Doctor Caliostro
Doctor Caliostro is a minor antagonist in the Kingdom Hearts Unlimited Saga, only appearing briefly in "An Empire of Dreams" for the events of the second Pride Lands campaign.
A deranged humanoid scientist from Halloween Town, Dr. Caliostro was once part of the heart research internship program conducted by Count Curunir Dooku the Wise in the Radiant Garden Castle Dungeons. However, Calisotro's weak, lovesick heart proved inefficient for him to continue working on the project with the other apprentices safely, and Dooku was forced to let him go back to his homeworld. For years afterward, Caliostro worked in his underground laboratory in obscurity, using whatever spare notes that fellow scientist Dr. Finklestein lent him in addition to the heart research notes kept over from his previous assignment to begin construction on a device that could possibly strengthen the heart of select individuals against corruption and mutate them into the perfect beings in both appearance and might. It was Oogie Boogie who would hear word of Caliostro's experiments and approached him with an offer to join the Hellfire Organization as a possible intern scientist to help out with a little project that Lord Scar of the Pride Lands had developed long beforehand, and now his devoted queen Zira wants him to finish the job to help her seek her revenge against Simba...
