Postcognition, also termed retrocognition, is the ability to sense past events.
- Ariana Crinamorte had this ability after her brother stole the precognitive aspect of her time sensing, but later regained her full ability.
- Laila Bishop will have this ability naturally.
- Katherine Bishop possesses this ability naturally.
- In World 8, Peter Petrelli has mimicked this ability from Katherine.
- Robert Max has also absorbed the ability.
- Jessica Sky Petrelli has absorbed the ability from her grandmother.
Ariana could use the ability at will, to sense significant events about a day after they happened, and to sense information about the pasts of others. She would use this to learn more about the people she met and to keep in touch with events in the wider world. She would also use it to guide the actions of the Defining Coven. Usually, she would only gain the knowledge that an event had occured, the information appearing in her mind as if she had always known it, but she would sometimes also experience it in a vision, especially if the events were intense. The same limits remain true for the postcognitive aspect of her time sensing now.
Laila will automatically know of all significant past events, and will also sense any globally significant current events shortly after they occur. She can sense all of history, if she chooses to do so. She can choose to look into a specific person's past, or see a particular historic event. She can use this to gain information, see if a person is lying about their past, or locate a person by seeing where they've been recently.
Katherine can give herself visions of any past event at will. It was once claimed that overuse of this ability gave her a brain tumour and killed her. However, it was later revealed that she hadn't died but was in a coma instead, and that she'd fallen into this coma after using her sacrificial healing to save her daughter Elle. It is unknown if she could actually overuse her postcognition.
Robert has similar limits to Peter and Katherine. He is unlikely to overuse the ability because of possessing resistance.
Jess has similar limits to her father and uncle.
