His right head, Bakool Ja Ja the Mighty, is the dominant half while the left head, Bakool the Mystic, is subservient to his brother. As a whole, Bakool Ja Ja views himself in high regard as per his kind's tradition that twin-headed Mamool Ja are "blessed siblings". Using his status as a two-headed Mamool Ja to elevate himself above others at every opportunity, he spurns any other faction or race, including his own kin, showing distaste for one-headed Mamool Ja. Bakool Ja Ja is arrogant and overconfident when facing his opponents, leading more skilled, level-headed, and experienced foes to easily defeat him, wounding his pride. He also shows some prejudice towards other races, having been constantly told that as blessed siblings, they were superior to everyone around him. This prejudice stems from his father, Zereel Ja, who aspires to see the Mamool Ja be the dominant race in Tural. Despite his arrogance, Bakool Ja Ja has enough perception to notice and acknowledge the threat of some of his opponents, such as the Warrior of Light, believing them to be more of a problem to his efforts than Wuk Lamat herself.

Relying on his brute strength and cheap tactics, he puts little thought into tasks for the keystones in the competition for the Rite of Succession, continuing with the knowledge that he could take the keystones from the other claimants by force. This makes him heavily disliked and viewed with contempt by the other claimants. Wuk Lamat observed that Bakool Ja Ja had enough skill to win the competition had he been more confident in his own skills rather than resorting to dirty tactics.

His obsession to claim the throne by any means necessary results in him breaking down when his tactics fail, as shown when he is thwarted by Wuk Lamat, which prompts him to run away in panic. This obsession stems from his circumstances as a two-headed Mamool Ja, with mounting pressure placed on him by the people of his home and their struggles. Bakool Ja Ja's efforts in the contest were merely a means for Bakool to prove his worth and validate his "blessed" status.

He is aware and remorseful towards the tragic nature of two-headed Mamool Ja, although the apparent dire circumstances of his home prevent him from seeing any other recourse. Bakool Ja Ja displays a strong level of survivor's guilt, not wanting to fail not only to help his people, but also ensure that his siblings' deaths were not in vain. When Wuk Lamat and her party confronts Bakool Ja Ja's truth, Bakool Ja Ja shows he is genuinely remorseful while also fully aware that it would be near impossible for anyone to forgive his actions. When Mamook is shown that they can still prosper in their environment, their opinions towards "blessed siblings" changes significantly, resulting in Bakool Ja Ja being more receptive to peace and understanding with his burden being lifted.
