Looking back it's interesting how many top choices have since been made.
Going to chose some more unlikely, yet I would love to see made.
1.Don Quixote De La Mancha; a proper figure fully articulated, unique tall lanky body, fully armored, shield, lance , sword and “Helmet of Mambrino" and (if he counts as an accessory; Sancho)
2. Zorro: Either McCulley Pulp version, Fairbanks(bellow), or Disney's Guy Armando Catalano: (metal sword, dagger, whip and flint-lock black-powder pistol a must)
With Pulp era allies: Jose of the Cocopah/Chumash ( Native American) and the Pirate Bardoso (sorry Bernardo they were more significant than you)
(Starting with Zorro a full Fairbanks line)
3. The Shadow pulp version, wide slouch fedora, scarf, large nose, twin revolvers (might be some out there, if so I missed it).
4. Ms. Fury (no not a repurposed Catwoman) the original Marla Drake with panther suit and cape.
5. The Phantom (in Gray), they only made him purple for the sunday color pages, after Superman debuted and got popular.
Yet the original Phantom, the one that started it all, as Lee Falk saw him, was conceived as a gray clad character, all the original descriptions describe a gray suit, he was even called A Gray Ghost.
Accessory (articulated) gray-wolf "Devil".
Similar style but in 1/6 figure form. (in fact I'll take an analogues Golden Age Batman too)
