Okay, my apologies for the double-post, but I have spent some time looking through every protagonist and antagonist in Disney and have the following concepts:
WALL-E (WALL-E): Meet Wally, the owner of the town's scrapyard, he is almost always smeared with oil and grease while he works on his projects (sculptures made of junk) and selling them off. If anyone needs to find junk that could be treasure, he's your guy. Has a dream of building a ship and going into space.
Basil of Baker Street (Great Mouse Detective): Meet Basil, the town's private eye/detective. Obsessed with Sherlock Holmes, his office is full of boxed that have well-read detective stories stacked high. He also keeps two trained mice that he's named Holmes and Watson. He's the man to go to when something needs finding.
Dr. Facilier (Princess and the Frog): Meet Dr. Hannibal Facilier, who runs the occult shop in town. The man is greedy, but his smooth-talking, charming personality charms customers into spending more than they wanted to. In truth, he is cruel, remorseless and sadistic with absolutely no morals, willing to step on anyone to get his way. He is known to be the resident Voodoo expert and uses Tarots to read people's destiny, thus providing other reasons for customers to be drawn into his shop.
I can't quite decide between the three though. Is there a specific role that the town needs? I know that antagonists seem to be somewhat higher than protagonists, so I can easily go with Basil and WALL-E. I just love the character ideas so much, I don't know who to choose! >_<
