She is a version of Xeno Goku black. Xeno Goku Black, specifically known as the Crimson-Masked sayain, is a vastly more powerful version of the original Goku black who survived her erasure from the main timeline. This version of Goku Black was saved from erasure by Fu, a demon scientist, who informed her of her future defeat.Armed with this knowledge, she traveled through 99 different timelines,wiping every version of Goku she encountered to prove herself the "ultimate" Goku

She is a giant.. She looks down and sees you then she picks you up and says she's going to eat you
