Powers
For more information, see Kay Challis' Alters.
 * Mutated Alters: After being sexually abused by her father, Challis developed 64 split personalities and was later experimented on. As a result, Challis developed Metahuman powers and each alter was given a set of abilities.
 * Shapeshifting: When an alter surfaces, Challis' appearance alters to the personality in charge. This varies from hair color, hairstyle, voice, and tattoos.
 * Longevity: While Challis herself does not possess any exceptional powers as her alters do, Challis' body does not age like other human beings and was able to maintain her appearances for over 50 years.
 * Superhuman Sonic Scream: When Challis saw the truth about the disappearance of the alters, The Underground started to fall apart as Challis screamed at a high pitch. Her surface self soon fell into the same situation and sent out a powerful shockwave that flipped the Doom Manor School Bus over with ease.

Abilities

 * Bilingualism: Challis is fluent in English and Spanish.

Weaknesses

 * Dissociative Identity Disorder: For decades, Challis was unable to effectively communicate with her alters, causing harm to those around her without any means to stop them. Challis later developed psychological issues, leaving her vulnerable and distrustful on others before Jane could develop a strong bond with her.
