|Full Name:||Alexander Marcus|
|Previous Assignment:||XO, CO, USS Enterprise|
|Assignment:||CO, Starfleet Command|
|Final Assignment:||CO, USS Vengeance|
Alexander Marcus was a Human male who was the first officer of an earlier USS Enterprise (which existed subsequent to the NX-01 Enterprise, but prior to the USS Enterprise). He served under the command of and befriended Robert April. He is the father of Carol Marcus. (TOS comics: "Countdown to Darkness, Number One", "Countdown to Darkness, Number Two"; TOS movie: Star Trek Into Darkness)
- IDW Star Trek, Issue 19 includes a character who looks similar to Peter Weller, the actor who plays Marcus - the character's name is not mentioned, so it is unclear if this is supposed to be Marcus. The issue later mentions a Starfleet admissions board member named Commander Marcus. Again, it is unclear if this is supposed to be Alex Marcus.
In 2239, Marcus helped Robert April fake his death and start smuggling Federation-Starfleet weapons to the non-Shadow Phaedans. According to April, he and Marcus maintained contact throughout the years. According to Robert April in 2260, Marcus was likely responsible for making sure that a Section 31 computer program was built into the USS Enterprise, allowing for control of the ship to be taken away from its crew. (TOS comics: "Countdown to Darkness, Issue 3", "After Darkness, Part 1")
Later, Marcus would rise through the ranks of Starfleet and become the organization's commanding officer. During his rise, he convinced Christopher Pike to join Starfleet. As commander of the organization, Marcus initiated a plan following Nero's incursion that led to Section 31 doing intensive weapons research and deep survey missions, using the knowledge of Khan Noonien Singh, under the alias "John Harrison", to create these weapons. He also recruited Lieutenant Yuki Sulu to help keep a eye on Khan following Khan's surgical alteration and brainwshing .
Marcus at first had Khan believe that he was suffering from amnesia from a mission to Qo'noS. He also approved of his plan to destroy Praxis. Marcus then allowed Khan to complete the modifications on his torpedoes personally in London. After Khan had his crew place inside the torpedoes, Marcus was confronted by Khan at his home in San Francisco. Marcus at first thought Khan was going to kill, but Khan demanded that he be told the truth about how he was found. After Marcus told him the truth, Marcus was then strangled by Khan. However, Marcus was able to call up two Jumpships. He then told Khan that he knew that his people were inside the torpedoes and that they would be destroyed. (TOS - Khan comics: "Issue 4", "Issue 5")
He then forced Khan to work by threatening the lives of Khan's crew, leading Khan to put his comrades in experimental photon torpedoes he created for Section 31 as a means of saving them. Eventually, Khan came to believe Marcus killed the other Augments so he went rogue and launched terrorist attacks on the Kelvin Memorial Archive and Starfleet Headquarters. This attack left Christopher Pike dead and Marcus shaken from the attack. Marcus then dispatched Captain James Kirk to hunt down and kill Khan with the torpedoes that Khan had hidden the other Augments in. This caused Khan to surrender to Kirk, an action that enraged Marcus and caused him to pursue the Enterprise in the USS Vengeance. The Vengeance and Enterprise engaged in battle and Kirk ended up allying with Khan and boarding the warship. while aboard the ship, Khan ended up killing Marcus by crushing his skull.
