Mimi is a female Spix's Macaw and supporting character in Rio 2. She is voiced by Rita Moreno. Mimi is Eduardo's older sister, Jewel's aunt, Blu's aunt-in-law, and Bia, Carla, and Tiago's great-aunt. She is the self-appointed adviser of the Spix's Macaw clan.
Mimi is described as being funny, brassy, and not afraid to speak her mind against Eduardo, and she welcomes Blu and Jewel into the tribe with open wings.
While the Macaw tribe members respect and fear Eduardo and obey his every rule, Mimi is the only one brassy enough to challenge him and give him a piece of her mind. Mimi lovingly welcomes both Jewel and Blu with open wings and tries to smooth over the conflict between Blu and Eduardo. She reminds her headstrong brother that despite what he may think of his new son-in-law, he must accept the fact that Jewel is all grown up and has another man in her life.
Mimi is sassy, kind and very cheerful. She is accepting and welcoming, and smooths arguments and tension. She loves her family and friends, no matter what they may do wrong, and is friendly toward others.
