Pinkie's cheerful, energetic nature becomes deeply unsettling after infection. She still smiles, laughs, and tries to "play" with others, but her behavior is erratic and detached from reality. The parasite twists her playful personality into unpredictable, childlike cruelty, making her one of the most disturbing infected.

Once calm, intelligent, and hopeful, Twilight is consumed by guilt over failing to stop the outbreak. If infected, she desperately clings to logic even as the parasite erodes her judgment. She may have brief moments of clarity before becoming paranoid, obsessive, and increasingly hostile.

Rainbow Dash refuses to believe she's vulnerable and often takes reckless risks to save others. Infection makes her impulsive temper far worse, causing sudden bursts of violence and erratic behavior while fragments of her loyalty occasionally break through.

Gentle and compassionate, Fluttershy is devastated by the suffering around her. She avoids violence whenever possible and often risks herself to help others. If infected, she becomes withdrawn and frightened, with occasional desperate attempts to warn others before the parasite completely suppresses her kindness. Rarity

Personality: Rarity tries to preserve dignity and hope even as the world collapses. She hides her fear behind grace and composure, caring deeply for those around her. Infection causes her appearance to deteriorate rapidly, leaving her horrified as her vanity gives way to despair before the parasite eventually strips away her identity.

Applejack remains stubborn and protective for as long as possible, always putting others before herself. Even after infection begins, she tries to isolate herself to avoid hurting anyone. She was with rainbow dash in a camp but stayed behind to fight of infected and ended up getting infected

Coco Pommel is one of the few survivors who escaped the initial collapse of Equestria. Though she has no formal combat training, she makes up for it with quick thinking, resourcefulness, and an unwavering desire to help others. She eventually joined Rainbow Dash and Applejack's survivor group, assisting with gathering supplies, treating wounds, repairing clothing, and keeping morale from completely falling apart. While she often doubted her own usefulness, both mares valued her compassion and level-headedness. During a routine supply run, the group was ambushed by a large swarm of infected. Forced to flee in different directions through the Everfree Forest, Coco became separated from Rainbow Dash and Applejack in the chaos. Since then, she has wandered alone, surviving by hiding, scavenging, and avoiding confrontation whenever possible. She still believes her friends may be alive somewhere and refuses to give up searching, though each passing day leaves her more exhausted, frightened, and uncertain that they'll ever reunite.

As Equestria fell to the worm outbreak, Princess Celestia concluded that the kingdom could no longer be saved and ordered a full retreat, believing preserving the remaining survivors was the only hope for the future. Princess Luna refused to accept that decision. To her, abandoning Equestria meant abandoning every pony still fighting to survive. Their disagreement quickly escalated into a bitter argument, with Luna accusing Celestia of surrendering while Celestia pleaded that staying would only lead to more needless deaths. Unable to convince her sister, Luna made her own choice. Under the cover of night, she departed alone and returned to the ruined kingdom, determined to protect whoever remained, uncover the truth behind the parasite, and search for a way to end the outbreak. Though she knows the odds are against her, Luna refuses to believe Equestria is beyond saving, carrying the weight of her sister's disappointment and the hope that there is still something worth fighting for in the darkness.
