Origin

Chavez was created by Joe Casey and Nick Dragotta for Vengeance #1 in 2011 but her backstory and abilities were only explored in 2013 in Kieron Gillen and Jamie McKelvie's Young Avengers.

MCU entry

Chavez's first MCU appearance was alongside Benedict Cumberbatch's Stephen Strange inĀ  Doctor Strange in the Multiverse of Madness who put everything at stake
to help her.

Backstory

Chavez is from Utopian Parallel where she was raised by mothers who were co-rulers
of this dimension. When mysterious forces attacked their universe, Chavez's mothers sacrificed themselves.

Development

After the death of her mothers, Chavez fled from her home. In Doctor Strange 2, Xochitl Gomez essayed the role of Chavez who traveled across universes by conjuring
star-shaped portals.

Powers

Contrary to the film, Chavez can control
her powers quite well. She has superhuman strength, durability, speed, and the ability to fly. Her star-shaped portals break barriers between dimensions.
