Mama Mathers

Christine Mathers,  to outsiders and her kin, or just Mama to Fallen respectful of the Matriarch.

Personality
Even among her fellow Fallen she is described as "off", despite her obvious intelligence.

She is, by all accounts, a true believer in the ideology of the Fallen, and willing to kill members who disappointed her and their families. Mama Mathers did not permit Valefor to use his power to force everyone in her group to follow her ideology; she wanted to exercise power over people without it feeling hollow.

Mama Mathers is not a warrior or a general; she is a subtle player and would likely not be part of a headlong rush. She values her safety; she acquired or traded and paid for multiple capes who could be her bodyguards if needed. However, Mama Mathers was unable to acquire a Healer despite her best efforts and wishes.

She has a extremely regressive view of gender roles, while at the same time a surprisingly progressive stance. Anyone can occupy any position within the family they want as long as they are dedicated to the "cause" and have powers. Everyone else is disposable.

After gaining her power, Mama Mathers was grateful for the ability to hold Valefor without being his slave. Cauldron asked her for favors; she did do some of these favors as she pleased.

Appearance
Mama is an emaciated woman, heightened by her thin face and long hair that bleaching has rendered frayed and silver. This gives her the presence of an older woman, despite the fact that she is in her thirties, and makes her look fragile enough she could break. However, to people that were affected by her power she felt 'heavy'. She generally wore white, as did every other close family member of hers.

Abilities and Powers
Mama Mathers has the power to connect to and affect any sense that perceives her, which can let her leave hallucinatory imprints in the mind of anyone who perceives her. The strength of the effect and degree of control depends on how long and clearly she was perceived. The nature of the hallucinations depends on the senses through which she was perceived. If anyone registers her presence with any part of their Sensorium, including those granted by parahuman abilities, that sense is then affected. Most often, this involves auditory and visual hallucinations, though it is crucial to note that physical contact with her can result in her inflicting excruciating pain at will on her victims. Mama Mathers herself can also sense through the infected senses, including anything provided by a power.

Since sight is the most common method of perceiving her, hallucinations can often manifest as if they have a Dybbuk of her imprinted on them, like a phantom image that appears in their field of view and can take in the surroundings. This dybbuk can interact with the imprinted person through the infected senses. At the most basic, Mama Mathers appears if a subject refers to her by name with the infected sense, such as saying or writing her name. If a subject gets more exposure to her, then she also appears if they think about her or refer to her in abstract. It is unknown what her ceiling is for how many subjects she can affect, how the distance over which the connection is sustained, or how much information she can process. Regardless it is enough for her to create an ad-hoc communication network between those she has affected, and carry on whole conversations without needing to speak.

Her power acts as a harsh anti-Thinker ability that allows her to keep her kin covered from snooping eyes. The effect of her power is more intense if you use enhanced perception powers on her.
 * Valkyrie could not engage Mama Mathers and her group, presumably because Mama Mathers would affect Valkyrie's power vision and any senses from Valkyrie's shadows that perceived her.
 * After Chevalier sensed her with his power vision, she invaded that seeing and took hold of it. As Mama Mathers wanted Chevalier to join her side, she made him see specific memories of herself as well as specific visual representations of feelings.
 * When a nearby Love Lost searched for her feelings with her emotion sense to act as bait, Mama Mathers' eyes could detect and track the source of this power through a wall. She reached back before Love Lost could find her and adjusted the feelings Love Lost felt until she found the exact feeling to cause Love Lost to reel with emotion and possibly start crying.
 * According to Dinah, if she looks at her future, then Mama Mathers starts appearing in all futures Dinah can see for some time. Dinah could not act against Teacher as long as he had Mama Mathers; however, with a lot of effort, she was still able to slow him down when she could.
 * Although Mama Mathers is not on the list of blind spots for Contessa as of the Attack on Teacher, according to Tattletale, she could be considered a soft blind spot as Contessa can look but generally does not want to. However, Contessa is still capable of creating a path that involves Mama Mathers: she specifically sent Rain, Love Lost, and Colt to confront Mama Mathers' group with instructions to follow while also arranging events elsewhere so that they could successfully defeat Mama Mathers and rescue Chevalier's group without being stopped by Teacher.

She is likely a Noctis cape based on a preponderance of evidence. It is known that she can rescind her connection for a time; it is unknown what criteria are needed to reestablish it. Much like 'disconnecting' causes people to hear the sound of wings when they think of her, the effect might also be tunable to cause powerful and disabling hallucinations. People who only fleetingly register her in some way are still affected if only nominally, though this can still be enough to play tricks and distract people.

If willing, Mama Mathers can share her own senses with others by using her connections to infected senses.

Restrictions/Drawbacks
The Graeae could swap body parts out so that if someone perceived Mama Mathers with a body part (i.e. eyes, ears), Mama Mathers is only able to establish a connection to that body part's original owner.

Her connection to an infected sense is not permanent and will slowly degrade and weaken over time if a subject has not recently perceived her.

Her power can affect some technology, although does not transfer through it.
 * Lookout's flying cameras themselves were affected if they looked at her. After being sent a slice of program with facial recognition, a flying camera was told to center itself over Mama Mathers and then drop itself when the effect became worse, which knocked Mama Mathers unconscious.
 * Lookout built eye lens cameras resistant to her profile. They automatically blurred Mama Mathers, preventing Mama Mathers from establishing a connection to any eyeball with this tech. When Rain looked at her, Mama Mathers could only detect a vague buzz of technology; she noted that she had no way into his eyes.

Hallucinations do not persist while Mama Mathers is unconscious. When Victoria Dallon, who does not have an emotion sense, got close enough for her aura to extend through some hostages to a hidden Mama Mathers, Mama Mathers affected the hostages in turn. The hostages' brief change in screaming gave away her location to Victoria.

Chasmal could partially phase Mama Mathers out of reality. According to Tattletale, that should break her connections as long as it lasts and is maintained. It could even possibly force her to reset all connections.

When outside the Shardspace, Mama Mathers, despite her connections, was unable to apply her power on Rain while he was in the dream room.

Background
She was abandoned by her family because of her teen pregnancy. Her kid was an exceptionally early trigger, manifesting powers before he started walking. She was somehow found and saved by Cauldron, which offered her a deal. She was lucky enough to gain power that allowed her not uphold her side of the deal, unless she wanted to.

Joined the Fallen and presumably founded the Mathers family. Had several children from multiple different fathers, such as Valefor and the one who called himself Lionheart. She also traded children to other branches in order to get firepower back.

Mama Mathers attempted to kidnap and brainwash several Wards. One of the first of those was Sunflower, brought in by Valefor. However, Sunflower was successfully rescued by the heroes.

Post-Echidna
Her son, Valefor, attempted to claim Brockton Bay for the Fallen. Elijah failed and was blinded by the cities warlord, Skitter, in the ensuing battle. It is unknown how she reacted to this.

Timeskip
She lost another of her sons in a more permanent fashion

Mama, along with other Fallen group leaders, sent out several family groups throughout the North America after she heard about the End of the World prophecy. In order to prepare for it.

Gold Morning
Presumably participated, willingly or otherwise.

Early-Ward
With the amnesty Mama found herself in Earth Gimel with a large collection of fallen.

She was mentioned as one of main villainous influencers in the new multiversal human society.

Mama had an interview with Rain where she made sure he kept the faith and that he was staying the course with his project to kill his other trigger mates.

She was a major factor when the Fallen compound came under attack. She was captured, escaped custody, and was captured again.

Post-Fallen fall
She was being isolated in undisclosed location. Later she was freed by Teacher.

Post-Time Bubble Pop
Under Teacher's grasp, her health improved, and she actually started to look her age.

Teacher used Madam Mathers ability to entrap a large crowd of people in Earth Cheit, including local leaders. She was given free reign over them. She used her abilities to shape their beliefs in the ways of the Fallen.

During the assault on the Teacher's Compound, she was tasked with capturing Chevalier's squad, but was thwarted after her victory by Precipice, Love Lost, and Colt.

Post-Attack on Teacher
Christine Mathers had returned to The Wardens' custody.
