Tahir or Black Zero

Tahir is portrayed as perhaps the most important member of the secret service. He knows that Imran is X-2 and plays the role of X-2 in Imran's absence.

In Darindon Ki Basti Imran realizes that his coworkers, mainly Juliana Fitzwater, are beginning to suspect that he is X-2. To permanently remove their suspicions, he decides to induct another member, codenamed "Black Zero" into the Secret Service. However, the original Black Zero is killed. Imran therefore appoints Tahir to the job and assigns him the Black Zero codename. The members of the secret service know him only as Mr. Tahir, the caretaker of Rana Palace.

Black Zero is Imran's favorite subordinate, but none of the members of Secret Service know about his true identity. He can replicate X-2's deep, hoarse voice to give orders to Secret Service agents when Imran is not available.
