4. Hodor
Who doesn't love Hodor? The gentle giant half-wit (played by Kristian Nairn) is the most innocent character on the entire show and he only says one word: Hodor. He literally responds to everything with "Hodor." And it's awesome. The best part about Hodor is that he's aware of all the terrible things that have happened so far and he would do anything to protect Bran and Rickon, the young fugitive members of the dispersed Stark family. He's extremely loyal and kind and he has to walk around all day with Bran on his back. Bran has strange dreams and complains a lot, so it must get a little annoying. A dream spin-off would involve Hodor somehow winning the Iron Throne and reigning until the end of his days. If anyone deserves the throne, it's this guy. Imagine Stannis Baratheon taking orders from Hodor? It would be magical.
