Hsien-Ko (シェンコ Shenko, Chinese: 贤哥) (Lei-Lei (レイレイ Reirei, 蕾蕾) in Japan) is one of the main heroes that was first introduced in Night Warriors: Darkstalkers' Revenge along with her older twin sister, Mei-Ling (Lin-Lin, リンリン, Rin-Rin in Japan). Her character is based off the Chinese hopping vampire, also known as a Jiang Shi (also known as a Kyonshi in Japanese) of Asian myths. She has appeared in many cameos such as Ken's party from the Street Fighter series, and many Capcom and Namco games such as Super Gem Fighter Mini Mix (Pocket Fighter), Namco × Capcom, Project × Zone, and Marvel vs. Capcom 3/Ultimate Marvel vs. Capcom 3. Hsien-Ko was originally voiced by Michiko Neya before being replaced by Saori Hayami in Marvel vs. Capcom 3, while her English voice provider starting from the same game is now Hunter MacKenzie Austin as well. In the Night Warriors: Darkstalkers' Revenge OVA, she was voiced by Yūko Miyamura in the original and by Nicole Oliver in the English dub.
