Nightmare

Nightmare, whose real name is Ribel Pasbeletti Gloria, is a Caster operator in the mobile game Arknights. She is an infected individual suffering from Multiple Personality Disorder, with two distinct personalities: the meek-mannered 'Gloria' and the aggressive 'Nightmare.' Gloria was once a student in Victoria, majoring in medicine and psychology, but after contracting Oripathy, her personality began to split. The Nightmare personality possesses powerful Originium Arts, capable of attacking, healing, and slowing down enemies. Her Skill 1, 'Drain Soul,' allows her regular attacks to heal nearby allies while increasing her dodge rate. Her Skill 2, 'Night Phantom,' inflicts a unique debuff on enemies, dealing true damage based on the distance they move. While Nightmare has a high base damage, her skills are situational, making her a niche support operator unsuitable for new players. In the game, she can be obtained through Headhunting or Recruitment. Nightmare's complex personality and backstory provide players with a deeper layer of exploration.
