Basil
Basil is a black man (or possibly an apparition) who appears when death looms for someone in the scene. Dressed in a dark coat and hat, some describe him as a cabinetmaker. Basil remains a constant presence in Makak's journey after he arrives at Monkey Mountain. He forces Corporal Lestrade to confess his sins, leading to Lestrade’s personal revelation. When the scene transitions to Africa, Basil reads the list of the accused.

Josephus
Josephus is the ailing man whom Makak heals. He suffers from a fever with no sweat until Makak saves him.

Corporal Lestrade
Corporal Lestrade manages the jail and is responsible for arresting Makak. Lestrade, a mulatto, initially identifies with white authority figures and strictly adheres to the law, showing disdain for the three black men. At the start of Makak's dream, Lestrade maintains this stance. When Moustique impersonates Makak in the marketplace, Lestrade asserts his views on law and order to Market Inspector Pamphilion. Although Makak stabs him during the prison escape led by Tigre, Lestrade later joins Makak's journey after encountering the trio on Monkey Mountain. Lestrade kills Tigre when he threatens them. In Africa, Lestrade plays an even larger role, insisting that Makak kill the apparition that initiated his journey. By the play’s end, back in reality, Lestrade is somewhat more compassionate and releases Makak.

Makak
Makak is the central figure in the play, experiencing a dream on Monkey Mountain. An older man, aged sixty to sixty-five, of African descent, he works as a coal cutter/burner in partnership with Moustique. Makak believes he is ugly and repulsive, which is why he lives alone in a hut on Monkey Mountain. At the play's outset, Makak is jailed for wrecking a local café while drunk. It is during this night in jail that he has the dream that constitutes the main part of Dream on Monkey Mountain.

Makak believes that a vision of a white woman appeared to him, revealing that he is a descendant of African royalty. She instructs him to return to Africa to reclaim his heritage. In his dream, Makak embarks on this journey and discovers he has the ability to heal, as he cures a sick man's fever. While Moustique wishes to capitalize on this power for financial gain, Makak's focus remains on his greater mission. After being imprisoned and escaping with the help of fellow inmates, Makak gains followers and by the third scene, he is a king, dispensing justice. Makak's dream concludes when he kills the apparition that initially guided him. By the play's end, reality is restored, and Makak is released from jail. Through his dream, Makak achieves a deeper understanding of himself and returns home to Monkey Mountain.

Moustique
Moustique is Makak's business partner and sidekick in the play. He is a small black man with a noticeable physical deformity in his twisted foot. Makak saved Moustique from the streets about four years prior. Moustique feels that Makak is the only one who truly believes in him. Moustique sells the coal that Makak produces. Recently, the pair bought a donkey named Berthilia for their business. In Makak's dream, Moustique has a complex role and dies twice. Skeptical of Makak's vision, he hesitantly joins the journey. When they encounter the sick man and his family, Moustique persuades them to let Makak attempt a healing in exchange for bread. After witnessing its success, Moustique immediately seeks to exploit Makak's gift for profit. He even impersonates Makak in the marketplace to earn money but is caught and killed in the process, despite Makak's efforts to save...
