The diminutive alien species of Keenser, Montgomery Scott's taciturn assistant in the three Kelvin-timeline films, with rough greenish skin, dark eyes and a name supplied by tie-in material.
The Roylans are represented on screen by a single individual, Keenser, played by Deep Roy. He is about half the height of a human, with a hard, pitted hide and large black eyes, and says very little.
Keenser first appears in Star Trek (2009) as Scott's only companion at the remote Starfleet outpost on Delta Vega. He follows Scott to the Enterprise and serves in engineering in Star Trek Into Darkness, where he resigns alongside his friend, and in Star Trek Beyond, where he is suffering from a cold that makes him sneeze a corrosive green fluid.
The films never name his people. The word Roylan, a nod to the actor, comes from licensed tie-in material connected with the films and has been widely adopted by fans and reference works. Nothing about the species' homeworld or culture has been shown.
