Corrected entry: During the final battle, Shang Tsung morphs into Liu Kang's dead brother Chan to cause Liu Kang to let his guard down. Not only does Shang Tsung clumsily do this right in front of Liu Kang, but Liu actually at first believes it to be his brother.

Correction: He knows his brother's soul was consumed by Liu Kang, so he knows Chan is "in there" somewhere. That combined with the pure emotional shock of seeing his dead brother standing before him, led him to doubt his next move. Perfectly understandable.
