Abul Abbas is the leader of a group of Arabian revolutionaries and a minor villain from Metal Slug 2 and its remake Metal Slug X.
He made an alliance with Donald Morden, who provided him with resources, allowing him to take over an Arabian city.
The heroes arrive on the city and fight the Arabian forces commanded by Abul, who then calls upon the VTOL bomber "The Keesi" to fight then. After The Keesi is destroyed, Abul Abbas surrenders by using a white flag on his sword.
Abul Abbas appears throughout the first mission rallying the Arabian troops and then retreating when they are defeated. During the fight with The Keesi he keeps swinging his sword to call upon troops that come from inside the VTOL.
