Chunyan is a new character introduced in Metal Slug Attack.
She is a martial arts fighter and a chef, known for her dumplings. Prior to joining the Ptolemaic Army, she was a waiter at a restaurant. Veronica and Sisilia would intervene when a customer started harassing her, and she cooked them a meal in thanks. Appreciating her cooking, Chunyan was offered a spot in the Ptolemaic Army, which she accepted.
She enjoys eating the dumplings she makes and often carries a lot of them on her. Despite eating so much, she manages to stay slim with vigorous exercises.
First debuting in "Kung Fu Guru", Chunyan accompanies Dragunov and Yoshino on a mission to infiltrate the Amadeus Syndicate's headquarters. She realizes that they have infiltrated too easy and the three are ambushed by an AI resembling Amadeus. Chunyan lands a blow on the AI, which initially looks as if it failed to deal damage, but Amadeus himself soon arrives and states that she damaged the main computer. As the three escape, Dragunov laments on the mission's failure, while Chunyan gets hungry and decides to make dumplings to cheer herself up, with the two officers joining in.
