The Pixelmon Mod has always been just for PC. Until now. We are in the midst of having a breakthrough in mods for the Pocket Edition version of Minecraft because of Add Ons.
How do I get the Pixelmon Add-On for MCPE?
To get the Pixelmon Add-On you simply need to download the resource pack and the behaviour pack. Then you will need to start a new world on Minecraft and choose the Pixelmon resource pack and behaviour pack.
To get the mod on PC you will simply just need to download the .jar file and add it to your Mods folder. That’s after you have installed Forge for that version. More on that on the Pixelmon for PC page.
