Hey look I finally made a place for Tanglemane to fit in my universe :D
In my story he is Selfish's friend and between the two of them they cause much trouble for Mohatu. Tanglemane doesn't truly understand the reason behind Selfish's antics, only that he goes along with them because he has nowhere else to go.
Tanglemane's alliances change when he meets Asabi and falls in love with her. Though he approached her, it was met with no success as Asabi was unfriendly towards him upon finding out that he had ties to Selfish. Despite the rebuff from her, Tangle could not get rid of her in his head, and so he continued to admire her from afar.
When he heard that Selfish killed Asabi, he switched sides immediately and chased down Selfish after Mohatu chased the older lion off. Once he cornered his former friend he killed him, but Selfish left his mark by giving Tangle four deep scars to his forepaw. Now no longer having a reason to stay, Tangle leaves, and his fate is left unknown.
