Batwing is a representative of Batman Incorporated from the city of Tinasha, within the Democratic Republic of Congo.
When David Zavimbe was a young boy in Tinasha, his parents died of HIV/AIDS very early in his life. Following the death of their parents, David, and his brother, Isaac, were taken from their orphanage and drafted as boy soldier prodigies, like many children his age, into General Keita's army known as the Army of the Dawn, for a war that ravaged his country. While many young boys were picked to join, the Zavimbe brothers shined above the rest with their ability to take orders and kill and garnered the name the Dragonflies. Due to their speed, dexterity, and prodigious ability to kill, General Keita promoted the boys into the ranks of his elite men.
On Keita's path to power and domination, he orders the brothers to kill Okuru, one of Keita's major enemies. They agree to sneak in and slit Okuru's throat, but Keita demands they torch the entire village to prevent any possible escape. Refusing to kill innocent women and children, Isaac shoots his gun in the air, giving Okuru and his squadron time to fire shots back, forcing Keita to retreat. The General cannot stand for any insubordination and while he is arguing with David, Isaac hits him over the head with a rock. Keita reaches for his machete and slices Isaac multiple times; all the while, David is sprinting away.
Later that night, David sneaks into Keita's room and drugs him before he can make a move. Eventually, Keita comes to be tied up in the back of an SUV. David says he will not kill any longer and drops Keita outside of Okuru's new encampment, while firing shots in the air to notify them.
After General Keita's death, David spends the next few days walking to the Children's Harbor, an orphanage for former child soldiers. David was able to escape the life of being a soldier at such a young age, and soon became a police officer in Tinasha, where despite corruption running rampant, he remained dedicated to the law and justice. Elsewhere in the United States, Bruce Wayne announces Batman Incorporated, an initiative to put Batman-like figures in countries all across the world. Soon after that, Batman pays a visit to Tinasha, where he inducts David as the newest member of his team in his quest to stop the global terrorists, Leviathan.
Shortly after finding the false Dr. Dedalus and coming into confrontation with Leviathan yet again, Batman travels to an unknown destination within the continent of Africa to recruit a new member to his team of Batmen, Batman Incorporated. Batman leads David through his first mission for Batman Incorporated, providing a technologically advanced bat-suit. David comes into contact with a Leviathan brain-washing cell, narrowly avoiding capture once his presence is compromised. During his escape, he demonstrated a knowledge of martial arts, also showing off special capabilities of his bat-suit including jet propulsion.
Batwing faces off against a new villain calling himself Massacre. As Massacre gets the upper hand in battle against Batwing, we see a flashback of Batwing stopping Blood Tiger, a former captain of a warlord and now in control of a drug ring. With the help of Batman he manages to capture him.
As his investigation continues, he comes upon a gruesome crime scene with beheaded bodies. Later, as he researches it with the police, he finds a room filled with murdered police officers and he gets stabbed in the back by Massacre as he looks shocked at the murdered officers. David attempts to fight back his attacker, but he quickly loses. Massacre attempts to finish David off, but is interrupted by Kia Okuru and other officers who fire shots at him. David passes out during the shootout and wakes up two weeks later in The Haven. He asks Matu to see about the shootout and the welfare of Kia Okuru. Matu informs him that Kia lives, but she had been badly beaten and the rest of the officers had been killed. David attempts to go after Massacre shortly after he awoke, but Matu urges him to remain in The Haven to heal up his injuries and regain his strength.
They both argue about it for a bit before Matu forces David to get back to bed. David soon knocks out Matu with a tranquilizer dart and goes after Massacre. He is able to deduce Massacre's location from something Massacre had said to him back at the police station. He arrives just in time to aid Thunder Fall of The Kingdom, who is engaged in a brutal battle with Massacre. Despite his injuries, Batwing, along with the help of a severely injured Thunder Fall manage to fight and then escape from Massacre to a nearby hospital where Thunder Fall reveals that The Kingdom, a super hero team which operated in Africa, had done something terrible and that Massacre was their punishment.
The final truth is revealed after the heroes rescue The Kingdom's tech-powered member, Steelback. He tells them that years ago, The Kingdom was fighting the ruthless dictator of Congo alongside the People's Army, which left him only with the capital city to defend. Intending on this to be a victory of the people, they left the army to go alone, but soon received a message saying the dictator has allied himself with the African crime lords, making it impossible to win even with The Kingdom's intervention. The heroes are forced to give amnesty to him and promise no retaliations after that. The crime lords fought anyway but without the dictator to support them, their army of child soldiers was slaughtered, and 50,000 lives were lost in the battle. This tragedy led to The Kingdom's subsequent dissolution.
After the events of the bomb attack at the United Nations place outside, Booster Gold was very sad that the team has lost some of the JLI members who were killed and hurt very badly. Booster was fighting off a villain and was hurt and he saw someone he thought was Batman, but it was Batwing who came to help the team. Batwing was briefly a member in the JLI until the series came to an end with Justice League International Annual #1.
Batwing has joined with the team calling themselves the Dead Heroes Club, an off-shoot of Batman Inc.. The other members are Looker, Freight Train, The Hood, Gaucho, Wingman, and Halo.
