Fumito Ueda, the creator of Shadow of the Colossus, originally had 48 colossi in mind when planning the game. Realising that putting in that many colossi was not possible and so he cut the number down to 24, half the original number.
Eventually, the 24 colossi became the 16 that are in the game and 8 more that were not used and are revealed in the artbook. Some are quasi-prototype versions of colossi that survived the final version of the game, other designs were discarded to improve game flow and some were cut for reasons unknown.
