Hung is a heavy defender from Lee's Detective Agency recommended to Rhodes Island by Mr. Lee. He provides reliable front-line protection for other Operators with his massive physique and extreme strength. The Lungmenite Perro named Ko Hei-sing was originally a security guard of a company who was fired due to his rather friendly yet timid character. In the midst of his misery and hunger, he coincidentally encountered Mr. Lee and was brought under the care of the Lee's Detective Agency.
