Twinfish is a Fish in NieR: Automata.
"Caught in a river. Can be exchanged for money."
- "A two-headed freshwater fish that resembles an arowana, but is actually a different species entirely. The upper head constantly surveys the environment for threats, while the lower head searches the river bottom for food. Both heads are capable of independent thought, and its life span is said to be greatly affected by how well they get along."
