Rayssa Tavares is a Brazilian former model turned vigilante, serial killer, spree killer, and torturer. A feared member of the ISG, she primarily operates in Rio de Janeiro, targeting Comando Vermelho members, Brazilian militias, and corrupt police officers. Known for her intelligence and ruthlessness, she has managed to outsmart even BOPE units, earning a reputation as one of Brazil’s most dangerous underground figures. Many speculate she played a leading role as the “main head” behind the gruesome death of Alexandre de Moraes. One of her most infamous nicknames is “Noturna” — “Nocturnal” — a name inspired by her preference for striking under the cover of darkness and vanishing without a trace.
