The Mighty Elves
 

In your opinion, what do you think would be the order of the most powerful elf to the least powerful elf in the first, second, and third age(seperate list for each age please!)

I'm not sure I can say who was least powerful because all elves have potential power. But disregarding that, it would probably be the youngest elf of whichever age.

To me, Feanor seemed to be the most powerful elf of the first age. He, to me, was probably the most powerful elf in all of Tolkien's works. But I'd also put Fingolfin high on the list.

For the third age, I'd say Galadriel was.

I think it is very hard to list how powerful the different elves was. . . I just don't think that all of their powers are compedable. Elrond's powers, I would say was very differrent from those of say Celembrimbor. . . Non the less I think it would be fun to list them like this, I will make sure to return soon with a list. (I don't have time to make one right now)
