Thadeo Kayunimura is the protagonist of Evolver. Having been born to two of the most powerful reactors of the Last Great War, Thadeo has no unique Soul Data of his own and is, as such, an Evolver. While Thadeo spends the beginning of his adult years laying low as a mercenary for his surrogate mother Maudeline Popperidge, his desire to live quietly is ultimately snuffed out by destiny pushing him toward the fate that awaits him.
