Abul Abbas is a minor antagonist who appears in Metal Slug 2 and Metal Slug X. He is the leader of the Arabian revolutionaries, having made an alliance with Donald Morden. He has an indomitable fighting spirit, but tends to withdraw when things get rough.
He appears commanding the Arabians soldiers to fight, but when he see his soldiers defeated, he retreats. He appears 2 times commanding soldiers, and 1 more time while the player is fighting against The Keesi. In Metal Slug X, the Iron Nokana replaces The Keesi.
He only orders the vehicle and when the Keesi/Iron Nokana is destroyed, he takes out a white flag and surrenders.
Abul apparently has a good sense of smell, being able to detect Eri even though she was hiding.
Abul first appears in the Extra Ops "Golden Soldier", where he deploys an Assy Nero. However, he is stopped by El Dorado.
He later makes an appearance in the Extra Ops "Silent Assassin", where he is suddenly informed of a new weapon already built right beside his territory. Because of his failures, he is known throughout the Rebel Army as "Loser Abbas". Running out of ways to manipulate the situation in his favor, he decides to use his connections to the East.
Rendezvousing with Shizuka in a remote location, he manages to hire her through his bravery (staying still in the face of danger). Abul is informed by his men that an enemy unit near his territory. He decides to crush them by sending his army at them, but Shizuka stops him, as they are fighting the Amadeus Syndicate. He allows her to handle the situation.
Shizuka destroys the Toschka and Abul is informed of these events. As the Rebel Army has no idea who Shizuka is, he is sent another letter by the Rebel Army requesting his help. He thanks Shizuka for getting him back in favor of the Rebel Army and promises to use her services again when he needs it.
Abul Abbas makes several appearances in Another Story.
He first appears guarding the Big Shiee. He spots Yoshino and battles her, only to be defeated. Yoshino reluctantly spares him and rushes off to help Dragunov and Caroline with the Big Shiee, which angers him.
Later on, he invades the Sand Kingdom to build a base, with several equipment loaned by the Rebel Army such as Assy Nero. When Eri goes off and spots them working from a discreet location, Abul suddenly senses her presence and has his men pursue her. Later on, when the Regular Army attacks, Abul goes out to battle them personally. Refusing to surrender, he is defeated and retreats, preparing a trap in the process. He sends out Vita to stop them, but she is defeated. However, with her stalling the Regular Army, his men are able to prepare Assy Nero for combat. When they arrive, he sends it at them, only for it to get destroyed.
Abigail contacts him and is disappointed with him, and has her soldiers take all the loaned equipment away. She has Vita recover the core engine from the damaged Assy Nero. Abul begs Vita to take him along with her, but she refuses due to a low chance of successfully getting away with him, in addition to placing higher priority on the engine. Alone with Eri, Fio and El Dorado, he begs for mercy with them. Eri lets El Dorado do what he wants with him, so he takes Abul away so he can be punished for his crimes against the Sand Kingdom.
- In Metal Slug X, if the Iron Nokana is destroyed just as it fires its cannon, Abul will be killed.
- The Elite Arabian Soldier uses a customized model of Abul; the only differences are the color of their attire and their attacks.
