Abstract
In Kafka's work there are many examples of metamorphic instances. Die Verwandlung is obviously the first case that we are used to know as a real metamorphic example. However, it is not the only one, for examples Odradek, but also the way Kafka describes the encounter between characters or the characteristics of some of them (Das Schloss). The paper tries to conceptualize the metamorphosis through a distinction between two forms: (1) metamorphosis or transformation that allows us to know from where what is transformed comes (start) and where it arrives (arrival); (2) becoming that shows a tension between two different conditions or that not allows us to grasp something because of his intangibility. All this will be examined using the monumental work of Deleuze and Guattari and a phenomenology of metamorphosis developed by Conci.
