me personally I pronounce it MewZera
If you go back in time, there has always been a select few people that cement their name so prominently in history for their achievements that everyone after them tried to mimic them.
In Rome it was Caesar:
Not only were future emperors after Augustus named Caesar, but if you look at the title for "Emperor" in Germany and Russia, Kaiser and Czar, both are derived from "Caesar".
In CS:GO, long ago, there was once a legend that defined Brazil in tactical FPS, he was a terminator who could enter a flow state so powerful that he could create the most miraculous and awe-inspiring clutches; He was a CS God. His name was Coldzera.
Zera doesn't mean anything, but the impact Coldzera's left in CS, and subsequently valorant as a result of all the former CS pros in the scene, his name still lives on in the IGNs of those that looked up to him back in the day.
