Koichi Yamadera

Spike Spiegel.

Yamadera-san is more than that, of course. He usually voices cool men (Besides Spike, Kaji from EVA counts as well), but what makes him such a famous VA is his ability to just do ANY type of characters, including Donald Duck and "Boxer" (Balrog/Mike Bison). He also has dubbed actors for American films dubbed into Japanese, including Jim Carrey, Eddie Murphy, and Robin Williams. He was married to fellow seiyuu Mika Kanai, from 1994 to 2006. He is also a skilled "monomane tarento" (impressionist), as his appearances in the variety show Monomane Grand Prix would prove.
