Mato Gallery
Scans of Green/Blue from Pokemon Adventure. I know he's a different character, but Shigeru and Green look practically the same. Plus, I didn't know they were different when I first bought the manga. So I scanned them. Boo ya.

Toshihiro Ono Gallery
Scans of Shigeru from The Electric Tale of Pikachuu.

Satoshi Tajiri Gallery
