Character profile
AI-assisted from cited sources.
Nightmare is a 5-star Caster in Arknights. This profile frames the choice around whether their documented role is worth spending limited recruitment resources on.
Biography
The reviewed English record identifies Nightmare as a playable Caster Operator and connects the unit to Recruitment & Headhunting. It does not infer gender, faction, or personal history from artwork, names, or community descriptions.
Lore
The available structured record describes Nightmare through their operator identity and in-game recruitment context. Pull or Skip keeps that limited evidence separate from fan interpretation and does not invent relationships or story claims.
Gameplay and banner context
Nightmare is classified as Caster with the source tags DPS, Healing, Slow. Those labels explain the unit's broad battlefield purpose, but they are not a tier ranking and cannot replace a player's roster, stage, or investment needs.
The linked Global evidence supports Nightmare's eligibility in the live catalog. A PULL decision should still consider banner availability, pity, duplicates, and the opportunity cost of saving for a later Operator.
Voice actors: Elivia (CN_MANDARIN), Rie Takahashi (JP), Yi Sae-ah (KR), Triya Leong (EN)
