NPCs from Popular Media
Ever wanted your favorite character from video games, anime, or movies in your game? They just might be available for download!
Note: This is not an exhaustive list, but I have not included vanilla NPC replacers (there are far too many to list!), NPCs with next to no content, NPCs broken in 1.6, NPCs with no EN translation, or NPCs that violate Nexus TOS. If I'm missing something that isn't one of the above, let me know!
