Out of the three apes s/he conspires with, Mortolo is the second largest. Like the other apes, his/her fur is light brown, and two fangs protrude from his/her bottom lip, which is riddled with freckles.
Mortolo is very menacing, lazy, and smug but fearful when confronted with death.
Mortolo and three other apes block the river by making a dam to force Mufasa and his pride from the Pride Lands by depriving them of water. The gorillas scheme to do this so that they can take over without having to fight for the territory. Simba foils their plan by creating a rock slide and causing them to run off.
