O is a very tall man with a long, square shaped face, hollow eyes under prominent eyebrows, dark sideburns that go all the way down to his chin, and greenish long wavy hair. On his head, he wears a yellow and brown striped bandanna and over it is a tricorn captain's hat with what appears to be his Jolly Roger on it, a white skull wearing an animal-like hood. He also wears a dark blue, open shirt with the sleeves rolled up and a ruffled collar, and elaborate earrings made up by three little jewels each on both ears.
Abdullah has a pointed head that is bald on the top with black hair in pigtails hanging down the sides. His high forehead has three vertical scars on it. He sports thin rectangular sunglasses and along with large purple trousers held up by brown suspenders. He also has armor over his left arm.
Abdullah along with Jeet bombed a government institution, indicating a severe enmity against the World Government. He and his partner also resorted to underhanded tactics to defeat their opponents in the Corrida Colosseum, becoming very unpopular with the spectators. In spite of this ill behavior, he has shown at least to trust and respect Jeet enough to watch each other's back, as evidenced by their known history together and their brutal effectiveness as a tag-team.
