"Ridley-2 (or possibly Ridley-Z) is an unused Ridley form from Metroid: Zero Mission which possessed a third claw on the end of his tail, likely for grabbing Samus with extended reach. He also appears to have wings on his arms as opposed to their own separate pair of limbs. This form was only seen in concept art and may not have made it past that stage of development. : Non-canonical information ends here."@en . "Ridley-2"@en . . . .
