I have some character ideas (I apologize if this has already been implemented, but I doubt it since I've been playing for an hour straight).
1. Assassin: You have the choice of either giving them money(ex:300) or having them kill a good sum of your citizens(ex 30).
2. Mercenary: Can be hired to protect you from the Assassin for a sum of money(ex:150).
3. Royal Guard: Can be hired for free! Reduces the negative effects of other characters. (ex: if the eyeball comes in and the offer is a negative answer, the result wont be as bad, or if the Assassin wasn't given money, instead of losing 30 citizens, you would only lose 20)
4. Black Dog: Just barks, but it is unknowingly evil. If you give it food it will roam around the city dealing no harm to citizens, but if you refuse to feed it, everyday it will kill off 2 citizens, until it reappears again.
5. Live Stock Farmers: Farmers! Brings in money, produces live stock for citizens.
6. Cyclops: Can be killed just like the dragon. You are given the choice to give it 400 gold or it will take the lives of people and live stock everyday until you meet it again.
7. Elf: Specializes in only good magical spells for free.
8. Grim Reaper: For a sum of 1500 it will leave you alone for the rest of the game, else it will kill off citizens at an alarming rate. The only way to stop it if you do not pay up is by having the witch reappear and have her say she will kill the grim reaper for 1000 gold instead of the 1500 (which must happen quite sometime after the grim reaper if you refuse to give up the gold... Its a punishment).
9. Imp: Harmless in nature, likes to play pranks on people. Some people may find it disturbing or annoying to keep around.
10. Shapeshifter: Can imitate any character in the game. The only way to find out if the character is real or not is by noticing the bad grammar.(you will ALWAYS want to say No to this character as it will take twice as much money as the original offer, without telling you that. EX: (the joker needs 200 to upgrade the juggling balls, it will show it needs 200, but in-turn it will take 400 instead, with the reply "FOOL, YOU UNDERSTAND NOTHING"(totally not from soul eater - *sarcasm*).
11. Werewolf: Only appears in the afternoon, Considered a threat to citizens and must be captured. When/if captured you are given the chance to give him to the scientists to cure him or throw him in the cell'er.
12. Leprechauns: If you let them sell their new cereal brand, you get free gold at the end of each day! ;)
13. No more ideas. D:
