Although the Marvel Comics character Domino has made a few appearances on various animated series over the years, Zazie Beetz’s upcoming performance in The Untitled Deadpool Sequel marks the first time Domino has been realized in live action.

Following our in-depth look at the complicated history of Josh Brolin’s Cable, we’re examining the history of everyone’s favorite luck-altering mutant, the mercenary known as Domino.

Domino is joining the cast of the untitled Deadpool sequel, played by Zazie Beetz.

Hard luck: Neena didn’t exactly have a normal childhood. She was created in a lab as part of a top-secret government program called Project Armageddon. The goal was to manipulate mutant genetics in the hope of creating an ultimate weapon. Although Project Armageddon was deemed a failure, Neena managed to not only survive but emerge with the ability to subconsciously manipulate probability itself, effectively boosting her own good luck and causing misfortune to anyone who might wish her harm.

With the help of her biological mother, Neena escaped the facility that made her, but her subsequent path was not without hardship. Using her powers to work as a top-level mercenary, Neena grew up with little knowledge of her true origins.

It was while working with the NSA that Neena was assigned to serve as a bodyguard for Dr. Milo Thurman, a scientist so intelligent he could accurately predict the future. It was Thurman who first gave Domino her nickname and who later gave her his own name — the pair was married, but their nuptials were short lived. The doctor’s life was seemingly claimed in a terrorist altercation.

Team player: Although details of their first encounter have never been revealed, Domino at some point became Cable’s trusted ally. She served with him on a mercenary team first known as the Wild Pack, then the Six Pack and finally as X-Force. The pair has even been romantically linked, but their dedication to the job always takes priority.

The Copycat conundrum: Domino was created by the same minds behind Deadpool, Fabian Nicieza and Rob Liefeld. She even made her first appearance in the same 1991 issue of “New Mutants” that launched the Merc with a Mouth… sort of. Even though Domino makes the cover, the woman inside the issue is actually the shapeshifting mutant Copycat. Copycat infiltrated the X-Force team at its inception, and it wasn’t until a year later that the real Domino finally arrived.

Copycat, by the way, is the comic book version of Vanessa Carlysle, played by Morena Baccarin on the big screen. Vanessa doesn’t seem to be a shapeshifting mutant in the first “Deadpool” movie, but who knows where the sequel might take the character.

Lazarus: Domino’s origins were initially explored in an eponymous 1997 comic book miniseries. In 2003, a second “Domino” miniseries took another look at Project Armageddon and revealed that Neena had a secret brother. Dubbed Lazarus, the child was kept in suspended animation for so long that, when an adult Domino found and rescued him, he was still biologically only five years old.

Alektorophobia: As tough as Domino is, she’s a bit of a chicken when it comes to, well, chickens. It was revealed in a 2010 issue of “Deadpool” that the luck-manipulating mutant detests farm fowl and counts the birds as her only true fear.
