Boba Yaga – Let’s get another powerful,scary witch to replace Cora.
Shakespeare characters – I would like to see OUAT incorporate mystical characters from Shakespeare like they did brilliantly on Disney’s Gargoyles with characters like Puck, Macbeth, and the three witches
Elizabeth Bathory – The legends surrounding her are even more interesting than Dracula. She might be too dark a character for OUAT to take on though
Scrooge – from a Christmas Carol
A succubus!
ATLANTIS! – I’d take that over the little mermaid
Death – or some sort of grim reaper character http://www.youtube.com/watch?v=AyNge7RF_lA
I’d love to see a fully animated, 2d land with a character like Giselle from Disney’s Enchanted. Hey, if they can do a black and white version of our world with Frankenstein, why not? Fringe has had a fully animated episode, and Angel had an entire episode with Angel as a Jim Henson-like puppet.
I’d like to see OUAT do a take on old Saint Nick, right around December
As someone else said, I’d like to see Snow’s long lost sister, Rose Red.
Another vote for Cheshire Cat
SINBAD!!!!
Lady Luck – As an actual person
Prince of Persia – It is a Disney movie now, and I would LOVE for the show to use the sands of time.
Rupunzel – Tangled was such an awesome movie
A Valkyrie from the land of Valhalla
I’d love to see some creepy, obscure stuff on the show too, like a kushtaka. Remember the weird, Chinese, fire animal thing that turned into Philip? More stuff like that. Japanese culture has tons of occult stuff they could play around with. We need some ghosts on this show, like that wraith thing they had
I also want to see some fun references on the show, like references to works of Neil Gaiman or Princess Bride
