Ivan is the circus' magician. Prior to the circus being re-established, his magic acts consisted of doves until a new policy about animals was established, causing Ivan and his wife to release their doves back into the wild.
Ivan and his wife Catherine witness Joe and Milly running past them, telling them that he and Catherine will be coming to the train station. Ivan and his wife later stand next to each other near Holt just as he introduces the couple by name. After a reminder from Max Medici, Ivan and the other workers return to work to continue building the tent. The next day, Ivan and the other performers gaze upon Baby Jumbo, recently born to Mrs. Jumbo in awe. Later when Max tells Holt to make Baby Jumbo's ear smaller before the deadline he is given, Ivan then shrugs, telling Holt not to blame him for the trouble. He and his wife Catherine later entertain guests at nighttime in front of some guests in the freak show section.
The next day, Ivan and the other performers sadly gaze upon Mrs. Jumbo being taken away just as Dumbo is sent to perform in the clown act, no longer including him in the elephant act. Later during Dumbo's next act, Ivan and his wife watch Dumbo in the role of a firefighter clown and as the platform begins to collapse due to one of the clowns' clumsiness, Catherine and her husband become fearful about this; thanks to Milly's help, Dumbo manages to fly around the circus.
Furthermore, Ivan and the other performers travel to Arkansas in the Dreamland attraction as Dumbo's act was a success. After it is found out that Vandevere Enterprises has fried all the circus performers, Holt, his children Joe and Milly, and the circus performers plan to rescue Dumbo by releasing back into the wild him alongside his mother. Ivan plays an important role in arriving at Nightmare Island by where he and the other performers barge into the attraction as he and Catherine work together to put in the fog effects to distract the dangerous animals and to turn of the lights to confuse the guards just as the performers take the transport vehicle with Mrs. Jumbo in it just before the park owner V.A. Vandevere and his guards try to stop the circus troupe. Later, Ivan, Holt's family, and the rest of the circus performers spend their last moments with Dumbo and his mother before they get released into the jungle.
At the end of the film, Ivan and his wife Catherine are seen releasing a dove as part of a new policy of not including animals in the circus.
