Shotgun-Axe

"Well, I'd like to be in a fight. Built this damn thing for a reason."

- Alphonso Mackenzie

The Shotgun-Axe is a weapon crafted by Alphonso Mackenzie to be used as both a firearm and a melee weapon. He completed it in time to fight Hive's Primitives on the Zephyr One, which is capable of firing normal and I.C.E.R. shells.

First Ideas
"I need a bigger gun, I guess. Or my axe. Or maybe a shotgun-axe combination of some sort."

- Alphonso Mackenzie

Following the fall of Afterlife and the release of the Terrigen, S.H.I.E.L.D. tried to recruit Lincoln Campbell to assist them in their efforts to help new Inhumans come to terms with their new powers. This became especially important after S.H.I.E.L.D. managed to rescue Joey Gutierrez from the Advanced Threat Containment Unit. Daisy Johnson and Alphonso Mackenzie paid Campbell a visit at the hospital where he had worked since the fall of Afterlife. However as they tried to convince him to come to S.H.I.E.L.D., a new Inhuman, which S.H.I.E.L.D. would later name Lash, stormed into the hospital demanding that a baffled security officer tell him where "the Inhuman" was. Lash quickly found Campbell on his own, sparking a skirmish in the hospital. After using significant resources on Lash, the monstrous Inhuman escaped through a hole in the wall, and Johnson prepared to continue the fight. It was in this moment that Mackenzie conceived the idea of a Shotgun-Axe combination.

Fighting the Watchdogs
While on a mission to investigate the group called the Watchdogs, Alphonso Mackenzie, Daisy Johnson and Leo Fitz had their cover accidentally blown by Mackenzie's brother Ruben riding in on a motorcycle, who had been tailing his brother from their family home. The Watchdogs heard the noise, saw the light, and ran out of the barn to see what was going on. Johnson used her powers out of sight while Mack chased after his brother, who had retreated after realizing what was happening. The Watchdogs, believing that Mack was the one who had used powers, followed him and Ruben back to the Mackenzie home. After burning their motorcycles, the Watchdogs proceeded to break into the Mackenzie home and block off the exits. Mack grabbed their father's old shotgun and they proceeded to take out the Watchdogs inside the home. Eventually, the brothers reached the kitchen, and Mack found a butcher knife which he strapped onto the barrel of the shotgun, deeming it the first version of the Shotgun-Axe.

A True Shotgun-Axe
During his subsequent time at the Playground, Alphonso Mackenzie designed and finally crafted his Shotgun-Axe using a tactical shotgun and a custom axe blade. He finally found the opportunity to use it after Hive tried to turn all Humans into Primitives by using a specialized warhead inside Zephyr One. The team managed to get inside Zephyr One and Mackenzie, using the Shotgun-Axe, fought the Primitives in the plane.

During an investigation to track down the origin of a mysterious box and its contents, Alphonso Mackenzie equipped himself with his shotgun as his primary weapon. Alongside Leo Fitz, Mackenzie infiltrated a decommissioned research facility and entered a reactor room. Once inside, the pair were confronted by an intangible individual, and Mackenzie swung the axe blade at him. He continued to fire the shotgun at the disappearing man before he was trapped inside of a reactor.

Mackenzie and Phil Coulson detected Hellfire in a firework warehouse. Mackenzie bought his shotgun to the place, however he had to used it, against Watchdogs soldiers who worked with Hellfire. Coulson said that it was no smart to shot inside of firework warehouse.

Mackenzie geared himself with his Shotgun-Axe with I.C.E.R. bullets before coming to South Ridge Penitentiary prison to get Eli Morrow. As he was with Ghost Rider, the ghost Vincent appeared, so Mackenzie shot him but with no harm. After he was killed by Ghost Rider, Hugo appeared and passed through Mackenzie, therefore infecting him. Mackenzie tried to hit him with the Shotgun-Axe, but he missed all of them. So he threw it to Hugo, only to fall to the ground. After Mackenzie was cured, he used the Shotgun-Axe to open the door to save two staff members.

After the Spirit of Vengeance passed to Mackenzie, it made him ride to a Chinatown Crew hideout. Once he arrived, Mackenzie pulled his Shotgun-Axe and shot a Chinatown Crew member.

During the Battle at Chinatown Crew Headquarters, Mackenzie plugged his Shotgun-Axe on the chest of a Chinatown Crew member. Yo-Yo Rodriguez, while in superspeed, extracted the blade and moved Mackenzie's hand so the Shotgun-Axe would be pointed at another criminal. Mackenzie, to his surprise, hit the criminal.

Mackenzie walked with his Shotgun-Axe as Aida invaded the Playground. As he and Rodriguez entered the hangar, a Quinjet suddenly flew by itself and started shooting at the two. When the shooting stopped, Mackenzie fired at the Quinjet multiple times only to take cover again. Later, Mackenzie cut off Aida's head from behind.
