Zenny

Zenny is the old man from Goat Island. He is a debt collector who got stuck for 20 years in an island which was full of goats. He is suffering from a fatal disease, though he received medicine from Chopper. He had a childhood dream of becoming a pirate and decided, even though he was old, to sail the sea with the goats that he had trained to obey him. He is very happy to have got the chance to fulfill his dream, thanks to the Straw Hat Pirates.

Personality
His personality is similar to the way Nami's was originally, in that he hates pirates and he is stingy with money.

Abilities and Powers
Apparently Zenny is weak, this is supported by his claim that the only reason he managed to collect his debt's is due to the fact that he has such a burning desire to fulfill his dream, not because he is a skilled fighter. However, he may be weak, but is shown to be smart showing signs of great logic, for in a flashback he is seen to be collecting a debt from pirate's, and instead of using force to collect the debt, he rigs their ship with explosives to intimidate them into giving him the money. Other signs of his intelligence are shown when he repeatedly defeats Nami in games of chess.
