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, hiring the assassin Shizuka to regain favour with the Rebel Army.
In "Dancing Brave", he was going to have Shizuka destroy the Ptolemaic Union 03, though Aisha interrupts and asks him to assign the task to her. After some praise that causes an awkward moment, he allows her to go. When she returns, Abul thanks her, which she interprets as praise and causes another awkward moment.
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.
He later attempts to build a new base in the Sand Kingdom with Assy Nero (being similar to that of the Extra Ops "Golden Soldier") but is foiled by El Dorado and the Regular Army, and is apprehended.
Abul seems to have escaped El Dorado, resuming his war with the Regular Army in his own nation. As he regained the Rebel Army's trust, he was given the Tani Oh to defend his territory. He later returns to base and saves Shizuka from the Ptolemaic Army, though he had to abandon the Tani Oh.
- 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.
