Why Klingons Look Different From Discovery To Strange New Worlds

CBR

Strange New Worlds revisits Starfleet's aversion to genetic modification, but the Klingons in the series may be a product of that outlawed science.

The appearance of Klingons in Star Trek has evolved over time, with the original series using minimal makeup due to their tight budget.
Later series introduced cranial ridges, and Discovery created a more alien look for the Klingons.
Genetic modification is explored as a possible explanation for the appearance differences, with Enterprise featuring a storyline involving a virus that caused Klingons to lose their distinctive features. Strange New Worlds may continue this storyline.
