Alphonso Mackenzie is a S.H.I.E.L.D. mechanic. It is likely that he was previously a technician for S.H.I.E.L.D. and that Coulson discovered he was still loyal to S.H.I.E.L.D., subsequently offering him a place in his revamped organization.

Biography Edit

Early History Edit

Mack has a brother named Ruben who thinks Mack works for an insurance company.

The Day S.H.I.E.L.D. Fell Edit

During the events of Captain America: The Winter Soldier, Hydra sent an encrypted message out across all S.H.I.E.L.D. communication channels activating all Hydra sleeper agents within S.H.I.E.L.D. Hydra was determined to kill every S.H.I.E.L.D. agent and take control of every S.H.I.E.L.D. facility.

Mack was working on a S.H.I.E.L.D. ship, The Iliad, as its chief engineer when Hydra attacked. Mack was taken prisoner, but Bobbi and Izzy saved him.

Bobbi informed Mack of her mission to rescue Gonzales and Mack decides to help her. They found Gonzales in the ship's conference room with a broken leg. It was then Bobbi revealed Fury had given her a second mission to insert a disc into the ship's server core which would simultaneously detonate every weapon aboard the ship thereby sinking it. The Monolith was in the ship's cargo hold and Fury rather it be destroyed than let Hydra have it.

Mack and Gonzales agreed to help Bobbi with her mission, but when they reached the ship's server core Mack convinced Bobbi to change her mind as they were still S.H.I.E.L.D. agents aboard the ship fighting Hydra and if they sank the ship they'd kill them too.

It was then Bobbi, Izzy, Gonzales, and Mack decided to go against Fury's orders and retake the ship and, against all odds they succeeded.

Gonzales and the others decided to build a new S.H.I.E.L.D., one based around transparency and leaders being accountable for their actions.

When the "real" S.H.I.E.L.D. learned Fury had appointed Coulson to be the new director and Coulson was creating his own version of S.H.I.E.L.D., Gonzales didn't believe Coulson could be trusted thus he sent Bobbi and Mack undercover to infiltrate Coulson's organization and learn what secrets Coulson was keeping.

Season 2 Edit

During "Heavy is the Head", he and Fitz worked together on a way to neutralize Carl Creel. After Fitz told him that he, "did not fix it today," and Mack realized that Fitz meant that he had come up with the solution before, they went through Fitz's old designs and finally found a way to neutralize Carl Creel by upgrading the Overkill Device. After this, they seem to have become pretty close colleagues, if not friends. Mack also reverse engineered the cloaking system of the Quinjet the team stole during "Shadows" together with Antoine Triplett and installed it on the Bus. Mack questioned Fitz directly about how he was coping with the absence/loss of Simmons, although the younger man was looking at his own 'version' of her when he claimed to be okay.

By "Making Friends and Influencing People", Mack is working as a de facto interpreter, filling in the blanks for Fitz in the latter's vocabulary as Fitz attempts to brief the group.

In "Ye Who Enter Here," at the beginning of the episode, Mack gives Coulson a toy remote-controlled version of Lola as a present. However, it's later revealed that the toy actually has a scanner built into it meant to find where Coulson hid Fury's Toolbox.

Later, Coulson informs Mack and the others that they've located the alien city Hydra has been looking for. The City is underground, underneath San Juan, Puerto Rico, specifically under the Fort of San Cristobal. Fitz, Simmons, and Mack use the Mouse Hole to drill a hole into a shaft leading from the fort down into the City, but when they lose contact with the D.W.A.R.F.s they sent down the shaft they use a winch to lower Mack down into the City.

When Mack reaches the bottom, he notices symbols that match the symbols on the Diviner are carved into the floor. The symbols then begin glowing, the symbols then appear on Mack's hand, and Mack begins screaming. Coulson and the others pull Mack up, but as soon as he's out of the shaft his eyes turn red and he attacks them. Also, it appears Mack has peak-human strength now.

Mack tries to kill Bobbi and Fitz shoots him with an ICER, but it appear to have no effect. Mack then turns on Fitz, but Bobbi knocks him unconscious by electrocuting him with her batons. Mack then falls down the shaft into the City.

In "What They Become," Raina encounters Mack while she's in the City, he's still possessed by the alien energy and leads Raina to the temple. After the temple door seal shut, Mack returns to normal.

Mack's experience in the alien city left him with a permanent distrust of anything alien.

In "Aftershocks," Mack gets a copy of the base's blueprints from Coulson, saying he wants to inspect the base's ventilation system. However, the truth is Mack was getting the blueprints for Gonzales in order to help plan their attack on the base.

In "Who You Really Are," Coulson tells Mack he wants to make him a field agent, but Mack hesitates to accept Coulson's offer as he doesn't like violence.

Later, Hunter confronts Mack about the secret Bobbi and he have been keeping and, worried Hunter might tell Coulson, knocks Hunter unconscious and abducts him. When Hunter wakes up, he finds Mack has taken him aboard The Iliad.

In "One Door Closes," Coulson discovers Mack's deception when he finds the scanner inside the toy version of Lola Mack gave him. However, while Coulson is questioning Mack, Gonzales and his agents release a dendrotoxin gas into the base's air vents which knock everyone inside the base unconscious. Gonzles then frees Mack and the "real" S.H.I.E.L.D. captures the base. Coulson, however, escapes.

After Coulson opens the Toolbox for Gonzales and "theta protocol" is revealed, Gonzales feels Coulson can be trusted again thus the two organizations come together as one S.H.I.E.L.D. with Coulson reinstated as director.

In "Scars," Mack tells Coulson he's quitting S.H.I.E.L.D. because he still doesn't trust Coulson and refuses to be an agent as long as Coulsons director.

In "S.O.S. Part One," Mack changes his mind and remains at S.H.I.E.L.D. after he hears Gonzales is dead.

In "S.O.S. Part Two," Mack is forced to cut off Coulson's hand when he touches a terrigen crystal in order to save his life.

After the war with the inhumans was over, Coulson put Mack in charge of all of S.H.I.E.L.D.'s alien artifacts including The Monolith.

Season 3 Edit

In "Closure," Coulson leaves to go on a mission to kill Ward and while he's gone he makes Mack acting director as May is too shaken over what's happened to Andrew to be in charge and Mack is the only person who doesn't have a personal vendetta against Ward.

Later, Mack leads a mission to rescue Fitz and Simmons from a Hydra castle and to stop Hydra from bringing Hive back from Maveth through the Monolith portal.

In "Watchdogs," Mack goes home to visit his brother Ruben, but is called away by Coulson when a terrorist group called the Watchdogs destroys an A.T.C.U. facility.

Later, Daisy calls Mack to tell her they've found where the Watchdogs are going to be meeting to plan their next attack and Mack leaves to join her on the mission. However, while outside the Watchdog's base, Ruben arrives and the sound of his motorcycle alerts the Watchdogs. Ruben sees Mack shoot three Watchdog soldiers with an ICER, drives off, and Mack goes after him.

Back at the house, Ruben is furious about Mack keeping secrets from him, but they both get distracted when they hear a team of Watchdogs breaking into the house. The Watchdogs think Mack is an inhuman and have come to kill him. Mack and Ruben successfully fight off the Watchdogs, but Mack gets shot in the arm.

Daisy assures Ruben Mack and will be fine and Ruben has a newfound respect for his brother.
