Domino, also known as dominoes or domino blocks, is a type of gaming piece with a rectangular base and a line in the middle that visually separates it into two square ends, called pips. Dominoes are traditionally made from bone, silver lip oyster shell (mother of pearl), ivory, or a dark hardwood such as ebony and feature contrasting black or white pips on one side. Some sets also have a combination of these materials, with the top half of the domino being thicker in mother of pearl or ivory and the bottom being thin and ebony.

A psionically augmented mutant with the ability to subliminally and telekinetically affect probability in her favor, Domino is often described as having “good luck”. This ability is unconsciously controlled, though she has shown the ability to consciously trigger it if she puts herself in danger, such as when she caused lightning to strike two Sentinels during Civil War: X-Men #1.

She was recruited by Wolverine and the new black ops team, X-Force, to help capture Vanisher. After that she fought against Donald Pierce and Lady Deathstrike, helping to free Milo Thurman from their control. She later fought the Hecatomb and was sent to Rumekistan to aid Cable, where she helped to defeat Flagsmasher. During the ensuing battle, she was wounded and lost her powers. She was then attacked by a time-traveling Halloween Jack who snatched her out of the timeline, but Dom’s psionic abilities enabled her to return to the present.

Despite being a powerful and well-trained assassin, Domino is often seen to have poor reflexes and can be taken down by even the smallest nudge. This is due to her inability to process impulses quickly, which hampers her reaction time and coordination. She is also unable to make decisions quickly, which can lead to her being taken advantage of by more skilled foes.

While dominoes are primarily used for blocking and scoring games, they can also be used in non-blocking or trick-taking games. Many of these games use multiple sets of dominoes to create a larger game board, and they may be played with one player or multiple players.

Domino has the ability to set off a chain reaction by pushing on the first domino, which then pushes on all of its neighbors until they fall over as well. This can be a powerful tool for creating tension and excitement in a story, as each of these scene dominoes can then have its own consequences. Whether you compose your novel off the cuff or spend months outlining every detail, thinking about how to incorporate dominoes into your story can be an effective way to build your plot.
