While listening to LOTR audio while traveling, I started wondering how many named characters (especially with dialogue) don't yet have cards in the game. So I thought I'd take a systematic approach and look at them chapter by chapter. With one post per day I could get through the entire work in less than two months. I'll put a * symbol by those that have dialogue, and put a bracket around those who are dead/departed by 3001 (year of Bilbo's Party). Names are listed in order of appearance, and cards spoiled but not released are included.
I:1 A Long Expected Party
*Bilbo Baggins (2 saga heroes, Lo Hero, Ta Hero, Sp Ally)
*Frodo Baggins (4 saga heroes, Sp Hero)
[Old Took]
*Ham (Gaffer) Gamgee (Lo Ally)
*Sam Gamgee (Le Hero, Sp Ally)
*Old Noakes
*Daddy Twofoot
[Drogo Baggins]
[Primula Bandybuck]
[Old Master Gorbadoc Brandybuck]
*Sandyman the miller
[Holman Gamgee]
*Gandalf (N hero, two Ne allies)
*Otho Sackville-Baggins
*Lobelia Sackville-Baggins
*Odo Proudfoot
Everard Took
Melilot Brandybuck
*Rory Brandybuck
*Gollum/Smeagol (two objective allies, one objective, three enemies)
Adelard Took
Dora Baggins
Milo Burrows
Angelica Baggins
Hugo Bracegirdle
*Merry Brandybuck (Sp Hero, Ta Hero)
Sancho Proudfoot
Those without cards never left the shire, though I'd like to see Lobelia getting a card for whacking ruffians with her umbrella. Merry needs an ally version, and both Frodo and Sam deserve another hero version.
