From Bulbapedia, the community-driven Pokémon encyclopedia.
Kei Hoshiba (Japanese: 保志場慶) is a 3D graphic designer primarily involved with the development of character models in several early Pokémon titles and more recently, environment design on the latest titles. He has also produced artwork for a number of cards in the Pokémon Trading Card Game, though is often credited as K. Hoshiba.
Work for the TCG
Initially, Hoshiba's early TCG artwork was a collaboration between himself and CR CG gangs; Hoshiba likely providing the base model while CR CG Gangs added details, etc. His solo artwork primarily consists of 3D Pokémon models that appear to be based on those in Pokémon Stadium and Pokémon XD: Gale of Darkness – titles that he worked on, though with various lighting, elemental or movement effects added to give the final image more presence. Perhaps more notable is that he provided the art for the new No. 2 Trainer and No. 3 Trainer TCG World Championship trophy cards, which take inspiration from the original Japanese tournament prizes. The illustration has remained in use for every Worlds incarnation since. For a list of all cards he has illustrated, go here.
