GPX+ implements a rarity system that makes certain Pokémon eggs more easily encountered than others. Similar to the video games, this system is set in place to encourage players to hunt for more valuable Pokémon in the lab, or engage in Pokémon Breeding to share already-obtained Pokémon with other users. In this way, users must expend a bit more effort to obtain rarer and more sought-after Pokémon and complete their Pokédexes.
GPX+ currently implements five rarities: Common, Uncommon, Rare, Very Rare, and Novelty. The first four tend to reflect the rarities of Pokémon found in the video games, also called 'canon' Pokémon on GPX+. The latter corresponds to the unofficial Novelty Pokémon created by the staff and contributors of GPX+.
A Pokémon's rarity is reflected in how often its egg is spawned in the Lab or created through Breeding; the more common the rarity, the more likely it will appear in either the Lab or the Daycare Center. In this way, Novelty Pokémon also have a "secondary" rarity that reflects how often the Pokémon's non-novelty form, if any, will be generated in the Daycare Center, according to the rules of Breeding implemented in GPX+.
On the Pokétch and Pokédex, the Common rarity is symbolized by a Pokéball icon.
- Main article: Ditto
Currently classified as a Common Pokémon, Ditto was once classified as Rare, and is to date the only canon Pokémon whose rarity was changed. Despite this, it is one of the more sought-after Pokémon on the site, desired for its ability to breed with any other non-Very Rare Pokémon. Consequently, it's appearances in the Lab are brief; it was once rumored that, in order to curb hoarding, once its Egg and Pokédex entries had been obtained, it could not be found in the Lab or Egg Shelter again, though this has since been disproven by users. Instead of stalking the Lab or Shelter to try and find one, users can partake in the Transforming the Heart exploration, which awards a Ditto egg once completed.
On the Pokétch and Pokédex, the Uncommon rarity is symbolized by a Great Ball icon.
- Main article: Unown
All 28 Unown are present in GPX+, each with their own Dex entries, and are classified as Uncommon. However, like Ditto, they are also highly sought-after; all Unown share the same Egg description, so their appearance in the lab is often brief as users attempt to fill their Pokédexes. Their inability to breed makes their scarcity that much more prominent. The Mystery Creature of the Ruins exploration awards one random Unown from those that the user does not yet have an Egg Dex entry; otherwise it will award one of the 28 Unown eggs randomly.
A special case here is Phione. Although it is related to Manaphy, a Very Rare Pokémon, and in many video game sources is labeled a Legendary Pokémon, Phione is classified as a Rare Pokémon. Thus, it can appear in the Lab with the same frequency as any other Rare Pokémon, and follows the same breeding rules as other Rare Pokémon.
On the Pokétch and Pokédex, the Rare rarity is symbolized by an Ultra Ball icon.
Very Rare PokémonEdit
- Main article: Very Rare Pokémon
On the Pokétch and Pokédex, the Very Rare rarity is symbolized by a Master Ball icon.
- Main article: Arceus
The Alpha Pokémon is awarded special status on GPX+, as it can only be obtained in the lab (appearing even more infrequently than other Very Rare eggs) or through special vouchers awarded to contest winners. To date, at least 13 are known to exist on the site.
- Main article: Novelty Pokémon
On the Pokétch and Pokédex, the Novelty rarity is symbolized by a Cherish Ball icon.
