Yoshihiro Sakaguchi

Yoshihiro Sakaguchi, better known by his pseudonym:Yuukichan's Papa, was the co-composer for Mega Man (along with Manami Matsumae) and Mega Man 2 (along with Takashi Tateishi and Manami Ietel). He has also worked on quite a few of Capcom's other classics from the late 80's including the original Street Fighter from 1987, and Final Fight. He left Capcom in the mid 90's, and today, he appears to have some kind of involvement with the Mobile Suit Gundam franchise.
