“Meu tío iauaretê” relates a story about a human which turns into an animal. This transformation shows an identity crossover between Nature, Culture, Language and Politics. Based on this, we propose a reading which consists in deconstruct the human state in front of the animal. The consequences of this transformation changes language, politics and make a new sense of community. Becoming animal in this reading defies the Biopolitics as the set of rules over life. As results of this challenge this situation proposes a Cosmopolitical relationship (Viveiros de Castro, Metafísicas caníbales) between different living beings through the alliance, which resists the anthropogenic machine.
