Others have used the name Dr X. See Dr. X.
Dr. X was a midcard rudo for CMLL. He's was distinguishable by the big X across all of his masks. He's was member of Pandilla Guerrera, and had notable feuds with Tigre Blanco and La Mascara to start and end his National Welterweight Title reign, though the middle wasn't much to write about (one known defense over 2 years.) His National Trios Title reign with Nitro and Sangre Azteca was more active, establishing them as a strong trio.
Like most of his group mates, Dr. X was a solid midcarder who been in that role for quite some time and appeared as if he'd be there for quite some time longer. Previous to his Pandilla membership, there were hints of a team up or a feud with fellow doctor Dr. Wagner Jr., but nothing ever came of it.
Dr. X was previously known as Dr. O'Borman Jr.. He rented the name from the original Dr. O'Borman and was a member of La Nueva Ola Blanca. He changed the name late in 2000. It was explained at the time that Dr. O'Borman wanted to allow his own son to use his name, and that Dr. X didn't want to pay the fee to use the name anyway. The replacement Dr. O'Borman Jr. didn't last long and was believed to not actually be the original's son. Dr. X would much later leave CMLL and change his name at that time, so it's likely it was CMLL itself who either no longer wanted to pay the fee or decided they rather own the name themslves.
In 2011, Dr. X began a feud with Fuego, which seemed to be heading to a mask match. Dr. X later told the media that he was offered the mask match, but no assurance from CMLL that he'd be kept around if he lost the mask match. Dr. X decided to instead leave CMLL without doing the match, and changed his name to Dr. X-Treme. Dr. X-Treme appeared in the Perros del Mal (promotion) among other indies, but his indie run lasted only couple months.
Dr. X was shot and killed at a neighborhood party on October 11th. The report of his death was Dr. X was not the target of the violence. He'd simply been trying to break up a fight at the party and died when a gun went off in the scuffle.
