Hiromichi Sugiyama, CR CG gangs appears in the Pokémon TCG credits from 2000 to 2002, with two known cards in the Neo series. The credited work is found across Neo Genesis and Neo Destiny, including character and Trainer illustration within this compact span.
Across these appearances, the visual approach reads as digital and illustrative with geometric structure: simple, focused staging and balanced layouts that keep attention tightly on the subject. Moods skew calm and serene, occasionally edged with a playful, futuristic note. Color handling shifts between cool, muted passages and sharper contrast, allowing vibrant accents without crowding the frame. A representative card is Porygon (Neo Destiny).
