We are very sad to report that Chikao Ohtsuka, the Japanese voice of Dr. Eggman since Sonic Adventure, first released in Japan in 1998 has passed away at the age of 85 due a Ischemic Heart Disorder.
Chikao Ohtsuka is now the third known voice actor to play as Dr. Eggman to have passed away, after Deem Bristow (English voice from Sonic Adventure to Sonic Advance 3) and Long John Baldry (English voice in the Adventures of Sonic the Hedgehog TV show).
It remains to be seen who will become his successor as Eggman in the Japanese version of the series.
Our thoughts and prayers go out to his family and friends. Rest in Peace Chikao Ohtsuka.
