Interesting observation from the link to the Overwatch site:

If “Tekhartha” really is Zenyatta’s given/first name, then he shares it with Mondatta:

…the monks, led by the enigmatic robot known as Tekhartha Mondatta, sought to heal the wounds caused by the Omnic Crisis a generation earlier and bring humans and robots back into societal harmony.

Has it ever been confirmed exactly where the Shambali originate from? In some Asian languages it’s customary for the family name to come before the given name, so perhaps Tekhartha is the family name that members the Shambali share either because they share an origin or because they chose a new one to represent their brotherhood. In this case, “Zenyatta” and “Mondatta” are their given names, and “Tekhartha” is rather their shared family name.

Or perhaps “Tekhartha” is also a title/honorific which is used as part of Zenyatta’s name now.

Or perhaps it’s just a really weird coincidence.

Interesting stuff regardless.
