Killmonger
Leader of the Superior Avengers
Origin

Killmonger was an orphan during Doom's reign. She heard tales of Wakanda being the last refuge from Doom's influence. With great pain and effort, she made it to the border of Wakanda and through a platoon of Doombots to find that the country was in fact abandoned. She decided to make herself at home, eventually getting the attention of Doom, who saw her feat as some kind of test. He adopted the young girl, training her to be one of his acolytes and outfitting her with Black Panther habit and weapons. She was once a loyal acolyte of Doom (or at least pretended to be) until she and her Superior Avengers could betray and assassinate him for being a tyrant. Later, they would pretend to be Doom loyalists again when Kristoff Vernard, son of Doom, brought them to the present. Kristoff was looking for champions from a time where Doom succeeded to prove that his reign was worthwhile. They played their roles to escape their hellish future.
Creation
Killmonger first appeared in Superior Avengers #1 by Steve Foxe and Luca Maresca as part of One World Under Doom. Her name is based on the Black Panther rival, Erik Killmonger.
Major Story Arcs
One World Under Doom

In their future, the Superior Avengers were left defenseless against an invading Annihilation Wave, because Doom had destroyed all sources of magic. When Kristoff invited them to the present, they saw their chance to horde magical artifact and create an arcane warhead they could use to destroy Annihilus. They would store these artifacts and build their weapons in the ruins of Prison 42 in the Negative Zone, far from the prying eyes of World Emperor Doom. As a distraction, Killmonger would seduce Kristoff so Doc Ock could replace her teammates with robot doubles.
To keep up appearances, they would still often go on missions doing good. When they tried to stop fugitive supervillain Graviton, they came into direct confrontation with the present's actual Avengers. In the ensuing fight, Vision seemingly mortally wounded Ghost, only to reveal that she had sent one of Doc Ock's robot doubles in her place. Ghost had secretly been a victim of these Superior Avengers, killing and switching places with the team's real Ghost before they were brought to the present. The Superior Avengers went looking for her before she blew their cover, but their hand was forced. They killed Kristoff and left him for dead, if not for being saved by Ghost, who believed Doom was a safer bet to end the Annihilation Wave in her future than the arcane warhead.
The Superior Avengers were about to take their warhead to the future when teammate, Abomination revealed he had been possessed by Annihilus the whole time. Annihilus rips out of Abomination's body and attacks these Avengers, eating Doc Ock. Onslaught and Malekith attempt to attack the enemy, but Doctor Doom arrives sacrificing both of those Avengers for weapons against the dragon. Killmonger, as the final Avenger, abandons the battlefield to go for the time platform. She is taken out by Ghost who phased her thirty feet into the dirt and trapped her in an air pocket, before running off entirely.
