Thang Shin was the lover of Hamato Yoshi and the target of Oroku Saki's affection. Fleeing from Saki's jealous rage, Yoshi and Shin took their pet rat Splinter to New York City. Saki followed them and killed Shin, leaving her corpse for Yoshi to find. Saki appeared to the stunned Yoshi and wasted no words, killing his rival as well.
Unlike most versions of Tang Shen, the film called her by the similarly-spelt name "Thang Shin." The name "Thang" is pronounced the same way as "Tang."
