R. R. Tolkien's writings, Elves are the first fictional race to appear in Middle-earth. Unlike Men and Dwarves, Elves are immortal.
Tulkas Was the Strongest Valar
Most LOTR fans would assume that Morgoth was the strongest Valar, and they wouldn't be far off. The Silmarillion did say that he was the "most powerful" of the Ainur.
Morgoth Was Originally More Powerful Than Sauron
In the depths of time, Eru Ilúvatar created Arda and the Valar. He made the Valar to help create and order the world, but the most powerful Valar, Melkor, turned out to be nothing but problems.
In Tolkien's Middle-earth the Elves were generally stronger and faster than the Orcs; the Orcs usually only won through deceit and weight of numbers. So in this respect the “Hobbit” movies (and the “Lord of the Rings” films) are probably being faithful to Tolkien's idea of the comparative strengths of Elves and Orcs.
Uruk-Hai. Lurtz was the first and one of the strongest orcs known as the Uruk-Hai that were created by Saruman the White. He led a party of Uruk-Hai to Amon Hen, where they intercepted the Fellowship of the Ring and tried to capture Frodo.
Unless you are not well-versed in your pop culture, you know Sauron is the main villain in JRR Tolkien's 'The Lord of the Rings' and Peter Jackson's trilogy in the book. Sauron, briefly, appears in 'The Hobbit' trilogy as well. Sauron is one of the most well-known villains in pop culture.
Traditionally, many character races in D&D have been defined to have a race with whom they share a mutual hatred: elves and orcs, dwarves and goblins, and gnomes and kobolds, for example.
Sauron. The Dark Lord Sauron is the most powerful villain in Middle-earth. He is a Maia, one of the divine spirits who entered the world to aid the Valar in their work. Sauron is responsible for creating the One Ring, which grants him immense power and the ability to control others.
A powerful and bruising fighter, Dwalin has a natural tendency to distrust anyone who is not a Dwarf and is particularly suspicious of Elves. Proud, brave and one of the tallest of the Dwarves, Dwalin will bow to none but those who have earned his respect.
His prowess with a bow was unmatched among the Fellowship and, as J.R.R. Tolkien stated himself, Legolas was “endowed with the tremendous vitality of Elvish bodies,” as well as an inability to feel terrible hurts, which made it easy for him to travel long distances over rough terrain in only light shoes.
Especially in Tolkien's The Lord of the Rings, orcs appear as a brutish, aggressive, ugly, and malevolent race of monsters, contrasting with the benevolent Elves. They are a corrupted race of elves, either bred that way by Morgoth, or turned savage in that manner, according to the Silmarillion.
In The Lord of the Rings, it is said that had Galadriel chosen to use her powers for evil instead of good, she would have been even more destructive and terrifying than Sauron himself. Galadriel was the greatest and most powerful of all Elves in Middle Earth in the Third Age.
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.
Telchar was one of the greatest smiths of the First Age of Middle-earth, having learned from Gamil Zirak the old. Telchar was commonly regarded amongst the greatest smiths of all time, save only Fëanor and Celebrimbor.
Galadriel. One of the elves who lived in Middle Earth the longest was The Lady of Lothlorien, who arrived in the First Age and left in the Fourth. Galadriel's enigmatic abilities were tremendous, having learned magic from Valar and Maiar. All Middle Earth's races feared her, including men, dwarves, and Sauron's army.
At that time, Círdan would abandon the Grey Havens and finally travel the Straight Road himself. On some unknown date, he sailed west aboard the Last Ship with his mighty kinsman Celeborn, but when he did so, he took with him the last living memory of the Elder Days in Middle-earth.
Who is Legolas? Legolas is a Sindarin Elf from the Woodland Realm of Northern Mirkwood. His father, Thranduil, is the King of the Silvan Elves living in that realm, making Legolas the Prince of Mirkwood.
