Fong Tin Yao in MDWAV 2 never drank any fresh blood directly from a human being. I am considering the blood he drank in the end of the world not fresh because he wasn't drinking it out of the human body. I think it is "gor kei" blood or "expired/outdated" blood. I don't remember Fong Tin Yao actually sucking blood out of a person in MDWAV 2, even before he became a red-eyed vampire. So, it may be so that he didn't need to hunger for fresh human blood after he was transported back from the future. Like what kidd said, he wouldn't turn crazy like Siu Ling because he is not a Ma generation. But, he did turn slightly out of control after drinking Siu Ling's blood because he actually remembered his past life and Ma Ling Yee. That was that.Originally Posted by ice_brakerz
However, if he drank blood out of Zhen Zhen's body and saved her in MDWAV 2, I wonder if he would turn crazy like MDWAV 1. In MDWAV 1 when he actually bit Zhen Zhen, he turned into this other ugly looking creature. He did hunger for fresh human blood after that but Uncle Kao saved the day because he made special blood that could help Tin Yao diminish need for fresh human blood.
Argghh..thinking about MDWAV 1 battle between San Boon Yat Fu and Fong Tin Yao, it was a bad looking battle, no high-tech special effects like MDWAV 3.
