My question is simple. Have there ever been any characters, or actors of Indian descent in any of the Star Trek official canon, and if not is there some in universe explanation/theory as to why they are so vastly under represented?
The caveat here is that yes I am aware that Khan Noonien Singh has an Indian last name. I cannot recall though if in TOS or the original Wrath of Khan if they explicitly communicated if he is in fact of Indian descent. For that matter if he was of Indian descent, why in multiple appearances of this character did they not use the opportunity to cast an Indian actor to play Khan?
Are there any in universe or out of universe explanations for the lack of representation here? In a prior nuclear war did Pakistan and India blow each other off the map?
