HistoryDecades ago, Acronix and his twin brother Krux would become known by Master Wu. They would have engaged in a fight with Wu and Garmadon at the Monastery, as depicted in a painting at the Museum. They would then somehow, suffer a fate that would leave them 'lost to time'.
Falling asleep at home following his battle with Clouse, Wu would be stricken by a horrible nightmare filled with several visions of the past, such as the return of Acronix and Krux.

- Acronix is named after Acronis, a digital file sharing software used for processing the show.
