Metamorphosis Intro

In The Metamorphosis, Franz Kafka introduces the existential character, Gregor Samsa, who turns into a gigantic bug.  Eventually this causes another metamorhophosis to occur to his younger sister Grete.  While Gregor undergoes a physical change, Grete transforms from child to adult.  Gregor and Grete's metamorphoses contribute to Kafka's overall meaning, which is:  in the end everyone is alone and will die that way.
