Gimli and Sam. :) Maybe Legolas too, I Cinta the way Gimli and Legolas interact with each other. Well, atleast in the movies. (Never read the books.) I really like Gandalf [the Grey] too.
My favourite character is Frodo, i like how he keeps goin on even though hes so weak and drained up but he keeps on even if he does keep stumbling inbetween but then sam's there to help him out. i think thats sweet <3 and * ahem ahem * it doesnt hurt that hes reallyyyyyyyy cute too hehe <3
