Chris Redfield was among the original cast intended for Resident Evil, of which only he and Jill Valentine made it to release. To make the cast of the game stand out, it was decided not to keep to a military-esque realism and have the cast appear unique. Chris' wardrobe was decided to consist of green colours to compliment the red; white; blue and black of the others. To keep to a "tough guy" image, Chris was made the more muscular of the cast and be armed with a combat knife.
Over the years Chris' basic design has changed noticeably, with Resident Evil 5 significantly increasing his arm muscles, which were lessened afterwards. His hair has also changed between brown and black.
