Primal rage is the ability to induce an instinctive and uncontrollable rage in others, as well as suppressing their conscious thinking.
- Ricardo Silva is the only character known to have this ability.
When using his ability, Ricardo's eyes glow red. While the full extent of his ability is still unknown, he appears to be able to affect those in his proximity. Once affected by this ability, the victim appears to be overcome by an uncontrollable rage, fear, and sense of survival, which causes him or her to attack those nearby. The victim's rationality is also affected; most do not remember well what happened to them.
According to Mohinder, this ability operates by strengthening the instinctive, animal part of the mind, while weakening the higher-form, conscious aspect of the mind. He suggests that, if the cognitive functions of a person were impaired, Ricardo would be able to use his ability much more easily, allowing him to transform crowds into angry mobs.
