Marvel & DC Omnibus

X-23 is the most fully realized Wolverine spin-off character ever created — Craig Kyle and Christopher Yost conceived her as a female clone of Wolverine weaponized from birth, used as an assassin by the Weapon X program offshoot known as the Facility, and their work establishing her origin in the animated series was adapted into the comics in one of the medium's most harrowing backstory sequences. The first omnibus covers her origin and early missions, establishing the psychological damage that Tom Taylor would later translate into Marvel's best all-ages superhero series.
