Zenny

Zenny (ゼニー), Ƶ, also known as Zeny and Zeni, is the currency from several Capcom games, including the Mega Man series, the Breath of Fire series, Forgotten Worlds and the Monster Hunter Series.

Its first appearance in a Mega Man game was in Wily and Right's RockBoard: That's Paradise, and also appeared in Rockman: Battle & Chase and Mega Man X: Command Mission. All of the games in the Mega Man Legends series, MegaMan Battle Network series and MegaMan Star Force Series also use Zennies as a currency. They probably parallel yens in a way as even cheap items tend to be in the 100's.

Trivia

 * Zenny is a common currency often used in other franchises, such as those of Dragon Ball and Ragnarök Online franchises.
