Tamagotchi Monster
Released September 1998
Debirutchi no Tamagotchi, more commonly referred to as Devilgotchi, was released as the antithesis to Tamagotchi Angel. In this release, you raised a devil, one which would repeatedly attempt to play pranks on you. This Tamagotchi was never released outside of Japan in physical form, however it was released as a Java-based mobile game in Europe known as Tamagotchi Monster, which confirmed the English name of the line.
