Kraid's design in Super Metroid is completely overhauled from his original appearance, and is later preserved in Zero Mission. His new design in Super Metroid can be credited to Toru Osawa (the creative force behind Kid Icarus), who served as a key graphic artist on the R&D1 team, and was responsible for Kraid as well as several other creatures.
Kraid was also planned to appear in the first Metroid Prime, but was removed due to development time constraints.
