In the Emerald version of the Pokmon game series, the creature occupying the final slot, number 202, in the regional Pokdex is Chimecho. This ordering is not arbitrary but is a consequence of the game’s data structure and the order in which Pokmon are encountered and programmed into the system.
The sequential placement within the Pokdex often reflects a combination of factors including the discovery order, the availability of Pokmon throughout the game’s storyline, and the overall game design considerations. Having a specific Pokmon at the end doesn’t necessarily imply greater rarity or power, but it does mark the completion of the Pokdex for many players, adding a sense of accomplishment to their gameplay.
