I wa sactually hoping that Prime or Zero Mission remake would use 3d/updated versions of the original designs for Kraid and Ridley. Super Metroid made them both a lot more reptilian. Kraid looked like some sort of bizarre demon and Ridley looked like the xenomorphs from Alien. Although I did like the idea of them both being intelligen/ officers in the pirate army rather than just aggresive monsters/attack dogs.
