This bird's low IQ made him the perfect puppet to put into power by the Dark Alchemist. The Dark Alchemist is able to run his evil operation within the protected gates of Cloud Kingdom in secret, while using King Dodo as a front. The last of his kind, King Dodo intends to live in luxury and style. He doesn't mind being a puppet if he can wear a crown and chain.
Each mastery level adds another card to the cardpool for defeating King Dodo. Each of the bronze, silver, and gold mastery levels unlocks a new card, while it takes all three diamond and onyx levels to unlock a single card.
