Biography
Alexander Pierce is a HYDRA agent who infiltrated the World Security Council. During a hostage situation in Bogata, he met S.H.I.E.L.D. agent Nick Fury, who sucessfully saved the hostages, including Pierce's daughter. Pierce was surprised by Fury's performance and later made him the director of S.H.I.E.L.D.

Decades later, the influence of HYDRA over S.H.I.E.L.D. has grown stronger, and a set of three heavily armed Helicarriers are built under "Project Insight." The Helicarriers were allegedly supposed to form a security network to protect the Earth, but HYDRA actually desired to use them to target and kill approximately 20 million people selected by Arnim Zola's algorithm, any individual which would pose a thread for Hydra's new world order.

After discovering the hijacking of a S.H.I.E.L.D. boat by Georges Batroc was actually planned by Fury in order to recover confidential files related to the Project Insight, Pierce deploys the Winter Soldier to kill him. After being attacked by the Winter Soldier, a heavily damaged Fury contacts Captain America and tells the Captain not to trust anyone as S.H.I.E.L.D. had been compromised, before seemingly perishing.

Following Fury's apparent demise, Pierce talks with Captain America, and discovers that Rogers has hidden something from him. Pierce deploys other corrupt S.H.I.E.L.D. agents to capture Cap, who goes undercover along with Black Widow. A new assignment is given to the Winter Soldier by Alexander, to kill Rogers and Romanoff. After gaining information related to the true objective of Project Insight from the hand of Jasper Sitwell, Rogers, Romanoff and their ally Falcon are captured by S.H.I.E.L.D., but they soon escaped captivity.

Pierce proceeds to continue with his plan, but as S.H.I.E.L.D. is getting prepared to deploy the Helicarriers, Captain America infiltrates the Triskelion and reveals by loudspeaker the truth of HYDRA influencing S.H.I.E.L.D. and prompts every clean agent to stand up against HYDRA. While Captain America and Falcon infiltrated the Helicarriers to modify their programming to change the targets from the people selected by Zola's algorithm to the Helicarriers themselves, Black Widow rescues the rest of the members of the World Security Council, who have been taken hostage by Pierce, and forces him to help her and Nick Fury, who reveals his survival to Pierce, to unlock every single one of S.H.I.E.L.D./HYDRA's secrets and upload them to the Internet. However, Pierce attempts to use a remotely-controlled miniature explosive he had hidden in Black Widow's clothes to force Fury to let him go. Using a micro-EMP, Black Widow disables the bomb, and thus Fury has the liberty to shoot Pierce.

As he lies dying, witnessing his fleet and plans in destruction, Pierce utters "Hail Hydra..." and dies. His partners-in-crime would then later meet their fates at the hands of S.H.I.E.L.D in the battle. Except from Bucky, who is beginning to remember both his past and who he really is: Bucky.

In a battle on one of the helicarriers, the Winter Soldier shoots Rogers. However, it turned out that death is not taking him yet, as Rogers immediately replaces the final chip, allowing Hill to take control and destroy all three vessels. The Helicarrier carrying Rogers and the Winter Soldier crashes into the side of the Triskelion, killing Agent Rumlow, who had earlier tried to capture Rogers, while Wilson escapes.

The Helicarriers are destroyed in process, and HYDRA's secrets are released to the world. Rogers falls into the river, but is suddenly saved by the Winter Soldier, who then leaves. Alexander Pierce dies in vain, as he likely dies at hands of Bucky in retribution for what he did to him, with Project Insight dies with him.
