Locke & Key artist and co-creator Gabriel Rodriguez, colorist Jay Fotos, and writer Chris Ryall bring readers the complete, extra-length tale of a cyborg warrior who calls herself Onyx. The exciting Onyx one-shot story will land on shelves this September and be published by Image Comics and Syzygy.

Onyx arrives in a near-future Nigeria beset by overpopulation and food shortages alongside another alien entity that corrupts all lifeforms in its presence. Is Onyx here to save the planet or, in its final throes, will she help hasten its destruction?

Onyx one-shot (Diamond Code JUL220072) will be available at comic book shops on Wednesday, September 28.
