Egg Moon Saga
Tanaka is calm, composed and very dedicated to his job. He cares very much for the well-being of Chris and his family and has risked life and limb for them on several occasions.
In the English dub, he speaks with a stereotypical Japanese accent.
Powers and abilities
Mr. Tanaka is a skilled martial artist (though in the English dub, this is apparently because he watches "too many Kung Fu movies").
Sonic the Hedgehog
Even though he is a good friend of Sonic the Hedgehog, Sonic holds him in low contempt and does not like it when he goes on adventures with him, believing that he is not useful. This may be because he usually hinders Sonic more than he helps when he tries to assist Sonic.
- The French dub of Sonic X switches between the usual Tanaka name and "Édouard". It is likely that his name was intended to be completely localized in this language, but the translators may have been sloppy with their efforts.
