The first Digimon anime introduced the Digimon life cycle: They age in a similar fashion to real organisms, but do not die under normal circumstances because they are made of reconfigurable data, which can be seen throughout the show. Any Digimon that receives a fatal wound will dissolve into infinitesimal bits of data. <answer>The data then recomposes itself as a Digi-Egg, which will hatch when rubbed gently</answer>, and the Digimon goes through its life cycle again.
