Zozi is Bartok's partner in Bartok the Magnificent. He is voiced by Kelsey Grammer.
Zozi is a bear who appears at the climax of Bartok's act playing a ravenous wild beast for Bartok to defeat. Although his act is mainly roaring, Zozi considers himself a great thespian and is prone to wandering off into lengthy quotations from Shakespeare or famous Greek tragedies before Bartok brings him back to the matter at hand, and is eager for any excuse to dress up as a new character. He has a wry sense of humor that allows him to see through the bat's sometimes dishonest nature, and his ego.
He is the one who often gives good advice to Bartok, and is a supportive partner to Bartok, although he did not like the fact that Bartok kept the ring that Prince Ivan gave him, he sees that a true hero doesn't take advantage of getting a reward, so tries to convince Bartok to give it back to Ivan.
When Bartok is sent to rescue Prince Ivan, Zozi at first pleads silently for Bartok to refuse, but when Bartok feels compelled to agree, Zozi insists he go through with the quest.
In the scenes of the Skull it shows he is quite experienced with riddles, especially the ones Bartok can't understand, allowing them to get through to Baba Yaga's house. He is forbidden by Baba Yaga from helping Bartok accomplish the tasks she sets him. However, when Bartok is about to give up in frustration during the third task, Zozi slyly suggests giving up the quest, and that Bartok will never be able to succeed. The subtle taunt convinces Bartok not to give up, and allows him to figure out how to complete the task.
Later on, although Bartok instructs Zozi to remain hidden, the bear follows Bartok into the palace, allowing him to rescue Bartok, as well as Prince Ivan and his guard Vol, when Ludmilla imprisons them in a chamber filling with water. After releasing Bartok, Zozi helps Vol and Ivan to safety, keeping them entertained reciting from Aeschylus' play Agamemnon. Vol and Ivan compliment Zozi on his delivery, which the bear is quite grateful for.
After Bartok defeats the dragon-Ludmilla, Zozi compliments Bartok on proving himself a true hero, and again encourages him to return Ivan's ring. After his heroic adventures, the bat feels much more ready to do the right thing.
