NPC Editor

An NPC editor is an item that is used to create and edit NPC Trainers and chatting NPCs. When used on the ground, it will present the option to create a new Trainer or a new chatting NPC. When used on an existing Trainer or chatting NPC, it will open a GUI where the NPC can be edited or deleted. The NPC editor has the same inventory sprite as the Old Rod.

While the player is holding an NPC Editor, NPC Trainers cannot challenge or be challenged by the player.

Skins

A Trainer's skin can be customized to look like any of the available NPC Trainers. External skins can also be used for the Trainer by selecting the "Steve" option, causing a second button to appear with more customization options.

"Custom_RP" allows a skin to be selected from a currently used resource pack; the skin must be located inside the resource pack at assets/pixelmon/textures/trainers/steve.
"Custom_PN" allows any player's skin to be used as the Trainer's skin. The chosen player does not need to be on the server to use the skin.
Pixelmon also includes five default custom skins (prisoner, Santa, Scottish, Steve, suit) that can be used.
