|“|| I had the pleasure of modeling and texturing Samus Aran's various armor suits, her morph balls, and many creatures for Nintendo's/Retro Studio's Metroid Prime. I also textured her weapons and Gun ship. I worked with Andrew Jones, Chris Voellmann, and Todd Keller in posing Samus for a variety of marketing images... one of which appeared to be used for First4Figures statue!
All of the concepts and marketing final paint-overs for Metroid Prime were done by Andrew Jones.
Chris Voellmann modeled her arm cannons.

Gene Kohler is a former Retro Studios artist who worked on Metroid Prime, alongside his brother Rick Kohler. Kraid, who originally was planned to appear in Prime but cut out due to lack of time, was modeled and skinned by Kohler. Kohler skinned Samus's Suits (replacing Rodney Brunet's original model), including the Fusion Suit, her Beams, Gunship and Morph Balls, as well as the Trooper Pirates and Flying Pirates. He was contributing to the development of Raven Blade for around six months prior to its cancellation, leading the modeling and skinning of the game's characters. On the game, he said: "It was a fantastic project to work on given that I favor working in the fantasy genre." 
According to Kohler, the art direction of Prime was very dark and "crude" compared to the final product, which can be seen in its earliest public images and FMV clips. Coming into work one day, Kohler received an order to recreate Samus's model from scratch in a cleaner, more refined style.
After completing Prime, Kohler left Retro to work at Microsoft on Mythica, which would itself be cancelled. Kohler was laid off, and left for Ensemble Studios. As of 2018, he is currently the senior character artist at Big Huge Games.
He was interviewed by Shinesparkers in 2010 regarding his work on Prime.
