Pokemon GO Resource Pack PokePack was made by the austrian PvP Texture Pack creator Jaba. It is meant to be used with Minecraft version 1.8.9, 1.8.8, 1.8.6 and most previous versions.
First of all it's not the only Pack of JabaPacks which is being hyped that much. Here's a selection of some very popular Minecraft PvP Texture Packs Jaba published before the PokePack Animated went viral: 3D Animated CSGO Pack, 512x512 1k Pack, Future Pack and KRATOS Pack (Around 300.000 Downloads). The community loves his texture packs.
The only bad thing about this pack is that it might not work well with Minecraft 1.8.0. If Pokemon Go PvP Texture Pack doesn't work well with Minecraft 1.8.0 you should use Minecraft 1.8.2 or newer.
