Parsley City (パセリ シテイ, Paseri Shitei) is a city on Planet Earth.
Parsley City was located southeast of Metro West. Future Trunks Brief had just returned to his own timeline after training in the main timeline and reunited with his mother when he heard a special report that the Artificial Humans were causing chaos at Point BBN-49, Parsley City. Future Trunks flew to Parsley City and saw that both Future Artificial Human No. 17 and Future Artificial Human No. 18 were destroying the city, causing panic to the citizenry. Much to their surprise, he destroyed them both.
