The Crimson-Masked Saiyan, or simply just Crimson, is an incarnation of Goku Black (ゴクウブラック Gokū Burakku) whose fate was changed by Fu’s intervention.

Crimson sought to fully master his body by killing numerous incarnations of Goku across every timeline, while also planned to complete Project Zero Mortals by wiping out mortals across every reality. His method was to populate the Pseudo Universe with mortals and then wiping them out, which in turn would kill all of the mortals in Universe 7.

Crimson serves as primarily a major antagonist for most of the New Space-Time War Saga.

Crimson’s appearance has the same general look as Goku Black, having Goku’s body while with a slightly darker skin tone and more defined and sterner eyes, along with a somewhat skinnier physique. His hair is also a noticeably darker shade of black with only four front spikes and three back ones.
