Invisibility

From The 4400 Wiki, a fan encyclopedia that anyone can edit.

Invisibility is a promicin-induced ability that allows its user to remain unseen and unheard by others in proximity. However, this ability, while it can be activated by concentration and can be expanded to make other invisible, is limited, as it only functions while its user remains completely still, otherwise the invisibility field the person is creating would shatter if the user moves.

Enhanced Soldier Captain Aquino had this ability.
