Majid Sadiq is the leader of The Engineers and the main antagonist of Tom Clancy's Splinter Cell: Blacklist. He is voiced by actor Carlo Rota.
Sadiq was born in London, England, into the third generation of a family of Pakistani decent, and was recruited into MI6 right out of university. The United Kingdom had deemed Sadiq a perfect agent, as he was middle eastern but not very political or religious. However, on an undercover mission in Iraq, he was flipped when a U.S. drone strike bombed an insurgent training camp near the Persian border and the village he was stationed at was nearly destroyed. Sadiq was then burnt by MI6 and they attempted to capture him, but he evaded the British agency. They listed him as K.I.A, but is secretly the 5th most wanted individual in the United Kingdom.
Ever since, Sadiq had become the leader of The Engineers, an anti-western terrorist group aiming to remove American influence in other countries in the world.
Fourth Echelon first identifies Sadiq at compound in Mirawa, Iraq on a video of him executing a U.S. soldier by slitting his throat before threatening the viewer. Later, after Sam Fisher was critically injured by nerve gases, he was brought to Sadiq for interrogation (and possibly execution). However, before Sadiq can go any further, he was interrupted by Isaac Briggs, who engaged in a firefight with the former. Once he ran out of rounds in his Makarov PM-B, Sadiq made a run for it after Briggs went against orders from Sam to take a final shot. Upon finding out about the failure of American Consumption and American Freedom, he and The Engineers sped up the Blacklist, going two days until an attack instead of seven, and remotely sabotages the C-157 Paladin (but Fourth Echelon managed to restart with the help of Andriy Kobin). But with the amount of time that 4E was distracted, Sadiq was able to successfully carry out American Fuel and push the U.S. Government to "Continuity of Government".
After retaking the LNG Terminal in Sabine Pass, Louisiana, Fourth Echelon went to stop Sadiq against President Caldwell's orders. Sadiq manage to capture the Secretary of Defense and had him slightly tortured in order to transfer data files to whoever is backing the Engineers (which was The Engineer's actual plan the whole time, because he knew the United States would never agree with their demands). While one of his men were lopping off the SECDEF's left ring finger, Sadiq captures Briggs and cuts out his sub-dermal radio with his karambit and crushes it, but not before warning Fisher to stay away if Briggs knows what's good for him. After bringing Briggs to the war room, he's threatens the SECDEF enough to start the file transfer. However, before going any further, Briggs grabs the SECDEF and employs the Fifth Freedom by breaking his neck, thus killing him and preventing Sadiq from getting what he wants.
After beating up Briggs, Sadiq gathers the hostages (with Fisher acting among the hostages) and proceeds with boarding and hijacking the Paladin. Unfortunately for Sadiq, all of his men were killed by 4E snipers, but he then wounds Briggs in the left arm and runs for the Paladin. He was then stopped by Fisher when the latter shoots him in the left shoulder and slits his knee in two places. Sadiq then reveals to Fisher that he and The Engineers work for twelve rogue nations and that if Fisher kills him right then and there, those nations will rise up, and if he were to be put on a war crimes tribunal then Sadiq will "spill every secret he knows", possibly giving the twelve nations the correct means to attack, meaning that either way, it would lead to a negative mass event. Having no other option, Fisher employs the Fifth Freedom and unofficially imprisons Sadiq.
After the failure of the Blacklist, Sadiq was last seen in an interrogation room (possibly Guantanamo Bay in Cuba), being approached by a fully recovered Victor Coste, although, to ensure the greater good of the public, Sadiq was announced dead by Caldwell.
