Editing Pokémon
The Pokémon section allows you to view and edit the data of every Pokémon in the game. However, not every Pokémon-related edit is under this section.
Pokémon Data
Most all data and properties of any given Pokémon can be edited under the "Pokémon" dropdown tab within SkyTemple. From there, you can edit the data and properties of the individual gender forms of each Pokémon by double clicking on the form you want to edit.
Talk Group
Talk Groups are used to determine the dialogue an allied Pokémon will use within dungeons and Spinda's Café. The group used by each Pokémon ID can be seen in their General tabs, and the dialogue strings can be seen by double clicking on the main Pokémon drop-down and selecting the Personality Groups tab.
Im-/Exporting Pokémon
SkyTemple allows to export or import Pokémon Data. To do that, select the slot you wish to export data from (or import data to) and select Export or Import, depending on your needs.
Personalities
Personality is given to the player by the Personality Quiz at the beginning of the game. What Pokémon has which personality is determined under Lists -> Starters.
