Conceived as "more than just another fearsome alien", the "Deep Space Nine" makeup department searched for concepts depicting "toughness and resiliency" in the design of the Jem'Hadar. The final design was based on a rhinoceros, with some added ceratopian traits. Originally designed on the premise that they were all clones, the first Jem'Hadar seen onscreen were all made to look identical to one another, though as they became more deeply woven into the storylines, each Jem'Hadar was given a distinctive look.
