Pokémon

Pokémon, main element of game, are creatures which trainer has the task to catch.

Acquiring Pokémon
Pokémon can be currently acquired in two ways, by catching them in wild or hatching them from eggs obtained from PokéStops and/or Gyms.

Catching Pokémon
Catching Pokémon in Pokémon GO is bit different than catching them in games from core series, as trainer doesn't have to fight with Pokémon before he catches it. Player can catch Pokémon by coming to spot where Pokémon is to encounter it in map view and then simply tapping on it to enter the encounter screen.

Hatching Pokémon eggs
Hatching Pokémon is second way of acquiring it. To hatch Pokémon, player has to firstly get a Pokémon Egg by spinning Photo Disc of PokéStop, then basically trainer puts an egg to an incubator and has to walk specified distance to hatch it.

Pokémon collection
To enter to the page with captured Pokémon in game:
 * 1) in Map View touch Main Menu button [[file:Main Menu Button.png|30px|link=]]
 * 2) touch Pokémon button [[file:White Button Pokemon.png|30px|link=]]

Pokémon collection page on its top has to tabs - Pokémon and Eggs, that player can click on it or swipe the screen right or left to access each of them. On each of those to tabs there's shown all of the Pokémon player captured and all of the Eggs player has. More about eggs collection page is here.

Initially players have only 250 slots for their Pokémon collection, but they can expand its space by buying upgrade. Every upgrade gives 50 more slots for Pokémon and player can have up to 1050 slots for their Pokémon.

Pokémon collection can be sorted in 6 orders, that can be changed by tapping on the button in bottom left corner of screen. Pokémon can be sorted:
 * by date Pokémon were caught, the most recent on the beginning, this option is default set after login [[file:Button Sort by Date.png|30px|link=]],
 * by favourite Pokémon, which is technically same order as the one by CP but all favourite Pokémon shows up first on the list [[file:Button Sort by Favourite.png|30px|link=]],
 * by Pokédex number [[file:Button Sort by Number.png|30px|link=]],
 * by Pokémon's HP [[file:Button Sort by HP.png|30px|link=]],
 * alphabetically by Pokémon's name [[file:Button Sort by Name.png|30px|link=]],
 * and by Pokémon's CP [[file:Button Sort by CP.png|30px|link=]].

There are several optional indications shown with each Pokémon thumbnails:
 * if Pokémon is marked as favourite, there's gold star icon in the top-right corner of Pokémon,
 * if Pokémon is deployed in gym or is trainer's buddy, there's mark with an appropriate icon to the left from that Pokémon,
 * if Pokémon was caught in the last 24 hours, there's green glow behind that Pokémon.

There are three ways to exit from the page with captured Pokémon:
 * by tapping on return button on the player's mobile device (not available for iPhone users for obvious reason),
 * by tapping on the exit button [[file:Button Close.png|30px|link=]] on the bottom of screen,
 * by swiping down at the very top of the page, which cause X icon appeared and then release.

Search bar and filtering option
